Stunnel Configure Warning
by G J Piper 21 Oct '05

21 Oct '05

I was upgrading my Stunnel 4.11 to 4.13 when I saw this in the config check and decided to post it to see if I should continue installing... the config told me (obvoiously) to post this message... heh: > checking ucontext.h usability... no > checking ucontext.h presence... yes > configure: WARNING: ucontext.h: present but cannot be compiled > configure: WARNING: ucontext.h: check for missing prerequisite headers? > configure: WARNING: ucontext.h: see the Autoconf documentation > configure: WARNING: ucontext.h: section "Present But Cannot Be Compiled" > configure: WARNING: ucontext.h: proceeding with the preprocessor's result > configure: WARNING: ucontext.h: in the future, the compiler will take precedence > configure: WARNING: ## ---------------------------------- ## > configure: WARNING: ## Report this to the stunnel lists. ## > configure: WARNING: ## ---------------------------------- ## > checking for ucontext.h... yes > checking pthread.h usability... yes > checking pthread.h presence... yes > checking for pthread.h... yes What can be done? ~ Greg

stunnel 4.13 released
by Michal Trojnara 21 Oct '05

21 Oct '05

Version 4.13, 2005.10.21, urgency: MEDIUM: * DLLs for OpenSSL 0.9.7i included because protection faults were reported in 0.9.8 and 0.9.8a. * New features - Libwrap code is executed as a separate process (no more delays due to a global and potentially long critical section). * Bugfixes - Problem with zombies in UCONTEXT threading fixed. - Workaround for non-standard makecontext() uc_stack.ss_sp parameter semantics on SGI IRIX. - Protection fault in signals handling on IRIX fixed. - Problem finding pthread library on AIX fixed. - size_t printf() fixed in stack_info() (the previous fix didn't work). - socklen_t is used instead of int where required. Homepage: http://stunnel.mirt.net/ sha1sum for stunnel-4.13.tar.gz: 4cb8e162e6cd4b4a966d601d1c890df2c2ee198f Best regards, Mike

smtp and tls
by Andy Cravens 21 Oct '05

21 Oct '05

Does stunnel support using TLS with SMTP? My SMTP server requires TLS but my client does not support it. Unfortunately, my SMTP server does not support SMTP over SSL so my only choice is to use TLS. I've seen some old threads concerning a patch to stunnel 3.x to do TLS but I read it was not a good solution. Does anybody have any information or opinions on this?

ECC-enabled version of Stunnel

Hello, I want to use a ECC-certificate for stunnel.pem, but it doesn't work. Can anybody help me, what I have to do, to use Elliptique Curve cryptography certificates in Stunnel? Is it still possible or not?

stunnel silently dies
by Uffe Vedenbrant 18 Oct '05

18 Oct '05

Hi! After using stunnel on several freebsd boxes i decided to try it out on my mailserver.. Unfortunately it silently died after first connection.. ( and with exitcode=0 ) debug = 7 Nothing more in the log than startup + a line about a incomming connection on port 9143.. ( where i put my incomming imap ) Nothing in any log on the box.. Ok.. It might be my openssl freebsd version or stunnel version so i started to upgrade everything.. Freebsd 4.4 -> 4.11 stunnel 4.05 -> 4.11 etc.. Well did it work.. Nop..;-) Finally i found out after tryin ktrace that the problem was that the tcpwrapper code killed me.. That's ok but there where no logging at all that the tcpwrapper silently decided that i was comming from a blocked host.. It's up now without tcpwrapper enabled and works perfect..;-) Is there any possibility to have stunnel to say something about tcpwrapper problems..;-) And not just die..;-) Regards /Uffe

client and server together?
by Sholund, Mark D, GVSOL 18 Oct '05

18 Oct '05

I have a situation in which I have a client system, a middle-tier application server, and a backend database. The middle-tier takes info from the client and sends requests to the database, in other words the middle-tier has to act as both a client and a server in different parts of a transaction. Is it necessary that I run two instances of stunnel, one with an stunnel-client.conf wherein client=yes and another instance with stunnel-server.conf wherein client=no or is it possible to configure a single stunnel to do this? I would guess it would be kind of like having "client=yes|no" at the service level; this is not an option as far as I can see from the man page for 4.12 but I figured I could at least ask.

Hello I've got problem with vnc over stunnel, stunnel on client computer crashes all the time. I did all configuration according to information at http://www.securityfocus.com/infocus/1677. Stunnel v 4.12, VNC version 4.1.1, all firewalls off, all computers in the same LAN. Tried on Windows XP SP2 and Windows 2000, on both of them there was a crash. All necessery (at least I think so) information are here: http://users.vlo.ids.gda.pl/~piotr/client.txt http://users.vlo.ids.gda.pl/~piotr/server.txt http://users.vlo.ids.gda.pl/~piotr/windows.txt Thank you in advance

Should I generate certifcates again? Meantime, I did configure it on my Ubuntu 10 X box, and manage to connect with server, so I guess server configuration is ok. Thanks for help. Best regards.

IMAP TLS support in stunnel 4?
by George Hartzell 12 Oct '05

12 Oct '05

Hi All, I'd like to put stunnel in front of dbmail-imap and dbmail-pop, since they don't offer any encryption. I understand I can just do straight ssl connections, but would like [prefer] to support TLS. I've found patches to the stunnel 3 series that implement TLS for IMAP, but haven't found any for version 4. Has someone implemented it for 4? Is there a technical or political reason/problem, or just not enough round-tuits? Thanks, g.

404 File Not Found when accessing webservice using STunnel (works fine without STunnel)

"stunnel 4.08 on x86-pc-mingw32-gnu WIN32+IPv6 with OpenSSL 0.9.7e 25 Oct 2004" Hi, this is my first try with both SSL & STunnel, so please excuse me for any missunderstandings a.s.o. I have problems running a STunnel in client-mode agains a SSL webservice. Our application does not support clientside-certificates, so i want to use STunnel to handle the SSL connection. For now, our webservice-provider has disabled the need for client-certificates (to help us narrow our problem down) But it still dont work. As a first step, i access whe webservice default-page through IE-Explorer. https://<ip>:3001/<path> and i am presented with the default-webpage. As i second step, i start stunnel with following .conf verify = 2 CApath = <path where i have saved all certificates as .pem:s with <hash>.0 filenames, from the direct-access example with explorer above> debug = 7 client = yes [https] accept = 127.0.0.1:3000 connect = <ip>:3001 TIMEOUTclose = 0 and try to access http://127.0.0.1:3000/<path> but i get: HTTP 404 File Not found. I have tried the same approach against a microsoft webservice at: https://test.uddi.microsoft.com/extension.asmx Without any problems. 1. I see no errors in the log, as i understand it (se below) can any one else with a more skilled eye see any problem ? 2. Our webservice-provider has an invalid hostname in its certificate (no public hostname, just IP during testing, but server certificate state www.fora.se) might that cause a problem ? (i have tried localy with invalid hostname in certificate without any problem though) 3. Is it possible to enable/disable verification of hostname in STunnel ? (as i understand it, the "verify" option in the STunnel.conf concerns the whole certificate-validation-process, and not just the hostname validation ?) 4. Could the problem be a config-issue on the webservice-provider end ? Im not sure, as it works with IE-Explorer, but not through STunnel ? 5. Any clue on where to look would be greatly apriciated, i have been working with this for a week, and i have been able to use STunnel both as server & client, with & without client-certs against everything i have tested localy and public (tried between diffrent home-made applications, on a local webserver, against verisign website a.s.o.) and everything works fine, except where i need it to work (against our webservice-provider).

STUNNEL and Windows 98 Second Edition

08 Oct '05

I've installed STUNNEL on a Win 98 SE machine. Connections die after a few or a few hundred bytes. Any ideas? Thanks, Dave. ----------------------------------- David T. Ashley (dta(a)e3ft.com) Thousand Feet Consulting, LLC

UID/GID/Permissions Issue
by David T. Ashley 08 Oct '05

08 Oct '05

I've installed STUNNEL, works great, etc. etc. etc. Just one thing is a mystery .... The daemon definitely runs with UID "stunnel" (as I set it up), but still somehow it is able to grab its own keys and cert, as well as the client cert, which I set with root-only access. How is that possible? Does it buffer these things during startup (as root) before it sets UID/GID to stunnel, or am I missing something? Thanks. ----------------------------------- David T.

stunnel-4.12 Solaris 9 libwrap compile problem
by John Christian 07 Oct '05

07 Oct '05

Hi gurus... I'm setting up a centralized log server for all of my Solaris 9 hosts. Kim's article at http://www.sun.com/bigadmin/features/articles/syslog_ng.html is providing much of the guidence. I plan to use syslog-ng, but would like to have stunnel in place first. http://www.sunfreeware.com does not have a pre-rolled stunnel for Solaris 9. I'm receiving the error below when trying to compile stunnel-4.12 on Solaris 9. Can you offer any tips on overcoming the stunnelcompile error below? ERROR: [snip] gcc -g -O2 -Wall -Wshadow -Wcast-align -Wpointer-arith -I/usr/local/ssl/include -o stunnel client.o log.o options.o protocol.o network.o resolver.o ssl.o sthreads.o stunnel.o pty.o -lz -lsocket -lnsl -L/usr/local/ssl/lib -lssl -lcrypto -lwrap Undefined first referenced symbol in file allow_severity /usr/sfw/lib/libwrap.so deny_severity /usr/sfw/lib/libwrap.so ld: fatal: Symbol referencing errors.

My environment variable LD_LIBRARY_PATH is: LD_LIBRARY_PATH=/usr/openwin/lib:/usr/dt/lib:/usr/local/lib:/usr/local/ssl/lib:/usr/sfw/lib Thanks for taking the time to share any direct solutions or hints that will help me find a solution. -John __________________________________ Yahoo!

Help With Verify = 3
by David T. Ashley 07 Oct '05

07 Oct '05

Hi, I installed Stunnel 4.12 on a Linux box, and am attempting to use it to secure SMTP e-mail injection from Windows machines. I have everything working, and I have a Windows Stunnel client which will inject mail into a Linux Stunnel server over TCP Port 465. However, I've been unable to find the right combination of verification settings to cause the server to refuse connections from clients without the right certificates. Right now, I'm able to inject mail if the client has ANY certificate. Is there any tutorial on how to generate the keys, .PEM files, and the Stunnel settings to have the behavior where only MY clients can inject mail? Thanks and best regards, Dave Ashley.

stunnel and logrotate
by Bohdan Linda 06 Oct '05

06 Oct '05

Hello, I have noticed that by sending -HUP signal to stunnel causes daemon to exit. The problem is when stunnel is logging to a file and the file was recreated (i.e. by logrotate). I have blindly configured logrotate to send -HUP to the stunnel after the logs are rotated and awaited 'common-habbit' functionality: re-read configuration and refresh file handles. But I was supprised: xxxx@yyyyy:/var/log# more stunnel.log.1 2005.09.27 14:07:51 LOG5[23244:3084273344]: stunnel 4.07 on xxxxxxxxxxxxxxx 2005.09.27 14:07:51 LOG5[23244:3084273344]: 500 clients allowed 2005.10.02 04:40:03 LOG3[23245:3084273344]: Received signal 1; terminating Apparently messages are going to the 'old' filehandle and stunnel exits. Is there any workaround to this except: 1) hard restarting stunnel 2) putting stunnel in inetd Thank you, Bohdan

Stunnel 4.12 won't work with Openssl 0.98
by Luca G. 05 Oct '05

05 Oct '05

Hi I upgraded yesterday from stunnel 4.11 to 4.12, and i had a few problems... Basically I have been unable to use latest libeay32.dll and libssl32.dll versions (the one that comes with stunnel's installation file). I use stunnel to tunnel a thightvnc connection from my windows xp sp2 workstation to a couple of windows 2000 server machine on the opposite side of the building. At the moment i'm keeping 0.98 files on the server machines, 0.97f on my client and it works These are my stunnel.conf files -----------------------------------client CAfile = CAcert.pem CApath = certificates cert = client.pem client = yes verify = 3 debug = 7 output = stunnel.log [vnc] accept = 127.0.0.1:5900 connect = 192.168.1.252:443 [vnc2] accept = 127.0.0.1:5899 connect =

4.12 Broken?
by G J Piper 04 Oct '05

04 Oct '05

The new Stunnel Version 4.12 doesn't work well with POPs mail retrieval on my system. Reverting back to 4.11 fixes it perfectly. With 4.12, various emails wouldn't come through, got random timeouts, LONG email retrieval times mainly. Sometimes an email would be impossible to retrieve from the spool file. Running Stunnel with default parameters. Standalone I believe POPs runs off xinetd. % uname -a FreeBSD pipercomputerservices.net 4.4-RELEASE FreeBSD 4.4-RELEASE #0: Wed Aug 28 19:41:18 GMT 2002 root@osbuilder:/usr/src/sys/compile/SERVER i386 % gcc -v Using builtin specs. gcc version 2.95.3 20010315 (release) [FreeBSD] % openssl version OpenSSL 0.9.6e 30 Jul 2002 % stunnel -version stunnel 4.11 on i386-unknown-freebsd4.4 PTHREAD+POLL+IPv4+LIBWRAP with OpenSSL 0.9.6e 30 Jul 2002 Global options cert = /usr/local/etc/stunnel/stunnel.pem ciphers = ALL:!ADH:+RC4:@STRENGTH debug = 5 key = /usr/local/etc/stunnel/stunnel.pem pid = /usr/local/var/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes session = 300 seconds verify = none Service-level options TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds

Help: Remote desktop connection crashes Stunnel
by Jonathan Bell 04 Oct '05

04 Oct '05

In an attempt to get remote desktop set up over SSL tunneling with compression, I have installed stunnel on my Windows XP Professional SP2 machine and created a "portable" stunnel/config/dll zip that just contains the essentials to create a pre-configured tunnel. Here are the two config files: Server -------------------------------- ; Sample stunnel configuration file by Michal Trojnara 2002-2005 ; 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 compression = zlib ; Some debugging stuff useful for troubleshooting debug = 6 output = G:\Stunnel Logs\stunnel.log taskbar = no ; Use it for client mode client = no ; Service-level configuration [remote-desktop] accept = 9833 connect = 127.0.0.1:3389 --------------------------------- Client --------------------------------- ; Sample stunnel configuration file by Michal Trojnara 2002-2005 ; Some options used here may not be adequate for your particular configuration ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 compression = zlib ; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log taskbar = yes ; Use it for client mode client = yes ; Service-level configuration [remote-desktop] accept = 127.0.0.1:6389 connect = my.host.name:9833 ---------------------------------- The procedure I used was as follows - start Stunnel on the host, run upstairs with the zipped "portable" stunnel on a USB drive, run stunnel on the other PC, also running XP Pro SP2. Start->run->mstsc, enter 127.0.0.1:6389 and all that happens is that stunnel instantly crashes then Remote Desktop times out. What am I doing wrong?

Dual Instance of Stunnel Service on W2K
by Mundy Jennifer 04 Oct '05

04 Oct '05

Am new to stunnel and in need of some help. I have W2K box that has Stunnel installed as a service. Upon startup, it starts the service and uses the default stunnel.conf file. I would like to install a second Stunnel service and call a custom .conf service. Is this possible? I've read thru the documentation but haven't come across anything about a second service. We're running v4.05. I know I can get a second instance running via cmd line/batch file, but need the second instance to startup automatically so it can be monitored as well as other things.

SSL_GET_NEW_SESSION:ssl session id callback failed
by DoJo 04 Oct '05

Hi There, We have run into "SSL_GET_NEW_SESSION:ssl session id callback failed" error. Can anyone describe what it means? I didn't find any information about it. We'd like to use stunnel to secure Oracle SQL*Net communication. HP-UX server communicates with Win32 clients. We use stunnel standalone not from inetd. Any help would be appreciated.

stunnel4 user + permissions
by nick.hoffman＠altcall.com 04 Oct '05

04 Oct '05

Hey guys, I've been using stunnel for a while and it's great. I've noticed something that doesn't make much sense to me though, so I was wondering if you might be able to shed some light. Stunnel runs as user:group stunnel4:stunnel4. The server reads client certs (for verify = 3) from /etc/stunnel/certs/ which is chown'd root:ssl-certs and chmod'd 750. The client PEMs in that directory have the same ownership and permissions. User stunnel4 is in the ssl-certs group. When a client connects, the server is unable to read from /etc/stunnel/certs/. If I change the ownership of the directory to root:stunnel4 though, everything works. Any idea why this occurs? Cheers, Nick
