You didn't give it the interface name, and I wouldn't change it that way
anyway, I'd edit /etc/sysconfig/network-scripts/ifcfg-ethN where N is the
eth0(1,2,etc) number and set it there. But that advice is for an FC
system, no idea if its valid for kubuntu as my kubunto box isn't powered
up at the moment. Its out in the workshop, cold.

Don't know. ISTR the only place I have a 1492 setting is in the routers (a
linksys BEFSR41 here) advanced->filters setup page. Once it gets this side
of my router, everything is back to 1500 and I'm having no problems
because of that.
