Is that what it's now called?

I have this older version laying about:

isic-0.05.tgz, main credits to Mike Frantzen.

Never found a system I could not crash with that toolset.  Sometimes including the sending system...

Thanks,

Ron DuFresne

I am looking for a tool that can be used to stress the tcp

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,
