"File exists" is, I think, a generic translation of an error code. "ip" is trying to create a default route and is told, by the kernel, "that route already exists: EEXISTS". "ip" then passes "EEXISTS" to an error code translation routing which spits out "File exists". To cut a long story short, you can't add a default route if you already have one (well, technically you can, but you'd need to provide more information). You probably have a default route sending traffic over eth0. > > Does anyone have a clue what may be wrong? > > And 5 years after I had a big fight with RTNETLINK, whatever the heck > that is, it is still keeping the cause of the error secret. > > So, net experts, what do I do? > > Thanks. > > Cheers, Gene Heskett
