Host name conflict with avahi daemon on Ubuntu 14.04 LTS

  • 772

I have two VMs running Ubunut 14.04 on Virtualbox. They are connected via VIP. Syslog on node1 shows recuring error messages from Avahi and I can't find the problem nor the solution.

tail /var/log/syslog

How could I fix this problem? Config looks OK to me.

  1. If your DNS server that this server uses has a .local domain then avahi will fail to work. See http://avahi.org/wiki/AvahiAndUnicastDotLocal for more info on this.
