Hi Kerry. Wouldn't increasing the mtu value decrease over head? Because I am trying to raise the value to 10000 or something, not lower it.

I put mtu 1000 after the line where it says iface eth0 inet dhcp. I restarted inetd and init, and the value hasn't changed. Does anyone know how to go about doing this? Thanks!
