Yes, the timeout is there sometimes. After the timeout, the login
prompt appears. After specifying (the correct) password, i get
loggind in and immediatly logged out again.

The timeout occurs when i connect from a machine, and dns is set up
but cannot find the machine.
The timeout does not occur when i disable dns (removing or emptying
/etc/resolv.conf)

If you need debug output, just let me know.
