I haven't sure if ethereal supports PLC network, I think not.
If PLC in this case stands for Programmable Logic Controller, than I think the latest stable version of Ethereal has support for this sort of traffic. I've never used it though.
Some switches have a port called PROBE PORT that is used exactly for this. All the traffic in the network passes through him. I don't know if Cisco call this port with other name, but....
Cisco call it a SPAN (Switched Port ANalyzer) port or a session monitor port. Casually it's referred to as a spanned port. The 2955 does support it: http://www.cisco.com/warp/public/473/41.html#support Here's how to do it: http://www.cisco.com/warp/public/473/41.html#topic5 If you want to use the monitoring PC on the network, while running a packet capture on the spanned port at the same time, then - as Francois already mentioned - you would indeed need to NIC's. Otherwise one will suffice. regards, -- Lukasz Szmit University College Dublin --------------------------------------------------------------------------- This list is sponsored by: SensePost Hacking, like any art, will take years of dedicated study and practice to master.
