[Resolvconf-devel] Bug#514660: resolv.conf not available after when doing if-post-up

[Christoph Anton Mitterer]

Package: resolvconf
Version: 1.43
Severity: important

Hi.

I'm not sure if this is actually resolvconf's fault but at least it
seems to be somehow connected.

The resolvconf hooks are in /etc/network/if-up.d/000resolvconf and I'd
assume from this, that /etc/resolv.conf should be set up already, when
if-post-up-stuff ist executed (and these scripts should already have DNS
available.
But it seems that it's not the case.


I stumbled across this when doing the following:
I wanted to set up iptables rules via pre-up/post-up/etc
in /etc/network/interfaces (using iptables-restore).

Now I think one should be able to assume, that in post-up, DNS is
already available.

I have a special set of iptables rules which is loaded pre-up, in order
to secure the interface, even before it's brought up.
And in post-up I have my actual rules (which also use some hostnames, as
source-addresses or so...).
But this doesn't work, as DNS is not yet available in post-up.

When I move resolvconf's hooks to /etc/network/if-pre-up.d/ it works,
and DNS is available.

Could this be some timing issue? Any ideas?


Thanks,
Chris.
