How to control startup options of dnsmasq?

  • 772

I'm on Ubuntu 16.04 Xenial and Network Manager started dnsmasq for me with these options:

~/ ps awux|grep dnsmasq
nobody    2649  0.0  0.0  54488  3588 ?        S    Mai23   0:00 /usr/sbin/dnsmasq --no-resolv --keep-in-foreground --no-hosts --bind-interfaces --pid-file=/var/run/NetworkManager/dnsmasq.pid --listen-address=127.0.1.1 --cache-size=0 --proxy-dnssec --enable-dbus=org.freedesktop.NetworkManager.dnsmasq --conf-dir=/etc/NetworkManager/dnsmasq.d

I'd like dnsmasq to read/use the /etc/hosts file as well, which it currently doesn't seem to, because of the option --no-hosts.

How do I change the startup options, that Network Manager uses to invoke dnsmasq?

  1. All dnsmasq configuration files you add into /etc/NetworkManager/dnsmasq.d/ are passed to dnsmasq. Just check it with the command: 

    ps -ef | grep -P "dnsmasq\s"

    I get this kind of result (notice the --conf-dir parameter):

    nobody    6105  5868  0 20:20 ?        00:00:00 /usr/sbin/dnsmasq --no-resolv --keep-in-foreground --no-hosts --bind-interfaces --pid-file=/run/NetworkManager/dnsmasq.pid --listen-address=127.0.1.1 --cache-size=0 --clear-on-reload --conf-file=/dev/null --proxy-dnssec --enable-dbus=org.freedesktop.NetworkManager.dnsmasq --conf-dir=/etc/NetworkManager/dnsmasq.d

    So you could just create a file e.g. /etc/NetworkManager/dnsmasq.d/my-hosts containing the declaration:

    addn-hosts=/etc/hosts

    in order to use /etc/hosts (see doc). But because dnsmasq starts also with --no-hosts this might determine dnsmasq to still ignore /etc/hosts so you could just create a hard link to it e.g.:

    sudo cp -al /etc/hosts /etc/my-hosts

    then change the declaration to:

    addn-hosts=/etc/my-hosts
