Hi David Walcroft!
Scanning the thread it sounds like you have a DHCP server set up to
run from Eth1 which is connected by a crossover cable to Eth0, which
sets up to be 192.168.0.1 -- then when Eth1 tries to be 192.168.0.1 it
cannot since that is already taken.
If the above is correct you need to edit your DHCP server config files
to create the network you describe (Eth0 ...2 -- Eth1...1).
As a quick check you might try setting both ports to the separate
fixed addresses and see if ping then works.
The only other thing that occurs to me is that many of the error
messages sound like those I would hear from SELinuix - are you running
a security environment such as SELinux and is it in enforcing mode??!
Good Hunting!
Tod

Can someone tell how to get over this error please
[david@reddwarf ~]$ sudo service network restart

Error, some other host already uses address 192.168.0.1.
How do eth0 and eth1 get their IP addresses?
From dhcp?

What do I do to get ping to work and is it part of this problem overall.
192.168.0.2 is on the other end of my crossover cable
Thanks david
