Multicast setting for network sniffer

harold
I have a Linksys WRT54GL router upgraded to the DD-WRT firmware. I need a sniffer program and/or router setting that will capture all PC on the net, not just the one the sniffer is running on.

    Snort is a great sniffer program. Sniffs everything going over the wire.

    You may need to connect all your PCs to a separate hub first so that the PC with the sniffer will be able to see all the traffic on the LAN. The packets in a switch environment get routed from one port to the other, without being broadcast to the rest of the LAN.

    the wired pc and server are not the greatest concern at this point. The first order is to monitor the laptops. I will try the hub for the wired units.
