What in the WORLD is using so much CPU.. we are getting a denial of service attack about 100,000 packets per second and the router is 100% cpu, then when I do iptables -t mangle -I PREROUTING ..etc.. -j DROP to match the packets and drop them the CPU drops to like 15% ... so my question is #1. What in the world uses all that cpu simple routing packets in one interface and out the other? #2. What in the world uses 15% cpu simply blocking packets in the prerouting chain? I'm using NAPI and e1000 so i don't see how it could even possibly use 15%
Any ideas on how to debug or find out what's causing this? Thanks _______________________________________________ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
