> What is port 2703 ? Nothing special. Well tor seems to be assembling quite some networking infrastructure. Utility http servers like privoxy or eisfair (used with TOR) can be configured to connect through unusual ports. Astaro anti-spam update also used port 2703. If you really need to track it install wireshark. Or use simple commandline tools like ps, ping, whois, nmap.
