By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) 19yy name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

VNC +over STUNNEL with a Linux server and Windows 2000 client HOWTO

+


+

+

19 February 2001

+

ver 1.0

+

by Craig Furter and Arno van der Walt

+

contact us at cfurter@vexen.co.za +and arnovdw@mycomax.com

+


+

+


+

+

We assume that you have already +downloaded VNCServer and VNCViewer.

+


+

+

First of all there is a step by step +HOWTO and then we'll look at the theory behind all this.

+


+

+
    +

  1. Download and install openSSL, + SSLEay, and Stunnel on the Linux/Unix box. Download the modules.

    +
+

a) +[root@anthrax$]gunzip openssl-x.xx.tar.gz (repeat for all 3 the +modules)

+

b) +[root@anthrax$]tar – xvf openssl-x.xx.tar (repeat for all 3 the +modules)

+


+

+
    +

  1. Copy the following to Notepad and + save the file as VNCRegEdit.REG on the Windows 2000 box

    +
+

--cut here and copy +to VNCRegEdit.REG the double click file to +import--
REGEDIT4

[HKEY_LOCAL_MACHINE\Software\ORL\WinVNC3]
AllowLoopback=dword:00000001

[HKEY_LOCAL_MACHINE\Software\ORL\WinVNC3\Default]
AllowLoopback=dword:00000001
--stop +here--

+

+


+

+
    +

  1. Install Stunnel on the Windows + 2000 machine by copying the following files to your \WINNT\SYSTEM32\ + directory

    +
+

a)libeay32.dll

+

b)libssl.dll

+

c)stunnel.pem

+


+

+
    +

  1. On the Linux box execute the + following command as root and let it run in its own terminal.

    +
+

./stunnel -d 5900 +-r 5901

+


+

+
    +

  1. Execute vncserver (it should run + as display:1 when you execute the ps aux |grep vnc command)

    +
+


+

+
    +

  1. Now on the Windows 2000 machine + execute the following command and let it run in its own terminal.

    +
+

stunnel -d 5900 -r +unix.ip.adress:5900 -c

+

.

+
    +

  1. And on the Windows 2000 machine + open VNCviewer and connect to localhost specifying no display

    +
+

ie. 10.10.1.53 in +the window

+


+

+
    +

  1. For each additional display repeat + steps 4 – 6 and increment the specified ports with 2 ie. The + Linux command will look as follows:

    +
+

./stunnel -d 5902 +-r 5903 +

+

and the Windows +2000 command as follows: +

+

stunnel -d 5902 -r +unix.ip.adress:5902

+

and remember to +start another vncserver on the Linux box for each VNC display

+


+

+


+

+
    +

  1. The display number on the + vncviewer must also be incremented with two ie:

    +
+

10.10.1.53:2 etc.

+


+

+

The THEORY

+


+

+

Tunneling:

+


+

+

What this means is that software +(daemon) runs on the client and server machine. In this case, the +Windows 2000 machine is the client and the server is the *NIX +machine. Stunnel will then run as client on Windows 2000 and server +mode on the UNIX box.

eg:
Windows:
stunnel -d 5900 -r +unix.ip.address:5900 -c

UNIX
stunnel -d 5900 -r 5901

This +means that connecting to VNC display 0 in the localhost will transfer +all the calls to the *NIX machine on display 1. So the VNC server on +the *NIX machine must be running on display 1. Not display 0. If you +run stunnel before VNC, VNC will automatically move to display 1 +noticing that port 5900 ("display" 0) is already in +use).

What happens now is that when you connect to port 5900 +on the Windows machine via an "unsecured" connection, a +secure "tunnel" is opened from Windows 2000 to the *NIX +machine on port 5900. The *NIX machine then opens a "unsecured" +connection to itself on port 5901. We now have a secure tunnel +available.

+


+

+

A bit about VNC and displays

+


+

+

The -d is the listening IPaddress:port +and the -r is the remote IPaddress:port. VNC uses port 5900 for +display 0. That means that display 1 will be 5901. If you want VNC +server to listen for a connection on port 80 then the display number +will be 80 - 5900 = -5820. If you want VNC server to
listen on +port 14000 then the display number is 14000 - 5900 = 8100.

So +all you have to do is run stunnel on the UNIX machine and VNC on the +desired "display" number.

+


+

+

VNC on the Windows 2000 machine

+


+

+

To connect from the client machine you +need to enter the client machines IP address and the "display" +(from the port conversion). But VNC will think that you are trying to +connect to the local machine and does not allow this. To override +this add the following to you registry.

--cut here and copy to +anything.reg. the double click file to +import--
REGEDIT4

[HKEY_LOCAL_MACHINE\Software\ORL\WinVNC3]
AllowLoopback=dword:00000001

[HKEY_LOCAL_MACHINE\Software\ORL\WinVNC3\Default]
AllowLoopback=dword:00000001

Now VNC will not complain. So you need to always run +stunnel in client mode on the Windows machine and then connect with +VNCViewer to the localhost on the correct "display". By the +way, *NIX doesn't complain about this. There is no setting needed if +*NIX to *NIX.

+


+

+

VNC's Java client

+


+

+

Unfortunately this will not work well +with the build in web version. If you did not known about it, try +http'ing into a machine running VNC server on it, to port 58XX (where +XX is the display number), and the Java client will be loaded.

certyfikatw klienckich winno mie si na uwadze wredn cech produktw +M$ dostpnych poza granicami USA. +

oczywicie naley dobrze chroni i najlepiej jest gdy znajduje si +na serwerze tylko w momencie generowania certyfikatu. +
Ponowne uruchomienie CA.pl z parametrem -newca niszczy to co pracowicie +stworzye i generuje nowy klucz i certyfikat. +
  + +

Tworzenie certyfikatu dla stunnela i innych serwerw +
  + +

Zanim si do tego zabierzesz powiniene lekko zmodyfikowac skrypt CA.pl +oraz plik konfiguracyjny openssl.cnf. +
Skopiuj je odpowiednio do plikw /usr/local/ssl/bin/CAserv.pl +i /usr/local/ssl/lib/openssl_serv.cnf. +
Generowane certyfikaty domylnie zabezpieczone s hasem, w takim przypadku +w momencie startu stunnela zawsze +
bdziesz pytany o haslo zabezpieczajce, co skutecznie uniemoliwi +automatyczne uruchamianie programu w czasie +
bootowania  serwera, czy te przy prbie wystartowania go przez +inetd. Naley poprawi linie 40 i 41 skryptu +

nsCertType = client, email  oraz "odhashowa" +linijk nsCertType   = server . Jeli tego +nie zrobisz klient nie bdzie +
poprawnie rozpoznawa typu certyfikatu. A teraz kolej na wygenerowanie +"requestu" posyanego zazwyczaj do CA. +

-----END RSA PRIVATE KEY----- + +

Spreparowany w ten sposb plik umieszczamy w katalogu /usr/local/ssl/certs +i zajmujemy si generowaniem dwu +
certyfikatw klienckich. +
  + +

Generowanie i importowanie certyfikatw klienckich +do Netscape Communikatora. +
  +
Generalnie s dwie metody tworzenia i importowania certyfikatw klienckich +do Netscapa +
Sposb pierwszy: +
Przy pomocy komendy CA.pl -newreq wygeneruj request a nastpnie +przy pomocy CA.pl -sign podpisz go. +
Pytanie o challenge password zignoruj. Kolejn czynnoci jest +scalenie i podczyszczenie certyfikatu. +
W przypadku certyfikatu klienta wane jest podanie prawidowego +adresu email ! Bez tego nie bdzie mona +
podpisywa i szyfrowa listw.  Stwrz dwa certyfikaty. Bd one +potrzebne do wyjanienia dziaania opcji -v 3 +
programu stunnel. Zakadam e pierwszy certyfikat naley do Jana Kowalskiego +jan@ibczim.pl zachowany w +
pliku jan.pem a drugi do Genowefy Pigwy pigwa@scyzoryki.pl znajdujcym +si w pliku pigwa.pem.  Przed +
zaimportowaniem plikw do Netscpea naley przekonwertowa je z formatu +PEM do PCKS12. Wykonuje si to +
przy pomocy wspomnianego na pocztku programu pcks12. Aby przekonwertowa +certyfikat Jan Kowalskiego, +
w katalogu w ktorym znajduje si plik jan.pem wykonaj: +
  + +

pkcs12 -export -name "Jan Kowalski jan@ibczim.pl" -in jan.pem -out +jan.p12 -certfile /usr/local/ssl/bin/demoCA/cacert.pem + +

(jest to jedna linia !!!) +
w wyniku czego powstanie plik jan.p12 ktry mona zaimportowa do Netscapea. +Bardzo wan opcj jest +
-certfile /usr/local/ssl/bin/demoCA/cacert.pem. Bez niej +nie bdzie mona w prawidowy sposb podpisywa listw. +
Przecznik -certfile powoduje doczenie publicznego certyfikatu CA +do certyfikatu klienta dziki czemu Netscape +
jest wstanie "wyekstrachowa" certyfikat CA i doda go do wewntrznej +bazy CA. Wykonaj powysz operacj take +
dla pigwy. Samo zaimportowanie certyfikatu jest bardzo proste wykonuje +si to klikajc w Netscape na + +

Security-> Yours -> Import a Certificate + +

Po zaimportowaniu naley w Security -> Signers zaznaczy nasz +CA certyfikat a nastpnie klikn na przycisku Edit +
oraz "zaczekowa" opcje: + +

Accept this Certificate Authority for Certifying network sites +
Accept this Certificate Authority for Certifying e-mail users + +

Od tej pory nasz certyfikat bdzie traktowany na rwni z innymi, komercyjnymi. + +

Sposb drugi: +
Polega on na wygenerowaniu i imporcie certyfikatu poprzez strone www. +Wraz z stunnelem dostarczane s +
przkadowe strony (dwie) i skrypty (dwa).  Skrypty naley raczej +traktowa jako wzorzec i kady powinien napisa +
swoje, bardziej bezpieczne. Pierwszym krokiem jest import certyfikatu +CA. Uywa si do tego strony importCA.html +
oraz skryptu importCA.sh. Sam skrypt wyglda tak: + +

#!/bin/bash + +

echo "Content-type: application/x-x509-ca-cert" +
echo +
cat /var/lib/httpds/cgi-bin/cacert.pem + +

cacert.pem jest to oczywicie certyfikat publiczny CA znajdujcy si +w katalogu /usr/local/ssl/bin/demoCA +
ktry naley przekopiowa do katalogu cgi-bin serwera httpd oraz nada +mu odpowiednie prawa dostpu. +
Po zaimportowaniu certyfikatu CA naley w Security->Signers zaznaczy +do jakich celw bdziemy uznawli +
go za wiarygodny. Do generowania certyfikatu klienta wykorzystamy pozosta +strone i skrypt. Zanim do tego dojdzie +
naley "dokonfigurowa" skrypt i stworzy potrzebne katalogi.  +W /tmp (lub w innym miejscu) nalezy stworzy +
katalog ssl a nastpnie przekopiowa do niego katalog /usr/local/bin/demoCA +oraz plik openssl.cnf. +
Jako e skrypty domylnie uruchamiane s z prawami uytkownika nobody +naley uczyni go  wlacicielem +
katalogu /tmp/ssl i caej jego zawartoci. Kolejn czynnoci jest +wygenerowanie pliku .rnd. W Linuxie robimy to +
tak: +

Po umieszczeniu tak przygotowanych stron i skryptw na serwerze bdzie +mona generowa certyfikaty dla klientw. + +

Wady i zalety obydwu sposobw generowania i instalowania certyfikatw. + +

Jak wynika z powyszego opisu bezpieczniejszym +i polecanym przeze mnie jest sposb pierwszy. Jego powan wad +
jest  fakt e czowiek generujcy certyfikaty znajduje si w posiadaniu +klucza prywatnego osoby wystpujcej o +
certyfikat.  Oczywicie uczciwy CA powinien +skasowa go, zaraz po utworzeniu. W takim wypadku metoda pierwsza +
spenia  wszelkie wymogi. Sposb drugi prcz samych wad ma jedn +acz ogromn zalet. Mianowicie klucz prywatny +
klienta  nigdy nie opuszcza jego komputera. Do wad mona zaliczy +fakt e haso zabezpieczajce klucz prywatny CA +
znajduje si na serwerze i to w dodatku w aden sposb nie chronione.  +Kolejn wad jest generowanie kompletnych +
certyfikatw przez strone www, co moe grozi wykradzeniem klucza prywatnego. +Rozwizaniem moe by skadowanie +
requestw w bazie danych a nastpnie rczna ich obrbka przez administratora. +Reasumujc, sposb drugi naley +

Tajemniczy przecznik -v 3 w stunnelu + +

Stunnel posiada trzy tryby weryfikacji klienta. +
Pierwszy opcja -v 1 oznacza e naley sprbowa +zweryfikowa osob nawizujc poczenie czyli uzyska jej +
ceryfikat. Jeli operacja ta si nie powiedzie, mimo wszystko dostp +do serwera bdzie zapewniony. +
Przecznik -v 2 nakazuje stunnelowi zweryfikowa +klienta. Jeli uytkownik nie posiada certyfikatu lub certyfikat +
jest niewany, niewaciwy czy te nie posiadamy certyfikatu CA ktrym +podpisany jest certyfikat klienta +
(straszny jest ten jzyk polski) nawizanie poczenia +z serwerem bdzie niemoliwe. I wreszcie opcja -v 3 +nakazujca +
stunnelowi zweryfikowa klienta a take poszuka jego certyfikatu w +naszej lokalnej bazie. +
Dzieki opcji -v 3 moemy stworzy bardzo selektywny dostp do usug +oferowanych przez serwer, unikajc generowania duych iloci certyfikatw. +Uwaga oglna: do poprawnej weryfikacji klienta KONIECZNE +jest posiadanie certyfikatu CA ktrym podpisany  jest sprawdzany certyfikat. +Bez tego stunnel nie jest wstanie przeprowadzi poprawnej autoryzacji klienta. +Prba taka koczy si bdami "VERIFY ERROR: self signed certificate +for ....." oraz "SSL_accept: error:140890B1:SSL routines: SSL3_GET_CLIENT_CERTIFICATE:no +certificate returned". A teraz przykad praktyczny: chcemy aby do https +bdcym na porcie 444 miay dostp wszystkie osoby majce certyfikaty +natomiast +
do do https na porcie 445 dostp mia tylko Jan Kowalski. Pierwsz +czynnoci jak naley wykona jest skopiowanie +
certyfikatu CA do katalogu /usr/local/ssl/certs (default cert +area), nastpnie w tym katalogu naley utworzy +
podkatalog o  nazwie mytrusted, poczym skopiowa do niego +certyfikat klienta czyli jan.pem. Uwaga: z pliku +jan.pem +

Teraz kolej na uruchomienie stunnela: +

DESCRIPTION

+

Le programme stunnel est conçu pour fonctionner comme une couche +de chiffrement SSL entre des clients distants et des serveurs locaux +(inetd-démarrables) ou distants. Le concept est qu'à partir de daemons +non-SSL présents sur le système, on peut facilement les configurer pour +communiquer avec des clients sur des liens sécurisés SSL.

+

stunnel peut être utilisé pour ajouter des fonctionnalités SSL à des +daemons classiques Inetd tels que les serveurs POP-2, POP-3 et IMAP, +à d'autres autonomes tels que NNTP, SMTP et HTTP, ainsi que pour tunneliser +PPP sur des sockets réseau sans modification du code source.

+

Ce produit inclut du code de chiffrement écrit par +Eric Young (eay@cryptsoft.com)

+

+

Chaque ligne du fichier de configuration peut être soit :

+
    +
  • +

    une ligne vide (ignorée) ;

    +
    • +
  • +

    un commentaire commençant par « # » (ignoré) ;

    +
    • +
  • +

    une paire « option = valeur » ;

    +
    • +
  • +

    « [service_name] » indiquant le début de la définition d'un service ;

    +
    • +
+

+

+

OPTIONS GLOBALES

+
+
CApath = répertoire
+ +
+

Répertoire des autorités de certification (CA)

+

C'est le répertoire dans lequel stunnel cherche les certificats si +l'on utilise verify. Les certificats doivent être dénommés selon la +forme XXXXXXXX.0, où XXXXXXXX est la valeur de hachage du certificat.

+

Le cas échéant, le répertoire CApath est relatif au répertoire chroot.

+
+
CAfile = fichier
+ +
+

Fichier d'autorités de certification

+

Ce fichier, utilisé avec verify, contient plusieurs certificats de CA.

+
+
cert = fichier
+ +
+

Fichier de chaîne de certificats PEM

+

Une PEM est toujours nécessaire en mode serveur. +En mode client, cette option utilise cette PEM comme une chaîne côté client. +L'utilisation de certificats côté client est optionnelle. Les certificats +doivent être au format PEM et triés par ordre de niveau décroissant (CA racine +en premier).

+
+
chroot = répertoire (Unix seulement)
+ +
+

Répertoire de chroot du processus stunnel

+

chroot enferme stunnel dans une cellule chroot. CApath, CRLpath, pid +et exec sont situés à l'intérieur de la cellule et les répertoires doivent être +relatifs au répertoire correspondant.

+

Pour que le contrôle de libwrap (wrappeur TCP) soit effectif dans un environnement +chroot, il faut aussi y recopier leurs fichiers de configuration (/etc/hosts.allow et +/etc/hosts.deny).

+
+
ciphers = listes de chiffre
+ +
+

Sélection des chiffres SSL autorisés

+

Liste délimitée par deux-points (« : ») des chiffres autorisés pour la connexion SSL. +Exemple : DES-CBC3-SHA:IDEA-CBC-MD5

+
+
client = yes | no
+ +
+

Mode client (Le service distant utilise SSL)

+

Par défaut : no (mode server)

+
+
CRLpath = répertoire
+ +
+

Répertoire des listes de révocation de certificats (CRL)

+

C'est le répertoire dans lequel stunnel recherche les CRL avec +l'option verify. Les CRL doivent être dénommés selon la +forme XXXXXXXX.0 où XXXXXXXX est la valeur de hachage de la CRL.

+

Le cas échéant, le répertoire CRLpath est relatif au répertoire chroot.

+
+
CRLfile = fichier
+ +
+

Fichier de listes de révocation de certificats (CRL)

+

Ce fichier, utilisé avec verify, contient plusieurs CRL.

+
+
debug = [facilité.]niveau
+ +
+

niveau de déverminage

+

Le niveau est un nom ou un numéro conforme à ceux de syslog : +emerg (0), alert (1), crit (2), err (3), warning (4), notice (5), +info (6) ou debug (7). Toutes les traces du niveau indiqué et des niveaux +numériquement inférieurs seront affichées. debug = debug ou +debug = 7 donneront le maximum d'informations. La valeur par défaut +est notice (5).

+

La facilité syslog « daemon » est utilisée, sauf si un autre nom est spécifié +(Win32 ne permet pas l'usage des facilités.)

+

La casse est ignorée, aussi bien pour la facilité que pour le niveau.

+
+
EGD = chemin (Unix seulement)
+ +
+

Emplacement du socket du daemon de recueil d'entropie (EGD - Entropy Gathering Daemon)

+

Socket EGD à utiliser pour alimenter le générateur d'aléatoires de OpenSSL (disponible +seulement si la compilation a été effectuée avec OpenSSL 0.9.5a ou supérieur).

+
+
foreground = yes | no (Unix seulement)
+ +
+

Mode avant-plan

+

Reste en avant-plan (sans fork) et dirige la trace sur stderr +au lieu de syslog (sauf si output est spécifié).

+

Par défault : arrière-plan en mode daemon.

+
+
key = fichier
+ +
+

Fichier de clef privée pour le certificat spécifié par cert

+

La clef privée est nécessaire pour authentifier le titulaire du +certificat. +Puisque ce fichier doit rester secret, il ne doit être lisible que +par son propriétaire. Sur les systèmes Unix, on peut utiliser la +commande suivante :

+
+    chmod 600 fichier
+

Par défault : Valeur de cert

+
+
options = Options_SSL
+ +
+

Options de la bibliothèque OpenSSL

+

Le paramètre est l'option OpenSSL décrite dans la page de man +SSL_CTX_set_options(3ssl), débarassée du préfixe SSL_OP_. +Plusieurs options peuvent être spécifiées.

+

Par exemple, pour la compatibilité avec l'implantation SSL défaillante +d'Eudora, on peut utiliser :

+
+    options = DONT_INSERT_EMPTY_FRAGMENTS
+
+
output = fichier
+ +
+

Ajoute la trace à la fin d'un fichier au lieu d'utiliser syslog.

+

/dev/stdout peut être utilisé pour afficher les traces sur la sortie standard +(par exemple pour les traiter avec les outils splogger).

+
+
pid = fichier (Unix seulement)
+ +
+

Emplacement du fichier pid

+

Si l'argument est vide, aucun fichier ne sera créé.

+

Le cas échéant, le chemin pid est relatif au répertoire chroot.

+
+
RNDbytes = nombre
+ +
+

Nombre d'octets à lire depuis les fichiers de « sel » aléatoire

+

Avec les SSL de version inférieure à 0.9.5a, détermine aussi le nombre +d'octets considérés comme suffisants pour « saler » le PRNG. Les versions plus +récentes d'OpenSSL ont une fonction intégrée qui détermine lorsque l'aléatoire +est suffisant.

+
+
RNDfile = fichier
+ +
+

chemin du fichier de données de « sel » aléatoire

+

La bibliothèque SSL utilise prioritairement les données de ce fichier pour +« saler » le générateur d'aléatoire.

+
+
RNDoverwrite = yes | no
+ +
+

Recouvre les fichiers de « sel » avec de nouvelles données aléatoires.

+

Par défaut : yes

+
+
service = nom
+ +
+

Définit le nom de service à utiliser

+

Sous Unix : nom de service du mode inetd pour la bibliothèque TCP Wrapper.

+

Par défaut : stunnel

+
+
session = timeout
+ +
+

Timeout du cache de session

+
+
setgid = nom (Unix seulement)
+ +
+

Nom de groupe utilisé en mode daemon (les éventuels autres noms de groupe attribués sont supprimés)

+
+
setuid = nom (Unix seulement)
+ +
+

Nom d'utilisateur utilisé en mode daemon

+
+
socket = a|l|r:option=valeur[:valeur]
+ +
+

Configure une option de socket accept (a), locale (l) ou distante (r)

+

Les valeurs de l'option linger sont : l_onof:l_linger. +Les valeurs de l'option time sont : tv_sec:tv_usec.

+

Exemples :

+
+    socket = l:SO_LINGER=1:60
+        définit un délai d'une minute pour la clôture des sockets locaux
+    socket = r:SO_OOBINLINE=yes
+        Place directement les données hors-bande dans le flux de réception
+        des sockets distants
+    socket = a:SO_REUSEADDR=no
+        désactive la réutilisation d'adresses (activée par défaut)
+    socket = a:SO_BINDTODEVICE=lo
+        limite l'acceptation des connexions sur la seule interface de bouclage
+
+
taskbar = yes | no (WIN32 seulement)
+ +
+

active l'icône de la barre de tâches

+

Par défaut : yes

+
+
verify = niveau
+ +
+

Vérifie le certificat du correspondant

+
+    niveau 1 - vérifie le certificat s'il est présent
+    niveau 2 - vérifie le certificat
+    niveau 3 - contrôle le correspondant avec le certificat local
+

Par défaut - pas de vérification

+
+
+

+

+

OPTIONS DE SERVICE

+

Chaque section de configuration commence par le nom du service entre crochets. +Celui-ci est utilisé par le contrôle d'accès de libwrap (TCP Wrappers) et sert +à distinguer les services stunnel dans les fichiers de traces.

+

Si l'on souhaite utiliser stunnel en mode inetd (lorsqu'un socket lui est +fourni par un serveur comme inetd, xinetd ou tcpserver), il faut se +reporter à la section MODE INETD plus bas.

+
+
accept = [hôte:]port
+ +
+

Accepte des connexions sur le port spécifié

+

Si l'hôte n'est pas indiqué, le port est ouvert pour toutes les adresses IP de +la machine locale.

+
+
connect = [hôte:]port
+ +
+

Se connecte au port distant indiqué

+

Par défaut, l'hôte est localhost.

+
+
delay = yes | no
+ +
+

Retarde la recherche DNS pour l'option « connect »

+
+
exec = chemin_exécutable (Unix seulement)
+ +
+

Exécute un programme local de type inetd

+

Le cas échéant, le chemin exec est relatif au répertoire chroot.

+
+
execargs = $0 $1 $2 ... (Unix seulement)
+ +
+

Arguments pour exec, y compris le nom du programme ($0)

+

Les quotes ne peuvent actuellement pas être utilisées. +Les arguments sont séparés par un nombre quelconque d'espaces.

+
+
ident = nom
+ +
+

Applique le contrôle d'identité d'utilisateur IDENT (RFC 1413)

+
+
local = hôte
+ +
+

Adresse IP de l'interface de sortie utilisée pour les connexions distantes. +Cette option permet de relier une adresse statique locale.

+
+
protocol = protocole
+ +
+

Négocie avec SSL selon le protocole indiqué

+

Actuellement gérés : cifs, nntp, pop3, smtp

+
+
pty = yes | no (Unix seulement)
+ +
+

Alloue un pseudo-terminal pour l'option « exec »

+
+
TIMEOUTbusy = secondes
+ +
+

Durée d'attente de données

+
+
TIMEOUTclose = secondes
+ +
+

Durée d'attente du close_notify (mis à 0 pour MSIE qui est bogué)

+
+
TIMEOUTidle = secondes
+ +
+

Durée d'attente sur une connexion inactive

+
+
transparent = yes | no (Unix seulement)
+ +
+

Mode mandataire transparent

+

Ré-écrit les adresses pour qu'elles apparaissent provenir de la +machine client SSL plutôt que de celle qui exécute stunnel. +Cette option n'est disponible en mode local (option exec) qu'avec +la bibliothèque partagée LD_PRELOADing env.so shared library et en mode +distant (option connect) sur les noyaux Linux 2.2 compilés avec +l'option transparent proxy et seulement en mode serveur. Cette +option ne se combine pas au mode mandataire (connect) sauf si la +route par défaut du client vers la cible passe par l'hôte qui fait +tourner stunnel, qui ne peut être localhost.

+
+
+

+

+
+

VALEUR DE RETOUR

+

stunnel renvoie zéro en cas de succès, une autre valeur en cas d'erreur.

+

+

+
+

EXEMPLES

+

Pour encapsuler votre service imapd local avec SSL :

+
+    [imapd]
+    accept = 993
+    exec = /usr/sbin/imapd
+    execargs = imapd
+

Pour tunneliser un daemon pppd sur le port 2020 :

+
+    [vpn]
+    accept = 2020
+    exec = /usr/sbin/pppd
+    execargs = pppd local
+    pty = yes
+

Configuration de stunnel.conf pour utiliser stunnel en mode inetd +qui lance imapd à son tour (il ne doit pas y avoir de section [service_name]) :

+
+    exec = /usr/sbin/imapd
+    execargs = imapd
+

+

BOGUES

+

L'option execargs n'admet pas les quotes.

+

+

+
+

RESTRICTIONS

+

stunnel ne peut être utilisé pour le daemon FTP en raison de la nature +du protocole FTP qui utilise des ports multiples pour les transferts de données. +Il existe cependant des versions SSL de FTP et de telnet.

+

+

+
+

NOTES

+

+

+

MODE INETD

+

L'utilisation la plus commune de stunnel consiste à écouter un port +réseau et à établir une communication, soit avec un nouveau port +avec l'option connect, soit avec un programme avec l'option exec. +On peut parfois cependant souhaiter qu'un autre programme reçoive les +connexions entrantes et lance stunnel, par exemple avec inetd, +xinetd ou tcpserver.

+

Si, par exemple, la ligne suivante se trouve dans inetd.conf :

+
+    imaps stream tcp nowait root /usr/bin/stunnel stunnel /etc/stunnel/imaps.conf
+

Dans ces cas, c'est le programme du genre inetd-style qui est +responsable de l'établissement de la connexion (imaps ci-dessus) et de passer +celle-ci à stunnel. +Ainsi, stunnel ne doit alors avoir aucune option accept. +Toutes les options de niveau service doivent être placées dans +la section des options globales et aucune section [service_name] ne doit +être présente. Voir la section EXEMPLES pour des exemples de configurations.

+

+

+

CERTIFICATS

+

Chaque daemon à propriétés SSL doit présenter un certificat X.509 +valide à son interlocuteur. Il a aussi besoin d'une clef privé pour +déchiffrer les données entrantes. La méthode la plus simple pour +obtenir un certificat et une clef est d'engendrer celles-ci avec +le paquetage libre OpenSSL. Plus d'informations sur la génération de +certificats se trouvent dans les pages indiquées plus bas.

+

Deux choses importantes lors de la génération de paires certificat-clef +pour stunnel :

+
    +
  • +

    la clef privée ne peut être chiffrée puisque le serveur n'a aucun moyen +d'obtenir le mot de passe de l'utilisateur ; pour produire une clef non chiffrée, +ajouter l'option -nodes à la commande req de OpenSSL ;

    +
    • +
  • +

    l'ordre du contenu du fichier .pem est significatif : il doit contenir d'abord +une clef privée non chiffrée, puis un certificat signé (et non une demande de certificat). +Il doit aussi y avoir des lignes vides après le certificat et après la clef privée. +L'information textuelle ajoutée au début d'un certificat doit être supprimée afin que +le fichier ait l'allure suivante :

    +
    +    -----BEGIN RSA PRIVATE KEY-----
+    [clef encodée]
+    -----END RSA PRIVATE KEY-----
+    [ligne vide]
+    -----BEGIN CERTIFICATE-----
+    [certificat encodé]
+    -----END CERTIFICATE-----
+    [ligne vide]
    +
    • +
+

+

+

ALEATOIRE

+

stunnel doit « saler » le générateur de pseudo-aléatoires PRNG (pseudo random +number generator) afin que SSL utilise un aléatoire de qualité. Les sources suivantes +sont chargées dans l'ordre jusqu'à ce qu'une quantité suffisante de données soit lue :

+
    +
  • +

    le fichier spécifié par RNDfile ;

    +
    • +
  • +

    le fichier spécifié par la variable d'environnement RANDFILE, à défaut +le fichier .rnd du répertoire $HOME de l'utilisateur ;

    +
    • +
  • +

    le fichier spécifié par « --with-random » lors de la compilation ;

    +
    • +
  • +

    le contenu de l'écran (MS-Windows seulement) ;

    +
    • +
  • +

    le socket EGD spécifié par EGD ;

    +
    • +
  • +

    le socket EGD spécifié par « --with-egd-sock » lors de la compilation ;

    +
    • +
  • +

    le périphérique /dev/urandom.

    +
    • +
+

Avec un OpenSSL récent (>=OpenSSL 0.9.5a) le chargement de données s'arrête +automatiquement lorsqu'un niveau d'entropie suffisant est atteint. +Les versions précédentes continuent à lire toutes les sources puisqu'aucune +fonction SSL ne leur permet de savoir que suffisamment de données sont disponibles.

+

Sur les machines MS-Windows qui n'ont pas d'interaction utilisateur sur la console, +(mouvements de souris, création de fenêtres, etc.), le contenu de l'écran n'est +pas suffisamment changeant et il est nécessaire de fournir un fichier d'aléatoire +par le biais de RNDfile.

+

Le fichier spécifié par RNDfile doit contenir des informations aléatoires -- +c'est-à-dire des informations différentes à chaque lancement de stunnel. +Cela est géré automatiquement sauf si l'option RNDoverwrite est utilisée. +Si l'on souhaite procéder manuellement à la mise à jour de ce fichier, la +commande openssl rand des versions récentes d'OpenSSL sera sans doute utile.

+

Note importante : si /dev/urandom est disponible, OpenSSL a l'habitude d'utiliser +celui-ci pour « saler » le PRNG même lorsqu'il contrôle l'état de l'aléatoire ; +ainsi, même si /dev/urandom est dernier de la liste ci-dessus, il est vraisemblable +qu'il soit utilisé s'il est présent. +Ce n'est pas le comportement de stunnel, c'est celui d'OpenSSL.

SYNOPSIS

+
+
Unix:
+ +
+

stunnel [<filename>] | -fd n | -help | -version | -sockets

+
+
WIN32:

+
+

DESCRIPTION

+

The stunnel program is designed to work as SSL encryption wrapper +between remote clients and local (inetd-startable) or remote +servers. The concept is that having non-SSL aware daemons running on +your system you can easily set them up to communicate with clients over +secure SSL channels.

+

stunnel can be used to add SSL functionality to commonly used Inetd +daemons like POP-2, POP-3, and IMAP servers, to standalone daemons like +NNTP, SMTP and HTTP, and in tunneling PPP over network sockets without +changes to the source code.

+

This product includes cryptographic software written by +Eric Young (eay@cryptsoft.com)

An address parameter of an option may be either:

+ +

+

+

GLOBAL OPTIONS

+
+
chroot = directory (Unix only)
+ +
+

directory to chroot stunnel process

+

chroot keeps stunnel in chrooted jail. CApath, CRLpath, pid +and exec are located inside the jail and the patches have to be relative +to the directory specified with chroot.

+
+
compression = deflate | zlib | rle
+ +
+

select data compression algorithm

+

default: no compression

+

deflate is the standard compression method as described in RFC 1951.

+

zlib compression of OpenSSL 0.9.8 or above is not backward compatible with +OpenSSL 0.9.7.

+

rle compression is currently not implemented by the OpenSSL library.

+
+
debug = [facility.]level
+ +
+

debugging level

+

Level is a one of the syslog level names or numbers +emerg (0), alert (1), crit (2), err (3), warning (4), notice (5), +info (6), or debug (7). All logs for the specified level and +all levels numerically less than it will be shown. Use debug = debug or +debug = 7 for greatest debugging output. The default is notice (5).

+

The syslog facility 'daemon' will be used unless a facility name is supplied. +(Facilities are not supported on Win32.)

+

Case is ignored for both facilities and levels.

+
+
EGD = egd path (Unix only)
+ +
+

path to Entropy Gathering Daemon socket

This option allows to disable entering FIPS mode if stunnel was compiled with +FIPS 140-2 support.

+

default: yes

+
+
foreground = yes | no (Unix only)
+ +
+

foreground mode

+

Stay in foreground (don't fork) and log to stderr +instead of via syslog (unless output is specified).

+

default: background in daemon mode

+
+
output = file
+ +
+

pid file location

+

If the argument is empty, then no pid file will be created.

+

pid path is relative to chroot directory if specified.

+
+
RNDbytes = bytes
+ +
+

bytes to read from random seed files

+

Number of bytes of data read from random seed files. With SSL versions +less than 0.9.5a, also determines how many bytes of data are considered +sufficient to seed the PRNG. More recent OpenSSL versions have a builtin +function to determine when sufficient randomness is available.

+
+
RNDfile = file
+ +
+

path to file with random seed data

+

The SSL library will use data from this file first to seed the random +number generator.

+
+
RNDoverwrite = yes | no
+ +
+

+

default: yes

+
+
+

+

+

SERVICE-LEVEL OPTIONS

+

Each configuration section begins with service name in square brackets. +The service name is used for libwrap (TCP Wrappers) access control and lets +you distinguish stunnel services in your log files.

+

Note that if you wish to run stunnel in inetd mode (where it +is provided a network socket by a server such as inetd, xinetd, +or tcpserver) then you should read the section entitled INETD MODE +below.

+
+
accept = address
+ +
+

accept connections on specified address

+

If no host specified, defaults to all IPv4 addresses for the local host.

+

To listen on all IPv6 addresses use:

+
+    connect = :::port
+
+
CApath = directory
+ +
+

Certificate Authority directory

+

This is the directory in which stunnel will look for certificates when using +the verify. Note that the certificates in this directory should be named +XXXXXXXX.0 where XXXXXXXX is the hash value of the DER encoded subject of the +cert.

+

The hash algorithm has been changed in OpenSSL 1.0.0. It is required to +c_rehash the directory on upgrade from OpenSSL 0.x.x to OpenSSL 1.x.x.

+

CApath path is relative to chroot directory if specified.

+
+
CAfile = certfile
+ +
+

Certificate Authority file

+

This file contains multiple CA certificates, used with the verify.

+
+
cert = pemfile
+ +
+

certificate chain PEM file name

+

A PEM is always needed in server mode. +Specifying this flag in client mode will use this certificate chain +as a client side certificate chain. Using client side certs is optional. +The certificates must be in PEM format and must be sorted starting with the +certificate to the highest level (root CA).

+
+
ciphers = cipherlist
+ +
+

Select permitted SSL ciphers

+

A colon delimited list of the ciphers to allow in the SSL connection. +For example DES-CBC3-SHA:IDEA-CBC-MD5

+
+
client = yes | no
+ +
+

client mode (remote service uses SSL)

+

default: no (server mode)

+
+
connect = address
+ +
+

connect to a remote address

+

If no host is specified, the host defaults to localhost.

+

Multiple connect options are allowed in a single service section.

+

If host resolves to multiple addresses and/or if multiple connect +options are specified, then the remote address is chosen using a +round-robin algorithm.

+
+
CRLpath = directory
+ +
+

Certificate Revocation Lists directory

+

This is the directory in which stunnel will look for CRLs when +using the verify. Note that the CRLs in this directory should +be named XXXXXXXX.r0 where XXXXXXXX is the hash value of the CRL.

+

The hash algorithm has been changed in OpenSSL 1.0.0. It is required to +c_rehash the directory on upgrade from OpenSSL 0.x.x to OpenSSL 1.x.x.

+

CRLpath path is relative to chroot directory if specified.

+
+
CRLfile = certfile
+ +
+

Certificate Revocation Lists file

+

This file contains multiple CRLs, used with the verify.

+
+
curve = nid
+ +
+

specify ECDH curve name

+

To get a list of supported cuves use:

+
+    openssl ecparam -list_curves
+

default: prime256v1

+
+
delay = yes | no
+ +
+

delay DNS lookup for 'connect' option

+

This option is useful for dynamic DNS, or when DNS is not available during +stunnel startup (road warrior VPN, dial-up configurations).

+
+
engineNum = engine number
+ +
+

select engine number to read private key

+

The engines are numbered starting from 1.

+
+
exec = executable_path
+ +
+

execute local inetd-type program

+

exec path is relative to chroot directory if specified.

+
+
execargs = $0 $1 $2 ...
+ +
+

arguments for exec including program name ($0)

+

Quoting is currently not supported. +Arguments are separated with arbitrary number of whitespaces.

+
+
failover = rr | prio
+ +
+

Failover strategy for multiple "connect" targets.

+
+    rr (round robin) - fair load distribution
+    prio (priority) - use the order specified in config file
+

default: rr

+
+
ident = username
+ +
+

use IDENT (RFC 1413) username checking

+
+
key = keyfile
+ +
+

private key for certificate specified with cert option

+

Private key is needed to authenticate certificate owner. +Since this file should be kept secret it should only be readable +to its owner. On Unix systems you can use the following command:

+
+    chmod 600 keyfile
+

default: value of cert option

+
+
libwrap = yes | no
+ +
+

Enable or disable the use of /etc/hosts.allow and /etc/hosts.deny.

+

default: yes

+
+
local = host
+ +
+

IP of the outgoing interface is used as source for remote connections. +Use this option to bind a static local IP address, instead.

+
+
sni = service_name:server_name (server mode)
+ +
+

Use the service as a slave service (a name-based virtual server) for Server +Name Indication TLS extension (RFC 3546).

+

service_name specifies the master service that accepts client connections +with accept option. server_name specifies the host name to be redirected. +Multiple slave services are normally specified for a single master service. +sni option can also be specified more than once within a single slave service.

+

This service, as well as the master service, may not be configured in client mode. +connect option of the slave service is ignored when protocol option is +specified, as protocol connects remote host before TLS handshake. +Libwrap checks (Unix only) are performed twice: with master service name after +TCP connection is accepted, and with slave service name during TLS handshake.

+

Option sni is only available when compiled with OpenSSL 1.0.0 and later.

+
+
sni = server_name (client mode)
+ +
+

Use the parameter as the value of TLS Server Name Indication (RFC 3546) +extension.

+

Option sni is only available when compiled with OpenSSL 1.0.0 and later.

+
+
OCSP = url
+ +
+

select OCSP server for certificate verification

+
+
OCSPflag = flag
+ +
+

Several OCSPflag can be used to specify multiple flags.

+

currently supported flags: NOCERTS, NOINTERN NOSIGS, NOCHAIN, NOVERIFY, +NOEXPLICIT, NOCASIGN, NODELEGATED, NOCHECKS, TRUSTOTHER, RESPID_KEY, NOTIME

+
+
options = SSL_options
+ +
+

OpenSSL library options

+

The parameter is the OpenSSL option name as described in the +SSL_CTX_set_options(3ssl) manual, but without SSL_OP_ prefix. +Several options can be used to specify multiple options.

+

For example for compatibility with erroneous Eudora SSL implementation +the following option can be used:

+
+    options = DONT_INSERT_EMPTY_FRAGMENTS
+
+
protocol = proto
+ +
+

application protocol to negotiate SSL (e.g. starttls or stls)

+

protocol option should not be used with SSL encryption on a separate port.

+

Currently supported protocols:

+

+
+
+
+
protocolAuthentication = auth_type
+ +
+

+

Currently authentication type only applies to 'connect' protocol.

+

default: basic

+
+

+ +
+

Disable transparent proxy support. This is the default.

+
+
source
+ +
+

Re-write address to appear as if wrapped daemon is connecting +from the SSL client machine instead of the machine running stunnel.

+

This option is currently available in:

+
+
Remote mode (connect option) on Linux >=2.6.28
+ +
+

This configuration requires stunnel to be executed as root and without +setuid option.

+

This configuration requires the following setup for iptables and routing +(possibly in /etc/rc.local or equivalent file):

+
+    iptables -t mangle -N DIVERT
+    iptables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT
+    iptables -t mangle -A DIVERT -j MARK --set-mark 1
+    iptables -t mangle -A DIVERT -j ACCEPT
+    ip rule add fwmark 1 lookup 100
+    ip route add local 0.0.0.0/0 dev lo table 100
+    echo 0 >/proc/sys/net/ipv4/conf/lo/rp_filter
+

stunnel must also to be executed as root and without setuid option.

+
+
Remote mode (connect option) on Linux 2.2.x
+ +
+

This configuration requires kernel to be compiled with transparent proxy option. +Connected service must be installed on a separate host. +Routing towards the clients has to go through the stunnel box.

+

stunnel must also to be executed as root and without setuid option.

+
+
Remote mode (connect option) on FreeBSD >=8.0
+ +
+

This configuration requires additional firewall and routing setup. +stunnel must also to be executed as root and without setuid option.

+
+
Local mode (exec option)
+ +
+

This configuration works by pre-loading libstunnel.so shared library. +_RLD_LIST environment variable is used on Tru64, and LD_PRELOAD variable on +other platforms.

+
+
+
+
destination
+ +
+

Original destination is used instead of connect option.

+

A service section for transparent destination may look like this:

+
+    [transparent]
+    client=yes
+    accept=<stunnel_port>
+    transparent=destination
+

This configuration requires the following setup for iptables +(possibly in /etc/rc.local or equivalent file):

+
+    /sbin/iptables -I INPUT -i eth0 -p tcp --dport <stunnel_port> -j ACCEPT
+    /sbin/iptables -t nat -I PREROUTING -i eth0 -p tcp --dport <redirected_port> -j DNAT --to-destination <local_ip>:<stunnel_port>
+

Transparent destination option is currently only supported on Linux.

+
+
both
+ +
+

Use both source and destination transparent proxy.

+
+
+

Two legacy options are also supported for backward compatibility:

+
+
yes
+ +
+

This options has been renamed to source.

+
+
no
+ +
+

This options has been renamed to none.

+
+
+
+
verify = level
+ +
+

verify peer certificate

+
+
level 0 - request and ignore peer certificate
+ +
level 1 - verify peer certificate if present
+ +
level 2 - verify peer certificate
+ +
level 3 - verify peer with locally installed certificate
+ +
level 4 - ignore CA chain and only verify peer certificate
+ +
default - no verify
+ +
+

It is important to understand, that this option was solely designed for access +control and not for authorization. Specifically for level 2 every non-revoked +certificate is accepted regardless of its Common Name. For this reason a +dedicated CA should be used with level 2, and not a generic CA commonly used +for webservers. Level 3 is preferred for point-to-point connections.

+
+
+

+

+
+

RETURN VALUE

+

stunnel returns zero on success, non-zero on error.

+

+

+
+

SIGNALS

+

The following signals can be used to control stunnel in Unix environment:

+
+
SIGHUP
+ +
+

Force a reload of the configuration file.

+

Some global options will not be reloaded:

+ +

The use of 'setuid' option will also prevent stunnel from binding privileged +(<1024) ports during configuration reloading.

+

When 'chroot' option is used, stunnel will look for all its files (including +configuration file, certificates, log file and pid file) within the chroot +jail.

+
+
SIGUSR1
+ +
+

Close and reopen stunnel log file. +This function can be used for log rotation.

+
+
SIGTERM, SIGQUIT, SIGINT
+ +
+

Shut stunnel down.

+
+
+

The result of sending any other signals to the server is undefined.

+

+

+
+

EXAMPLES

+

In order to provide SSL encapsulation to your local imapd service, use

+
+    [imapd]
+    accept = 993
+    exec = /usr/sbin/imapd
+    execargs = imapd
+

If you want to provide tunneling to your pppd daemon on port 2020, +use something like

+
+    [vpn]
+    accept = 2020
+    exec = /usr/sbin/pppd
+    execargs = pppd local
+    pty = yes
+

If you want to use stunnel in inetd mode to launch your imapd +process, you'd use this stunnel.conf. +Note there must be no [service_name] section.

+
+    exec = /usr/sbin/imapd
+    execargs = imapd
+

+

+
+

NOTES

+

+

+

RESTRICTIONS

+

stunnel cannot be used for the FTP daemon because of the nature +of the FTP protocol which utilizes multiple ports for data transfers. +There are available SSL enabled versions of FTP and telnet daemons, however.

+

+

+

INETD MODE

+

The most common use of stunnel is to listen on a network +port and establish communication with either a new port +via the connect option, or a new program via the exec option. +However there is a special case when you wish to have +some other program accept incoming connections and +launch stunnel, for example with inetd, xinetd, +or tcpserver.

+

For example, if you have the following line in inetd.conf:

+
+    imaps stream tcp nowait root /usr/bin/stunnel stunnel /etc/stunnel/imaps.conf
+

In these cases, the inetd-style program is responsible +for binding a network socket (imaps above) and handing +it to stunnel when a connection is received. +Thus you do not want stunnel to have any accept option. +All the Service Level Options should be placed in the +global options section, and no [service_name] section +will be present. See the EXAMPLES section for example +configurations.

+

+

+

CERTIFICATES

+

Each SSL enabled daemon needs to present a valid X.509 certificate +to the peer. It also needs a private key to decrypt the incoming +data. The easiest way to obtain a certificate and a key is to +generate them with the free OpenSSL package. You can find more +information on certificates generation on pages listed below.

+

The order of contents of the .pem file is important. It should contain the +unencrypted private key first, then a signed certificate (not certificate +request). There should be also empty lines after certificate and private key. +Plaintext certificate information appended on the top of generated certificate +should be discarded. So the file should look like this:

+
+    -----BEGIN RSA PRIVATE KEY-----
+    [encoded key]
+    -----END RSA PRIVATE KEY-----
+    [empty line]
+    -----BEGIN CERTIFICATE-----
+    [encoded certificate]
+    -----END CERTIFICATE-----
+    [empty line]
+

+

+

RANDOMNESS

+

stunnel needs to seed the PRNG (pseudo random number generator) in +order for SSL to use good randomness. The following sources are loaded +in order until sufficient random data has been gathered:

+ +

With recent (>=OpenSSL 0.9.5a) version of SSL it will stop loading +random data automatically when sufficient entropy has been gathered. +With previous versions it will continue to gather from all the above +sources since no SSL function exists to tell when enough data is available.

+

Note that on Windows machines that do not have console user interaction +(mouse movements, creating windows, etc.) the screen contents are not +variable enough to be sufficient, and you should provide a random file +for use with the RNDfile flag.

+

Note that the file specified with the RNDfile flag should contain +random data -- that means it should contain different information +each time stunnel is run. This is handled automatically +unless the RNDoverwrite flag is used. If you wish to update this file +manually, the openssl rand command in recent versions of OpenSSL, +would be useful.

+

One important note -- if /dev/urandom is available, OpenSSL has a habit of +seeding the PRNG with it even when checking the random state, so on +systems with /dev/urandom you're likely to use it even though it's listed +at the very bottom of the list above. This isn't stunnel's behaviour, it's +OpenSSLs.

+

+

+

DH PARAMETERS

+

Stunnel 4.40 and later contains hardcoded 2048-bit DH parameters.

+

It is also possible to specify DH parameters in the certificate file:

+
+    openssl dhparam 2048 >> stunnel.pem
+

DH parameter generation may take several minutes.

+

OPIS

+

Program stunnel został zaprojektowany do opakowywania w protokół SSL +połączeń pomiędzy zdalnymi klientami a lokalnymi lub zdalnymi serwerami. +Przez serwer lokalny rozumiana jest aplikacja przeznaczona do uruchamiania +przy pomocy inetd. +Stunnel pozwala na proste zestawienie komunikacji serwerów nie posiadających +funkcjonalności SSL poprzez bezpieczne kanały SSL.

+

stunnel pozwala dodać funkcjonalność SSL do powszechnie stosowanych +demonów inetd, np. pop3 lub imap, do samodzielnych demonów, +np. nntp, smtp lub http, a nawet tunelować ppp poprzez gniazda sieciowe +bez zmian w kodzie źródłowym.

+

+

+ +

Parametr adres może być:

+ +

+

+

OPCJE GLOBALNE

+
+
chroot = katalog (tylko Unix)
+ +
+

katalog roboczego korzenia systemu plików

+

Opcja określa katalog, w którym uwięziony zostanie proces programu +stunnel tuż po jego inicjalizacji, a przed rozpoczęciem odbierania +połączeń. Ścieżki podane w opcjach CApath, CRLpath, pid +oraz exec muszą być umieszczone wewnątrz katalogu podanego w opcji +chroot i określone względem tego katalogu.

+
+
compression = deflate | zlib | rle
+ +
+

wybór algorytmu kompresji przesyłanych danych

+

domyślnie: bez kompresji

+

Algorytm deflate jest standardową metodą kompresji zgodnie z RFC 1951.

+

Kompresja zlib zaimplementowana w OpenSSL 0.9.8 i nowszych nie jest +kompatybilna implementacją OpenSSL 0.9.7.

+

Kompresja rle nie jest zaimplementowana w aktualnych wersjach OpenSSL.

+
+
debug = poziom[.podsystem]
+ +
+

szczegółowość logowania

+

Poziom logowania można określić przy pomocy jednej z nazw lub liczb: +emerg (0), alert (1), crit (2), err (3), warning (4), notice (5), +info (6) lub debug (7). +Zapisywane są komunikaty o poziomie niższym (numerycznie) lub równym podanemu. +Do uzyskania najwyższego poziomu szczegółowości można użyć opcji +debug = debug lub debug = 7. Domyślnym poziomem jest notice (5).

+

O ile nie wyspecyfikowano podsystemu użyty będzie domyślny: daemon. +Podsystemy nie są wspierane przez platformę Win32.

+

Wielkość liter jest ignorowana zarówno dla poziomu jak podsystemu.

+
+
EGD = ścieżka_do_EGD (tylko Unix)
+ +
+

ścieżka do gniazda programu Entropy Gathering Daemon

+

Opcja pozwala określić ścieżkę do gniazda programu Entropy Gathering Daemon +używanego do zainicjalizowania generatora ciągów pseudolosowych biblioteki +OpenSSL. Opcja jest dostępna z biblioteką OpenSSL 0.9.5a lub nowszą.

+
+
engine = auto | <identyfikator urządzenia>
+ +
+

wybór sprzętowego urządzenia kryptograficznego

+

domyślnie: bez wykorzystania urządzeń kryptograficznych

+

Przykładowa konfiguracja umożliwiająca odczytanie klucza prywatnego z +urządzenia zgodnego z OpenSC:

+
+    engine=dynamic
+    engineCtrl=SO_PATH:/usr/lib/opensc/engine_pkcs11.so
+    engineCtrl=ID:pkcs11
+    engineCtrl=LIST_ADD:1
+    engineCtrl=LOAD
+    engineCtrl=MODULE_PATH:/usr/lib/pkcs11/opensc-pkcs11.so
+    engineCtrl=INIT
+
+    [service]
+    engineNum=1
+    key=id_45
+
+
engineCtrl = <command>[:<parameter>]
+ +
+

konfiguracja urządzenia kryptograficznego

+

Specjalne komendy "LOAD" i "INIT" pozwalają na załadowanie i inicjalizację +modułu kryptograficznego urządzenia.

+
+
fips = yes | no
+ +
+

Włącz lub wyłącz tryb FIPS 140-2.

+

Opcja pozwala wyłączyć wejście w tryb FIPS, jeśli stunnel został skompilowany +ze wsparciem dla FIPS 140-2.

+

domyślnie: yes (pracuj w trybie FIPS 140-2)

+
+
foreground = yes | no (tylko Unix)
+ +
+

tryb pierwszoplanowy

+

Użycie tej opcji powoduje, że stunnel nie przechodzi w tło logując +swoje komunikaty na konsolę zamiast przez syslog (o ile nie użyto +opcji output).

+
+
output = plik
+ +
+

plik, do którego dopisane zostaną logi

+

Użycie tej opcji powoduje dopisanie logów do podanego pliku.

+

Do kierowaniakomunikatów na standardowe wyjście (na przykład po to, żeby +zalogować je programem splogger z pakietu daemontools) można podać jako +parametr urządzenie /dev/stdout.

+
+
pid = plik (tylko Unix)
+ +
+

położenie pliku z numerem procesu

+

Jeżeli argument jest pusty plik nie zostanie stworzony.

+

Jeżeli zdefiniowano katalog chroot, to ścieżka do pid jest określona +względem tego katalogu.

+
+
RNDbytes = liczba_bajtów
+ +
+

liczba bajtów do zainicjowania generatora pseudolosowego

+

W wersjach biblioteki OpenSSL starszych niż 0.9.5a opcja ta określa +również liczbę bajtów wystarczających do zainicjowania PRNG. +Nowsze wersje biblioteki mają wbudowaną funkcję określającą, czy +dostarczona ilość losowości jest wystarczająca do zainicjowania generatora.

+
+
RNDfile = plik
+ +
+

ścieżka do pliku zawierającego losowe dane

+

Biblioteka OpenSSL użyje danych z tego pliku do zainicjowania +generatora pseudolosowego.

+
+
RNDoverwrite = yes | no
+ +
+

nadpisz plik nowymi wartościami pseudolosowymi

+

domyślnie: yes (nadpisz)

+
+
service = nazwa_serwisu (tylko Unix)
+ +
+

użyj parametru jako nazwy serwisu dla biblioteki TCP Wrapper w trybie inetd

+

domyślnie: stunnel

+
+
setgid = identyfikator_grupy (tylko Unix)
+ +
+

grupa z której prawami pracował będzie stunnel

+
+
setuid = identyfikator_użytkownika (tylko Unix)
+ +
+

użytkownik, z którego prawami pracował będzie stunnel

+
+
socket = a|l|r:option=value[:value]
+ +
+

ustaw opcję na akceptującym/lokalnym/zdalnym gnieździe

+

Dla opcji linger wartości mają postać l_onof:l_linger. +Dla opcji time wartości mają postać tv_sec:tv_usec.

+

Przykłady:

+
+    socket = l:SO_LINGER=1:60
+        ustaw jednominutowe przeterminowanie
+        przy zamykaniu lokalnego gniazda
+    socket = r:SO_OOBINLINE=yes

OPCJE USŁUG

+

Każda sekcja konfiguracji usługi zaczyna się jej nazwą ujętą w nawias +kwadratowy. Nazwa usługi używana jest do kontroli dostępu przez +bibliotekę libwrap (TCP wrappers) oraz pozwala rozróżnić poszczególne +usługi w logach.

+

Jeżeli stunnel ma zostać użyty w trybie inetd, gdzie za odebranie +połączenia odpowiada osobny program (zwykle inetd, xinetd +lub tcpserver), należy przeczytać sekcję TRYB INETD poniżej.

+
+
accept = [adres:]port
+ +
+

nasłuchuje na połączenia na podanym adresie i porcie

+

Jeżeli nie został podany adres, stunnel domyślnie nasłuchuje +na wszystkich adresach IPv4 lokalnych interfejsów.

+

Aby nasłuchiwać na wszystkich adresach IPv6 należy użyć:

+
+    accept = :::port
+
+
CApath = katalog_CA
+ +
+

katalog Centrum Certyfikacji

+

Opcja określa katalog, w którym stunnel będzie szukał certyfikatów, +jeżeli użyta została opcja verify. Pliki z certyfikatami muszą +posiadać specjalne nazwy XXXXXXXX.0, gdzie XXXXXXXX jest skrótem +kryptograficznym reprezentacji DER nazwy podmiotu certyfikatu.

+

Funkcja skrótu została zmieniona w wersji 1.0.0 biblioteki OpenSSL. +Należy wykonać c_rehash przy zmianie OpenSSL 0.x.x na 1.x.x.

+

Jeżeli zdefiniowano katalog chroot, to ścieżka do CApath jest określona +względem tego katalogu.

+
+
CAfile = plik_CA
+ +
+

plik Centrum Certyfikacji

+

Opcja pozwala określić położenie pliku zawierającego certyfikaty używane +przez opcję verify.

+
+
cert = plik_pem
+ +
+

plik z łańcuchem certyfikatów

+

Opcja określa położenie pliku zawierającego certyfikaty używane przez +program stunnel do uwierzytelnienia się przed drugą stroną połączenia. +Certyfikat jest konieczny, aby używać programu w trybie serwera. +W trybie klienta certyfikat jest opcjonalny.

+
+
ciphers = lista_szyfrów
+ +
+

lista dozwolonych szyfrów SSL

+

Parametrem tej opcji jest lista szyfrów, które będą użyte przy +otwieraniu nowych połączeń SSL, np.: DES-CBC3-SHA:IDEA-CBC-MD5

+
+
client = yes | no
+ +
+

tryb kliencki (zdalna usługa używa SSL)

+

domyślnie: no (tryb serwerowy)

+
+
connect = [adres:]port
+ +
+

połącz się ze zdalnym serwerem na podany port

+

Jeżeli nie został podany adres, stunnel domyślnie łączy się +z lokalnym serwerem.

+

Komenda może byc użyta wielokrotnie w pojedynczej sekcji +celem zapewnienia wysokiej niezawodności lub rozłożenia +ruchu pomiędzy wiele serwerów.

+
+
CRLpath = katalog_CRL
+ +
+

katalog List Odwołanych Certyfikatów (CRL)

+

Opcja określa katalog, w którym stunnel będzie szukał list CRL, +jeżeli użyta została opcja verify. Pliki z listami CRL muszą +posiadać specjalne nazwy XXXXXXXX.r0, gdzie XXXXXXXX jest skrótem +listy CRL.

+

Funkcja skrótu została zmieniona w wersji 1.0.0 biblioteki OpenSSL. +Należy wykonać c_rehash przy zmianie OpenSSL 0.x.x na 1.x.x.

+

Jeżeli zdefiniowano katalog chroot, to ścieżka do CRLpath jest określona +względem tego katalogu.

+
+
CRLfile = plik_CRL
+ +
+

plik List Odwołanych Certyfikatów (CRL)

+

Opcja pozwala określić położenie pliku zawierającego listy CRL używane +przez opcję verify.

+
+
curve = nid
+ +
+

krzywa dla ECDH

+

Listę dostępnych krzywych można uzyskać poleceniem:

+
+    openssl ecparam -list_curves
+

domyślnie: prime256v1

+
+
delay = yes | no
+ +
+

opóźnij rozwinięcie adresu DNS podanego w opcji connect

+

Opcja jest przydatna przy dynamicznym DNS, albo gdy usługa DNS nie jest +dostępna przy starcie programu stunnel (klient VPN, połączenie wdzwaniane).

+
+
engineNum = <numer urządzenia>
+ +
+

wybierz urządzenie do odczyta klucza prywatnego

+

Urządzenia są numerowane od 1 w górę.

+
+
exec = ścieżka_do_programu
+ +
+

wykonaj lokalny program przystosowany do pracy z superdemonem inetd

+

Jeżeli zdefiniowano katalog chroot, to ścieżka do exec jest określona +względem tego katalogu.

+
+
execargs = $0 $1 $2 ...
+ +
+

argumenty do opcji exec włącznie z nazwą programu ($0)

+

Cytowanie nie jest wspierane w obecnej wersji programu. +Argumenty są rozdzielone dowolną liczbą białych znaków.

+
+
failover = rr | prio
+ +
+

Strategia wybierania serwerów wyspecyfikowanych parametrami "connect".

+
+    rr (round robin) - sprawiedliwe rozłożenie obciążenia
+    prio (priority) - użyj kolejności opcji w pliku konfiguracyjnym
+

domyślnie: rr

+
+
ident = nazwa_użytkownika
+ +
+

weryfikuj nazwę zdalnego użytkownika korzystając z protokołu IDENT (RFC 1413)

+
+
key = plik_klucza
+ +
+

klucz prywatny do certyfikatu podanego w opcji cert

+

Klucz prywatny jest potrzebny do uwierzytelnienia właściciela certyfikatu. +Ponieważ powinien on być zachowany w tajemnicy, prawa do jego odczytu +powinien mieć wyłącznie właściciel pliku. W systemie Unix można to osiągnąć +komendą:

+
+    chmod 600 keyfile
+

domyślnie: wartość opcji cert

+
+
libwrap = yes | no
+ +
+

włącz lub wyłącz korzystanie z /etc/hosts.allow i /etc/hosts.deny.

+

domyślnie: yes

+
+
local = serwer
+ +
+

IP źródła do nawiązywania zdalnych połączeń

+

Domyślnie używane jest IP najbardziej zewnętrznego interfejsu w stronę +serwera, do którego nawiązywane jest połączenie.

+
+
sni = nazwa_usługi:nazwa_serwera (tryb serwera)
+ +
+

Użyj usługi jako podrzędnej (virtualnego serwera) dla rozszerzenia TLS Server +Name Indication (RFC 3546).

+

nazwa_usługi wskazuje usługę nadrzędną, która odbiera połączenia od klientów +przy pomocy opcji accept. nazwa_serwera wskazuje nazwę serwera +wirtualnego. Z pojedyńczą usługą nadrzędną powiązane jest zwykle wiele usług +podrzędnych. Opcja sni może być rownież użyta wielokrotnie w ramach jednej +usługi podrzędnej.

+

Zarówno usługa nadrzędna jak i podrzędna nie może być skonfigurowana w trybie +klienckim. Opcja connect usługi podrzędnej jest ignorowana w połączeniu z +opcją protocol, gdyż połączenie do zdalnego serwera jest w tym wypadku +nawiązywane przed negocjacją TLS. Uwierzytelnienie przy pomocy biblioteki +libwrap jest realizowane dwukrotnie: najpierw dla usługi nadrzędnej po +odebraniu połączenia TCP, a następnie dla usługi podrzędnej podczas negocjacji +TLS.

+

Opcja sni jest dostępna począwszy od wersji 1.0.0 biblioteki OpenSSL.

+
+
sni = nazwa_serwera (tryb klienta)
+ +
+

Użyj parametru jako wartości rozszerzenia TLS Server Name Indication +(RFC 3546).

+

Opcja sni jest dostępna począwszy od wersji 1.0.0 biblioteki OpenSSL.

+
+
OCSP = URL
+ +
+

+
+
OCSPflag = flaga
+ +
+

flaga serwera OCSP

+

aktualnie wspierane flagi: NOCERTS, NOINTERN NOSIGS, NOCHAIN, NOVERIFY, +NOEXPLICIT, NOCASIGN, NODELEGATED, NOCHECKS, TRUSTOTHER, RESPID_KEY, NOTIME

+

Aby wyspecyfikować kilka flag należy użyć OCSPflag wielokrotnie.

+
+
options = opcje_SSL
+ +
+

opcje biblioteki OpenSSL

+

Parametrem jest nazwa opcji zgodnie z opisem w SSL_CTX_set_options(3ssl), +ale bez przedrostka SSL_OP_. +Aby wyspecyfikować kilka opcji należy użyć options wielokrotnie.

+

Na przykład dla zachowania kompatybilności z błędami implementacji SSL +w programie Eudora można użyć opcji:

+
+    options = DONT_INSERT_EMPTY_FRAGMENTS
+
+
protocol = protokół
+ +
+

negocjuj SSL podanym protokołem aplikacyjnym (np. starttls lub stls)

+

Opcji protocol nie należy używać z szyfrowaniem SSL na osobnym porcie.

+

Aktualnie wspierane protokoły:

+

+ +
+

tryb przezroczystego proxy na wspieranych platformach

+

Wspierane opcje:

+
+
none
+ +
+

Zablokuj wsparcie dla przezroczystago proxy. Jest to wartość domyślna.

+
+
source
+ +
+

Przepisz adres, aby nawiązywane połączenie wydawało się pochodzić +bezpośrednio od klienta, a nie od programu stunnel.

+

Opcja jest aktualnie obsługiwana w:

+
+
Trybie zdalnym (opcja connect) w systemie Linux >=2.6.28
+ +
+

Konfiguracja wymaga następujących ustawień iptables oraz routingu +(na przykład w pliku /etc/rc.local lub analogicznym):

+
+    iptables -t mangle -N DIVERT
+    iptables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT
+    iptables -t mangle -A DIVERT -j MARK --set-mark 1
+    iptables -t mangle -A DIVERT -j ACCEPT
+    ip rule add fwmark 1 lookup 100
+    ip route add local 0.0.0.0/0 dev lo table 100
+    echo 0 >/proc/sys/net/ipv4/conf/lo/rp_filter
+

Konfiguracja ta wymaga, aby stunnel był wykonywany jako root i bez opcji setuid.

+
+
Trybie zdalnym (opcja connect) w systemie Linux 2.2.x
+ +
+

Konfiguracja ta wymaga skompilowania jądra z opcją transparent proxy. +Docelowa usługa musi być umieszczona na osobnej maszynie, do której routing +kierowany jest poprzez serwer stunnela.

+

Dodatkowo stunnel powinien być wykonywany jako root i bez opcji setuid.

+
+
Trybie zdalnym (opcja connect) w systemie FreeBSD >=8.0
+ +
+

Konfiguracja ta wymaga skonfigurowania firewalla i routingu. +stunnel musi być wykonywany jako root i bez opcji setuid.

+
+
Trybie lokalnym (opcja exec)
+ +
+

Konfiguracja ta jest realizowana przy pomocy biblioteki libstunnel.so. +Do załadowania biblioteki wykorzystywana jest zmienna środowiskowa _RLD_LIST na +platformie Tru64 lub LD_PRELOAD na innych platformach.

+
+
+
+
destination
+ +
+

Oryginalny adres docelowy jest używany zamiast opcji connect.

+

Przykładowana konfiguracja przezroczystego adresu docelowego:

+
+    [transparent]
+    client=yes
+    accept=<port_stunnela>
+    transparent=destination
+

Konfiguracja wymaga następujących ustawień iptables +(na przykład w pliku /etc/rc.local lub analogicznym):

+
+    /sbin/iptables -I INPUT -i eth0 -p tcp --dport <port_stunnela> -j ACCEPT
+    /sbin/iptables -t nat -I PREROUTING -i eth0 -p tcp --dport <port_przekierowany> -j DNAT --to-destination <lokalne_ip>:<port_stunnela>
+

Przezroczysty adres docelowy jest aktualnie wspierany wyłącznie w systemie Linux.

+
+
both
+ +
+

Użyj przezroczystego proxy zarówno dla adresu źródłowego jak i docelowego.

+
+
+

Dla zapewnienia kompatybilności z wcześniejszymim wersjami wspierane są dwie +dodatkowe opcje:

+
+
yes
+ +
+

Opcja została przemianowana na source.

+
+
no
+ +
+

Opcja została przemianowana na none.

+
+
+
+
verify = poziom
+ +
+

weryfikuj certyfikat drugiej strony połączenia

+
+
poziom 0 - zarządaj certyfikatu i zignoruj go
+ +
poziom 1 - weryfikuj, jeżeli został przedstawiony
+ +
poziom 2 - weryfikuj z zainstalowanym certyfikatem Centrum Certyfikacji
+ +
poziom 3 - weryfikuj z lokalnie zainstalowanym certyfikatem drugiej strony
+ +
poziom 4 - weryfikuj z certyfikatem drugiej strony ignorując łańcuch CA
+ +
domyślnie - nie weryfikuj
+ +
+
+
+

+

+
+

ZWRACANA WARTOŚĆ

+

stunnel zwraca zero w przypadku sukcesu, lub wartość niezerową +w przypadku błędu.

+

+

+
+

SIGNAŁY

+

Następujące sygnały mogą być użyte do sterowania programem w systemie Unix:

+
+
SIGHUP
+ +
+

Załaduj ponownie plik konfiguracyjny.

+

Niektóre globalne opcje nie będą przeładowane:

+ +

Jeżeli wykorzystywana jest opcja 'setuid' stunnel nie będzie mógł załadować +ponownie konfiguracji wykorzystującej uprzywilejowane (<1024) porty.

+

Jeżeli wykorzystywana jest opcja 'chroot' stunnel będzie szukał wszystkich +potrzebnych plików (łącznie z plikiem konfiguracyjnym, certyfikatami, logiem i +plikiem pid) wewnątrz katalogu wskazanego przez 'chroot'.

+
+
SIGUSR1
+ +
+

Zamknij i otwórz ponownie log. +Funkcja ta może zostać użyta w skrypcie rotującym log programu stunnel.

+
+
SIGTERM, SIGQUIT, SIGINT
+ +
+

Zakończ działanie programu.

+
+
+

Skutek wysłania innych sygnałów jest niezdefiniowany.

+

+

+
+

PRZYKŁADY

+

Szyfrowanie połączeń do lokalnego serwera imapd można użyć:

+
+    [imapd]
+    accept = 993
+    exec = /usr/sbin/imapd
+    execargs = imapd
+

albo w trybie zdalnym:

+
+    [imapd]
+    accept = 993
+    connect = 143
+

W połączeniu z programem pppd stunnel pozwala zestawić prosty VPN. +Po stronie serwera nasłuchującego na porcie 2020 jego konfiguracja +może wyglądać następująco:

+
+    [vpn]
+    accept = 2020
+    exec = /usr/sbin/pppd
+    execargs = pppd local
+    pty = yes
+

Poniższy plik konfiguracyjny może być wykorzystany do uruchomienia +programu stunnel w trybie inetd. Warto zauważyć, że w pliku +konfiguracyjnym nie ma sekcji [nazwa_usługi].

+
+    exec = /usr/sbin/imapd
+    execargs = imapd
+

+

+
+

NOTKI

+

+

+

OGRANICZENIA

+

stunnel nie może być używany do szyfrowania protokołu FTP, +ponieważ do przesyłania poszczególnych plików używa on dodatkowych +połączeń otwieranych na portach o dynamicznie przydzielanych numerach. +Istnieją jednak specjalne wersje klientów i serwerów FTP pozwalające +na szyfrowanie przesyłanych danych przy pomocy protokołu SSL.

+

+

+

TRYB INETD (tylko Unix)

+

W większości zastosowań stunnel samodzielnie nasłuchuje na porcie +podanym w pliku konfiguracyjnym i tworzy połączenie z innym portem +podanym w opcji connect lub nowym programem podanym w opcji exec. +Niektórzy wolą jednak wykorzystywać oddzielny program, który odbiera +połączenia, po czym uruchamia program stunnel. Przykładami takich +programów są inetd, xinetd i tcpserver.

+

Przykładowa linia pliku /etc/inetd.conf może wyglądać tak:

+
+    imaps stream tcp nowait root /usr/bin/stunnel
+        stunnel /etc/stunnel/imaps.conf
+

Ponieważ w takich przypadkach połączenie na zdefiniowanym porcie +(tutaj imaps) nawiązuje osobny program (tutaj inetd), stunnel +nie może używać opcji accept. W pliku konfiguracyjnym nie może +być również zdefiniowana żadna usługa ([nazwa_usługi]), ponieważ +konfiguracja taka pozwala na nawiązanie tylko jednego połączenia. +Wszystkie OPCJE USŁUG powinny być umieszczone razem z opcjami +globalnymi. Przykład takiej konfiguracji znajduje się w sekcji +PRZYKŁADY.

+

+

+

CERTYFIKATY

+

Protokół SSL wymaga, aby każdy serwer przedstawiał się nawiązującemu +połączenie klientowi prawidłowym certyfikatem X.509. +Potwierdzenie tożsamości serwera polega na wykazaniu, że posiada on +odpowiadający certyfikatowi klucz prywatny. +Najprostszą metodą uzyskania certyfikatu jest wygenerowanie +go przy pomocy wolnego pakietu OpenSSL. Więcej informacji na temat +generowania certyfikatów można znaleźć na umieszczonych poniżej stronach.

+

Istotną kwestią jest kolejność zawartości pliku .pem. +W pierwszej kolejności powinien on zawierać klucz prywatny, +a dopiero za nim podpisany certyfikat (nie żądanie certyfikatu). +Po certyfikacie i kluczu prywatnym powinny znajdować się puste linie. +Jeżeli przed certyfikatem znajdują się dodatkowe informacje tekstowe, +to powinny one zostać usunięte. Otrzymany plik powinien mieć +następującą postać:

+
+    -----BEGIN RSA PRIVATE KEY-----
+    [zakodowany klucz]
+    -----END RSA PRIVATE KEY-----
+    [pusta linia]
+    -----BEGIN CERTIFICATE-----
+    [zakodowany certyfikat]
+    -----END CERTIFICATE-----
+    [pusta linia]
+

+

+

LOSOWOŚĆ

+

stunnel potrzebuje zainicjować PRNG (generator liczb pseudolosowych), +gdyż protokół SSL wymaga do bezpieczeństwa kryptograficznego źródła +dobrej losowości. Następujące źródła są kolejno odczytywane aż do +uzyskania wystarczającej ilości entropii:

+ +

Współczesne (>=0.9.5a) wersje biblioteki OpenSSL automatycznie +zaprzestają ładowania kolejnych danych w momencie uzyskania wystarczającej +ilości entropii. Wcześniejsze wersje biblioteki wykorzystają wszystkie +powyższe źródła, gdyż nie istnieje tam funkcja pozwalająca określić, +czy uzyskano już wystarczająco dużo danych.

+

Warto zwrócić uwagę, że na maszynach z systemem Windows, na których +konsoli nie pracuje użytkownik, zawartość ekranu nie jest wystarczająco +zmienna, aby zainicjować PRNG. W takim przypadku do zainicjowania +generatora należy użyć opcji RNDfile.

+

Plik RNDfile powinien zawierać dane losowe -- również w tym sensie, +że powinny być one inne przy każdym uruchomieniu programu stunnel. +O ile nie użyta została opcja RNDoverwrite jest to robione +automatycznie. Do ręcznego uzyskania takiego pliku użyteczna +może być komenda openssl rand dostarczana ze współczesnymi +wersjami pakietu OpenSSL.

+

Jeszcze jedna istotna informacja -- jeżeli dostępne jest urządzenie +/dev/urandom biblioteka OpenSSL ma zwyczaj zasilania nim PRNG w trakcie +sprawdzania stanu generatora. W systemach z /dev/urandom urządzenie +to będzie najprawdopodobniej użyte, pomimo że znajduje się na samym końcu +powyższej listy. Jest to właściwość biblioteki OpenSSL, a nie programu +stunnel.

+

+

+

PARAMETRY DH

+

Począwszy od wersji 4.40 stunnel zawiera w kodzie programu 2048-bitowe +parametry DH.

+

Alternatywnie parametry DH można umieścić w pliku razem z certyfikatem:

+
+    openssl dhparam 2048 >> stunnel.pem
+

Wygenerowanie parametrów DH może zająć nawet wiele minut.

See the I section for example +configurations. + +=head2 CERTIFICATES + +Each SSL enabled daemon needs to present a valid X.509 certificate +to the peer. It also needs a private key to decrypt the incoming +data. The easiest way to obtain a certificate and a key is to +generate them with the free I package. You can find more +information on certificates generation on pages listed below. + +The order of contents of the I<.pem> file is important. It should contain the +unencrypted private key first, then a signed certificate (not certificate +request). There should be also empty lines after certificate and private key. +Plaintext certificate information appended on the top of generated certificate +should be discarded. So the file should look like this: + + -----BEGIN RSA PRIVATE KEY----- + [encoded key] + -----END RSA PRIVATE KEY----- + [empty line] + -----BEGIN CERTIFICATE----- + [encoded certificate] + -----END CERTIFICATE----- + [empty line] + +=head2 RANDOMNESS + +B needs to seed the PRNG (pseudo random number generator) in +order for SSL to use good randomness. The following sources are loaded +in order until sufficient random data has been gathered: + +=over 4 + +=item * The file specified with the I flag. + +=item * The file specified by the RANDFILE environment variable, if set. + +=item * The file .rnd in your home directory, if RANDFILE not set. + +=item * The file specified with '--with-random' at compile time. + +=item * The contents of the screen if running on Windows. + +=item * The egd socket specified with the I flag. + +=item * The egd socket specified with '--with-egd-sock' at compile time. + +=item * The /dev/urandom device. + +=back + +With recent (>=OpenSSL 0.9.5a) version of SSL it will stop loading +random data automatically when sufficient entropy has been gathered. +With previous versions it will continue to gather from all the above +sources since no SSL function exists to tell when enough data is available. + +Note that on Windows machines that do not have console user interaction +(mouse movements, creating windows, etc.) the screen contents are not +variable enough to be sufficient, and you should provide a random file +for use with the I flag. + +Note that the file specified with the I flag should contain +random data -- that means it should contain different information +each time B is run. This is handled automatically +unless the I flag is used. If you wish to update this file +manually, the I command in recent versions of OpenSSL, +would be useful. + +One important note -- if /dev/urandom is available, OpenSSL has a habit of +seeding the PRNG with it even when checking the random state, so on +systems with /dev/urandom you're likely to use it even though it's listed +at the very bottom of the list above. This isn't B behaviour, it's +OpenSSLs. + +=head2 DH PARAMETERS + +Stunnel 4.40 and later contains hardcoded 2048-bit DH parameters. + +It is also possible to specify DH parameters in the certificate file: + + openssl dhparam 2048 >> stunnel.pem + +DH parameter generation may take several minutes. + + +=head1 FILES + +=over 4 + +=item F + +B configuration file + +=back + + +=head1 BUGS + +Option I does not support quoting. + + +=head1 SEE ALSO + +=over 4 + +=item L + +access control facility for internet services + +=item L + +internet 'super-server' + +=item F + +B homepage + +=item F + +OpenSSL project website + +=back + + +=head1 AUTHOR + +=over 4 + +=item Michał Trojnara + +> + +=back + diff --git a/m4/libtool.m4 b/m4/libtool.m4 new file mode 100644 index 0000000..a3fee53 --- /dev/null +++ b/m4/libtool.m4 @@ -0,0 +1,7377 @@ +# libtool.m4 - Configure libtool for the host system. -*-Autoconf-*- +# +# Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2003, 2004, 2005, +# 2006, 2007, 2008 Free Software Foundation, Inc. +# Written by Gordon Matzigkeit, 1996 +# +# This file is free software; the Free Software Foundation gives +# unlimited permission to copy and/or distribute it, with or without +# modifications, as long as this notice is preserved. + +m4_define([_LT_COPYING], [dnl +# Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2003, 2004, 2005, +# 2006, 2007, 2008 Free Software Foundation, Inc. +# Written by Gordon Matzigkeit, 1996 +# +# This file is part of GNU Libtool. +# +# GNU Libtool is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of +# the License, or (at your option) any later version. +# +# As a special exception to the GNU General Public License, +# if you distribute this file as part of a program or library that +# is built using GNU Libtool, you may include this file under the +# same distribution terms that you use for the rest of that program. +# +# GNU Libtool is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
