on Redhat 9.0 linux , The mail stop working suddently and also if I try to run SETI it gives me the gethostbyname error, this was working great for like 1/2 years and then stopped working. How can I fix it ? However I can still get into the machine from the outside via ssh and samba works also. If I try to ftp/telnet from the linux box to the outside world it just hangs, but ping would work just fine.

Any clues ?

Thanks

Check /etc/resolv.conf and make sure that it has a valid name server IP listed, something like:

nameserver 1.2.3.4

I have this :

; generated by /sbin/dhclient-script
nameserver 192.168.2.1
search localdomain


It looks like it's using the wireless router as the nameserver right ?

I changed that 192.168.2.1 to 206.13.29.12   and now everything works. Now I wounder if that ";generated by /sbin/dhclient-script" will switch it back to the 192.168.2.1 and screw it up again! Do you know if that's the case ?

Unless you fix the wireless router's config so that it furnishes a valid nameserver IP the problem will reoccur the next time DHCP negotiation happens, assuming that the wireless router is assigning and IP to the system via DHCP. The other possibility is to include "PEERDNS=no" in the interface control file for the NIC in /etc/sysconfig/network-scripts
