Mine is (on 13.04):

[root at localhost:~]# ps ax o cmd | grep dns | grep -v grep
/usr/sbin/dnsmasq --no-resolv --keep-in-foreground --no-hosts
--bind-interfaces
--pid-file=/var/run/sendsigs.omit.d/network-manager.dnsmasq.pid
--listen-address=127.0.1.1 --conf-file=/var/run/nm-dns-dnsmasq.conf
--cache-size=0 --proxy-dnssec
--enable-dbus=org.freedesktop.NetworkManager.dnsmasq
--conf-dir=/etc/NetworkManager/dnsmasq.d
[root at localhost:~]#

My system's output has a different "--listen-address=" option and has
"--enable-dbus=" and "--conf-dir=" options. IIRC, the first two are
due to changes made between 12.04 and 12.10 or 12.10 and 13.04. The
last doesn't seem to matter because I haven't been able in the past to
pass different options to dnsmasq through it.

Is dnsmasq being kicked off by NM? (It must since you have
"/nm-dns-dnsmasq.conf" but just in case...)

[root at localhost:~]# ps ax --sort=pid o pid,ppid,cmd | grep Net | grep -v grep
  761     1 NetworkManager
 1596   761 /usr/sbin/dnsmasq --no-resolv --keep-in-foreground
--no-hosts --bind-interfaces
--pid-file=/var/run/sendsigs.omit.d/network-manager.dnsmasq.pid
--listen-address=127.0.1.1 --conf-file=/var/run/nm-dns-dnsmasq.conf
--cache-size=0 --proxy-dnssec
--enable-dbus=org.freedesktop.NetworkManager.dnsmasq
--conf-dir=/etc/NetworkManager/dnsmasq.d
[root at localhost:~]#

So your DNS server is 192.168.1.254; your router, I assume.

:(


I don't see why your setup isn't working. Why don't you edit
"/etc/resolvconf/resolv.conf.d/head" or "/etc/dhcp/dhclient.conf" to
get the OpenDNS nameservers into "/etc/resolv.conf"?

(Is "/etc/resolv.conf" a symlink to a file in "/run"/"/var/run"?)
