The Network device shows:
eth0
lo
lo
If I telnet from hcomp5 to hcomp8, I appear to have a loopback problem, 
and get:- 
Trying 192.0.0.8
Connected to hcomp8
Escape character is '^]'
Redhat Linux release 7.0(Guinness)
Kernal 2.2.16-22smp on an i686

I have very little network experience, but assume that 'lo' should not be 
an alias for eth0, but of course it cannot be edited.
If I select eth0, from the aliases for virtual hosts screen, then the next 
screen shows every field blank.  
netstat -rn shows: 192.0.0.0  0.0.0.0 255.255.255.0  U  00 0 lo
                   192.0.0.0  0.0.0.0 255.255.255.0  U  00 0 eth0
I assume that the 'lo' line should show 127.0.0.0





Also  netstat -rn shows:-  


Reproducible: Didn't try
Steps to Reproduce:
1.I believe that all setups for networking were made using linuxconf. 
Presumably there is a file which could be edited in order to clear the 
eth0 and lo entries, and then attempt to reproduce the problem by by 
repeating a setup using Linuxconf.
2.
