Change the hostname of a WLAN Pi
By default, the hostname of your WLAN Pi is : wlanpi
If you'd like to change this to a more meaningful hostname, then you will need to SSH to your WLAN Pi and update the /etc/hostname and /etc/hosts files, followed by a reboot of the WLAN Pi:
Edit the /etc/hostname file using the command:
sudo nano /etc/hostname
There is a single line that says 'wlanpi'. Change this to your required hostname. Then hit Ctrl-X and "y" to save your changes.
Alternatively, you may also use the following CLI command to achieve the same result:
sudo hostnamectl set-hostname <name>
Whichever method is used to update the hostname file, next edit the /etc/hosts file:
sudo nano /etc/hosts
Change each instance of 'wlanpi' to the new hostname (there are usually two instances). Then hit Ctrl-X and "y" to save your changes.
Finally, reboot your WLAN Pi:
sudo reboot
