ssl mutual authentication
by Simon Santoro 09 Mar '08

09 Mar '08

Hello all. I am sure I am missing something really obvious here, but I can't get this to work. HTTP client (localhost) -> stunnel (localhost) -> HTTPS server (remote host) I'd like to user stunnel as proxy for my HTTP requests that go to a HTTPS server (apache if that makes any difference) on a remote host (fresh) that uses a cert to authenticate the request. I wrote this little ruby script[2] to test the request, and it works, so i am sure that on the server/client/cert end there is no problem. Now I'd like to use a simple wget or w3m to get the file from the remote server trough stunnel, but I keep getting SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed The only difference between the ruby script and the stunnel setup is that in the ruby script i have two different files for the crt and the key, and with stunnel I joined those files together with cat s2(a)magnesium.key s2(a)magnesium.crt >s2(a)magnesium.pam on localhost i run: $ stunnel -r fresh:443 -d localhost:11443 -c -f -D 7 -c -S 0 -p certs/s2(a)magnesium.pem -a certs/ -A certs/freshCA.crt -v 3 -P none 2008.03.09 21:21:38 LOG5[9026:3082811056]: Using 'fresh.443' as tcpwrapper service name 2008.03.09 21:21:38 LOG7[9026:3082811056]: RAND_status claims sufficient entropy for the PRNG 2008.03.09 21:21:38 LOG6[9026:3082811056]: PRNG seeded successfully 2008.03.09 21:21:38 LOG7[9026:3082811056]: Certificate: certs/s2(a)magnesium.pem Enter PEM pass phrase: 2008.03.09 21:21:40 LOG7[9026:3082811056]: cert_defaults is 0 2008.03.09 21:21:40 LOG7[9026:3082811056]: cert_dir is certs/ 2008.03.09 21:21:40 LOG7[9026:3082811056]: cert_file is certs/freshCA.crt 2008.03.09 21:21:40 LOG7[9026:3082811056]: Loaded verify certificates from certs/freshCA.crt 2008.03.09 21:21:40 LOG7[9026:3082811056]: Set verify directory to certs/ 2008.03.09 21:21:40 LOG5[9026:3082811056]: Peer certificate location certs/ 2008.03.09 21:21:40 LOG5[9026:3082811056]: stunnel 3.26 on i486-pc-linux-gnu PTHREAD+LIBWRAP with OpenSSL 0.9.8e 23 Feb 2007 2008.03.09 21:21:40 LOG7[9026:3082811056]: No pid file being created 2008.03.09 21:21:40 LOG5[9026:3082811056]: FD_SETSIZE=1024, file ulimit=1024 -> 500 clients allowed 2008.03.09 21:21:40 LOG7[9026:3082811056]: SO_REUSEADDR option set on accept socket 2008.03.09 21:21:40 LOG7[9026:3082811056]: fresh.443 bound to 127.0.0.1:11443 then, I try to connect to localhost:11443 with w3m, in the hope that my HTTP request is encrypted and send to fresh:443, and stunnel should check if the PEER certificate is correct, but all I get is: 2008.03.09 21:26:44 LOG7[9214:3082585776]: fresh.443 accepted FD=6 from 127.0.0.1:43888 2008.03.09 21:26:44 LOG7[9214:3082423184]: fresh.443 started 2008.03.09 21:26:44 LOG5[9214:3082423184]: fresh.443 connected from 127.0.0.1:43888 2008.03.09 21:26:44 LOG7[9214:3082423184]: fresh.443 connecting 192.168.0.2:443 2008.03.09 21:26:44 LOG7[9214:3082423184]: Remote FD=7 initialized 2008.03.09 21:26:44 LOG7[9214:3082423184]: Relying on OpenSSL RSA Blinding. 2008.03.09 21:26:44 LOG7[9214:3082423184]: SSL state (connect): before/connect initialization 2008.03.09 21:26:44 LOG7[9214:3082423184]: SSL state (connect): SSLv3 write client hello A 2008.03.09 21:26:45 LOG7[9214:3082423184]: SSL state (connect): SSLv3 read server hello A 2008.03.09 21:26:45 LOG5[9214:3082423184]: VERIFY OK: depth=1, /C=IT/O=S2 corp./CN=S2/emailAddress=s2@fresh 2008.03.09 21:26:45 LOG4[9214:3082423184]: VERIFY ERROR ONLY MY: no cert for /C=IT/O=S2 corp./CN=fresh 2008.03.09 21:26:45 LOG7[9214:3082423184]: SSL alert (write): fatal: certificate unknown 2008.03.09 21:26:45 LOG3[9214:3082423184]: SSL_connect: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed 2008.03.09 21:26:45 LOG7[9214:3082423184]: fresh.443 finished (0 left) Did I something wrong?

I setup stunnel this afternoon to work with Newshosting. It was working fine but now I cannot connect using my desktop running Vista. I receive this message: SSL_connect: 14094406: error:14094406:SSL routines:SSL3_READ_BYTES:sslv3 alert decompression failure Stunnel connects fine on my laptop which is also running Vista. Help, Earl Stenlund

Username authentication
by Joe Kemp 07 Mar '08

07 Mar '08

I want to try to use stunnel as a "simple" client vpn. It solves all of my encryption issues but I would like to verify a username/password before it lets the traffic through. I didn't see any patches or hacks out there that did this. Has this been attempted before or am I on my own. I would also be interested in other solutions based on openssl that are not network device level VPNs clients. Already using client side certificates and I know that is the normal SSL authentication mechanism.... Thanks. -Joe

Send delay?
by Colin E 04 Mar '08

04 Mar '08

Please can you help a hardware engineer, who almost understands what he's doing. I'm using sTunnel 4.21 on a Windows 2000 machine, to provide a TCP program with SSL. This works very well. However the application is very time critical and must finish sending block of XML as quickly as possible. I suspect there is a delay in either sTunnel or openSSL, while it waits to see if there are any more characters before sending a packet. Is this correct? If it is, is there a work round. -- View this message in context: http://www.nabble.com/Send-delay--tp15826043p15826043.html Sent from the Stunnel - Users mailing list archive at Nabble.com.

Hello to all! I'm trying to set up Stunnel for the first time. I hope to use it with HFS. I followed directions found on HFS website and ran into a problem creating a pem file. Could someone direct me to information about installing Stunnel? Or help me directly by sharing with me how to install Stunnel? I sincerely appreciate your help!!! Rod

Hallo, I have found 2 Bugs. 1. In Version 4.21: No Taskbar Icon is displayed when the service starts. Although the taskbar ist set in config file (taskbar = yes). 2. In probably all Versions (I have testet 4.18, 4.20 and 4.21) If i started the service over Start -> Programm Files -> stunnel -> Service Start (stunnel -start) no log files are written. If i start the service over services.msc from Windows or "sc start stunnel" log files are written. The icon log displayed the following message in version 4.18 and 4.20 2007.11.09 09:41:03 LOG3[2396:2400]: stunnel.log: Broken pipe (32) 2007.11.09 09:41:03 LOG3[2396:2400]: Unable to open output file: stunnel.log Best Regards Jan

VNC, STUNNEL & HTTPTUNNEL ----- (((VNC)SSL)HTTP)
by sean bhola 25 Feb '08

25 Feb '08

I need to connect to my PC at work from home. The firewall at work has only ports 80 (http) and 443 (https) open, I also think there is a proxy. I was wondering which scenario would work. 1: To encapsulate vnc traffic within ssl using stunnel and pass it though port 443, OR 2: To encapsulate vnc traffic within ssl using stunnel, then encapsulate that within http using httptunnel and pass through port 80 OR 3: To encapsulate vnc traffic within http, then encapsulate that within ssl using stunnel and pass through port 443 I read this article http://www.securityfocus.com/infocus/1677 but still had the concerns above. Help would be much appreciated. Thanks. Sean
