RE: DoS "Probing" on one of our hosts

["Donald Voss" <voss () albany edu>]

Hello Chris ..

Not to be a jerk .. but could it have been a file sharing app or two or
three ..
a rooted box .. = warez ftp ? You never know until you look close. We have
had students here do the file sharing thing .. then of course everyone sorts
the hits by speed .. then queues up a few hindered .. so our pipe has been
filled from outside connections .. can anyone say packeteer ..

regards,

/don



chown -r us:us /yourbase/

Uhm, I'm quite positive that 97.8 mBit coming in through our uplink are
a pretty good indicator for an attack.

And by "probing" I meant that maybe the attacker only tried to determine
our maximum bandwidth for a larger-scale attack, since the DoSes stopped
fairly soon without any outer influence.
