While poking and proding around I've found that my particular linksys router is very sensitive to mtu size. I'm running Suse 9.0 which defaults the mtu size to 1500 (as I would assume all other do)upon reboot. Since I'm a slave to sbc dsl, and am living with the 8 byte overhead of PPPOE, my mtu size needs to be 1492. If I reboot the machine, the mtu reverts back to the default and becomes basically useless on the net until I open up a terminal and perform an /sbin/ifconfig eth0 mtu 1492. After that, all is well with the world.
Now, on with the question. What is the best way to automate the mtu change to 1492 or is there a way to just change the default???? I'm attempting to limit my maintenance on this machine in the event that someone reboots it, or the UPS runs to the end of its rope when the power fails....
Ideas???
