What type of traffic is it? (transport layer protocol, as well as application protocol -- ex: HTTP is TCP port 80) Are there any DNS queries that happen prior to the spike? Use wireshark to capture them and that might give a clue. You could also use nethogs to diagnose and determine what program is causing the spike. http://nethogs.sourceforge.net/ -- ---~~.~~--- Mike // SilverTip257 // _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
