Device name required for the "allowed devices" white list of an Android mobile hotspot?

  • 772

I want to my laptop running Ubuntu to the white list of an Android WiFi hotspot. Doing hostnamectl returns, amongst other information, a Static hostname, an Icon name, a Machine ID, and a Boot ID. Which of these is the right one?

I got the MAC address of the wlan0 interface by doing ip addr in the terminal and added it, together with the Static hostname, to the white list, but the connection fails. Signal strength is very good and the WPA2 password is correct.

PS.: On a Windows 10 machine, you get the corresponding name by doing hostname in the command line or looking it up in Settings > System > About under "Device name".

    The content of /etc/hostname is the hostname of the system.

    Easiest to get would be with cat /etc/hostname or just calling the program hostname.

    hostnamectl gives a lot of additional information (as you have seen) which can be confusing; it's better to use /etc/hostname directly.
