I just noticed that I can't bring up a dummy1 interface. Confirmed this with 2.6.9-1.667, 2.6.8-1.541smp and 2.6.8-1.521smp. Dummy0 works fine. Unfortunately net-modules.txt doesn't have any info. If anything I was hoping to be able to add more than two dummy interfaces. I suspect that this is a 2.6 change as I can't find any 2.6 box that will let me bring up a dummy1. Anyone have any details on this it would be appreciated, will be scouring the kernel archives. Regards, Ted
