Stunnel never really connects
by Pat Riehecky 20 Dec '07

20 Dec '07

I am trying to send email over stunnel from a client that doesn't support encryption to a server that does. The local socket opens just fine, but it never really seems to connect to the remote server. A tcpdump shows only three packets exchanged between the two systems (Syn, Syn/Ack, Ack). The behavior is the same regardless of which tls enabled port I point stunnel at. I am able to connect to these ports via telnet and send email so I know the connection can be negotiated. I am using the 4.21 build for windows (XP SP2) found on the main webpage. Help! --- stunnel.conf --- ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Workaround for Eudora bug ; my email client isn't eudora, but given how ; it doesn't support standards like encrypted ; transport..... options = DONT_INSERT_EMPTY_FRAGMENTS ; Some debugging stuff useful for troubleshooting debug = 7 ; Use it for client mode client = yes [smtp] accept = 127.0.0.1:25 connect = mailserver.mydomain.tld:587 ;connect = mailserver.mydomain.tld:465 ;connect = mailserver.mydomain.tld:25 protocol = smtp

'PIN' engine control command
by Ludolf Holzheid 14 Dec '07

14 Dec '07

Dear list, I'm trying to use stunnel on Windows with an USB token (`CryptoMate' from ACS). However, I can't manage to make stunnel ask for the token PIN: o Loading the private key works if I specify the PIN in the configuration file (`engineCtrl = PIN:...'). o If there is no `PIN' engine control option in the configuration file, loading the private key fails. The log message are: error stack: 26096080 : error:26096080:engine routines:ENGINE_load_private_key:failed loading private key error stack: 800050A0 : error:800050A0:Vendor defined:PKCS11_login:PIN incorrect Do I have to add a special engine control option to the configuration file in order to get asked for the PIN or is it intended to `just work'?

rtmps with stunnel on linux
by David Schulberg 14 Dec '07

14 Dec '07

Hi, Cannot get rtmps working with Firefox (IceWeasel) on Linux. I have rtmps working fine with Firefox and IE on Windows XP. The error I see in stunnel (see below) when I try rtmps through a Linux browser is "peer suddenly disconnected". Also curious that there are 2 attempts made. 2007.12.13 16:31:41 LOG7[2624:1192]: https accepted FD=212 from 124.190.241.7:59728 2007.12.13 16:31:41 LOG7[2624:1192]: Creating a new thread 2007.12.13 16:31:41 LOG7[2624:1192]: New thread created 2007.12.13 16:31:41 LOG7[2624:2576]: https started 2007.12.13 16:31:41 LOG7[2624:2576]: FD 212 in non-blocking mode 2007.12.13 16:31:41 LOG7[2624:2576]: TCP_NODELAY option set on local socket 2007.12.13 16:31:41 LOG5[2624:2576]: https accepted connection from 124.190.241.7:59728 2007.12.13 16:31:41 LOG7[2624:2576]: SSL state (accept): before/accept initialization 2007.12.13 16:31:41 LOG3[2624:2576]: SSL_accept: Peer suddenly disconnected 2007.12.13 16:31:41 LOG5[2624:2576]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2007.12.13 16:31:41 LOG7[2624:2576]: https finished (0 left) 2007.12.13 16:31:41 LOG7[2624:1192]: https accepted FD=236 from 124.190.241.7:59729 2007.12.13 16:31:41 LOG7[2624:1192]: Creating a new thread 2007.12.13 16:31:41 LOG7[2624:1192]: New thread created 2007.12.13 16:31:41 LOG7[2624:2572]: https started 2007.12.13 16:31:41 LOG7[2624:2572]: FD 236 in non-blocking mode 2007.12.13 16:31:41 LOG7[2624:2572]: TCP_NODELAY option set on local socket 2007.12.13 16:31:41 LOG5[2624:2572]: https accepted connection from 124.190.241.7:59729 2007.12.13 16:31:41 LOG7[2624:2572]: SSL state (accept): before/accept initialization 2007.12.13 16:31:41 LOG3[2624:2572]: SSL_accept: Peer suddenly disconnected 2007.12.13 16:31:41 LOG5[2624:2572]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2007.12.13 16:31:41 LOG7[2624:2572]: https finished (0 left) Regards, David Schulberg

newbie config not running
by fuzzy_4711 12 Dec '07

12 Dec '07

Hello list. I am new to stunnel and do have some problems to get it running. The server is a WinXPSP2 behind a router. The router has port forwarding enabled for port 9999 to the stunnel server (4.21). On the same box a vnc server is running on port 5900 which I like to tunnel. Firewall is opened. The netstat -a -n shows the server listening on the desired port (9999). My server config looks like that: cert = stunnel.pem ;key = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS ; Authentication stuff ;verify = 2 ; Don't forget to c_rehash CApath ;CApath = certs ; It's often easier to use CAfile ;CAfile = certs.pem ; Don't forget to c_rehash CRLpath ;CRLpath = crls ; Alternatively you can use CRLfile ;CRLfile = crls.pem ; Some debugging stuff useful for troubleshooting ;debug = 7 ;output = stunnel.log ; Use it for client mode ;client = yes [pop3s] accept = 995 connect = 110 [imaps] accept = 993 connect = 143 [ssmtp] accept = 465 connect = 25 [VNC Server] accept = 9999 connect = 5900 The client side is a linux box with config setting: client = yes [VNC Server] accept = 5900 connect = 9999 I turned on debugging and stunnel.log seems to be okay - no error messages. But I am not able to get an connection. What am I doing wrong? Stefan

server reads ecrypted data on connect ?
by Nikolaj G. 10 Dec '07

10 Dec '07

Hello stunnel'ers, First of all - im a newbie into openssl and stunnel. Im trying to stunnel between my own java socket server and client. The stunnel is established, but the server reads encrypted data on connect. Since I dont send anything, Im surprised to see encrypted data in the server log. Could someone please help. Ive managed to create a root certificate, a request and signing it, using: http://www.eclectica.ca/howto/ssl-cert-howto.php Thanks in advance. /nikolaj PS see configuration below: ----------------------------------------------- Packages (Fedora Core 6): openssl-devel-0.9.8b-15.fc6 openssl-0.9.8b-15.fc6 stunnel-4.15-2 ----------------------------------------------- The SERVER stunnel.conf: ; Certificate/key is needed in server mode CAfile = /root/ssl/cacert.pem cert = /root/ssl/key-cert.pem pid = /root/ssl/stunnel.pid ; Some debugging stuff useful for troubleshooting debug = 7 foreground=yes #setuid = stunnel #setgid = stunnel [mystunnel] accept = ratata.cirque.dk:998 connect = 127.0.0.1:8200 ----------------------------------------------- The CLIENT stunnel.conf: ; Certificate/key is needed in server mode CAfile = /root/ssl/eclectica/cacert.pem pid = /root/ssl/eclectica/stunnel.pid ; Some debugging stuff useful for troubleshooting debug = 7 foreground=yes ; enable client mode client = yes [mystunnel] accept = 127.0.0.1:998 connect = ratata.cirque.dk:8200 ____________________________________________________________________________________ Never miss a thing.

HTTPS hardcoded redirects
by Ezio Ostorero 10 Dec '07

10 Dec '07

All, I have a problem similar to the one described in http://mirt.net/pipermail/stunnel-users/2006-October/001324.html i.e. I ***wish*** to use the recording functionalities of JMeter while accessing an apache-SSL-secured Tomcat web server. JMeter does not allow recording on SSL so I have to ... un-cipher my HTTPS sessions, stunnel looks like the right choice. Being an stunnel newbie, I started here: http://www.stunnel.org/examples/https_client.html , this HOWTO looks quite close to my configuration. We have a plain-vanilla tomcat server behind an apache/SSL, and I want to access this web application from an HTTP-only browser. So, I configure stunnel as a "client", I run it on my PC, with the following configuration: [psuedo-https] accept = 8080 connect = <server>:443 TIMEOUTclose = 0 I read it as follows: stunnel talk cleartext HTTP on the local 8080 port and forwards in crypted HTTPS on the <server> port 443 I set the URL in my browser to http://localhost:8080/oi/ and this happens: 1) Ethereal sez that my PC and <server> start an SSLv3 conversation, good, we're on track 2) I have an HTTP analyzer plugged in my browser that shows me the content of the first GET that is a redirect to an SSO server (on the same <server>:443 port) for user authentication https://<server>/ssoserver/login?service=...... 3) My browser then issue a GET to https://<server>/ssoserver/login?service=...... and is GAME OVER, my beloved stunnel is cleanly bypassed by the hardcoded https://<server>/ string Any suggestion? Is it a dead end? Any dirty trick I could play with? Such as running multiple stunnel instances, setting <server> = localhost in my hosts file etc.?

Yup, just like the documentation (INSTALL.W32) says: 1) install mingw32 cross-compiler o a Unix/Linux machine (native compilation on a Windows machine is possible, but not supported) [...] 5) type "make stunnel.exe" > You seem to be mixing up (the names of) unix libs with windows ones.
