What exactly is AVAHI?

  • 772

CentOS 5.2

My VPS host rebooted (checking with host support now) and I noticed the following in /var/log/messages

Aug 28 11:57:52 echo avahi-daemon[21633]: **Found user 'avahi' (UID 70) and group 'avahi' (GID 70).**
Aug 28 11:57:52 echo avahi-daemon[21633]: **Successfully dropped root privileges.**

Aug 28 11:57:52 echo avahi-daemon[21633]: WARNING: Failed to contact D-Bus daemon.
Aug 28 11:57:52 echo init: no more processes left in this runlevel

What exactly is avahi? Is this a standard message?

linux centos vps openvz avahi

  1. Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. More information here.

    As Iain said Avahi provides similar functionality to Bonjour or Rendezvous for Linux. On a server I really don't see a need for it... I've turned it off myself on servers I've setup.

    You can stop the service and then turn it off at boot using these two commands:

    service avahi-daemon stop 
chkconfig avahi-daemon off
