Hallo, Amos, Du meintest am 19.10.10: > Turn of "offline_mode" if you have it set in squid.conf. Despite the > name, it only causes aggressive caching to be done. But what shall I do with a squid installation in a boarding school ("Internat", many pupils have their own computer(s)) where the connection into the internet is cut from midnight to 6:00? "squid" mourns on and on that the DNS is unreachable (and that's right ...). Viele Gruesse! Helmut
