[Bug 959037] Re: Don't start local resolver if a DNS server is installed
Listening on lo is fine; and blocking other DNS servers from being started isn't. I think we're in violent agreement there. The problem is how to fix this. I'm not saying dnsmasq should be crippled, but that it should special- case lo and not just listen on 0.0.0.0; because that binds to any further use of port 53, which might not work with any further processes that might want to legitimately listen on port 53. That's pretty much how the solution is shaping to be: when listening on all interfaces, listen on each interfaces separately; binding to the IP address attached to the interface (or via any other mean). We should then be able to have dnnsmasq listen on 127.0.1.1:53 to satisfy the need for a local resolver. -- 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/959037 Title: Don't start local resolver if a DNS server is installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/959037/+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 959037] Re: Don't start local resolver if a DNS server is installed
@jdthood: the "Standalone dnsmasq is not compatible out of the box with NM+dnsmasq" title hints that the problem is caused by the dnsmasq package, i.e. that it should be crippled and not listen on "lo" by default in order to coexist with the local resolver implementation. I don't think this is the case, I don't think the dnsmasq package does anything wrong; I just cross-linked the bug report in case other people hit the problem and try to find it in the dnsmasq bug page. The problem should be fixed from the network-manager side. Otherwise, similar bug reports should be filed against all other DNS server packages, not just dnsmasq. But I really think that people do want their DNS servers to listen on "lo" by default. They wouldn't want to break that just to help the local resolver implementation. -- 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/959037 Title: Don't start local resolver if a DNS server is installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/959037/+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 959037] Re: Don't start local resolver if a DNS server is installed
Just as a short reminder, there are more DNS-resolver/server available as packages out there than just bind and dnsmasq, i.e. djbdns and it's derivates. Until I removed the annoying dns=dnsmasq line in /e/N/Nconf, NM disconnected the WLAN after a couple of minutes, throwing an error about dnsmasq not able to bind to 127.0.0.1. I'm puzzled about the default inclusion of dnsmasq as a local resolver for standard users. If a connection is to be shared, it might be useful to bind dnsmasq to the shared iface to provide DHCP and DNS, like it's done with libvirt-bin. -- 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/959037 Title: Don't start local resolver if a DNS server is installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/959037/+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

> The configuration itself shipped by default should be patched If you mean something like: except-interface=lo bind-interfaces ...I just tested them and they do allow both dnsmasq instances to run. But of course those settings won't be acceptable to most dnsmasq users, as listening on "lo" is usually desired too (local DNS cache; DHCP/TFTP for VMs etc). So I don't think that crippling the default dnsmasq functionality is a good way to solve this problem. DNS clients shouldn't hook port 53; it's reserved for DNS servers. -- 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/959037 Title: Don't start local resolver if a DNS server is installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/959037/+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

That wouldn't be the right process though.

[Bug 959037] Re: Don't start local resolver if a DNS server is installed
Since this won't be fixed for Precise from the network-manager side, the dnsmasq package now is broken by default in desktop installations. So I've added the dnsmasq package in the "Affects:" list, to make it easier for people to locate the cause of the problem so that fewer duplicate bug reports are filed (it's an LTS release, I suppose many people will be bitten by it in the next 5 years). Also, even though it's not the correct place to solve the problem, the dnsmasq.postinst could be temporarily modified to disable the local resolver. I can propose a patch for it if the maintainer is interested. -- 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/959037 Title: Don't start local resolver if a DNS server is installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/959037/+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
