I have both wired and wireless connections to the same LAN. If I disable wireless then there is only one instance of the address left in nm-dns-dnsmasq.conf.
If I instead disconnect the Ethernet cable then there is only one instance of the address left in nm-dns-dnsmasq.conf. So it seems that the two lines correspond to two interfaces, eth0 and wlan0, by which the (same) nameserver address can be reached. Whatever the cause of the duplication might be, though, I'd think that NM should de-duplicate the list of addresses it gives to dnsmasq. ** Summary changed: - NM writes duplicate lines in /var/run/nm-dns-dnsmasq.conf + If it obtains the same nameserver address for multiple interfaces, NM fails to de-duplicate the list of addresses it gives to dnsmasq via nm-dns-dnsmasq.conf and just includes the same address multiple times -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1015493 Title: If it obtains the same nameserver address for multiple interfaces, NM fails to de-duplicate the list of addresses it gives to dnsmasq via nm-dns-dnsmasq.conf and just includes the same address multiple times Status in “network-manager” package in Ubuntu: New Bug description: From /var/log/syslog: Jun 20 10:03:25 tenerife dhclient: DHCPREQUEST of 192.168.2.103 on eth0 to 255.255.255.255 port 67 Jun 20 10:03:25 tenerife dhclient: DHCPOFFER of 192.168.2.103 from 192.168.2.254 Jun 20 10:03:25 tenerife dhclient: DHCPACK of 192.168.2.103 from 192.168.2.254 Jun 20 10:03:25 tenerife dhclient: bound to 192.168.2.103 -- renewal in 276336 seconds.
