As I recall RedHat is known for not putting a proper entry for it's own name in /etc/hosts, so check this. Also check the output of the 'hostname' command. Then check that the entries in /etc/resolv.conf point to the right dns-servers, either your internal dns-server(s) or your isp's. regards, -- Paul Schoonderwoerd Pollux IT - Open Source & Netwerkbeveiliging tel: 0294-283832 http://www.Pollux-IT.nl
