Log to file WSS Websocket packet traffic
by Francesco Alfano 05 Feb '16

05 Feb '16

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.

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?

This seems to perfectly match the 'conventional meaning of the log level' used for most POSIX system log daemons (e.g. the linux syslogd). I don't know how significant the level /names/ actually are - Maybe all you can read from this is that level 0 gives the fewest and level 7 gives the most messages.

Fwd: Stunnel log file format
by Jesús Alfredo Cambera 12 Jan '16

12 Jan '16

Hi everybody, I'm pretty new on stunnel and I'm still learning a lot through the documentation. One of the tasks that i need to accomplish is to consolidate all the log information using logstash and ELK. So far I had managed to figure out most of the log file format. Here is an example of my log file 2013.01.11 11:26:35 LOG5[13520:140223486400256]: stunnel3 accepted connection from 127.0.0.1:45939 2013.01.11 11:26:35 LOG6[13520:140223486400256]: connect_blocking: connecting 123.4.5.6:9130 2013.01.11 11:26:35 LOG5[13520:140223486498560]: connect_blocking: connected 7.8.9.10:9130 The first two fields are date and hour but I don't understand what do the next field means (LOG5, LOG6). Next is the pid, but I don't know anything about the next field. The last one is the error explanation. Is there documentation about log file format? I'd really appreciate your help. Greetings from Venezuela, Alfredo

Thank you for your fast response, Jhon. My target https-server is a Synology DS211+ with Apache 2.2(Unix). Its VirtualHost config looks like: <VirtualHost *:443> ServerName myhost.mydomain.com ServerAlias internal.name.local DocumentRoot /somepath/not/used/at/all/ SSLEngine On SSLProtocol all -SSLv2 -SSLv3 # TLSv1 or higher SSLProxyEngine On ProxyRequests On ProxyBadHeader Ignore ProxyVia Full AllowCONNECT myInternalPort <Proxy *> Order deny,allow Deny from all </Proxy> <ProxyMatch (internal\.name\.local)> Order allow,deny Allow from all </ProxyMatch> LogLevel debug ErrorLog /logpath/sshserver-proxy_error_log CustomLog /logpath/sshserver-proxy_request_log combined </VirtualHost> The sTunnel client config on Win7 is: debug = 7 log = overwrite output = C:\userpath\stunnel\stunnel.log socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 client = yes [http-2-ssl] accept = 127.0.0.1:80 connect = proxy.gateway:gwPort protocol = connect protocolHost = myhost.mydomain.com:443 retry = yes config = Protocol:ALL config = Protocol:-SSLv3 Finally still remains my initial question: Can I wrap my http-proxy request into http over ssl (https) and receive it on an Apache https server? If 'yes', how? Best regards Hathor27 Btw: Hopefully better posted
