I have setup IPCop and am seeing that I am taking errors (at about a 50% rate) any Idea how I can adjust the MTU rat which is currently set to 1500?

You can do it with either the 'ifconfig' or the 'ip' commands. To see your current MTU setting, use either the 'ifconfig' or 'ip link list' commands (you need to be root for the latter); to set the new MTU, use one of the following as root:

# Assuming that you want to set eth0
ip link set dev eth0 mtu 1400
ifconfig eth0 mtu 1400
If you want to make this a permanent adjustment, you need to set it up in your config files - '/etc/network/interfaces' in Debian, or '/etc/sysconfig/network-scripts/ifcfg-eth0' (or whatever device you're tweaking) in Redhat and such.

You're welcome, Jesse. For future reference, please - don't send us HTML and don't top-post. Reading "Asking Questions of The Answer Gang" at http://linuxgazette.net/tag/ask-the-gang.html is also highly recommended. :)
