Okay... Firstly, sorry for the delay in the reply (I have been moving
house). Secondly, yes I can ping 127.0.0.1. If I let it ping 192.168.1.1 (my
other machine), I get the error message:

NETDEV WATCHDOG: eth0: transmit timed out
eth0: transmit timed out with status 0040, network cable problem?

The route output on my LFS system is:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0

The route output on my Redhat system is:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
127.0.0.0       *               255.0.0.0       U     0      0        0 lo

I hope this helps

Thanks
