Subject: [gentoo-user] packets with bad cheksum
Date: Wed, 8 Dec 2004 10:43:39 +0100	[thread overview]
Message-ID: <2ab8d39a04120801436357c3b@mail.gmail.com> (raw)

Hello everybody!

I recently tracked down a problem with my home server.
After running for few hours, all connections start to work faulty (no
connections or slow).
When I run iptraf I see that
approx. 30% of all packets  are classified as BadIP (bad checksum in
header right?).
That concerns all intefraces (WAN, home LAN and even LO!!!!).
Reboot helps but the problem returns shortly.

I've booted form a memtest image and run memtest all day and night.
All tests came out clear.

I have  kernel  2.6.8.1 with some patches (grsec,ip_accounting,imq,...),
but It ran flawlessly for more than a month.

The question is: how the hell can I debug it? Any hints?
Memory is tested and I am quite stucked. I've put down squid and
replaced named with nsd temporarily to
eliminate any CPU & MEM eating daemons -- didn't help.
 
No kernel pacnis, no kprintf's .. nothing in my dmesg ... bummer ... :(
