connection to aol- need to change mtu to 1400?

sonichedgehog · 03-02-2008, 06:28 PM

Trying to break my friends' dependency on windows will require aol connection. They have broadband. Research indicates mtu change to 1400 from present 1500 is required. I can see the mtu in gnome-nettools but can't "configure" as no dialog requesting root authority comes up. What please is the terminal method? Thanks-Phil

You can use ifconfig to set the MTU (there's more info in the man page). For example, to see what the MTU is set to for the eth0 interface:

Code:

ifconfig eth0 | grep MTU

To set the MTU (with my version of ifconfig):

Code:

sudo /sbin/ifconfig eth0 mtu 1400

You can run this from the system start up scripts so it gets done every time the box is booted (you won't need sudo to do it from the system scripts).

Thanks Steve, never modified bootscripts before but there's loads of info out there, I'll see how I get on and post again whenits sorted (being positive here!)
