This can be a godsend or a huge problem but check it out

www.lookatlan.com

the program runs great on one system but buggy on another....but it can definitly help as it crawls the network, shows IP's for all systems connected and a bunch of other info, and its free!! Had a tech who forgot to disconnect his VPN form home and it showed his IP information and computer info. He says he is behind a firewall....nice to see if someone is connecting through a back door and the program refeshes every so often and alerts or even emails changes on the network!!

If you want an industrial strength IP packet monitor, try ethereal, it's a free monitor released under the GNU license. Very complete and powerful.

ethereal on RH 8.... mmmmm.... :yes:

I don't think it's a packet monitor - more of a ping and port scanner .... like NMAP
