Hi,
/etc/resolv.conf may have this header, because at some point resolvconf
was installed on your system. If resolvconf is (or was) installed, the
main /etc/resolv.conf file is a symlink to some autogenerated file
(/run/resolvconf/resolv.conf). This autogenerated file is created
because resolvconf wants all local apps (except) dnsmasq to use dnsmasq
as DNS server. It is NOT used as upstream server by dnsmasq, it is for
downstream programs on local machine (like ssh, mail server,...). Plain
simple?
So in short, your /etc/resolv.conf is correct. If you dont have
resolvconf package installed (check with 'dpkg -l | grep resolv') it is
a relic, but the contents are correct.
The upstream resolver used by dnsmasq is also maintained by resolvconf
(if enabled) and passed via command line. It is also in the
/run/resolvconf folder. If you don't have resolvconf pkg installed, you
HAVE TO add your own "resolv-file=<filename>" or "server=ip" to dnsmasq
config file, otherwise it won't work. There's no default on Ubuntu.

With the default /etc/default/dnsmasq file on Ubuntu it says:-
# If the resolvconf package is installed, dnsmasq will use its output

# Note that including a "resolv-file=<filename>" line in

# installed: the line below must be uncommented.
#IGNORE_RESOLVCONF=yes
I'm pretty sure I don't have resolvconf (or openresolv) so, in this
case how does dnsmasq find the upstream servers. /etc/resolv.conf is :-
# Generated by resolvconf
nameserver 127.0.0.1
search zbmc.eu
Which is a bit odd since I don't have resolvconf.
The system works OK, DNS works, but I'd like to know how.
