Public bug reported: On 16.04 and 18.04 hosts on my LAN I've been suffering intermittent loss of mDNS resolution after devices have been suspended and resumed.
Today I decided to investigate and noticed that on resume the hostname being advertised is changed. E.g. hephaestion.local == Cold Boot hephaestion-1.local == 1st suspend/resume hephaestion-2.local == 2nd suspend/resume ... etc. It can be reset by restarting the service: systemctl restart avahi-daemon ** Affects: avahi (Ubuntu) Importance: Undecided Status: New ** Summary changed: - Suspend/Resume cycle changes advertised hostname + Suspend/Resume cycle changes advertised hostname (loss of name resolution) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763650 Title: Suspend/Resume cycle changes advertised hostname (loss of name resolution) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1763650/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
