Hi All, I have a coupla queries about my 2 latest installs of CentOS 4-3. When I first installed and logged in as the initial user, everything went well, and the system was fast. A reboot, and 2nd login gave the same. But, upon connecting to the net, the system hung at sendmail for almost 4mins, and then gave an error at login about not finding the host, and that Gnome may not work correctly, with options of Continue or try Again. After that, the system has become extensively slow. Any ideas why this would be this way? This is the 2nd machine, different locations, different media, that this has happened. Rather annoying. Cheers. Mark Sargent.

Cheers.Do the affected boxes have a proper hostname? cat /etc/sysconfig/network I seem to recall seeing that gnome complaint under such circumstances... -Andy -------------- next part -------------- A non-text attachment was scrubbed...

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
