Packet capture Kalyan 11-28-2007

We have a packet capture from our network which basically showed MDNS
(bonjour), RIPV2, IGMP (v1, v2, and v3), SNMP, RPC, IPv6 (for ICMP
protocol), etc traffic on our network.

We would like to replay these packets in order stress test a wireless
access point. Can any one think of a tool that would help us?

TIA

I use bittwist (bittwist.sourceforge.net). It will do packet
generation from an existing pcap. Also allows for *some* header
editing using a command line tool. Give it a try.

I'm taking my first networking class, the teacher likes this program but
I'm not sure whether it will do everything you need:

The Ethereal project is dead since May 2006. The successor is called
Wireshark (http://www.wireshark.org). I'd recommend to change Wireshark,
because there were several security bugs in the last 1.5 years which are
not fixed in Ethereal and Wireshark hast some nice new features.

cheers

Jens
