Hello everybody, yesterday one of my webservers refused to deliver any more webpages, while reaching the server with ssh was fine and the load of the server was very low. But there were 100 apache processes, which is the configured limit on that server. Usually there are about 30 apache processes. In /var/log/messages I found some messages like this at the same time: Nov 19 14:38:12 server1 kernel: TCP: Treason uncloaked! Peer 87.160.97.54:2560/80 shrinks window 1710186274:17 10191335. Repaired. Does anyone know what this means and how it might be related to the apache processes? Ist this some kind of DoS attack? cu, Magnus -- Carl Magnus Rosenbaum M.A. Administration - Programmierung - Weiterbildung http://cmr.cx/ Tel: +49 89 70066626 Fax: +49 89 70066686 Mobil: +49 163 7006662 PGP Fingerprint: DEBC 3C99 EF1D 74F0 D4C7 EFF5 C268 3690 0EA1 7641
