I disconnected my linuxbox because of thunders (shutted down only adsl-box, not linuxbox). After the storm, I connected it again, and now Irssi (irc-client) says "Temporary failure in name resolution".
So, it only has problems to look up dns adresses. (I can connect to it using it's ip address, so ip-adresses works?)
Ifconfig looked fine when I checked them, and /etc/resolv.conf looked to be fine also. (Search, and couple ips.)
What should I try?
