Trustix ip_tables problems
 

I have set up a trustix machine to be used as a firewall running iptables. I have no other internet services running (other than those used by the system) yet I am having some very bad instabilities. The machine will stay on for about 20 hours and then it will freeze solid not even allowing any network traffic (I can't even ping the internal network interface), the shell won't respond, and the hdd indicator light glows pretty much non-stop. However, if I bounce the machine (using the power button) everything is just fine- for about 20 hours. During boot, I have no problems with the machine receiving its dynamic address from my cable modem and I have no boot errors at all.

I am thinking it might be a driver issue with the nic, but am unsure. As far as I can tell in checking with the BIOS, the system is not overheating. I have kept the system at stock clock speeds as well.

The hwconf file contained the following information about the nic:

class: OTHER
bus: PCI
detached: 0
driver: tlan
desc: "Compaq|Netelligent 10/100 Dual"
vendorId: 0e11
deviceId: ae40
subVendorId: 0000
subDeviceId: 0000
pciType: 1

System specs:

Trustix secure linux version 2.2
kernel 2.4.30
EXT-3 file system
AMD K6 @ 500MHz
256MB ram

Thank you for any pointers you can provide.

ADDENDUM:

I posted this in the Distro forum and someone suggested that it may be the syslog file filling up to the point that it cripples the system. However, I have a 10GB hdd and 256MB of ram on this system. While I am on cable modem and thus have a large amount of ARP requests from the subnet that I am on, I don't have a lot of traffic otherwise. I haven't checked the logs to see if these ARP requests are being logged but I have not explicitly set up logging in my ip_tables.

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.
