[rhn-users] A critical Problem wirth NIC

[Aboobacker (Network Admin.)]

Dear Paul,
Thanks for your reply. I can't use the dhcp server because for the proxy
users we are configured restricted thru static ip address. So, I can't
use this step. After the disturbed that sever then only I can see who is
done thru the arpwatch. Please any other solution could you provide. 
Thanks and regards,
Aboobacker

If I understand your situation, you have a bunch of machines with static
IP
addresses, and one of your users on your network is picking one of the
addresses of your server's IP address.

You might try using arpwatch to see whether you can catch the MAC
address of
the conflicting machine.  If you can gain access to the switch, you
might be
able to track it there as well.

Can you prevent your users from changing their IP addresses?  Set up
dhcp for
the user machines? 

Paul
