Missing bytes?
by Arthur Murray 01 Jan '12

01 Jan '12

Hello, When I telnet to my pop3 server and "QUIT" this is what I see: Escape character is '^]'. +OK InterMail POP3 server ready. QUIT +OK ? InterMail POP3 server signing off. Connection closed by foreign host. When I setup an stunnel 4.5 to the same pop3 server: [pop3s] accept = 995 connect = server:110 and connect with "openssl s_client -connect localhost:995" this is what I see: +OK InterMail POP3 server ready. QUIT DONE And the stunnel log reports: Connection closed: 34 bytes sent to SSL, 0 bytes sent to socket What happened to the last line "+OK ? InterMail POP3 server signing off." and why aren't the counters counting the 5 bytes I sent ("QUIT\n") and the last line of 41 sent over the SSL? Example 2 through stunnel: +OK InterMail POP3 server ready. USER -ERR a user name MUST be entered QUIT DONE Connection closed: 68 bytes sent to SSL, 5 bytes sent to socket (still missing the last bytes)

Hi all, I'am trying to encrypt a connection between two hosts using stunnel. ----- here is my config file ---- cert = /usr/local/etc/stunnel/stunnel.pem chroot = /usr/local/var/lib/stunnel/ setuid = nobody setgid = nogroup pid = /stunnel.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 debug = debug output = stunnel.log --- [rdps] accept = 1957 connect = remote_machine:3389 Avery think was working fine until I tried to telnet to the port 1957 on the machine running stunnel, the process stunnel was killed alone leaving this in /var/log/messages : Dec 20 16:58:01 alpha kernel: [4930384.164316] stunnel[14540]: segfault at 8 ip b7629b61 sp b758d16c error 6 in libc-2.7.so[b75bd000+138000] Does anybody have an idea about this problem, thanks in advance, Yassine

Re: [stunnel-users] Configuring VeriSign certificate with STunnel

Hi Guys, Thanks for your replies. I tried following commands on verisign c certificate, for both of these do not work. There is error 'unable to load certificate'. openssl x509 -inform DER -in stunnel.pem -noout -text or openssl x509 -inform PEM -in stunnel.pem -noout -text however if I run same command (openssl x509 -inform PEM -in stunnel.pem -noout -text) on VeriSign root & Intermediate certificate it works. It shows format should be 'pem'. But somehow certificate is not valid. I am using following commands to create csr and private key. Are these correct ? openssl genrsa -des3 -out server.key 2048 openssl req -new -key server.key -out server.csr Thanks, Zubair -----Original Message----- From: stunnel-users-bounces(a)stunnel.org [mailto:[email protected]] On Behalf Of stunnel-users-request(a)stunnel.org Sent: Wednesday, December 21, 2011 9:27 PM To: stunnel-users(a)stunnel.org Subject: stunnel-users Digest, Vol 89, Issue 21 Send stunnel-users mailing list submissions to stunnel-users(a)stunnel.org To subscribe or unsubscribe via the World Wide Web, visit http://stunnel.mirt.net/mailman/listinfo/stunnel-users or, via email, send a message with subject or body 'help' to stunnel-users-request(a)stunnel.org You can reach the person managing the list at stunnel-users-owner(a)stunnel.org When replying, please edit your Subject line so it is more specific than "Re: Contents of stunnel-users digest..."

I am using stunnel v. 4.41. I am relatively new to stunnel myself. The env. is as follows: We are trying to secure an rdp connection from a java applet running in a web browser into a windows 2008 server machine behind our firewall. Presently, the java applet opens up an RDP connection into a machine (I will call it the SSL machine) where Stunnel is presently installed. Stunnel then forwards properly the incoming traffic (from portA) into its final destination (i.e: the windows Server 2008 machine) on port B. Further, I have configured Stunnel to use an SSL certificate. (Although, I have not been able to test that yet to make sure it works) Anyhow, it is all working as expected and I am pretty happy about the proof of concept. However, while testing it a bit, I noticed that it was relatively easy to bring stunnel down. The way I went about it, was to simply run a "telnet IP_of_MySSLMachine portA" from any DOS command window from any machine with internet access. From the Stunnel logs, I can tell that I get a response from Stunnel and on the DOS window side, I have a cursor waiting for input.... Writing any gibberish into that DOS windows and waiting a little bit makes stunnel stop and die in the SSL machine.

Question: I was wondering if you guys could shed some light into this behavior. Is it a known behavior/bug? Is there a way to solve it by maybe upgrading into a later version of stunnel? Also, I was thinking to block telnet altogether at the firewall level, but then I am not sure what other protocols could people use to hack into the system...so should I block all of them?

Hi, Can I develop an application based on OpenSSL such that it can communicate with all trusted sites ? Like browser can communicates? Actually I have desktop application that uses SSL. Now this application may communicate with any trusted server application. How can I achieve this ?

Incompatibility between openssl 1.0.0 and 0.9.8 which cause stunnel windows version malfunction.
by ayanamist 21 Dec '11

21 Dec '11

I generated a pair of key and certificates with openssl 1.0.0d, and use them in stunnel 4.36. Today i upgrade it to stunnel 4.50 and it doesnot work. All configurations remain unmodified. Then i tested many versions and found, stunnel with openssl 1.00 works fine while with openssl 0.98 does not work. I use stunnel with linux server and windows client, stunnel 4.50 windows version is using openssl 0.98, so cause this problem. 4.47 is using 1.00e which i think is newer than 0.98 bundled with 4.50. So why stunnel keep changing openssl version?

Hi, Here are steps how I created certificate request and private key. Generate private key openssl genrsa -des3 -out server.key 2048 Generate certificate request openssl req -new -key server.key -out server.csr I submitted server.csr contents to VeriSign to get test certificate and they provided me three certificates. VeriSign signed certificated Root certificate Intermediate certificate I copied VeriSign signed certificate in stunnel.pem and other two certificates in ca.pem file.

Configuring VeriSign certificate with STunnel
by Zubair Ali Mansoor 21 Dec '11

21 Dec '11

Hi, I got VeriSign Test SSL certificate. I have been trying to configure it with STunnel. But there are errors in STunnel. I have placed private key and CA signed certificate in a separate file named 'stunnel.pem'. Root and Intermediate certificates have been placed in following order in a file named 'ca.pem' stunnel.pem -----BEGIN RSA PRIVATE KEY----- encrypted key -----END RSA PRIVATE KEY----- -----BEGIN CERTIFICATE----- VeriSign signed certificate -----END CERTIFICATE----- ca.pem -----BEGIN CERTIFICATE----- VeriSign Intermediate CA Certificate -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- VeriSign Root CA Certificate -----END CERTIFICATE----- Here is stunnel.conf file. ;key = server.key cert = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS ; Authentication stuff verify = 2 ; Don't forget to c_rehash CApath ;CApath = certs ; It's often easier to use CAfile CAfile = ca.pem ;CAfile=zosIntermediate.pem ; Don't forget to c_rehash CRLpath ;CRLpath = crls ; Alternatively you can use CRLfile ;CRLfile = crls.pem ; Some debugging stuff useful for troubleshooting ;debug = 7 output = stunnel.log ; Use it for client mode client = no I have also tried to change order of certificates but nothing is working. Anyone have idea how it can work. Your cooperation will be highly appreciated. Thanks, Zubair

Unable to make Stunnel on Solaris 10
by ted.pritchard＠steria.co.uk 20 Dec '11

20 Dec '11

Hi, I'm trying to compile and install Stunnel 4.47 on a Solaris 10 container. My GCC version is 3.4.3. The problem is that I get the following error during make make gcc:unrecognized option: '-pthread' Should I be able to compile Stunnel using this configuration or is there some option I can use to make it work? For interest, In the past using Stunnel 3.34 I've not had this problem so something in the build process must have changed. Many Thanks Ted This email originates from Steria*.

Multiple Domains for https
by Brian McGinity 15 Dec '11

15 Dec '11

Will Stunnel work with multiple domains? For example if abc.com and xyz.com both resolve to the same ip address where the web server is running locally on port 4080. Going when to https://abc.com or https://xyz.com stunnel will encrypt the traffic and forward to the local 4080 port in the clear. What if 10 or 20 domains needed to be served by the same web server?

Is Stunnel Right Tool for....?
by Brian McGinity 14 Dec '11

14 Dec '11

Is Stunnel the right tool for this situation? I am using an Intel disk monitoring tool which has the ability to send out email alerts. In the Email Setup it asks for Host, From and To, there is not a username or pw. Could Stunnel be configured to add the username and pw and send the message to gmail's smtp?

Problem with sslv2 clients
by Markus Borst 09 Dec '11

09 Dec '11

Hi, we have a strange problem with newer stunnel versions (4.50 on windows), compared to older ones (known to work is version 4.35). The problem seems to be, that if a client sends a SSLv2 Helo message, the stunnel server simply resets the TCP connection, without trying to negotioate anything. Setup: Stunnel is used top provide ssl/tls for imap, Hobbit is used to monitor service availability. The Hobbit module to monitor imaps seems to try SSLv2 first, but also supports newer versions (SSLv3 and TLSv1). The ssl connection never gets established, stunnel sends a tcp RST, hobbit never retries. We can force some hobbit modules to use TLSv1 exclusively, but not all of them. We fear that some older mailclients will also have problems initiating a connection, so we keep stunnel 4.35 running for now. stunnel.conf: fips = no debug = 7 output = stunnel.log [imaps] accept = 130.83.174.1:993 connect = 127.0.0.1:143 cert = imap.xxx.company.yy.pem stunnel.log: 2011.12.09 14:55:12 LOG5[6820:2144]: Service imaps accepted connection from xxx.yyy.zzz.105:45294 2011.12.09 14:55:12 LOG3[6820:2144]: SSL_accept: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number 2011.12.09 14:55:12 LOG5[6820:2144]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2011.12.09 14:55:12 LOG7[6820:2144]: Service imaps finished (0 left) 2011.12.09 14:55:12 LOG7[6820:2144]: str_stats: 0 block(s), 0 data byte(s), 0 control byte(s) Wireshark Packet Trace (see attached image). What's wrong here? Shouldn't client and server negotiate the methods used? The client seems to offer TLS ("Version: TLS 1.0 ..."), but instead of negotiating, the server simply closes the connection. Greetings Markus Borst

FIPS on Win7
by james.poole＠rsa.com 01 Dec '11

01 Dec '11

It looks like there is a known issue with FIPS running on Windows 7 from the mail archives. Is there something I could do to help get this fixed? I was planning on using stunnel to allow a FIPS compliant transmission of data over the wire. Win7 - 32bit Output - From the console window: stunnel 4.49 on x86-pc-mingw32-gnu platform Compiled/running with OpenSSL 0.9.8r-fips 8 Feb 2011 Threading:WIN32 SSL:ENGINE,FIPS Auth:none Sockets:SELECT,IPv6 Reading configuration from file stunnel.conf FIPS_mode_set: 2D06906E: error:2D06906E:FIPS routines:FIPS_CHECK_INCORE_FINGERPRINT:fingerprint does not match Old Thread: http://www.stunnel.org/pipermail/stunnel-users/2011-November/003374.html Thanks for any help, James

Key and Certificate file issue!
by Hamid.Shahid＠sungard.com 30 Nov '11

30 Nov '11

Hi, I am trying to establish a SSL connection with a remote server on a random port 10170. I have got a public key from the server side. And I have sent my public key to the server. And I am trying to use my certificate file and the public key of the server like this. cert = sunPrimary.pem key = sunStunnel.pem But the problem is both the public key from server and my own certificate file starts with "-----BEGIN CERTIFICATE-----" by default. So now, if I don't change the "-----BEGIN CERTIFICATE-----" header of the my certificate to "-----BEGIN PRIVATE KEY-----" I get errors and if I change it to private key and make the public key of the server as certificate then I still get errors. Please let me know, how can I use the key and certificate together. Thanks. Kind Regards, Hamid Shahid

Pop3, CAPA before STLS (allow stunnel to work with android devices using proto pop3 option).
by Anthony Morgan 30 Nov '11

30 Nov '11

Hi, I'm running a pop3 server on a non-standard port and having stunnel listen on both 110 and 995 like so: [pop3_ssl] accept = 995 connect = ... [pop3_tls] accept = 110 connect = ... protocol = pop3 When connecting from an android device (2.3 on Nexus S at least), it confirms the server supports STLS using CAPA (and seemingly will not configure otherwise), so I modified protocol.c to announce support: < fdputline(c, c->local_wfd.fd, "+OK Stunnel capability list follows"); < fdputline(c, c->local_wfd.fd, "STLS"); < fdputline(c, c->local_wfd.fd, "."); --- > fdputline(c, c->local_wfd.fd, "-ERR Stunnel does not support capabilities"); It seems to me that there is no harm in this, because the RFC states that the client MUST recheck the servers capabilities with another CAPA command after starting TLS. It may be better to check the servers actual capabilities, add STLS to them and return that, but this does work. Any thoughts or comments? Tony Morgan --- Sent from Post.fm

Hi, I have an application which uses stunnel. Using stunnel 4.25 everything works fine.

Stunnel compilation issue on Mac OS X 10.5 powerpc
by Cedric Lor 28 Nov '11

28 Nov '11

Hi, I've been trying to compile stunner (4.47) on a power pc Mac OS X Leopard (OS X 10.5) platform after a manual update to openssl v.1.0.0.e ggc is version 4.0.1. I run into an error according to which there would be undefined symbols in stunnel-ctx.o (see make output below). I can't figure out to which feature stunner-ctx.o is related, whether I need this feature and how to disable it in ./configure if I don't need it. Please note that I managed to install stunner 4.46 via fink on the same machine (such fink install of stunnel required installing a specific instance of openssl (v.1.0.0.0.e) within fink). Would anyone be able to identify from the make output below whether the issue comes from stunnel or from my openssl manual install? Many thanks.

stunnel & HAProxy : patch still required ?
by Thomas Manson 24 Nov '11

24 Nov '11

Hi, I'm willing to use this kind of configuration : https client -->stunnel --> haproxy --> 2 web servers in http (or more) I've understand that haproxy can't handle the ssl part, that's why stunnel is needed. I've read that a Patch is required for stunnel to work with haproxy in this kind of confirmation "I run stunnel 4.32 with patch from http://haproxy.1wt.eu/download/patches/ on port 443 and forward it to port 81 on the same machine which is bound to haproxy." Can anyone tell me if this patch is now included in stunnel, in particular, does Ubuntu 11.10 include it ? I really would rather stay with package provided by ubuntu in order to have easy upgrade/security fix. I've experiences the work overload of manually compiling everything in Apache for instance ;) Any advices on this kind of setup ? documentation pointers? best practices ?

The concept is that having non-SSL aware daemons running on your system you can easily setup them to communicate with clients over secure SSL channel. stunnel can be used to add SSL functionality to commonly used inetd daemons like POP-2, POP-3 and IMAP servers without any changes in the programs' code.

Patch: Include source IP in connection failure log lines
by Alex Gottschalk 23 Nov '11

23 Nov '11

I'm setting up an internet-facing server that will be running a service wrapped with stunnel. Given that, it made sense to me to use fail2ban to block repeat connection attempts from clients who don't have the right certificate (the system is using client-certificate authentication). Unfortunately, stunnel4 doesn't put the client source IP in connection failure log lines, so I made this quick patch to enable that. ---cut here---- --- src/client.c.orig 2011-10-05 16:47:48.000000000 -0700 +++ src/client.c 2011-10-05 16:50:37.000000000 -0700 @@ -358,10 +358,13 @@ continue; } } - if(c->opt->option.client) + if(c->opt->option.client) { sslerror("SSL_connect"); - else - sslerror("SSL_accept"); + } else { + char buf[255]; + sprintf(buf, "SSL_accept from %s ", c->accepted_address); + sslerror(buf); + } longjmp(c->err, 1); } if(SSL_session_reused(c->ssl)) { ----cut here----

Getting Stunnel to work
by Brian Miller 21 Nov '11

21 Nov '11

Hello, I recently moved my Homeseer software from web server 08 to server 08. I had stunnel working on there properly to send out e mails using a hotmail account. I downloaded the new verison of Stunnel and tried to use the same config but Stunnel was crashing. Both versions web server 08 and server 08 are 64bit. Below is the original stunnel config file that I used on web server 08, this is cashing stunnel to crash when I run it. Using the default settings works, but I need to edit the config. I'm not to smart in the whole stunnel / Homeseer side of things. I was told by the Homeseer community that I need this to use my hotmail e mail to send e mails. ; Sample stunnel configuration file by Michal Trojnara 2002-2006 ; Some options used here may not be adequate for your particular configuration ; Certificate/key is needed in server mode and optional in client mode ; The default certificate is provided only for testing and should not ; be used in a production environment cert = stunnel.pem ;key = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS ; Authentication stuff ;verify = 2 ; Don't forget to c_rehash CApath ;CApath = certs ; It's often easier to use CAfile ;CAfile = certs.pem ; Don't forget to c_rehash CRLpath ;CRLpath = crls ; Alternatively you can use CRLfile ;CRLfile = crls.pem ; Some debugging stuff useful for troubleshooting ;debug = 7 ;output = stunnel.log ; Use it for client mode client = yes ; Service-level configuration [pop3s] accept = 110 connect = pop3.live.com:995 [imaps] accept = 993 connect = 143 [ssmtp] accept = 25 connect = smtp.live.com:587 protocol = smtp ;[https] ;accept = 443 ;connect = 80 ;TIMEOUTclose = 0 ; vim:ft=dosini

stunnel 4.47 released

Dear Users, I have released version 4.47 of stunnel. This version includes a number of important bugfixes. The ChangeLog entry: Version 4.47, 2011.11.21, urgency: MEDIUM: * Internal improvements - CVE-2010-3864 workaround improved to check runtime version of OpenSSL rather than compiled version, and to allow OpenSSL 0.x.x >= 0.9.8p. - Encoding of man page sources changed to UTF-8. * Bugfixes - Handling of socket/SSL close in transfer() function was fixed. - Logging was modified to save and restore system error codes. - Option "service" was restricted to Unix, as since stunnel 4.42 it wasn't doing anything useful on Windows platform.

For a few weeks now, the sever has an expired certificate, so I get an error while connecting to it. The stunnel.log looks like that: 2011.11.18 12:23:36 LOG5[753:3078719168]: stunnel 4.29 on i486-pc-linux-gnu with OpenSSL 0.9.8o 01 Jun 2010 2011.11.18 12:23:36 LOG5[753:3078719168]: Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP 2011.11.18 12:23:36 LOG5[753:3078719168]: 500 clients allowed 2011.11.18 12:24:00 LOG5[759:3078716272]: https accepted connection from 127.0.0.1:40691 2011.11.18 12:24:00 LOG5[759:3078716272]: connect_blocking: connected example.com:443 2011.11.18 12:24:00 LOG5[759:3078716272]: https connected remote server from my_outside_ip:38486 2011.11.18 12:24:00 LOG3[759:3078716272]: SSL_connect: 14094415: error:14094415:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate expired 2011.11.18 12:24:00 LOG5[759:3078716272]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket This happens, when connecting manually with "nc -v 127.0.0.1 1234" to make a http-get request.

[patch] x-forwarded-for patch for the new stunnel 4.46
by Michel Belleau 18 Nov '11

18 Nov '11

Hi. I use HAProxy and STunnel and I had to do a new installation lately. I took time to check the latest versions available of each product as this is a good time to test it out before production roll-out. I figured out that enough things have changed from STunnel version 4.44 to 4.46 making the X-Forwarded-For patch (that is usually used when STunnel sits in front of HAProxy) reject some parts of the latest 4.44 patch I found on the internet. Here is the patch, applying with no problems on 4.46, for anyone else interested: http://labs.malaiwah.com/stunnel-4.46-xforwarded-for.diff PS: I didn't try it yet for IPv6 connections yet.

Multiple Windows Services
by John W 14 Nov '11

14 Nov '11

I upgraded from stunnel 4.34 to 4.46 (Windows) today, which took much more time than expected. First, I was surprised to see that my specified service name (via "service =" was ignored), until I eventually found the note in the 4.42 changelog about "Removed support for changing Windows Service name with "service"". This isn't the end of the world (I changed the display name using sc) but it would be very helpful -- and time saving -- if the man page was updated to reflect this change. A bigger issue I ran into is that because the service can't be renamed, I can have only one stunnel service installed. The only mention of this I found was a reply to a list question saying "Running more than one stunnel service has been obsoleted." What was the motivation behind this change? Though I can specify multiple [service] sections in stunnel.conf, I see no way to control them individually. It has been useful to have separate stunnel (Windows) services installed, which can be stopped and started independently. Thanks.

[PATCH]: Debugging output
by Andrew Watts 08 Nov '11

08 Nov '11

Hi. According to the manpage for the output=<file> configuration directive, if this is set then it should replace syslog facility logging. However, stunnel 4.45 (and ealier version) on linux send debugging information to both syslog and a logfile when output is specified. The following patch makes stunnel behave according to the manpage "append log messages to a file instead of using syslog": ==================================== --- a/src/log.c +++ b/src/log.c @@ -163,7 +163,7 @@ static void log_raw(const int level, con line=str_printf("%s %s: %s", stamp, id, text); if(level<=global_options.debug_level) { #if !defined(USE_WIN32) && !defined(__vms) - if(global_options.option.syslog) + if(global_options.option.syslog && !global_options.output_file) syslog(level, "%s: %s", id, text); #endif /* USE_WIN32, __vms */ if(outfile) ==================================== ~ Andy

Error detected on socket (read) file descriptor: Broken pipe (32)
by Alex Magee 08 Nov '11

08 Nov '11

Hello, I'm trying to use stunnel to workaround a wine bug which prevents an old Windows mail client from accessing my mail server through a pop3s 995 port. I'm not an expert on linux, stunnel, sockets or ssl. The process seems to start off well, establishes a connection to the correct remote mail server, and negotiates an ssl connection, but then terminates with: Error detected on socket (read) file descriptor: Broken pipe (32) I've played with various settings in the stunnel.conf file, but with no success. A Google search turned up one other example of this problem back in Nov 2010, but no solution was forthcoming. Does anyone have any suggestions of what might be the problem? The level 7 debug stunnel.log file follows at the end, with TCP addresses masked. The system is SUSE Linux 11.4. Using the latest versions of ssl and stunnel.

The ChangeLog entry: Version 4.46, 2011.11.04, urgency: LOW: * New features - Added Unix socket support (e.g. "connect = /var/run/stunnel/ socket"). - Added "verify = 4" mode to ignore CA chain and only verify peer certificate. - Removed the limit of 16 IP addresses for a single 'connect' option. - Removed the limit of 256 stunnel.conf sections in PTHREAD threading model. It is still not possible have more than 63 sections on WIN32 platform. http://msdn.microsoft.com/en-us/library/windows/desktop/ms740141(v=vs.85).a… * Optimizations - Reduced per-connection memory usage. - Performed a major refactoring of internal data structures. Extensive internal testing was performed, but some regression bugs are expected. * Bugfixes - Fixed WIN32 compilation with Mingw32. - Fixed non-blocking API emulation layer in UCONTEXT threading model. - Fixed signal handling in UCONTEXT threading model.

Hi, I'd like to user Stunnel with Haproxy on a Debian Squeeze server.

Why does verify=3 require the entire cert chain to be present in cafile?
by al_9x＠yahoo.com 03 Nov '11

If the leaf (server) cert is declared trusted (added to the cafile), there is no point in walking the trust chain.

[PATCH] Unix socket tunnelling
by Antoine Catton 02 Nov '11

02 Nov '11

Hi, I was looking for solution for tunneling a MySQL socket through encrypted IPv6. And I found this bunch of patches for stunnel <http://www.exceliance.fr/download/free/patches/stunnel/unix-sockets/>. Unfortunately, there's no patch for stunnel 4.44. So I rebased it in order to make it work (I attached it to this email). FYI, I’m not the author of this patch, I just adapted it for stunnel 4.44. The author seems to be this french company <http://www.exceliance.fr/en>. I just glanced over it, I didn't review it. Anyway, I think it would be a great thing to integrate it into stunnel in order to avoid rebasing the patch for every stunnel new version. Besides, it is a very useful feature. Integrating this patch would imply updating the documentation of stunnel configuration. As far as I know it add another general option “unix-sockets-dir” which is “/var/run/” by default. All the socket path must start by a slash, and this path will be appended to “unix-sockets-dir” option. Thank you. Regards, -- Antoine Catton Nexedi Intern
