I also wonder if this is some sort of infection... some strange process hijacking DNS.

Status in “network-manager” package in Ubuntu: New Bug description: There is a local network, with two DNS servers, and a DHCP server. They are both correctly configured and entirely functional, with correct zoning (bind9) for split-horizon DNS. This has been a working configuration for years. DHCP is configured so that clients use these internal DNS servers. There is no configuration in /etc/network/interfaces, so this is entirely run by network-manager. When the wireless configuration comes up, rather than pointing at the LAN dns servers, it points at 127.0.0.1. I can identify no process providing the caching servics, ps -ax | grep ns, name, bind, all come up empty. Whatever is doing name resolution, it is not using the LAN's DNS servers, because none of the internal zone entries are available. While public name resolution works, ssh to other systems on the LAN fail because the internal zone host names are never found. If I manually place the local dns servers in /etc/resolv.conf, everything works fine for a few minutes, when something overwrites it back to 127.0.0.1 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: network-manager 0.9.3.995+git201203152001.04b2a74-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-18.29-generic 3.2.9 Uname: Linux 3.2.0-18-generic x86_64 ApportVersion: 1.95-0ubuntu1 Architecture: amd64 Date: Sat Mar 24 09:55:26 2012 IfupdownConfig: auto lo iface lo inet loopback InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Beta amd64 (20120301) NetworkManager.state: [main] NetworkingEnabled=true WirelessEnabled=true WWANEnabled=true WimaxEnabled=true ProcEnviron: LANGUAGE=en_CA:en TERM=xterm PATH=(custom, user) LANG=en_CA.UTF-8 SHELL=/bin/bash SourcePackage: network-manager UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/963943/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
