cannot ping external ip but can be reached from outside

[keak]

Hi there,

I have a server box where I can reach from outside Internet;
but when I try to ping to say yahoo.com from within the server, I get a host not found.

I believe its either a iptable rule or its pointing to a wrong name server. does anyone know where a name server is sepcified, and also, how one can backup/clear all existing iptable rules?

thanks!

just to be clear,
I don't seem to even hit my gateway when I do a traceroute ...


$ traceroute yahoo.com
traceroute: unknown host yahoo.com

ping yahoo.com should lead to the same destination as

ping 66.94.234.13

You may use the latter to verify it's a nameserver problem.
The nameserver is normally specified in /etc/resolv.conf, but is often configured on startup with /etc/init.d/network, ifup - very distribution- and hardwarespecific.

route

If you have a gateway, you would say:

route add default gw 192.168.x.y

or what the ip of your gateway (router) is.
