Hi All, I am just wondering how come no one ever mentioned Port - Spanning :)This is a well known technique used to direct the traffic of a series of ports in a switch to one particular port. So administrators can sniff on it. Well i know this has nothing to do with your situation as you yourself seem
to be the administrator of the networkJust thought i would chip in with this as its a very well know technique in a switching environment. You can take a look at this page for info on network taps http://www.securityfocus.com/infocus/1594

It can establish an entire bi-directional Telnet session to a target host never sending your real IP and MAC addresses in any packet. By using "ARP Poisoning", "MAC Spoofing" and "IP Spoofing" techniques sTerm can effectively bypass ACLs, Firewall rules and IP restrictions on servers and network devices. the connection will be done impersonating a Trusted Host."and"ArpWorks is an utility for sending customized 'ARP announce' packets over the network. All ARP parameters, including the Ethernet Source MAC address (the phisical address of your network card) can be changed as you like. Other features are: IP to MAC resolver, subnet MAC discovery, host isolation, packets redirection, general IP confict." --- Computing tutorials and general geekiness at http://www.puremango.co.uk
