That is correct.

Partially correct. The management port is indeed 25061, but by default  
it also uses TLS. However this one you can configure to use TCP if you  
want.

Unless you use a port that is not the default (25060) there is no need  
to specify it, it's enough to specify the IP. However it's not  
incorrect if you specify it.

Yes it can, however if the communication is TLS, you won't see  
anything meaningful, other than the fact that they exchange packets  
since the communication is encrypted. But if one endpoint uses TCP,  
you will see in clear what it sends in the wireshark trace.

In python-gnutls, in the examples directory are some scripts. Can you  
run twisted-server.py and then twisted-client.py and see if they can  
communicate? Just to rule out problems with the gnutls library.
