I am encountering the same behavior . avahi is struggling with dhclient and my network interface is being reconfigured every few minutes. This is very annoying. Not only is the network completely down while DHCP renegotiation takes place, but the interface often gets a new address. Thus all ssh connections freeze and must be recreated.

Above, we see "avahi-daemon[5296]: Withdrawing address record for 169.236.152.55 on eth0" - meaning avahi-daemon is trashing my DHCP- assigned address. Then dhclient gets the address back. Then avahi-daemon "withdraws" it again. Back and forth. At another point, avahi-daemon tried to assign address "169.254.5.160" to eth0 - I have no idea where it got that. It has nothing to do with our network. -- Constantly reconfiguring network interface https://bugs.launchpad.net/bugs/122659 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
