Is this behavior related to the bug? I have running router on 192.168.31.1 Then, I run a test setup of bionic on virtual box as a squid proxy. Everything fine, almost.
I found every local network names are failed to be resolved by the new bionic installation, but outside local network names are resolved. It is as if the system resolve the domain name to another dns server beyond configuration. root@rld-proxy:/etc/NetworkManager/dispatcher.d# systemd-resolve --status Global DNSSEC NTA: 10.in-addr.arpa 16.172.in-addr.arpa 168.192.in-addr.arpa 17.172.in-addr.arpa 18.172.in-addr.arpa 19.172.in-addr.arpa 20.172.in-addr.arpa 21.172.in-addr.arpa 22.172.in-addr.arpa 23.172.in-addr.arpa 24.172.in-addr.arpa 25.172.in-addr.arpa 26.172.in-addr.arpa 27.172.in-addr.arpa 28.172.in-addr.arpa 29.172.in-addr.arpa 30.172.in-addr.arpa 31.172.in-addr.arpa corp d.f.ip6.arpa home internal intranet lan local private test Link 2 (enp0s3) Current Scopes: DNS LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no DNS Servers: 192.168.31.1 root@rld-proxy:/etc/NetworkManager/dispatcher.d# nslookup dm97-pandorabox Server: 127.0.0.53 Address: 127.0.0.53#53 ** server can't find dm97-pandorabox: SERVFAIL root@rld-proxy:/etc/NetworkManager/dispatcher.d# nslookup dm97-pandorabox 192.168.31.1 Server: 192.168.31.1 Address: 192.168.31.1#53 Name: dm97-pandorabox Address: 192.168.31.1 Name: dm97-pandorabox Address: fd76:bf99:23d7::1 Any thoughts? If any work around produce another bugs, I guess it is safe for me to pending upgrade to bionic. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1624320 Title: systemd-resolved appends 127.0.0.53 to resolv.conf alongside existing entries To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1624320/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
