I am using Pidgin on Ubuntu 12.04. The university network blocks (I think) port 5222 for XMMP connections. I thought about using Tor to circumvent that. I installed Tor and configured pidgin to use it. Facebook connects fine but gtalk says "unable to connect". Any idea what is wrong? The configuration is otherwise good, I know it works onother networks.
Do you know about any other means to circumvent blocking of port 5222 for accessing gtalk?
