Hi,
Please pardon me if I am sending this mail to an inappropriate mailing list.
I have a setup where a Linux machine (2.6-test9)intrusively sits between the
campus netwok and a cisco router that connects to the Internet. The network
traffic pass through one one ethernet interface, get processed more on the
lines of a firewall, and sent out on the other interface. The packet processing
happens at the user level. I am using realtime support and enabled kernel
preemption flag for the kernel image.
The problem is, whenever there is a network flood either syn or icmp or any
other kind, the Linux machine goes into a funny state and the first symtom is
I cannot compile any program. The filesystem gets corrupted. Any amount of fsck
doesn't help. The only way I come out is reinstalling Linux. I have tried RH,
and Debian the distribution did not matter. There is nothing wrong with the
basic hardware because the system works fine in the ideal network conditions.
So, I have no clue whether it has to do with network handling, or something to
do with the filesystem support or something else.
Have you encountered this kind of problem ? Or am I the only one :)
I know the group loves to discuss the in-depth core coding issues, but I need
help in isolating my problem.
Thanks.
Anand
