Usint Stunnel in combination with tinyproxy and PSK
by Christoph Malin 26 Feb '16

26 Feb '16

Hello, I have tinyproxy running on my server. Now I would like to add stunnel with a pres shared key (username, password combination). Is it possible to use this combination as a Proxy on my normal web browser e.g. firefox? So that stunnel ist only used on server side? greetings Christoph

User-agent string
by Josh Rabinowitz 22 Feb '16

22 Feb '16

Is there a way to force stunnel to use a specific user-agent string? I have mulled through documentation, this list, and other places with no results. The reason I ask, is the proxy I am going through is super strict, well not really. It will accept 'lynx' as a user-agent (among others), but it needs something. I cannot figure out how to tell stunnel to use something like this. 5.30 on both ends, here is debug 7 from the client (IPs changed for privacy) after a config reload and ssh attempt: 2016.02.22 09:22:08 LOG5[main]: Reading configuration from file stunnel.conf 2016.02.22 09:22:08 LOG5[main]: UTF-8 byte order mark not detected 2016.02.22 09:22:08 LOG5[main]: FIPS mode disabled 2016.02.22 09:22:08 LOG5[main]: Configuration successful 2016.02.22 09:22:15 LOG7[4]: Service [ssh] started 2016.02.22 09:22:15 LOG5[4]: Service [ssh] accepted connection from 127.0.0.1:56690 2016.02.22 09:22:15 LOG6[4]: failover: round-robin, starting at entry #1 2016.02.22 09:22:15 LOG6[4]: s_connect: connecting [webproxyIP]:8080 2016.02.22 09:22:15 LOG7[4]: s_connect: s_poll_wait [webproxyIP]:8080: waiting 10 seconds 2016.02.22 09:22:15 LOG5[4]: s_connect: connected [webproxyIP]:8080 2016.02.22 09:22:15 LOG5[4]: Service [ssh] connected remote server from [clientIP]:56691 2016.02.22 09:22:15 LOG7[4]: Remote descriptor (FD=844) initialized 2016.02.22 09:22:15 LOG7[4]: -> CONNECT [remoteIP]:443 HTTP/1.1 2016.02.22 09:22:15 LOG7[4]: -> Host: [remoteIP]:443 2016.02.22 09:22:15 LOG7[4]: -> 2016.02.22 09:22:15 LOG7[4]: <- HTTP/1.1 403 Forbidden 2016.02.22 09:22:15 LOG3[4]: CONNECT request rejected 2016.02.22 09:22:15 LOG7[4]: <- Cache-Control: no-cache 2016.02.22 09:22:15 LOG7[4]: <- Pragma: no-cache 2016.02.22 09:22:15 LOG7[4]: <- Content-Type: text/html; charset=utf-8 2016.02.22 09:22:15 LOG7[4]: <- Proxy-Connection: close 2016.02.22 09:22:15 LOG7[4]: <- Connection: close 2016.02.22 09:22:15 LOG7[4]: <- Content-Length: 3164 2016.02.22 09:22:15 LOG7[4]: <- 2016.02.22 09:22:15 LOG5[4]: Connection reset: 0 byte(s) sent to SSL, 0 byte(s) sent to socket 2016.02.22 09:22:15 LOG7[4]: Remote descriptor (FD=844) closed 2016.02.22 09:22:15 LOG7[4]: Local descriptor (FD=1116) closed 2016.02.22 09:22:15 LOG7[4]: Service [ssh] finished (0 left) client config: cert = stunnel.pem client = yes [ssh] accept = 127.0.0.1:2222 protocol= connect connect = [webproxyIP]:8080 protocolHost = [remoteIP]:443 PSKsecrets = psk1.txt debug = 7 Confirmed working from other hosts outside of this network.

Using CAPI Engine for client authentication
by Shay Cohen 18 Feb '16

18 Feb '16

Hi, I am trying to configure one of my clients to use 'engine = capi', but cannot find a way to define which Key to actually use. debug = 7 does not show engine internal actions and engineCtrl = CAPI_CMD_DEBUG_LEVEL:2 gives an error, as well as engineCtrl = DEBUG_LEVEL:2 I'de appreciate any help with configuring this. Thanks in advance, Shay

User-defined headers to CONNECT
by Jason Whitener 05 Feb '16

05 Feb '16

"Add user-defined headers to CONNECT proxy requests. This can be used to impersonate other software (e.g. web browsers)." My search skills are lacking today apparently. I can't find any documentation or examples about sending custom headers back to the server. Can someone please provide an example or a link to an example? I need to send "WL-Proxy-SSL:true" back to a Web Logic server in the header with each request. Nothing too tricky I assume. Jason

How can I log to file all packet traffic coming from a wss web socket on port 1234 using stunnel, openssl and tcpdump ? I have already seen https://gist.github.com/jeremiahsnapp/6426298#file-stunnel-mitm-proxy-conf , but I would like to know how to configure it

Microsoft Exchange 2010 - SMTP issue
by mahdi＠kadtekautomation.com 04 Feb '16

04 Feb '16

Hey all, Has anybody here been successful connecting to Microsoft Exchange 2010 servers usnig STunnel? Here is what I have in my stunnel.conf: ******************** cert = stunnel.pem socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 client = yes [ssmtp] accept = 127.0.0.1:587 connect = smtp.ex3.secureserver.net:587 ******************* And this is what I see in the log: ******************* 2016.02.03 18:55:14 LOG5[63]: Service [ssmtp] accepted connection from 127.0.0.1:57314 2016.02.03 18:55:14 LOG5[63]: s_connect: connected 184.168.131.205:587 2016.02.03 18:55:14 LOG5[63]: Service [ssmtp] connected remote server from 10.10.10.10:57315 2016.02.03 18:55:14 LOG3[63]: SSL_connect: 140770FC: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol 2016.02.03 18:55:14 LOG5[63]: Connection reset: 0 byte(s) sent to SSL, 0 byte(s) sent to socket ******************* I am quite sure that my server address and port is correct, and obviously the other application is pushing data to stunnel. Seems like what's coming back from server is puzzling. Any help regarding this? Thanks, Mahdi.

They are all stored here: https://gist.github.com/coolaj86/327cee3eee6fc119b389/ Just as you can see, the 3 certificates are named as follows: cert.pem chain.pem root.pem What's the relationship between the above 3 certificates? And the first certificate, i.e., the cert.pem, is the one used for the website https://coolaj86.com/. So, I just want to know why we must the root.pem in the stunnel's conf file?
