Or are there other things I need to do? From the desired MTU size I guess you are trying to play with VLAN tags ? Yes, instead of mucking with kernel code, you can do it with the 'ifconfig' tool too. I do use that when I need to do things like that. In RedHat 7.1 /etc/sysconfig/network-scripts/ files there are no provisions to do the MTU setting explicitely for Ethernets. You can create the effect by looking at how ifup-ppp does it, and applying the thing into the basic ifup. > TIA > Avichai /Matti Aarnio - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
