Thanks Greg, baretail is brilliant and free, uses virtually no CPU and very
low memory. Run this on your IP logs, set up some color highlights for your
internal networks, then bingo, you vcan see a Nachi machine strat up just
like that, low tech but it works.
Cheers

There is a command. I remember using it for just this reason. I know it is a
tail.exe because its on my system, but I cant for the life of me remember
where it came from. I thought it may have been part of the pstools suite
from sysinternals but its not.
I will try and dig it out and let you know.

Jim, yep, I can confirm that HYPERLINK
"http://support.microsoft.com/default.aspx?scid=283213";
\nhttp://support.microsoft.com/default.aspx?scid=283213 works great. But
don't do the first one :) Also, once you have done this you can see in the
logs very quickly which host the attack is coming from, just wish Windows
had a tail command, I tried Wintail but it goes to 100% CPU, anyone know
anything that works well, so you could watch the tail end of the packet log
and see straight way what is happening, like 100 denies for ICMP from one
internal host in under 1 second = Nachi (most likely).
