Re: How to find a changing IP on ethernet network

["Cesar Osorio" <COsorio () awb com au>]

Ivan,

I forgot to mentioned,   if you place a pc in the HUB just run ethereal or
any other sniffer and look for the IP addresses with diff MAC addressing,
if you are lucky, you may caught the packets at the time of the change...

Hello. I have a client with a simple Ethernet network with HUB's
connecting and there is one person that is changing it's IP and creating
conflicts. What would you do to track down that person? i mean, to find
who does that?
Thanks!
Ivan Hernandez
