- From: mohan34u@xxxxxxxxx (Mohan R)
- Date: Wed Oct 17 14:41:33 2007
I attached the typescript file. please find outputs.
Are you sure eth0 is the correct interface?
Is there any interface other than 'eth0', 'lo', 'dummy0' or 'bond0'? because
dhclient used only these three interfaces.. the output of dhclient is here..

# ping 192.168.1.1
but It failed to detect the server.
1. What do you mean by "failed"?
2. Never describe the end result! It doesn't help in troubleshooting.
Post the output/error/log messages.
the ping output is here..
