I am looking for a tool that can be used to stress the tcp implementation
on our web/application server. I remember there used to be a tool called
EvilTCP that could be integrated
into the bsd/linux kernel to emulate a bad TCP implementation. However I
cannot find it on google. Can anybody help with this or do you know of any
similar utility that I can use to make malformed TCP transactions
(request/response).

Not sure if this is what you are looking for, but the ISIC tools
collection (and namely TCPSIC) can flood your server with bad TCP fragments.


If I recall, having played with those years ago, if used aggessivly, and merely mildly aggessivly, there was not a TCP stack we could find that did not get hosed to a state requiring a reboot to recover from. Those are not tools to be played in production envs fer sure.


Thanks,
