I found a solution on stackoverflow thanks to @kbenoit there. https://askubuntu.com/questions/117899/configure-networkmanagers- dnsmasq-to-use-etc-hosts This is not really a bug at all.

I should have written more in my previous message. Having a local lightweight DNS server configured by default, even if it does not respect `/etc/hosts`, may be seen as an opportunity. Don't force it to use `/etc/hosts`. Just configure it by adding to `/etc/NetworkManager/dnsmasq.d`. This means we can add wildcards, which isn't possible in `/etc/hosts`. This is pretty awesome.

I'm on Ubuntu 14.04. This is affecting me. I'm sharing my wifi connection. The problem is that there's a server that has to be queried from a DNS outside of my normal one, but since dnsmasq is using default DNS servers set by dhcp, the devices behind this shared wifi connection can't connect to that specific server. I need to add a line to dnsmasq configuration, such as server=/this.specific.server/specific.dns.ip I found no way to do it and even trying to send a message with dbus did not work (for me). Probably I could not sort it out. I have the specific server ip hardcoded in the /etc/hosts file. If dnsmasq respected the /etc/hosts file, then the hosts behind the shared wifi connection could have obtained the right ip address for the server.

I just did a fresh install on 2 laptops that were working fine with version 12.04. Both laptops have this issue with version 12.10. I've tried commenting out dns=dnsmasq in /etc/NetworkManager/NetworkManager.conf and creating a wrapper script for dnsmasq that removes the --no-hosts option. Neither of these suggestions worked and the wrapper script caused the system startup to hang. I've read comments that the dnsmasq functionality has been part of Network Manager since version 12.04; however, I didn't see this problem on 12.04. It seems that something changed with 12.10 to manifest it. I'm surprised that I haven't seen more reports of it. It also seems odd that some are reporting that the work arounds worked and others are not reporting the problem at all. I agree with another poster that this bug should be marked critical.

It's great that /etc/hosts is still consulted by ordinary lookups originating from the Ubuntu system, but the hardcoded removal of /etc/hosts use from dnsmasq config causes other problems, for example if you want this system to provide DNS services for other machines, for example even VMs running in VirtualBox, etc. on the same host.

AFAIK /etc/hosts is in not directly linked to dnsmasq and it doesn't matter whether DNS lookups are done externally or not. The standalone dnsmasq (i.e., the dnsmasq that runs when the dnsmasq package is installed) does consult /etc/hosts when resolving names. This feature can be disabled.

[Desktop-packages] [Bug 993298] Re: Please make NetworkManager-controlled dnsmasq respect /etc/hosts
Contributors have claimed here (bug #993298) above that /etc/hosts is no longer respected, but that is not the case. As always, with hosts: files [...] in /etc/nsswitch.conf, the libc resolver consults /etc/hosts first. Yes, NM runs dnsmasq with the no-hosts option. Consequently a DNS lookup on 127.0.0.1 does not respect /etc/hosts. But prior to Ubuntu 12.04, NM didn't start a local nameserver at all; no DNS lookups were done externally and /etc/hosts wasn't respected then either. The contributors who say that /etc/hosts is no longer consulted must (I conclude) have been running the standalone server version of dnsmasq before. That dnsmasq respects /etc/hosts and listens at 127.0.0.1 by default. Now, because of bug #959037 it is not possible in Ubuntu 12.04 to run standalone dnsmasq alongside nm-dnsmasq. But it *is* possible to run standalone dnsmasq if nm-dnsmasq is disabled (by commenting out dns=dnsmasq in /etc/NetworkManager/NetworkManager.conf and restarting network-manager) and that should restore the old situation. Assuming that the underlying wish is that standalone dnsmasq can be run without the need to comment out dns=dnsmasq, I propose to merge this report with #959037 which discusses ways of realizing this.

To my knowledge there's no other operating system distribution (including Mac + Windows) that does so. Of course you are free to configure default Ubuntu as you like. But it would be great to respect published upgrade policy. What happened is that the upgrade to 12.04 silently changed the configuration in a way that broke all working /etc/hosts configurations.
