[tor-talk] Analyzing the traffic between nodes in my private tor network

[juhapki at wippies.fi]

Hey guys,

I succeeded to build a private tor network including some hidden services in it and every tor-machine (ubuntu) is behind a different router (multiple networks) I have tried to build my tor network as real as possible in our lab environment. Now I am monitoring the network traffic between the nodes and I have realized that all the traffic is just TCP (PSH, SYN, ACK etc.). No sing of client hellos, key exchanges, encrypted handshakes. When I compared traffic between real and private tor networks using Wireshark, there was no TLS-, SSL-traffic in the private one while the debug log file says that there was a bunch of "tor_tls_handshakes". Is it just because nodes in the private tor network have configured differently (TestingTorNetwork, OrPorts and DirPorts port numbers, own auth dirs, etc..), old version of OpenSSL or something else? Any good explanation why the traffic it's just TCP?
