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

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.
