I suspect (after ruling out having a warez distro site on the box) the latter. Our uplink provider monitors traffic for us and the spikes are there - it's not that our uplink switch just stops working (as it would if too many packets per second came in), the traffic really is there. So my wild guess was that we were just ping -f'ed, stacheldrahted or something like that. --ck -- php development | hosting | housing | professional game server hosting http://www.de-punkt.de [ chris(at)de-punkt.de ] http://www.stormix.de +49 511 1237504 | +49 511 1237505 | laportestr. 2a, 30449 hannover.de Filoo auf dem Linuxtag 2003 (F15) - http://www.de-punkt.de/lt2003.php ---------------------------------------------------------------------------- Attend the Black Hat Briefings & Training, July 28 - 31 in Las Vegas, the world's premier technical IT security event! 10 tracks, 15 training sessions, 1,800 delegates from 30 nations including all of the top experts, from CSO's to "underground" security specialists.
