Okay, so now I verified that the nameserver was added to resolv.conf. Then I rechecked before disconnecting and noted that the extra resolv.conf entry had disappeared (without changes to network configuration in the meanwhile). nm-tool reported the correct nameserver address still, and it seemed to work through the local proxy (one presumes). So the generated resolv.conf entry seems both unnecessary and possibly transient, though as said, it has persisted beyond disconnecting the Bluetooth PAN at least two times.
Everything working even without the entry indicates that it probably shouldn't be generated at all. -- 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/1389798 Title: Using Bluetooth PAN leaves broken resolv.conf Status in “network-manager” package in Ubuntu: New Bug description: Having paired an Android phone, the network manager menu in Unity displays the "GT-I9300 Network" appropriately and I can tether over the phone's mobile broadband just fine. However, the PAN's nameserver setting is put directly into /etc/resolv.conf (instead of doing the dnsmasq thing) _and_ is left there, like so, even after disconnecting and connecting to a different (WiFi) network: # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 192.168.44.1 nameserver 127.0.1.1 (The 127.0.1.1 part isn't there before connecting to WiFi, it is added at that point, but the now-defunct BT PAN nameserver address persists.) This greatly interferes with DNS queries.
