FYI this will not effect DHCP as the hostname change is only used for mDNS and is not used as the system hostname and thus would affect DHCP etc
The cause of this is knwon and hopefully a fix will get done for it soon.. basically its when IP addresses are added then removed too fast. Can also happen with IPv6 because if a global address comes up the link local address is dropped. The code doesn't then handle teh previous announcement coming back into the avahi process and thiunks its a conflict. It's basically a race condition. Correct upstream issue is https://github.com/lathiat/avahi/issues/117 ** Bug watch added: github.com/lathiat/avahi/issues #117 https://github.com/lathiat/avahi/issues/117 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to avahi in Ubuntu. https://bugs.launchpad.net/bugs/831022 Title: avahi daemon erroneously assumes host name conflicts (and causes more trouble then) Status in Avahi: New Status in avahi package in Ubuntu: Triaged Bug description: Hi, i am running the server edition of Ubuntu LTS on a HP Proliant server. That avahi daemon is driving me crazy. The server is named Server1 , retrieves it's IP address pseudostatically from a DHCP server, and announces several of its services through avahi (e.g. offering print services to iPads, that's why Avahi is needed). every now and then (not always) avahi daemon claims to have detected a name collision at boot time. It then logs Aug 22 13:09:40 Server1 avahi-daemon[1520]: Host name conflict, retrying with <Server1-2> and uses Server1-2 as it's name, causing even the DHCP-Server to apply with a different host name, thus causing a new IP address to be assigned. This avahi daemon is breaking my network structure and does not even tell in the logs, where the conflict came from or what made the daemon believe that there was a conflict.
