The fix for this issue caused another regression, dnsmasq now doesn't
function correctly as a tftp server either.
I just tried Trusty (dnsmasq 2.68-1), and network manager ships
/etc/dnsmasq.d/network-manager with:
bind-interfaces
So now dnsmasq only binds 127.0.0.1 for its tftp service:
udp 0 0 127.0.0.1:69 0.0.0.0:*
954/dnsmasq
udp6 0 0 ::1:69 :::*
954/dnsmasq
...and of course that breaks everything. Removing that file makes tftp
work again.
Mathieu, could you please package the modifications to
/etc/NetworkManager/NetworkManager.conf and to /etc/dnsmasq.d/network-manager
as a separate, network-manager-local-resolver.deb package, maybe even produced
by the network manager source code, and Recommented: it from network-manager,
...so that people that want to use dnsmasq as a real server can just
blacklist it without suffering on each new Ubuntu installation?
E.g. for the 500+ schools we maintain here, we could then just Conflict:
network-manager-local-resolver from our main package and forget the
whole thing...
Thanks,
Alkis

Bug description:
As described in
https://blueprints.launchpad.net/ubuntu/+spec/foundations-p-dns-
resolving, network manager now starts a dnsmasq instance for local DNS
resolving.
That breaks the default bind9 and dnsmasq installations, for people that
actually want to install a DNS server.
Having to manually comment out "#dns=dnsmasq" in
/etc/NetworkManager/NetworkManager.conf doesn't sound good, and if it stays
that way, it should be moved to the bind9 and dnsmasq postinst scripts.
Please make network-manager smarter so that it checks if bind9 or
dnsmasq are installed, so that it doesn't start the local resolver in
that case.
