Installed second NIC; now first is screwed up - help

[Don]

Hi,

Relatively new Fedora Core 3 box.  I have one NIC installed on the external
(internet) interface.  Installed a second NIC for my internal interface;
then my problems started.

1) destroyed /etc/hosts; I had to rebuild it
2) destroyed /etc/resolv.conf; I had to rebuild it
3) For whatever reason, decided to make eth0 now eth1 and vice versa - I
think I have it straightened out.

Now when I ping other machines (or the same machine) on the current network,
it pings fine.  When I try to ping an internet site, it hangs for a while
and then tells me, for example:

Ping: unknown host: yahoo.com

Thanks,
Don
