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. Thanks, -John Stunnel.conf on server: cert = my.pem verify = 3 CAfile = my.pem socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 taskbar=no debug = 5 output = stunnel.log [rsynctnl] accept=12345 connect=873 ciphers = AES128-SHA Stunnel.conf on client: cert = my.pem taskbar = no socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 debug = 5 output = stunnel.log client = yes [rsynctnl] accept=12345 connect=10.9.8.7:12345 -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

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? Do I need to run Stunnel as a background service full time? Is there something I am missing here?

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.

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
by mdpeters 25 Mar '07

25 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. Do I need to run Stunnel as a background service full time? Is there something I am missing here? ++++++ # /usr/local/sbin/stunnel -version stunnel 4.20 on sparc-sun-solaris2.10 with OpenSSL 0.9.8e 23 Feb 2007 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv4 Global options debug = 5 pid = /usr/local/var/run/stunnel/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /usr/local/etc/stunnel/stunnel.pem ciphers = ALL:!ADH:+RC4:@STRENGTH key = /usr/local/etc/stunnel/stunnel.pem session = 300 seconds sslVersion = SSLv3 for client, all for server TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none # gcc -v Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.10/3.3.2/specs Configured with: ../configure --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin/ld --disable-nls Thread model: posix gcc version 3.3.2 # uname -a SunOS slinky 5.10 Generic_118833-17 sun4u sparc SUNW,Ultra-80 # /usr/local/sbin/stunnel -sockets Socket option defaults: Option Accept Local Remote OS default SO_DEBUG -- -- -- 0 SO_DONTROUTE -- -- -- 0 SO_KEEPALIVE -- -- -- 0 SO_LINGER -- -- -- 0:0 SO_OOBINLINE -- -- -- 0 SO_RCVBUF -- -- -- 65535 SO_SNDBUF -- -- -- 65535 SO_RCVLOWAT -- -- -- -- SO_SNDLOWAT -- -- -- -- SO_RCVTIMEO -- -- -- -- SO_SNDTIMEO -- -- -- -- SO_REUSEADDR 1 -- -- 0 IP_TOS -- -- -- 0 IP_TTL -- -- -- 64 TCP_NODELAY -- -- -- 0 # openssl ciphers -v DHE-RSA-AES256-SHA SSLv3 Kx=DH Au=RSA Enc=AES(256) Mac=SHA1 DHE-DSS-AES256-SHA SSLv3 Kx=DH Au=DSS Enc=AES(256) Mac=SHA1 AES256-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA1 EDH-RSA-DES-CBC3-SHA SSLv3 Kx=DH Au=RSA Enc=3DES(168) Mac=SHA1 EDH-DSS-DES-CBC3-SHA SSLv3 Kx=DH Au=DSS Enc=3DES(168) Mac=SHA1 DES-CBC3-SHA SSLv3 Kx=RSA Au=RSA Enc=3DES(168) Mac=SHA1 DES-CBC3-MD5 SSLv2 Kx=RSA Au=RSA Enc=3DES(168) Mac=MD5 DHE-RSA-AES128-SHA SSLv3 Kx=DH Au=RSA Enc=AES(128) Mac=SHA1 DHE-DSS-AES128-SHA SSLv3 Kx=DH Au=DSS Enc=AES(128) Mac=SHA1 AES128-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(128) Mac=SHA1 IDEA-CBC-SHA SSLv3 Kx=RSA Au=RSA Enc=IDEA(128) Mac=SHA1 IDEA-CBC-MD5 SSLv2 Kx=RSA Au=RSA Enc=IDEA(128) Mac=MD5 RC2-CBC-MD5 SSLv2 Kx=RSA Au=RSA Enc=RC2(128) Mac=MD5 RC4-SHA SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=SHA1 RC4-MD5 SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=MD5 RC4-MD5 SSLv2 Kx=RSA Au=RSA Enc=RC4(128) Mac=MD5 EDH-RSA-DES-CBC-SHA SSLv3 Kx=DH Au=RSA Enc=DES(56) Mac=SHA1 EDH-DSS-DES-CBC-SHA SSLv3 Kx=DH Au=DSS Enc=DES(56) Mac=SHA1 DES-CBC-SHA SSLv3 Kx=RSA Au=RSA Enc=DES(56) Mac=SHA1 DES-CBC-MD5 SSLv2 Kx=RSA Au=RSA Enc=DES(56) Mac=MD5 EXP-EDH-RSA-DES-CBC-SHA SSLv3 Kx=DH(512) Au=RSA Enc=DES(40) Mac=SHA1 export EXP-EDH-DSS-DES-CBC-SHA SSLv3 Kx=DH(512) Au=DSS Enc=DES(40) Mac=SHA1 export EXP-DES-CBC-SHA SSLv3 Kx=RSA(512) Au=RSA Enc=DES(40) Mac=SHA1 export EXP-RC2-CBC-MD5 SSLv3 Kx=RSA(512) Au=RSA Enc=RC2(40) Mac=MD5 export EXP-RC2-CBC-MD5 SSLv2 Kx=RSA(512) Au=RSA Enc=RC2(40) Mac=MD5 export EXP-RC4-MD5 SSLv3 Kx=RSA(512) Au=RSA Enc=RC4(40) Mac=MD5 export EXP-RC4-MD5 SSLv2 Kx=RSA(512) Au=RSA Enc=RC4(40) Mac=MD5 export ++++++

Getting a "Peer suddenly disconnected" error

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

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.

init_ssl: s_poll_wait timeout

I am using a Eudora client configured to use STARTLS to send mail through stunnel to a sendmail server. The stunnel config is as follows: cert = /usr/local/etc/stunnel/stunnel.pem key = /usr/local/etc/stunnel/stunnel.pem socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 options = DONT_INSERT_EMPTY_FRAGMENTS delay = yes TIMEOUTconnect = 300 TIMEOUTbusy = 300 setuid = smtpauth setgid = smtpauth debug = 7 client = no foreground = yes pid = [smtps] accept = 465 connect = localhost:25 protocol=smtp When I send mail the connection is established with port 465 on stunnel but it fails to negotiate the ssl session. THis is the log: 2007.03.06 15:45:08 LOG7[17753:1024]: Snagged 64 random bytes from /root/.rnd 2007.03.06 15:45:08 LOG7[17753:1024]: Wrote 1024 new random bytes to /root/.rnd 2007.03.06 15:45:08 LOG7[17753:1024]: RAND_status claims sufficient entropy for the PRNG 2007.03.06 15:45:08 LOG7[17753:1024]: PRNG seeded successfully 2007.03.06 15:45:08 LOG7[17753:1024]: Configuration SSL options: 0x00000800 2007.03.06 15:45:08 LOG7[17753:1024]: SSL options set: 0x00000800 2007.03.06 15:45:08 LOG7[17753:1024]: Certificate: /usr/local/etc/stunnel/stunnel.pem 2007.03.06 15:45:08 LOG7[17753:1024]: Certificate loaded 2007.03.06 15:45:08 LOG7[17753:1024]: Key file: /usr/local/etc/stunnel/stunnel.pem 2007.03.06 15:45:08 LOG7[17753:1024]: Private key loaded 2007.03.06 15:45:08 LOG7[17753:1024]: SSL context initialized for service smtps 2007.03.06 15:45:08 LOG5[17753:1024]: stunnel 4.20 on i686-pc-linux-gnu with OpenSSL 0.9.7l 28 Sep 2006 2007.03.06 15:45:08 LOG5[17753:1024]: Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv4 2007.03.06 15:45:08 LOG6[17753:1024]: file ulimit = 1024 (can be changed with 'ulimit -n') 2007.03.06 15:45:08 LOG6[17753:1024]: poll() used - no FD_SETSIZE limit for file descriptors 2007.03.06 15:45:08 LOG5[17753:1024]: 500 clients allowed 2007.03.06 15:45:08 LOG7[17753:1024]: FD 3 in non-blocking mode 2007.03.06 15:45:08 LOG7[17753:1024]: FD 4 in non-blocking mode 2007.03.06 15:45:08 LOG7[17753:1024]: FD 5 in non-blocking mode 2007.03.06 15:45:08 LOG7[17753:1024]: SO_REUSEADDR option set on accept socket 2007.03.06 15:45:08 LOG7[17753:1024]: smtps bound to 0.0.0.0:465 2007.03.06 15:45:08 LOG7[17753:1024]: No pid file being created 2007.03.06 15:45:18 LOG7[17753:1024]: smtps accepted FD=6 from 208.41.111.165:2542 2007.03.06 15:45:18 LOG7[17755:1026]: smtps started 2007.03.06 15:45:18 LOG7[17755:1026]: FD 6 in non-blocking mode 2007.03.06 15:45:18 LOG7[17755:1026]: TCP_NODELAY option set on local socket 2007.03.06 15:45:18 LOG5[17755:1026]: smtps accepted connection from 208.41.111.165:2542 2007.03.06 15:45:18 LOG7[17755:1026]: SSL state (accept): before/accept initialization 2007.03.06 15:45:20 LOG6[17755:1026]: init_ssl: s_poll_wait timeout 2007.03.06 15:45:20 LOG5[17755:1026]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2007.03.06 15:45:20 LOG7[17755:1026]: smtps finished (0 left) 2007.03.06 15:47:00 LOG3[17753:1024]: Received signal 2; terminating Can anyone tell me what I am doing wrong?

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?
