Stunnel 4.05/4.07 Crash

28 Jan '05

Hi, I've initiated 11 stunnel processes in the same server. Each of the stunnel process has its own client certificate to communicate to application server. However after sometime of execution, the stunnel processes are crached (dying off) one by one. below is the last portion of my log (with debug level 7). I don't see any critical error in the log. Would appreciate if someone could highlight to me what cause the problem or anyone has similar experience. 2005.01.25 16:02:41 LOG7[2244:1424]: 0 server connects that finished 2005.01.25 16:02:41

Profiling STunnel

All, I need to do some performance profiling on STunnel. I assume gcov and gprof are the correct tools for this. Does anyone have any experience profiling STunnel? Any advice on how to do it properly would be appreciated. Thanks Mark Swann

Cannot find License.CM file
by Ranjit Mallick 26 Jan '05

26 Jan '05

Hi , I am new to stunnel , one of the previous develoeper has developed a application using Stunnel, essentially this app will work as a proxy to outside world and tunnel back to the remote server. On the server side the Stunnel has License.cm file and when ever I bring stunnel in CMD mode, it shows a message cannot find the License.cm file(even though it is there), Obviously the License file has expired or corrupted. How do I tell this tunnel.exe not to look for that file or how can I generate a license file(.cm)? Pls note that the tunnel has all the required files in it's directory tunnel.pem,tunnel.conf,ssleay32.dll,libeay32.dll,ssleay32.exp), pls help this is a show stopper and is effecting the client.Any leads or direction will be much appreciated. Thank you Ranjit __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

win32 stunnel - quiet service install
by joe smith 22 Jan '05

22 Jan '05

I would like to request the following feature be included in subsequent releases of stunnel. Cheers, Jeff Greetings, It would be great if while installing as a service on win32, there was an option to install quietly - i.e. only pop up a dialog box to the user if there's a problem. Any chance of somebody nice compiling me a binary that does this? :) M. -- Michael Brown {0x527670C0} | `One of the main causes of the fall of Systems Administrator | the Roman Empire was that, lacking zero, +1 519 888 7111 x2339 | they had no way to indicate successful michaelb at opentext.com | termination of their C programs.' - Firth --------------------------------- Do you Yahoo!?

stunnel and verify
by Brian Hirt 21 Jan '05

21 Jan '05

Hi, I've recently set up stunnel for a remote vnc connection, and it's working great. However, I would like to restrict access based on cert (only allow access a single public key), because nobody else should be accessing it besides my one machine. It seems what i want is to set verify = 3, but I'm using self-signed certs on my client, so verify = 3 fails. Is there some way to verify the client public key without doing the self signed test too? I'm sorry if this is a faq -- i searched the lists and read the faq and couldn't find anything. Thanks! (I'm running stunnel 4.04 on fedora1, and stunnel 4.04 on mac 10.3.7, installed via fink) my stunnel.conf is pretty simple. client conf is (sans connection info) client = yes cert = /sw/etc/stunnel/stunnel.pem chroot = /var/run/stunnel/ pid = /stunnel.pid setuid = stunnel setgid = stunnel server conf is: client = no cert = /etc/stunnel/stunnel.pem CApath = /etc/stunnel/clientdb chroot = /var/run/stunnel/ verify=3 pid = /stunnel.pid setuid = stunnel setgid = stunnel -------------------------------------------- MobyGames http://www.mobygames.com The world's largest and most comprehensive gaming database project

As it is already present in the services list, this has to fail. You can easily start and stop stunnel using the net command from a command line window: net start stunnel to start stunnel, or: net stop stunnel to shut it down again. You could make up a batch file to launch stunnel automatically for the time agent is running: --file runagent.cmd begin-- @echo off net stunnel start C:\Program Files\Agent!\Agent32.exe net stunnel stop --file runagent.cmd end-- Just edit the path for agent32.exe to match the path where you have Forté Agent installed, and you're done. P.S. I know net stunnel start can complain about that the service is already running, but that's just cosmetical and I was too lazy to implement logic to check if the service is already running ;) Best regards, Andre

Activating Stunnel After Exiting (Newbie)
by mhrtmhd94＠att.net 20 Jan '05

20 Jan '05

Hi. I just installed Stunnel, in order to be able to continue Agent as my mews reader. This works well. Based on the cautions on the website, I have decided to keep Stunnel active only when I am using Agent. Stunnel opens when I boot Windows - (XP Home Edition with Service Pack 2.) After close Agent, I right-click the Stunnel icon on the task bar and choose Exit. If I try to activate Stunnel later, by double-clicking its desktop icon, I am presented with an error window headed "stunnel 4.07 on Win32" with the following message: "Failed to create a new service". Looking at Properties on the desktop, I see that the Target is "C:\stunnel\stunnel-4.07.exe -install". This looks wrong, as it appears to be the option for initial installation of the program. I assume I need to change this, or discover another method of re-opening stunnel. As it stands now, I have to reboot to accomplish this. Any assistance will be appreciated. Thanks.

stunnel dropping connection with media wiki
by christopher＠baus.net 12 Jan '05

12 Jan '05

Hi all, I've been using stunnel with SMTP, IMAP, and HTTP with out a problem. Yesterday I installed media wiki on Fedora Core 2 w/ Apache. It works fine if I access it directly, but if I access the site via stunnel, the proxy drops connection. I was wondering if anybody else has seen this type of problem. I am tempted to dig into it, but I am honestly short on time right now. I think it might have something to do with the redirects that Media wiki uses, but that's just a wild guess.

I managed to compile and install stunnel 4.06 under Solaris 2.6. (BTW, I use here the word "managed" becuase it was not straightforward: the up-to-date version - 4.07 - wouldn't compile under Solaris.) My stunnel.conf file reads: cert=/opt/etc/stunnel/pop3.pem chroot = /opt/var/stunnel/ setuid = nobody setgid = nogroup pid = /stunnel.pid output=/var/log/stunnel.log client = no [spop3] accept = localhost:995 connect = localhost:110 [ssmtp] accept = localhost:465 connect = localhost:25 -------------- /opt/etc/stunnel/pop3.pem has been set up according the instructions at: http://www.freebsd.hello.pl/files/modules.php?name=News&file=article&sid=5 ...so I do hope it's OK ;-). Anyway, stunnel daemon works - what I get in stunnel.log reads: stunnel 4.06 on sparc-sun-solaris2.6 PTHREAD+POLL with OpenSSL 0.9.7e 25 Oct 2004 29 clients allowed (Date & time of the messages quoted above are omitted.)

Stunnel and DistCache Patch
by Kling, Kent M. 10 Jan '05

we have a RedHat 7.2 system and we are trying to apply the distcache_geoff.patch to enable distcache 1.4.5 with stunnel-4.04. We have run into a snag after the configure script is run and we attempt the "make", it complains that configure.in is missing. In step 2 is our "configure" line wrong? # make output: cd . && aclocal cd . && automake --gnu --include-deps Makefile cd . \ && CONFIG_FILES=Makefile CONFIG_HEADERS= /bin/sh ./config.status config.status: creating Makefile cd . && autoconf autoconf: configure.in: No such file or directory make: *** [configure] Error 1 Our work around is to change directory into the /usr/src/stunnel-4.04/src and run "make" from that directory to create our stunnel binary. Any idea why it won't work from the top directory. our stunnel source resides in /usr/src/stunnel-4.04, distcache_geoff.patch is in /usr/src and distcache-1.4.5 is in /usr/local/distcache-1.4.5.

Newbie trying to connect over a Microsoft Proxy
by Michael Blake 05 Jan '05

05 Jan '05

Hi All I'm a relative newbie to Stunnel, and am trying to set up a tunnel so I can Remote Desktop from work to my PC/server at home. I'm using versions 4.05 & 4.06 of the Windows binaries. A Microsoft Proxy Server v2.0 is used at work, and it proxies HTTP, Secure (is that SSL/port 443??), FTP and Gopher over port 800. I'm not sure if it proxies Socks, as there's no entry for it in Internet Explorer. I've tested the configuration and it works on my LAN, and it works from home when I enter my domain home (so my firewall is set up correctly). My config is as follows: #Client CAfile = stunnel.pem cert = stunnel.pem client = yes verify = 3 [rdp-80] accept = localhost:3390 connect = xxx.xxx.xxx.xxx:80 #Server CAfile = stunnel.pem cert = stunnel.pem client = yes verify = 3 [rdp-80] accept = 192.168.10.221:80 connect = 127.0.0.1:3389 Is there something I need to do to traverse this proxy? Any help would be greatly appreciated! Tks, Michael Blake IT Consultant | Headbyte Limited Tel: + 44 7909 844273 http://www.headbyte.co.uk

stunnel-4.07 on non-IPv6 systems

04 Jan '05

On systems which do not yet support IPv6 and do not have getnameinfo (for instance, Solaris 7), also NI_NUMERICHOST and NI_NUMERICSERV are usually undefined. In stunnel-4.07, this causes compilation of src/network.c to fail.

Port forwarding based on application type
by Konda Ankireddyapalli 03 Jan '05

03 Jan '05

Hello all, Can stunnel forward the traffic to different ports based on an application type as opposed to by port? If yes, how can it be configured? My need is that on the client side we have many applications that share a single outgoing port. On the server side I want to demultiplex the stunnel traffic coming in on a single port to multiple applications after decryption. Thanks in advance, Konda

A couple of patches against 4.06
by Peter Pentchev 31 Dec '04

31 Dec '04

Hi, First of all, thanks for writing and maintaining this great piece of software :) When I ported 4.06 to FreeBSD on Monday, there were three changes that needed to be made. One is the passing of -1, not -1000, to poll(2), which has already been discussed on this list (and which, by the way, is mandated by POSIX and the Single Unix Specification, as you can see at http://www.opengroup.org/onlinepubs/007908799/xsh/poll.html ) The other two can be seen in the patch below. The first one is related to the fact that EAI_NODATA is not present on all systems - it was actually obsoleted by the KAME implementation of IPv6 about an year ago. On some systems it is defined and has its own value - then stunnel builds just fine. On other systems it is not defined at all, while on yet other systems it is aliased to EAI_NONAME, so 'case EAI_NONAME' and 'case EAI_NODATA' would produce an error message from the compiler. Thus, the #ifdef and #if in the first chunk of the patch. This could not be done portably with a single statement, something like '#if defined(EAI_NODATA) && EAI_NODATA != EAI_NONAME', since there are some compilers that would barf on the second part if EAI_NODATA was not actually defined. The second chunk of the patch fixes getnameinfo() error reporting - just like with getaddrinfo(), getnameinfo() errors should be displayed using s_gai_strerror() instead of sockerror(). Keep up the good work!

using stunnel for smb networking
by David Bear 28 Dec '04

28 Dec '04

out of curiousity, has anyone been able to use stunnel as a cheap vpn for smb/cifs windows networks? We have a stupid firewall policy that blocks ALL port 139 traffic. Yes, thats good most of the time since microsoft rpc's are notoriously insecure. It does cause a problem when we have other units at other universities with different firewall policies however, so I was hoping to go around the different bureacracies and tunnel it myself. just curious. -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing"

The service gets registered correctly, when I try to start it, however, it seems not to find the stunnel.conf file. After downgrading to 4.04 everything works again. Any suggestions? Mat

Error when executing stunnel 4.06 Windows binaries as service
by Liron Newman 28 Dec '04

28 Dec '04

Hello, I'm trying to run the offical stunnel 4.06 Win32 binaries from stunnel.org as a service, but I get the following error: "The procedure entry point freeaddrinfo could not be located in the dynamic link library WS2_32.DLL" I looked it up a bit and it seems to have something to do with IPv6, but I don't use it.. stunnel 4.05 works fine as a service, and worked without a problem for months now. I'm using Win2k SP4 fully patched. Help? :)

Stunnel 4.06 released
by Michal Trojnara 25 Dec '04

25 Dec '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Here is the ChangeLog entry: Version 4.06, 2004.12.26, urgency: LOW: * New feature sponsored by SURFnet http://www.surfnet.nl/ - IPv6 support (to be enabled with ./configure --enable-ipv6). * New features - poll() support - no more FD_SETSIZE limit! - Multiple connect=host:port options are allowed in a single service section. Remote hosts are connected using round-robin algorithm. This feature is not compatible with delayed resolver. - New 'compression' option to enable compression. To use zlib algorithm you have to enable it when building OpenSSL library. - New 'engine' option to select a hardware engine. - New 'TIMEOUTconnect' option with 10 seconds default added. - stunnel3 perl script to emulate version 3.x command line options. - French manual updated by Bernard Choppy <choppy AT free POINT fr>. - A watchdog to detect transfer() infinite loops added. - Configuration file comment character changed from '#' to ';'. '#' will still be recognized to keep compatibility. - MT-safe getaddrinfo() and getnameinfo() are used where available to get better performance on resolver calls. - Automake upgraded from 1.4-p4 to 1.7.9. * Bugfixes - log() changed to s_log() to avoid conflicts on some systems. - Common CRIT_INET critical section introduced instead of separate CRIT_NTOA and CRIT_RESOLVER to avoid potential problems with libwrap (TCP Wrappers) library. - CreateThread() finally replaced with _beginthread() on Win32. - make install creates $(localstatedir)/stunnel. $(localstatedir)/stunnel/dev/zero is also created on Solaris. - Race condition with client session cache fixed. - Other minor bugfixes. * Release notes - Win32 port requires Winsock2 to work. Some Win95 systems may need a free update from Microsoft. http://www.microsoft.com/windows95/downloads/ - Default is *not* to use IPv6 '::' for accept and '::1' for connect. For example to accept pop3s on IPv6 you could use: 'accept = :::995'. I hope the new syntax is clear enough.

Fwd: [stunnel-users] stunnel 'options' section of config file
by Justin Miller 21 Dec '04

21 Dec '04

I understand the security concerns... I was just trying different protocols because I was receiving weird error messages with some https proxies (using the mathias wald patch) about wrong version numbers, etc. Googling it seemed to indicate that enabling/disabling ssl2/ssl3/tls1 could do the trick. However, I can't even get 'openssl s_client...' to yield a successful connection with some of these proxies. Can stunnel handle incoming http or socks proxy requests/connections? If not, will you ever support that? For instance I want stunnel listening on a local port 8080 and connect to a remote https proxy, and I set the HTTP proxy server in gaim to localhost:8080. -Justin On Tue, 21 Dec 2004 15:20:19 +0100, Michal Trojnara <Michal.Trojnara(a)mobi-com.net> wrote: > Justin Miller wrote: > > So all looks well ang good...

stunnel 'options' section of config file
by Justin Miller 21 Dec '04

21 Dec '04

Is it just me, or does stunnel not seem to obey the ssl 'options' setting in the config file? I have the lines: options = TLS_ROLLBACK_BUG options = NO_TLSv1 options = NO_SSLv3 And when I start stunnel, the output is: 2004.12.20 07:47:46 LOG7[9981:1024]: Configuration SSL options: 0x06800000 2004.12.20 07:47:46 LOG7[9981:1024]: SSL options set: 0x06800000 So all looks well ang good... But then when it sends the client hello message, one would expect an ssl2 message, but we get the following output: 2004.12.20 07:47:51 LOG7[9984:1026]: SSL state (connect): SSLv3 write client hello A 2004.12.20 07:47:51 LOG7[9984:1026]: waitforsocket: FD=10, DIR=read 2004.12.20 07:47:51 LOG7[9984:1026]: waitforsocket: ok 2004.12.20 07:47:51 LOG7[9984:1026]: SSL alert (write): fatal: handshake failure 2004.12.20 07:47:51 LOG3[9984:1026]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number That first line seems to indicate that it's still sending a v3 message. Is this actually what's happening?

stunnel 4.06 and compression
by saruman 20 Dec '04

Hello. Is there any way to get the beta version of stunnel 4.06 (I've seen in this list that it must support compression)? Or if I can't get new version - can I somehow enable compression in stunnel 4.05? Oleg Ivanov

Problem with huge stunnel.conf
by CIM Massy 20 Dec '04

20 Dec '04

Hi everyone ! I have 900 (W2K) machines that I have to securely log onto. I chose to use both of Ultr@VNC and RealVNC 4.0 (running on ports 5900 & 5901). And I chose to use STunnel 4.05 on W2K to secure the sockets. On my admin PC, Stunnel.conf looks like /*******************************/ #cert stuff [ultravnc0101] accept = 127.0.1.1:5900 connect = PC0101:5700 [realvnc0101] accept = 127.0.1.1:5901 connect = PC0101:5701 ... [ultravnc1000] accept = 127.0.10.0:5900 connect = PC1000:5700 [realvnc1000] accept = 127.0.10.0:5901 connect = PC1000:5701 /*******************************/ And it does only work for the first 31 pairs of "services". (No Authentification issues.) When I move the "PC0101" services to the end of the file it will not work anymore, whereas it does when it's first in the .conf file. I guess having 1800 services is not necessarily the way Stunnel is meant to work... Is it a known issue ? I haven't been able to find any infos on it in newsgroups or with Google. It does not seem to be a W2K problem since it works with the 64 first services. If anyone knows a workaround... Thanks for your help, Reagrds Philippe HAMEAU

UDP applications

20 Dec '04

Hi all, Is there any roadmap for Stunnel to support UDP applications? Cant a simple UDP forwarder (with proper buffering to ensure a tcp-like stream of data) do the job? May be this topic is discussed and brainstormed before. I couldnot find any relevant details about this in the archives. Thanks and Regards, Paul

Need help: verification of client and server certificates
by Mike_Stunnel 20 Dec '04

20 Dec '04

For my Stunnel server, I'm using Windows ME, OpenSSL 0.9.7e and Stunnel 4.05. I've create my own Certificate Authority on my server and created and signed a server and multiple client certificates for Stunnel. I plan to use Stunnel to secure my VNC connections to my PC - to encrypt the traffic and to validate the clients. On the server side: ------------------- I want to limit connections to my Stunnel server to only those Stunnel clients that present a client certificate that I already have a copy of on my server. And I want Stunnel server to only recognize my own Certificate Authority as a valid CA for the clients' certificates. Is this possible? What options do I need to specify in the Stunnel server configuration file to make this work? The documentation is confusing to me - for example, do I use CAfile or CApath to point Stunnel to the the CA certificate? Will Stunnel recognize other CAs as trusted, if their certificates have been loaded by other programs like a browsers or mail reader? Etcetera .. On the client side: ------------------- As with the server, I want my Stunnel client to only recognize my own CA as trusted. And I want it to validate the server certificate as thoroughly as possible. Is that verify level 3? I need the CA certificate on my client, but do I use CAfile or CAcert in the config file to point to it? Do I need a copy of the server certificate on my client so that the client can verify the server's certificate? I'm so confused! I've read the FAQ and Related links on stunnel.org and also the past 4 months' mailing list digests but I'm still not clear on the certificate verification process. or all the options in the configuration file.

I have been working/using stunnel for quite sometime... I am using it along with SOcks. So was wondering is there anyone who is already working on providing socks (v4 or v5) support to existing stunnel? Also is there any1 else who is also requires socks functionality in stunnel? Thanks and Regards, Paul.
