[Bug 956655] Re: libvirt dnsmasq causes runaway chain reaction
mbp@joy% cat /var/run/nm-dns-dnsmasq.conf server=10.0.3.1 server=192.168.178.1 server=10.0.3.1 server=192.168.178.1 I think this is an interaction between a few things that are themselves reasonable: - network-manager depends on dnsmasq, and makes it the default nameserver in /etc/resolv.conf - lxc also sets up a dnsmasq for the guest, forwarding to the host - lxc(?) inserts into dhclient.conf ./dhcp/dhclient.conf:prepend domain-name-servers 10.0.3.1; - so the host ends up querying the guest, which loops back to the host This might be just something in my own set up, and obviously I can avoid it here, but it does look like it could bite others. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/956655 Title: libvirt dnsmasq causes runaway chain reaction To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/956655/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

removing lxc has avoided the problem. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/956655 Title: libvirt dnsmasq causes runaway chain reaction To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/956655/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

ok, after discussion on irc, apparently it's launchpad's setuplxc that's inserting the conf:prepend domain-name-servers 10.0.3.1; line. I'm not sure if this problem could still be hit without it. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/956655 Title: libvirt dnsmasq causes runaway chain reaction To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/956655/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 956655] Re: libvirt dnsmasq causes runaway chain reaction
It's arguably a dnsmasq/lxc problem that this can occur, but I think the most relevant problem is Launchpad's setuplxc changing my dhclient configuration. I guess this was done so that the host could see launchpad.dev or whatever. But: - changing basic networking of the host without warning people seems rude to say the least - it fucks up my whole network ** Package changed: dnsmasq (Ubuntu) = launchpad -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/956655 Title: libvirt dnsmasq causes runaway chain reaction To manage notifications about this bug go to: https://bugs.launchpad.net/launchpad/+bug/956655/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
