SOLVED:
the local hostname wasn't listed in /etc/hosts; you can add every host 
in the lan, but when the localhost isn't listed with his name, the whole 
name resolving isn't working properly - in this case.
I don't know if this is an iussue of diablo or the java vm, because for 
a while a java XMPP client was running on this machine without problems.
