You can always run a capture and replay it with fragroute. Man page excerpt: #################### FRAGROUTE(8) NAME fragroute - intercept, modify, and rewrite egress traffic SYNOPSIS fragroute [-f file] host DESCRIPTION fragroute intercepts, modifies, and rewrites egress traffic destined for the specified host, implementing most of the attacks described in the Secure Networks ``Insertion, Evasion, and Denial of Service: Eluding Net- work Intrusion Detection'' paper of January 1998. #################### Cheers, -Chris On Tue, 30 Nov 2004, Dan Lockwood wrote:

Hi all,

I'm looking for a program that can generate "real" looking traffic. It should be able to send TCP/UDP traffic to a large set of hosts (thousands), send traffic to random or semi-random ports and send packets/datagrams that are of random/semi-random size. Ideally it should run on windows or some sort of Perl script would be fine. Anyone have any ideas or should I dust off my programming books?

Thanks, Dan
