You can access the command line of a Raspberry Pi remotely from another computer or device on the same network using SSH.
##1. Set up your client SSH is built into Linux distributions and Mac OS. For Windows and mobile devices, third-party SSH clients are available. See the following guides for using SSH depending on the OS used by the computer or device you are connecting from:
Note that you only have access to the command line, not the full desktop environment. For the full remote desktop, see VNC.
##2. Set up your local network and WiFi
Make sure your Raspberry Pi is properly set up and connected. If you're using WiFi, this is done using the wpa_supplicant.conf config file.
Otherwise, plug your Raspberry Pi directly into the router.
##3. Enable SSH As of the November 2016 release, Raspbian has the SSH server disabled by default. You will have to enable it manually. This is done using raspi-config:
Enter sudo raspi-config in the terminal, first select Interfacing options, then navigate to ssh, press Enter and select Enable or disable ssh server.
For headless setup, SSH can be enabled by placing a file named 'ssh', without any extension, onto the boot partition of the SD card.
