[Touch-packages] [Bug 1638836] Re: resolv.conf for resolved stub server should have a comment how to see the actual servers
Martin, Please note, that in my setup, the network is lost immediately after rebooting with the new network-manager (1.4.2-2ubuntu4). Then, downgrading back to version 1.4.2.-2ubuntu3, and rebooting, I get network back. In both of these versions, the network-manager creates the same kind of file /etc/resol.vconf. I only use a cable network. I do not have the package resolvconf installed, as no other package depends on it (isc-dhcp-client merely suggests it). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to resolvconf in Ubuntu. https://bugs.launchpad.net/bugs/1638836 Title: resolv.conf for resolved stub server should have a comment how to see the actual servers Status in network-manager package in Ubuntu: Fix Released Status in resolvconf package in Ubuntu: Fix Released Bug description: resolv.conf currently just has nameserver 127.0.0.53 with resolved (its local stub resolver).

[Touch-packages] [Bug 1638836] Re: resolv.conf for resolved stub server should have a comment how to see the actual servers
This bug was fixed in the package network-manager - 1.4.2-2ubuntu4 --- network-manager (1.4.2-2ubuntu4) zesty; urgency=medium [ Martin Pitt ] * Add resolved DNS plugin (backported from upstream master). * Disable resolvconf support. This is broken with DNS plugins other than "dnsmasq" -- it still writes 127.0.1.1 into resolvconf as a nameserver, but this does not exist any more and will also shadow resolved's stub server on 127.0.0.53. This ought to be fixed more properly in the future. [ Steve Langasek ] * Re-drop dnsmasq in zesty, in favor of systemd-resolved. This unifies DNS lookups between Ubuntu desktop and server. But don't Recommend libnss-resolve, because the local resolver + libnss_dns.so should suffice for all uses and the resolved nss module is unnecessary added complexity. We need to specify "dns=systemd-resolved" as for the time being our /etc/resolv.conf points to resolvconf's generated file instead of systemd-resolved's, so the auto-detection does not work. Do that in a separate conf.d file in /usr to avoid unnecessary conffile prompts in the future.

https://blueprints.launchpad.net/ubuntu/+spec/foundations-y-local- resolver has the two outstanding issues to switch NM over to resolved too. These are unblocked now: the new resolved DNS plugin is in upstream master since around September, and NM 1.4 landed in zesty-proposed yesterday. Let's land that first, then backport the DNS plugin and switch it over, then we'll consistently use resolved everywhere and that comment will be much easier to write.

[Touch-packages] [Bug 1638836] Re: resolv.conf for resolved stub server should have a comment how to see the actual servers
Right, I think the file should only document the Ubuntu-specific things such as the facts that by default resolvconf and the systemd resolver are used, NetworkManager is used by default on Desktop and ifup on Server, and so on. There have been hundreds of questions about these basic things on AskUbuntu and the forums over the years. I have often referred people to Stephane Graber's blog post (https://www.stgraber.org/2012/02/24/dns-in-ubuntu-12-04/) for background info but this is as of 16.11 no longer adequate. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to resolvconf in Ubuntu. https://bugs.launchpad.net/bugs/1638836 Title: resolv.conf for resolved stub server should have a comment how to see the actual servers Status in resolvconf package in Ubuntu: In Progress Bug description: resolv.conf currently just has nameserver 127.0.0.53 with resolved (its local stub resolver).

[Touch-packages] [Bug 1638836] Re: resolv.conf for resolved stub server should have a comment how to see the actual servers
Right, the comment would need to be conditional. My original naïve approach was to add the comment together with the nameserver, such as printf "# Run systemd-resolve --status blabla\nnameserver 127.0.0.53\n" | /sbin/resolvconf -a systemd-resolved so that the comment would only be there when appropriate and would also be at the appropriate line. manpage> Not sure if that really helps -- this would also have to contain a lot of "if"s, like "if you have resolved/unbound/NM's dnsmasq/etc." and document all of these cases, which is both confusing and also prone to get out of sync with their respective upstreams.

[Touch-packages] [Bug 1638836] Re: resolv.conf for resolved stub server should have a comment how to see the actual servers
If such a comment were to be added then in order not to mislead it would have to take into account the configurability of various components. So you'd have to say something like: «If the line "nameserver 127.0.0.53" is present then it probably refers to the systemd resolver listening on the loopback address. By default the systemd resolver is also configured to handle name queries via the Name Service Switch whose configuration file is nsswitch.conf. The name servers to which the systemd resolver forwards queries can be discovered by running "systemd-resolve --status".» What would be far better, though, is to include a text file or manpage explaining how name service currently works in Ubuntu. (Actually we should have done this long ago.) The file could include the previous paragraph but would also talk about resolvconf and NetworkManager and its plugins. The name of this file could then be mentioned in the header that resolvconf writes into resolv.conf. /etc/resolvconf/resolv.conf.d/head would then be: # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # For more info see /usr/share/doc/resolvconf/name-service-in-Ubuntu.txt # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to resolvconf in Ubuntu. https://bugs.launchpad.net/bugs/1638836 Title: resolv.conf for resolved stub server should have a comment how to see the actual servers Status in resolvconf package in Ubuntu: In Progress Bug description: resolv.conf currently just has nameserver 127.0.0.53 with resolved (its local stub resolver).
