    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.
