Connecting via rtmps to Red5 server
by David Schulberg 25 Apr '07

25 Apr '07

Hi, I have been led to stunnel as the way to get a Flash application to communicate securely with Red5 server. Red5 doesn't directly support ssl connectivity but using rtmps protocol (rtmp tunnelled via https) clients should be able to connect to Red5 if stunnel handles the encrypted traffic on port 443 and passes unencrypted communications back and forth to the Red5 on a port it expects to receive rtmp communication.. (refer http://www.adobe.com/devnet/flashcom/articles/firewalls_proxy04.html) The log file I get when I attempt to talk rtmps is shown below 2007.04.25 18:19:04 LOG7[3932:3384]: New thread created 2007.04.25 18:19:04 LOG7[3932:3664]: https started 2007.04.25 18:19:04 LOG7[3932:3664]: FD 224 in non-blocking mode 2007.04.25 18:19:04 LOG7[3932:3664]: TCP_NODELAY option set on local socket 2007.04.25 18:19:04 LOG5[3932:3664]: https accepted connection from 127.0.0.1:1249 2007.04.25 18:19:04 LOG7[3932:3664]: FD 248 in non-blocking mode 2007.04.25 18:19:04 LOG7[3932:3664]: https connecting 127.0.0.1:1935 2007.04.25 18:19:04 LOG7[3932:3664]: connect_wait: waiting 10 seconds 2007.04.25 18:19:04 LOG7[3932:3664]: connect_wait: connected 2007.04.25 18:19:04 LOG5[3932:3664]: https connected remote server from 127.0.0.1:1250 2007.04.25 18:19:04 LOG7[3932:3664]: Remote FD=248 initialized 2007.04.25 18:19:04 LOG7[3932:3664]: TCP_NODELAY option set on remote socket 2007.04.25 18:19:04 LOG7[3932:3664]: SSL state (connect): before/connect initialization 2007.04.25 18:19:04 LOG7[3932:3664]: SSL state (connect): SSLv3 write client hello A 2007.04.25 18:24:04 LOG6[3932:3664]: init_ssl: s_poll_wait timeout 2007.04.25 18:24:04 LOG5[3932:3664]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2007.04.25 18:24:04 LOG7[3932:3664]: https finished (0 left) The stunnel.conf file has the following settings that pertain specifically to this situation client = yes [https] accept = 443 connect = 1935 What I seem to see (according to the logfile) is that an ssl connection is successfully established but no subsequent communication takes place after the connection has been made. At this point my Flash application doesn't send any messages via the ssl connection which seems to implicate my client as being the source of my problem. I would appreciate any advice on how I can best investigate this whole situation to resolve the issue. Regards, David Schulberg email: davids(a)evertech.com.au

Using Client Authentication
by Ravi Gowda 16 Apr '07

16 Apr '07

Hi All, I am trying to have a setup where stunnel acts as a client to a server which requires client-Authentication. This is the snapshot of my stunnel.conf # Sample stunnel configuration file # Copyright by Michal Trojnara 2002 setuid = nobody setgid = nobody output = /etc/stunnel/out cert = /etc/stunnel/rtca-client.pem key = /etc/stunnel/rtca-client.ky # Authentication stuff verify = 2 # don't forget about c_rehash CApath # it is located inside chroot jail: #CApath = /certs # or simply use CAfile instead: CAfile = /etc/stunnel/rtca.pem ciphers = DHE-RSA-AES256-SHA:DHE-DSS-AES256-SHA:AES256-SHA:EDH-RSA-DES-CBC3-SHA:EDH-DSS-DES-CBC3-SHA:DES-CBC3-SHA:DES-CBC3-MD5:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA:AES128-SHA:IDEA-CBC-SHA:IDEA-CBC-MD5:RC2-CBC-MD5:DHE-DSS-RC4-SHA:RC4-SHA:RC4-MD5:RC4-MD5:RC4-64-MD5:EXP1024-DHE-DSS-DES-CBC-SHA:EXP1024-DES-CBC-SHA:EXP1024-RC2-CBC-MD5:EDH-RSA-DES-CBC-SHA:EDH-DSS-DES-CBC-SHA:DES-CBC-SHA:DES-CBC-MD5:EXP1024-DHE-DSS-RC4-SHA:EXP1024-RC4-SHA:EXP1024-RC4-MD5:EXP-EDH-RSA-DES-CBC-SHA:EXP-EDH-DSS-DES-CBC-SHA:EXP-DES-CBC-SHA:EXP-RC2-CBC-MD5:EXP-RC2-CBC-MD5:EXP-RC4-MD5:EXP-RC4-MD5 # Some debugging stuff debug = 7 output = /etc/stunnel/stunnel.log # Use it for client mode client = yes when I try to connect to the server, I am seeing that Stunnel is sending an empty certificate..which is making my server to reject connections. Can someone please help me out?? Thanks in Advance Ravi Gowda

Simply concatenate the certificates (in PEM format) in the file specified by "cert = ..." and supply the key of your server certificate either in the same file or in the file specified by "key = ...".

stunnel-4.20 crash on AIX
by Peter O'Gorman 12 Apr '07

12 Apr '07

Hi, We built stunnel-4.20 on solaris, hpux, aix, tru64. irix and various linux hosts, and it works fine everywhere except hpux10.20 and aix. stunnel crashes with similar backtraces on AIX-4.3,5.1,5.2 and 5.3, not on the first client connect (using stunnel client=yes, connecting to s secure daytime server on another host, because everyone needs a secure daytime server :-p) but on the second connection. We have not tried server side yet, I assume results are similar. The backtrace looks like this: GDB: Program terminated with signal 11, Segmentation fault. #0 0xd0126b1c in _sigsetmask () from /usr/lib/libpthreads.a(shr_xpg5.o) (gdb) bt #0 0xd0126b1c in _sigsetmask () from /usr/lib/libpthreads.a(shr_xpg5.o) #1 0xd0127e5c in _p_sigaction () from /usr/lib/libpthreads.a(shr_xpg5.o) #2 0xd0315544 in sigaction () from /usr/lib/libc.a(shr.o) #3 0xd038beac in signal () from /usr/lib/libc.a(shr.o) #4 0x10006200 in sigchld_handler (sig=0) at network.c:350 #5 0x00004378 in ??

Line 350 of network.c says: signal(SIGCHLD, sigchld_handler); And that is in the signal handler, it seems like a normal thing to do, and I have no idea why, on AIX, it crashes. putting an #ifndef _AIX #endif around the signal() call "fixes" the crash, alternatively setting SIGCHLD to SIG_IGN on AIX "fixes" it, but I don't think that either solution is correct. I don't believe the signal handler will get called again as we do not reset the signal. (tests that assumtion and finds answer to riddle) Okay, problem identified. The signal_handler is being called repeatedly, causing an infinite loop that can only end in a crash. According to the AIX signal man page: The signal in libc.a does not set the SA_RESTART flag. It sets the signal mask to the signal whose action is being specified, and sets flags to SA_OLDSTYLE. The Berkeley Software Distribution (BSD) version of signal sets the SA_RESTART flag and preserves the current settings of the signal mask and flags. The BSD version can be used by compiling with the Berkeley Compatibility Library (libbsd.a). And indeed, no patches are required if I add -lbsd. Another solution would probably be to use sigaction if it is available. Meanwhile, please find attached a patch to add -lbsd on aix. Thanks for bearing with me while I figured this out :-) Peter

Setting up chain certificates on Stunnel.
by Satyajit Das 12 Apr '07

12 Apr '07

Hi , I am using stunnel as a wrapper to provide SSL functionalities for my server. Right now I am having problems setting up chained certificates on stunnel. My Problem -> My server certificate > signed by intermediate CA > signed by Verisign CA I have the Verisign certificate on my clients trusted root CAs, however I am not able to get the SSL communication through. I believe this is because stunnel should send all the three certificates for authentication and I couldnt configure stunnel to send across all the three certificates. Can anybody please help install all these certificates on stunnel. Thanks in advance, Satyajit

forcing checking of local certificates every time
by san san 11 Apr '07

11 Apr '07

Hi, I am using stunnel with verify option with value 3. In value 3 the authentication is carried out using the local trusted certificates. I think stunnel does not check the local trusted certificates directory each and every time. If the connection has already been established then it does not check local trusted certificates , connection can be established using the certificates in cache. Is it possible to force to check the local trusted certificates every time. Regards

stunnel work with NAT
by atsushi kataoka 11 Apr '07

11 Apr '07

I have one question , does stunnel work with NAT ? I will explain the architecture There are some 10.0.0.XXXX machines and some are 192.0.0.XXXX machines. They are connected to each other via Router which does NAT. My VNC servers are installed on 10.0.0.XXXX and vnc clients on 192.0.0.XXXX I am not able to do the vnc from client to server. Now I want to encrypt the VNC traffic , can stunnel work with NAT? A Kataoka

running concurrent stunnel instances
by John Taylor 10 Apr '07

10 Apr '07

Greetings, I am running rsync through stunnel 4.20. Each end is a Dell dual cpu, dual core Xeon (each core with hyper-threading) 8 gigs of memory, running Win 2003 Server. The disks are 10K RPM Ultra-320 drives that use hardware raid-5. Right now, I have anywhere between 5 and 8 Scheduled Tasks running at the same time. The reason for this is that the backups need to run in parallel in order to finish within the 15 hour time window. Although I am not certain about an exact number, I believe I would be transferring about 300-400 gig of data each time. Even though I have a gigabit connection between the two servers, I am only seeing 5-6% network utilization. When running the same rsync batch file without stunnel encryption, the throughput was much higher. I would like to see about increasing my throughput with stunnel encryption running. I don't expect it to be as fast as running without stunnel, but I still think I should be able to do better than 5-6% throughput. I am also running a enhanced version of rsync that does not have any issues with NTFS disk fragmentation, since it preallocates the files to the final size before writing. I think the bottleneck is the CPU. To test out this theory, I would like to have multiple copies of the stunnel.exe running, each using their own config file and own port numbers. I don't think the problem is with rsync because it spawns a new process for each connection. Thus, the multiple rsync.exe processes get the advantage of running on top of multiple cores. This is not the case with stunnel.exe. It only uses 1 process, but 8 threads. I am hoping that multiple stunnel.exe instances will fix the bottleneck because each stunnel.exe process could then be running on it's own core. How can I accomplish this? Also, what is the fastest encryption cipher that stills has good security, over 64 bit, preferably at least 128 bit. Any help would be greatly appreciated.

stunnel as ssh client and self signed certificates
by san san 07 Apr '07

07 Apr '07

Hi, I was planning to use stunnel for my rdp based product. I have several trivial doubts,but since i would be using the same in my product. I would like to know following 1.Actually i want to use stunnel in the same way as ssh i.e Client authentication only , i don't want server authentication at all in my client. So it is possible to not check any server certificate from client side. If i will be using client certificate 2.Is it possible to use self-signed certificate ? I am aware of the drawbacks of using self-signed certificates but because of some inevitable reason i have to use self-signed certificates. I am sorry for my poor knowledge. Regards

Hi! I want to use STunnel to secure my IMAP connections to my mail server. It works fine but from now on the mail server shows 127.0.0.1 for the open imap client connections. Is there a way to get STunnel forward the real IP or is this impossible? Thanks, Konrad

Simple Stunnel Question
by mdpeters 28 Mar '07

28 Mar '07

My goal is to have a web server transfer MySQL data via an AES tunnel to a MySQL database server with an added encryption card. Both systems have the same SSL and Stunnel software installed. My web servers database seems to be functioning as normal. I would like to verify that what I have is complete and effective. It is not apparent to me if I have finished construction or how to verify this works like I want it to. I'm not sure how I would verify that Stunnel is being used?

Stunnel support or OpenSSL in FIPS mode
by George Henson 26 Mar '07

26 Mar '07

All, Are there any current plans to include FIPS complaint mode in stunnel? I have asked some of my peers on other US Government projects and they indicated this would be a help to them as well. Looking at the users guide from the OpenSSL site (http://www.openssl.org/docs/fips/UserGuide-1.1.1.pdf) it would not appear to be a great amount of effort to make a stunnel that functions in a FIPS complaint mode. Attached I have included the patch I have created (with some help from friends). It does not do the final linking correctly as I am not very good with autmake. Please let me know what you think. Thank you George diff -u -r @stunnel-4.20/configure.ac stunnel-4.20/configure.ac --- @stunnel-4.20/configure.ac 2006-11-11 09:58:01.000000000 -0500 +++ stunnel-4.20/configure.ac 2007-03-26 18:35:09.000000000 -0400 @@ -260,6 +260,51 @@ CFLAGS="$CFLAGS -I$ssldir/include" LIBS="$LIBS -L$ssldir/lib -lssl -lcrypto" +AC_ARG_WITH(fips, + [ --with-fips Enable OpenSSL FIPS mode], + [ + if test "x$withval" != "xno" ; then + INCLUDES="=l$ssldir/include" + AC_CACHE_CHECK([for FIPS mode], ac_cv_fips, [ + AC_TRY_COMPILE( + [ #include <openssl/fips.h> ], + [ FIPS_mode_set(1); ], + [ ac_cv_fips="yes" ], + [ ac_cv_fips="no" ] + ) + ]) + fi + ] +) +if test "x$ac_cv_fips" = "xyes" ; then + CPPFLAGS="$CPPFLAGS -DOPENSSL_FIPS" + FIPS_MODE=yes + AC_SUBST(FIPS_MODE) +fi + +AC_ARG_WITH(fips, + [ --with-fips Enable OpenSSL FIPS mode], + [ + if test "x$withval" != "xno" ; then + INCLUDES="=l$ssldir/include" + AC_CACHE_CHECK([for FIPS mode], ac_cv_fips, [ + AC_TRY_COMPILE( + [ #include <openssl/fips.h> ], + [ FIPS_mode_set(1); ], + [ ac_cv_fips="yes" ], + [ ac_cv_fips="no" ] + ) + ]) + fi + ] +) +if test "x$ac_cv_fips" = "xyes" ; then + CPPFLAGS="$CPPFLAGS -DOPENSSL_FIPS" + FIPS_MODE=yes + AC_SUBST(FIPS_MODE) +fi +AM_CONDITIONAL(FIPS_MODE, test x$ac_cv_fips = xyes) + # Check for obsolete RSAref library AC_MSG_CHECKING([for obsolete RSAref library]) saved_LIBS="$LIBS" Only in stunnel-4.20: configure.ac.orig diff -u -r @stunnel-4.20/src/common.h stunnel-4.20/src/common.h --- @stunnel-4.20/src/common.h 2006-11-17 04:03:18.000000000 -0500 +++ stunnel-4.20/src/common.h 2007-03-26 18:35:03.000000000 -0400 @@ -321,6 +321,9 @@ #if SSLEAY_VERSION_NUMBER >= 0x00907000L #include <openssl/ocsp.h> #endif /* OpenSSL-0.9.7 */ +#ifdef OPENSSL_FIPS +#include <openssl/fips.h> +#endif #else /* HAVE_OPENSSL */ #include <lhash.h> #include <ssl.h> diff -u -r @stunnel-4.20/src/options.c stunnel-4.20/src/options.c --- @stunnel-4.20/src/options.c 2006-11-05 08:04:37.000000000 -0500 +++ stunnel-4.20/src/options.c 2007-03-26 18:35:03.000000000 -0400 @@ -556,7 +556,11 @@ /* ciphers */ switch(cmd) { case CMD_INIT: +#ifndef OPENSSL_FIPS section->cipher_list=SSL_DEFAULT_CIPHER_LIST; +#else + section->cipher_list="!ADH:!RC4:!RC2:!IDEA:!MD5:!NULL:TLSv1"; +#endif break; case CMD_EXEC: if(strcasecmp(opt, "ciphers")) @@ -564,7 +568,11 @@ section->cipher_list=stralloc(arg); return NULL; /* OK */ case CMD_DEFAULT: +#ifndef OPENSSL_FIPS log_raw("%-15s = %s", "ciphers", SSL_DEFAULT_CIPHER_LIST); +#else + log_raw("%-15s = %s", "ciphers", "!ADH:!RC4:!RC2:!IDEA:!MD5:!NULL:TLSv1"); +#endif break; case CMD_HELP: log_raw("%-15s = list of permitted SSL ciphers", "ciphers"); @@ -726,6 +734,31 @@ } #endif + /* fips mode */ +#ifndef USE_WIN32 + switch(cmd) { + case CMD_INIT: + options.option.fips_mode=0; + break; + case CMD_EXEC: + if(strcasecmp(opt, "fips")) + break; + if(!strcasecmp(arg, "yes")) + options.option.fips_mode = 1; + else if(!strcasecmp(arg, "no")) + options.option.fips_mode = 0; + else + return "argument should be either 'yes' or 'no'"; + return NULL; /* OK */ + case CMD_DEFAULT: + break; + case CMD_HELP: + log_raw("%-15s = yes|no FIPS mode", + "fips"); + break; + } +#endif + /* execargs */ #ifndef USE_WIN32 switch(cmd) { diff -u -r @stunnel-4.20/src/prototypes.h stunnel-4.20/src/prototypes.h --- @stunnel-4.20/src/prototypes.h 2006-11-11 08:03:05.000000000 -0500 +++ stunnel-4.20/src/prototypes.h 2007-03-26 18:35:03.000000000 -0400 @@ -142,6 +142,7 @@ unsigned int foreground:1; unsigned int syslog:1; /* log to syslog */ unsigned int rand_write:1; /* overwrite rand_file */ + unsigned int fips_mode:1; #ifdef USE_WIN32 unsigned int taskbar:1; /* enable the taskbar icon */ #endif diff -u -r @stunnel-4.20/src/stunnel.c stunnel-4.20/src/stunnel.c --- @stunnel-4.20/src/stunnel.c 2006-11-30 15:47:45.000000000 -0500 +++ stunnel-4.20/src/stunnel.c 2007-03-26 18:35:03.000000000 -0400 @@ -59,6 +59,7 @@ #ifndef USE_WIN32 int main(int argc, char* argv[]) { /* execution begins here 8-) */ +unsigned long e; main_initialize(argc>1 ? argv[1] : NULL, argc>2 ? argv[2] : NULL); signal(SIGPIPE, SIG_IGN); /* avoid 'broken pipe' signal */ @@ -72,6 +73,21 @@ signal(SIGHUP, signal_handler); /* signal(SIGSEGV, signal_handler); */ +#ifdef OPENSSL_FIPS + if(options.option.fips_mode) { + if (!FIPS_mode_set(1)) { + log_raw("Failed to enter FIPS mode"); + ERR_load_crypto_strings(); + while((e = ERR_get_error())) { + log_raw(ERR_error_string(e,NULL)); + } + return 1; /* failure */ + } else { + log_raw("FIPS mode enabled"); + } + } +#endif + main_execute(); return 0; /* success */

using an ocsp
by Samuel Landau 26 Mar '07

26 Mar '07

Hello, I am using stunnel 4.18 and openca-ocspd 1.5.1. The OCSPd uses a delegate certificate and the setup works when tested with openssl: $ openssl ocsp -issuer /home/landau/ssl/cacert.pem -serial 3 -url http://localhost:2560 -CAfile /home/landau/ssl/cacert.pem Response verify OK 3: good This Update: Mar 23 18:27:37 2007 GMT Next Update: Mar 26 10:56:33 2007 GMT But when it comes to using stunnel, I cannot figure out how to make it use properly the OCSP. I could see that stunnel 4.19 had more options for ocsp, but I am unsure this is related to my current issue. Besides, is there a way to have stunnel fall back on local cert/crl files if the ocsp server is not available ?

Solaris 10 and MySQL questions

My web servers database seems to be functioning as normal. I would like to verify that what I have is complete and effective. It is not apparent to me if I have finished construction or how to verify this works like I want it to. I'm not sure how I would verify that Stunnel is being used. Do I need to run Stunnel as a background service full time?

by lists＠d-ra.ath.cx 18 Mar '07

18 Mar '07

Hi, the following patch makes stunnel 4.20 to operate with TCP wrappers 7.6. I had not tried other versions of stunnel nor TCP wrappers. The problem is the missing libnsl, so TCP wrappers will never be activated in ./configure Regards Dieter --- configure.ac.orig 2007-03-17 12:57:32.000000000 +0100 +++ configure.ac 2007-03-17 12:55:19.000000000 +0100 @@ -310,7 +310,7 @@ AC_MSG_RESULT([no (autodetecting)]) AC_MSG_CHECKING([for hosts_access in -lwrap]) saved_LIBS="$LIBS" - LIBS="$saved_LIBS -lwrap" + LIBS="$saved_LIBS -lwrap -lnsl" AC_LINK_IFELSE( [AC_LANG_PROGRAM( [[int hosts_access(); int allow_severity, deny_severity;]],

Getting a "Peer suddenly disconnected" error
by David Goodwin 09 Mar '07

09 Mar '07

Hey all, I'm getting this in the /var/adm/messages log on the server side when attempting to connect from the client: Mar 8 22:23:33 SERVERNAME stunnel: [ID 821868 daemon.error] LOG3[27429:4]: SSL_connect: Peer suddenly disconnected I have the server configured as follows: cat /etc/stunnel/stunnel.test.conf client=yes debug=debug cert=/etc/stunnel/stunnel.pem [sunrpc] accept=112 connect=127.0.0.1:111 TIMEOUTclose=10 This is started just by running stunnel with the config file and then starting rpcbind normally. The client is configured as follows: # cat /etc/stunnel/stunnel.test.conf client=yes debug=debug cert=/etc/stunnel/imnxnsm0.pem [sunrpc] accept=111 connect=SERVERNAME:112 The error shows up when I attempt to run "rpcinfo -p 127.0.0.1".

This configuration is the closest I've been to success so far. Is there a better way for me to wrap rpcbind perhaps? Any help with this will be appreciated. Thanks, Civil

Download speed affected with stunnel help needed please.
by tom hammond 07 Mar '07

07 Mar '07

Using HFS 2.1d http://www.rejetto.com and Stunnel 4.20 on single WinXP machine. The list of parameters you are using for stunnel, and if you are running it standalone or from inetd/xinetd: socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 [https] accept = # connect = # TIMOUTclose = 0 I dont'understand 3-7 as given here: http://www.stunnel.org/support/ only used OpenSSL to make CERT Win32 OpenSSL v0.9.8e Light *************************************** Description: HFS is a webserver that can only utilize HTTP, therefore I turned to Stunnel to implement https. When using HTTPs: for UPLOADING I get full speed. When using HTTPs: for DOWNLoADING the speed in cut drastically, 20x slower. The odd thing is, multiple downloads can go at once eg: 20 connections @80kb/second However no single connection will get over 80 or 100kb/second I searched the net and couldn't find a solution, but continuously came across mention of "loopback" problems with stunnel and http servers (old posts) or saying stuff about Microsoft winsock, found a few mentions of VNC server having an option to "enable loopback connections" Another thing I saw but closed (oops) was mention of disabling an HTTP server in order to avoid loopback problems with HTTPS serving.(HFS has no option because it is designed to serve ONLY HTTP) I have tons of hope for an easy solution for the following reasons: #1, uploading works perfect #2 just downloaded demo of Easy File Sharing Web Server(not free like HFS) and the download speed works through HTTPS. I have no clue as to how to fix this, saw one entry in the stunnel config at ssl.org: socket = a:SO_BINDTODEVICE=lo I DID attempt to enter this line into the config under my 2 original entries, but then stunnel would not start.

High CPU system usage on Solaris
by armando.salvatori＠accenture.com 05 Mar '07

We use stunnel process to encrypt Oracle connections from a set of 4-6 application server. On the DB server, 20 cpus Solaris machine running Oracle, we have more then 400 LWPS for stunnel and the relative 400 oracle connections. We experience a huge amount of cpu usage (system component), about 40%, after stunnel setup (stunnel 4.15 version) Is it usual? Do you have experience on similar situation? Do you have any suggestions to improve cpu usage or to address performance issue/tuning?

RE: Stunnel Forks Out of Control
by Duncan Brown 24 Feb '07

24 Feb '07

Hi all, Ok, I've gone through my last log file for when this issue happens. There's "1130 finished (2 left)" (where 1030 is the port we're listening on) at 10:22am, for example. Then, the next "1130 finished" doesn't happen for about another 20 minutes (which is weird), and then says, "1131 finished (124 left)". It's at this point that a lot of "connection reset by peer"'s happen and "0 bytes sent to SSL" also happen. It looks as though there are a bunch of connections being accepted but not handled. Can anyone assist? The debug level 7 log file is available if necessary. Thanks again, guys. Cheers, Duncan

Hi all, As an update, it looks like I'm using Stunnel 4.15. I thought it said 4.20, unless I managed to compile an older version. Regardless, I think the problem is happening in both versions. It looks as though it can't catch up on processing cached requests or something. Does that help at all? Cheers, Duncan

Stunnel Forks Out of Control
by Duncan Brown 21 Feb '07

21 Feb '07

Hi all, I apologize if this issue appears in the archives but I've scoured them and can't find any similar instances (if this problem does occur in the archives then if someone could point it out to me I'd be grateful as well). So, here goes: I'm running Stunnel on Debian Linux. I run it in daemon mode and have the .conf file set to listen on a specific port and redirect to another port. Listening on the connecting end of Stunnel is another daemon I've created that listens on the same port for TCP traffic as part of a client-server application I have (a new process is forked for each connection). On the client end is a .NET application that communicates with the server via TCP with Stunnel installed. In my code, I've made sure that whenever a client-server session is finished, the server closes the socket, whether or not there was an error. Now, everything seems to work flawlessly for a period of time (this period of time is variable, from anywhere between 1 day to 1 month). Then, all of a sudden, Stunnel "explodes"; for example, while there might be one or two forks of my own daemon, there might be 128 instances of Stunnel, all of which are in a sleeping state (that is, if I run ps -aux, their "STAT" attribute is "S"), whereas before it exploded it was pretty much a 1:1 relationship. When it "explodes", I have to kill Stunnel and restart it, which is a pain in the rear-end given what I'm trying to do. Why is it doing this? How do I stop it from happening? I apologize again if this has already been brought up somewhere else, but I've been unable to find any references to any similar problems. If it's a "newbie" mistake or something I'll gladly accept it and learn from it. Please find below the information requested for a problem for the mailing list: - I'm using v4.20 - No parameters are used from the command-line when starting Stunnel; it just uses the standard .conf file which I've edited. - Output of "uname -a" : "Linux buffed 2.4.27-2-386 #1 Wed Aug 17 09:33:35 UTC 2005 i686 GNU/Linux" - I'm using libc v6 - Output of "gcc -v" : Reading specs from /usr/lib/gcc-lib/i486-linux/3.3.5/specs Configured with: ../src/configure -v --enable-languages=c,c++,java,f77,pascal,objc,ada,treelang --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-gxx-include-dir=/usr/include/c++/3.3 --enable-shared --enable-__cxa_atexit --with-system-zlib --enable-nls --without-included-gettext --enable-clocale=gnu --enable-debug --enable-java-gc=boehm --enable-java-awt=xlib --enable-objc-gc i486-linux Thread model: posix gcc version 3.3.5 (Debian 1:3.3.5-13) - I'm using OpenSSL v0.9.7e (25 Oct 2004) Thanks in advance for any help.

Stunnel on AIX 5.3 and AIX 5.2 - Solution
by Trevor Maistry 21 Feb '07

21 Feb '07

Hi, I downloaded stunnel version 4.05, changed the configuration file to use "cc" instead of "gcc" and compiled on AIX 5300-04 and AIX 5200-03. Compilations worked fine. However, you must compile on the machine you want to use it on. Otherwise you will have problems. Copy the "stunnel", "stunnel.pem" and sample "stunnel.conf-sample.in" files into /usr/local/bin. Rename the "stunnel.conf-sample.in" to " "stunnel.conf". Change the "stunnel.conf" accordingly and start "stunnel" like so "./stunnel stunnel.conf". Hope this helps.

greetings. clients connects normally when not using ssl (stunnel). when using ssl the connection on the client end appears to take about a minute but does eventually work (mail is sent through encrypted). shown below is the log with debug=7 and a space between the area where a "pause" seems to be, ideas on what could be occurring during this time to induce the "pause"? client = machine making connection. server = machine running stunnel accepting the connection. 2007.02.14 12:24:06 LOG7[69377:134631424]: imaps accepted FD=9 from client:62847 2007.02.14 12:24:06

"The most recent stable Stunnel version?"
by Roger Fulton 04 Feb '07

04 Feb '07

Hi, I've checked the support pages. I've browsed the mailing list archives. I've perused the ChangeLog file. I can't find an answer to this question: At http://www.stunnel.org/download/binaries.html is stated "The most recent stable Stunnel version is flagged with a red asterisk (*)." I've used two different browsers, and I'll be danged if I see *any* version marked with *any* asterisk, red or otherwise. Would someone kindly direct this Stunnel newbie to the "most recent stable Stunnel version?" TIA.

Oracle JDBC Failover not working
by Dario Mariani 02 Feb '07

02 Feb '07

Hi all. We have a problem here with this configuration. before stunnel: BEA Weblogic, 2 JDBC, server1:1521 and server2:1521 Two SunCluster nodes with Oracle OPS/RAC (active-active conf), with NO shared address. So "server1" and "server2" are the phisical address. after stunnel: the JDBC config is 127.0.0.1:10001 and 127.0.0.1:10002 stunnel client is 10001->server1:11521 and 10002->server2:11521 stunnel server is 11521->localhost:1521 When we shut down the server1 (so oracle, listener and stunnel server is not responding), BEA cannot failover. A quick analisys shows that: 1. the JDBC connects to stunnel client, that accept the connection 2. stunnel client fails to connect to stunnel server 3. stunnel client close the connection with the JDBC 4. the JDBC cannot deal with the situation and doesn't failover. It seems like JDBC doesn't failover when he can open a connection but oracle doesn't reply. What i need is: is possible for Stunnel client to FIRST try to connect to the server, and then eventually accept the connection from the jdbc? Bye, dario.

Intermediate Cert validation problem
by Eric McCombs 31 Jan '07

31 Jan '07

I'm experiencing a problem validating intermediate cert on our Stunnel configuration. We are using Stunnel to forward IMAP, POP and SMTP SSL ports from our vpn server to our internal mail server. We originally used a self-signed cert on the vpn server. When clients connect via Outlook, Outlook Express, Thunderbird and various cell phone mail programs they received a warning message (Unable to verify identity of xxx) about the self-signed cert. To resolve this issue we purchased a SSL cert from Verisign to install on the vpn server. We generated the key and CSR and received the new cert from Verisign, which also requires an intermediate cert for verification. We have tried various methods to have the certs validated, combining the key, intermediate cert and server cert in one file, pointing to the CA_file, etc. but continue to see the Unable to verify identity message. Has anybody else encountered this problem and found a way to resolve the problem? Thanks in advance. Eric McCombs

To all, Can Stunnel communicate bi-directionally over a single port? Or does it listen on one and communicate on a different one? Thanks Dean

Re: [stunnel-users] How is stunnel started ? / Searching stunnel service name
by Ben Stover 22 Jan '07

22 Jan '07

Hmm that is very curious. I investigated now all runnig services and did not found the stunnel service. The only reason I can find for this is that the service name does not contain "stunnel" in its name. How is it called otherwise? My services here (under Win2000) are (when I type "net start" at the command prompt): Alerter AVK Monitor AVK Service AVKProxy COM+ Event System Computer Browser DHCP Client Distributed Link Tracking Client Event Log IPSEC Policy Agent Logical Disk Manager MGABGEXE Network Connections PDFCreatorMessages PDScheduler Plug and Play Print Spooler Protected Storage Remote Access Connection Manager Remote Procedure Call (RPC) Remote Registry Service Removable Storage RunAs Service Security Accounts Manager Server Still Image Service System Event Notification Task Scheduler TCP/IP NetBIOS Helper Service Telephony Washer AutoComplete Windows Management Instrumentation Windows Management Instrumentation Driver Extensions Workstation Is it IPSEC Policy agent the service for stunnel ?

This feature is already implemented since version 4.06, 2004.12.26. Here is the relevant frament of ChangeLog: "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." Best regards, Mike

Error I am receiving in stunnel logfile (help please!)
by Eric S. Eberhard 20 Jan '07

20 Jan '07

Hello Everyone, I tried it on 4.3.3 as well with my re-compiled version ... below are all 5 lines in the log file. stunnel 4.16 on powerpc-ibm-aix4.3.3.0 with OpenSSL 0.9.8c 05 Sep 2006 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv4 stunnel connected from 127.0.0.1:37690 remote socket: Addr family not supported by protocol (66) Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket I also recompiled the latest stunnel with and without IPv6 ... same result with IPv6 as with IPv4 and same result with the new version: stunnel 4.20 on powerpc-ibm-aix4.3.3.0 with OpenSSL 0.9.8c 05 Sep 2006 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 stunnel accepted connection from ::ffff:127.0.0.1:59274 remote socket: Addr family not supported by protocol (66) Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket I have been using this for a while but I had to transfer to a new machine (AIX 4.3 to 5.3) and had to recompile my software and get a newer stunnel. I am now on 4.20 I thought it might be related to ipv4 versus ipv6 ... according to AIX documentation I had it set up for ipv4. I tried ipv6 for ducks, no difference. My inetd.conf line is: visanet stream tcp nowait root /visanet/ssl/stunnel stunnel visanet stream tcp6 nowait root /visanet/ssl/stunnel stunnel The second is IPv6. The error is somehow on the remote though. I can connect to the remote with telnet ... just not stunnel. It seems that depending on how inetd is configured, stunnel accepts either the IPv4 or IPv6 whether or not I compil it using USE_IPv6 1 or not ... what am I missing!? I really only need to hack it to connect to this one site, at least for the moment. /visanet/ssl/visanet.conf My .conf file is: output = /tmp/stunnel.log debug = 5 RNDfile = /visanet/ssl/stunnel.rnd RNDoverwrite = yes client = yes connect = ssllab.pgs.wcom.net:443 sslVersion = SSLv2 cert = /visanet/ssl/stunnel.pem EGD = /etc/egd-pool My guess is that this is something really stupid I am doing, but it is not obvious. Any help would be appreciated. I would even take an AIX executable for stunnel that works! Or whatever the correct configure options are. Or???? Thanks, Eric This email sent by: Eric S.

Re: [stunnel-users] How is stunnel started ?

Probably through a Run entry in the registry. You should definitely try to use something like CodeStuff's Starter: http://members.lycos.co.uk/codestuff/ Best regards.
