1. Yes i can ping 127.0.0.1
2. Yes each card can be pinged, ie. 
192.168.0.1 (eth0)
192.168.0.2 (eth1)
however if I try pinging one from the other, ie.
ping 192.168.0.1 -I eth1
I get network host unreachable

I gave the ip forward thing a try but that didn't help.
basically the set up is that both cards are on the 192.168.0.0 network
with a netmask of 255.255.255.0  Dont get too worried about me having
the two cards in there and the problems with that, see I've just put
them both in there to test it, the initial problem was that if one card
was in there with the exact same settings as another rh6.2 box, it still
couldn't ping the network, so i've been swaping cards and changing isa
slots and even changing distributions, and nothing seems to be working.
