If I'm trying to connect to another local machine with ssh, my system goes online since ssh fails to locally resolve the address of the other machine for some reason.
Does someone else have this problem? The address of the other machine is in /etc/hosts and it can also be resolved by the local DNS without problems. /etc/nsswitch.conf contains the line "hosts: files dns". Reverse DNS lookups do work. I can use other services like ping and telnet without the described problem.
