Hello,
Im doing something realy stupid on a new server, and it will not resolve! My network settings are pasted bellow. It will respond to a ping, i can access it using ssh. The nameserver IP's are correct and working! Gateway ip is correct and working.

Many Thanks!

In /etc/resolve.conf:

nameserver 212.23.3.100
nameserver 212.23.6.100

In /etc/sysconfig/network

# ps -A | grep sshd
2996 ? 00:00:00 sshd
27138 ? 00:00:00 sshd
27140 ? 00:00:00 sshd

ssh works fine! Its resolving that fails!

Do you mean that DNS resolution from that machine, i.e. dig www.google.com, fails? If you can ping the DNS servers from that machine, then the problem may be the firewall.

Yes, dig on that mashine does fail. And it will not let me ping the DNS servers, but all the other mashinse on the network will let me ping them. Firewall is below:

;; connection timed out; no servers could be reached

Fire Wall: (default from setup)
