Hi Brian

Yes, very helpful. You describe exactly what you did and what the result was.

It's especially useful to know what one of the causes of the problem was. :)

Bind9. I'm not surprised.

In #9 I wrote "when NM is in 'dns=dnsmasq' mode you will only see 'nameserver 127.0.0.1' in /etc/resolv.conf." That wasn't entirely true and you have proved it! What's true is that when all interfaces are managed exclusively by NM and dns=dnsmasq then 127.0.0.1 will be the only address listed.

That you have additional addresses listed in /etc/resolv.conf indicates that something is still wrong. You wrote earlier:

> The VPN DNS servers are in /var/run/resolvconf/interface/NetworkManager and /var/run/resolvconf/interface/ppp0.

There is something wrong here. The addresses should not be included in *both* these files.

Can you please reboot and reconnect to the vpn and do "ls -l /var/run/resolvconf/interface/" again? Also post the contents of each file in that directory.

If you still get both /var/run/resolvconf/interface/NetworkManager and /var/run/resolvconf/interface/ppp0 then there is a bug somewhere.

How do you bring up the VPN? With NM? OpenVPN or PPTP? Which vpn package or daemon?
