random timeouts


Hi All,

I Run a 80-100 PC network from 4 Fedora Core 6 Servers. They all run fine. I have them on a DMZ together, with one pc as firewall/router.

The firwall/router pc has 3 nics in, one for connection to the internet, one for the DMZ, and the last one is for the public local network.

All the servers have shorewall running for managing connections, seeing as it is easier for me than iptables or anything of the sort.

The problem I'm having is that I am getting random timeouts when someone tries to access SOME network resource through the firewall PC. This is obviously most noticeable when trying to retrieve mail, and the server timeouts, or when trying to browse and the same happens.

This does not seem to be something that has a pattern, some days I get no complaints, and some days it just keeps on happening. I have checked everything, and I cannot find fault.

The NICs have worked for two years before without any hassle. The problem only started occuring when upgrading from FC4 to FC6.

Thanks a lot!!!

tried using ethereal or wireshark to diagnose?

I find when I have servers that are unresponsive that using these tools is invaluable.
