trapping packets
 
what i did is enabled packet forwarding and then made my system a router. can i now trap the packets passing thru me and how?

What do you mean trap them? Do you just want to see them with something like tcpdump/ethereal?

mohit_garg 07-10-2005 05:08 PM
trap mean i want to redirect hem into some other file for further dissection?

You can have tcpdump log to a pcap file.

mohit_garg 07-10-2005 05:14 PM
what is it? could u explain?

tcpdump is an application, you sniff traffic with it. You can tell it to match a specific type of packet (or all) and log them to a pcap file, then you can open that file later with tcpdump, ethereal, etc and analyze them.
