CentOS Linux Avahi Error: avahi-daemon[2699]: Invalid query packet
While troubleshooting another problem this evening I noticed a bunch of avahi-daemon errors in the messages log on a CentOS Linux development server. The error hasn’t caused any issues that I am aware of and may be a simple case of a new warning message or another server on the network sending rogue DNS packets to the CentOS server in question. Below is information displaying the error in the messages log and what steps I took to resolve the problem.
