[Bug 604283] Re: network servers do not listen on 127.0.1.1

[Steve Langasek]

I don't believe there's any bug in ifupdown here.  As mentioned in the
upstream Debian bug, you do not need an explicit 127.0.1.1 network
interface to receive requests on that address, *as long as* you are
listening on the "any" address.  This is indeed what openssh is doing by
default; being able to ssh to 127.0.1.1 has nothing to do with any
ifupdown changes.

Out of the many services I run, the only ones I find that have problems
with 127.0.1.1 are bind, ntpd, and nmbd.  nmbd is entirely
uninteresting, because it's only relevant on broadcast interfaces (which
is part of why it must bind by IP). ntpd's behavior could be considered
a bug, as could bind9.  Since you mention bind9 explicitly, I think
reassigning this report to the bind9 package is the reasonable course of
action here.

** Package changed: ifupdown (Ubuntu) => bind9 (Ubuntu)

** Tags removed: patch
