Back in July we added the ability to drop local dnsmasq config into /etc/NetworkManager/dnsmasq.d which is part of NM 0.9.6, released in early August. I believe this fixes your problem. The reason we cannot use the normal dnsmasq configuration is that by default, that gets read, but there's a *lot* of stuff that uses dnsmasq these days (libvirt, manual installs, NM, etc) and NM's use of dnsmasq is quite different from these others, and thus the configuration directives in the default config file simply don't apply to how NM uses dnsmasq. I think your best bet is to either: 1) get Ubuntu to backport the patch (git commit ac152ece0206b4cde28acf78abb21518e67513e1) to 12.04 2) replace dnsmasq with a shellscript that checks the arguments it's being called with, munges the arguments, and then calls the real dnsmasq Dan ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
Re: [Dnsmasq-discuss] How to add local configuration to Network Manager initiated dnsmasq in Ubuntu 12.04
Strange. I installed 12.04 from scratch, and had to install dnsmasq and change it in the NetworkManager. In fact I finally fixed an issue with the Ubuntu machine itself not resolving names outside itself (ie Internet DNS) by changing the line to dns=dnsmasq,dns Thus the default on a new install was dns not dnsmasq. I will check the workstation I upgraded to 12.04 later tonight. - Jay Sent from my iPhone On Oct 9, 2012, at 4:39, Chris Green c...@isbd.net wrote: On Mon, Oct 08, 2012 at 06:49:38PM -0400, Jay Imerman wrote: On Oct 8, 2012, at 14:04, Chris Green c...@isbd.net wrote: I have run dnsmasq with local configuration for quite a while now to provide local DNS services on my home LAN.
