ssh freezes

[cybermans]

When I (and an other guy) connect to my box and try to use by example the command ls: it freezes. Nothing happens anymore.
sometimes I get to see the first line and when the directories are small enough it shows it completely but most of time nothing.
This happens also when I try to use by example cat somelogfile or nano -w someohterfile.

Anyone has a suggestion or a solution cause this drives me nuts.

Since SSH is a stateless protocol it can indeed lose the connection, but usually after a certain inactive time and definitely depending on the client used - smart clients send keepalive packets.

Try to increase the logging level for sshd and do a few more runs (I am assuming that you have already looked at the logs you get now.)

Hmm, this is definitely wrong - some strange mix of IPv4 and IPv6 address...
