[Bug 959037] Re: NM-controlled dnsmasq prevents other DNS servers from starting

[Alkis Georgopoulos]

I'm still having problems with this on 14.04.

After the default installation, I installed dnsmasq and DNS stopped
working until system restart.

Now it's only working for a few seconds after each network-manager
restart!

If I comment out
#dns=dnsmasq
in NetworkManager.conf, then everything is fine again.

For the 500+ schools that we're supporting here, we'll just continue commenting out #dns=dnsmasq because it doesn't cooperate with the regular dnsmasq installation,
but if you want me to provide more info to troubleshoot this issue, I'd be glad to.


I'm attaching the output of nm-tool. My effective dnsmasq.conf is:
