thank you for your bug report.

[Touch-packages] [Bug 1718890] Re: name resolution stops working
To make clear the bearing of this: systemd-resolved stops working on EVERY machine here after 5 minutes. the DNS server has not been down since April A Macintosh running macOS High Sierra installed for comparison can resolve and connect to internal resources in every case where Ubuntu looses connection. And a last one: internally, my domain uses .internal as domain name. I want to keep this separate from my official domains. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1718890 Title: name resolution stops working Status in systemd package in Ubuntu: New Bug description: System: Ubuntu 17.10 beta DNS server hosts an internal and an external domain (the internal is used for internal purposes).

[Touch-packages] [Bug 1718890] Re: name resolution stops working
Just found this article https://github.com/systemd/systemd/issues/5755 Following the argument, systemd-resolved resolves DNS names on the assumption that all configured DNS servers are equal. diego-treitos and others argue that in small/medium sized companies, DNS configuration will have an external DNS server configured and conveyed via DHCP. This is the case here as well. This has not posed a problem before systemd-resolved was adopted. But when a resolver insists on treating the fallback equally and keeping the connection till the next fallback, internal DNS resolution is not possible any more. It breaks known and established configurations. I have to accept that RFCs actually lend to the interpretation of poettering. In this case (as he is reluctant to adapt his softwares behaviour to previously known standards) there need to be a quick way to eliminate systemd-resolver from the system. I for one need the old behaviour with a primary DNS (internal, it resolved private addresses as well) and a secondary DNS (external, which only resolved external / official addresses) as a fallback. ** Bug watch added: github.com/systemd/systemd/issues #5755 https://github.com/systemd/systemd/issues/5755 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1718890 Title: name resolution stops working Status in systemd package in Ubuntu: New Bug description: System: Ubuntu 17.10 beta DNS server hosts an internal and an external domain (the internal is used for internal purposes).
