SSH (Secure SHell) is a great way to access a remote or headless Raspberry Pi across a network. It does this via a text terminal (so you are back in the old days!) on your local Mac.
SSH is built into a Mac so there’s no software to install. To setup an SSH session, first launch a Terminal Window. This can be found under Launchpad – > Other:
On launching, you’ll be presented with a command line:
If you know the IP address of your Raspberry Pi, you can access it like this:
ssh <IP Address of Raspberry PI> -l <username on Rpi>
For example for an Rpi at IP address 192.168.1.180
ssh 192.168.1.180 -l pi (assuming you are still using the default user of ‘pi’)
When you first run it you’ll get a message about the “authenticity of the host”. Click ‘yes” to store the key.
Next put in the password (default raspberry).
Here is a typical sequence:
That’s it! You are logged in over an SSH link to the Rpi.
