I have experienced many system hangs in the last few days even after applying the IP Frag patch.. I found out the reason that I got a system hang when someone used "smurf" to attack the machine .. it was getting icmp echo replies from about 500 different hosts about 17megabits/sec . as SOON as the eth0 went up the machine would lock up.. it wouldn't even finish booting because as soon as the eth0 was activated it would dead lock. Is this a problem with the kernel or a problem with the 3c90x.c driver ? Kernel 2.0.32 pre - 5 with ip frag patch K6 233 128MB ram 3com 3c905 100BTX Card PCI It's on a 10 megabit non switching hub right now. Is there any way to specify the mode of the card during bootup with lilo? Can I disable bus mastering? Any ideas on what would cause this??
I finally found a way to make it lock up every single time by sending this stream of data.. Any ideas would be appreciated!
