avahi-set-host-name

Set mDNS hostname

$ avahi-set-host-name [newhost]

avahi-set-host-name hostname

avahi-set-host-name changes the mDNS hostname advertised by the Avahi daemon. This allows you to change how your system appears on the local network without modifying system hostname files.
The change is immediate and affects service discovery on the local network.

This command takes a single argument - the new hostname to advertise.

The hostname will be advertised as hostname.local on the network. Other devices can reach your system using this name.

Requires avahi-daemon running. Does not change the system hostname (see hostname command). Changes may not persist after daemon restart. Hostname must be valid DNS name.

avahi-set-host-name is part of the Avahi suite, a free Zeroconf/Bonjour implementation started by Lennart Poettering around 2005.
