Lakka uses Avahi to publish its hostname on its local network. By default, a system running Lakka is accessible as lakka.local within your local network without explicitly knowing its IP address. (It is also accessible as simply lakka via Samba.)
ssh [email protected]
However, if you have multiple machines running Lakka, setting a unique hostname for each will avoid name collisions.
Using the command line interface:
echo "picard" > /storage/.cache/hostname
Upon rebooting, the system will be accessible as picard.local within your local network. (The Samba name will be simply picard.)
