I know, I tried adding disc0, and lo1. But it seems that the *real*
problem with my named answering that he's not authoritative for his own
domains is elsewhere.
Thanks everyone for replying. I have found in the mean time that disc0
can be used for an interface that discards packets, and that one can
have as many loopback interfaces as needed [although I suspect that one
would suffice most of the time].

If you want an interface that loops back, you can have more than
one loopback interface (lo0, lo1, lo2, ...).
If you want an interface that discards everthing, you can create
a netgraph interface ("ngctl mkpeer iface foo inet") and leave it
unconnected.
Or do it with the proper BSD pseudo-device:
# The `disc' pseudo-device implements a minimal network interface,
# which throws away all packets sent and never receives any. It is
# included for testing purposes.

Dummy ethernet interface.
Is there some way to ifconfig up a dummy ethernet interface, one that will work like the loopback one (lo0) on FreeBSD? I'm playing around with a local caching named on a machine that has only lo0 and a ppp0 interface, and bind always replies with 'for authoritative replies ... blah blah' when I use host. I remember that having localhost.my.domain set to 127.0.0.1 and the reverse, but my (fictitious) hades.hell.gr - 10.0.0.1 seemed to solve this problem on linux. I looked through the LINT file in my sources [cvsuped: 7 Jan 2000], but could not find anything like that. Is there such a thing, or the time has come for me to start playing around with my kernel and ethernet drivers? A pseudo-ethernet device seems like a nice reason to start panicing my home PC, but I don't want to repeat other people's work if possible ;) -- Giorgos Keramidas, keramida @ ceid . upatras . gr For my public PGP key: finger [EMAIL PROTECTED] PGP fingerprint, phone and address in the headers of this message.
