As i showed in my mails, there was just nothing in the routing table,
yet all my attempts to ifconfig an interface yield a ``File exists''.
(I wouldn't have asked otherwise, trust me. :) It is totally benign,
in that the correct routes are being added nevertheless.
Probably i need to CVS update again.

uriah # ifconfig bppp0 193.101.57.{162,161}
ifconfig: ioctl (SIOCAIFADDR): File exists
(Surprise)
I think it happens for all p2p interfaces only, never for ethernet-
type interfaces. It regularly happens when setting up a SLIP
interface, that's where i noticed it first.

Never trust an operating system you don't have sources for. ;-)
