Identify the pi by hostname

[gproduct]

Hello!

I'm working on a project for which I need to know the ip of a pi with a hostname 'test'.

How do I achieve this?

Should I go the long route and ping every device on the network, but how do I know if the hostname is 'test'?

Thanks!

Current versions of Raspbian broadcast to the LAN. You can connect to one by connecting to "<hostname>.local" providing the source system has the feature enabled. In your case, "test.local".

Hi!
If the pi named test is running stock Raspbian, then the avahi daemon is running on it.
So from another machine on the network you can ping the pi with this command

Code: Select all

ping test.local

Note that this machine must also run avahi/mDNS/Bonjour. This will be the case with a Mac or a recent GNU/Linux but not with Windows (however it seems possible to add this service to Windows as well)
