7. APPENDIX

8.1 Get the IP address

There are many ways to know the IP address, and two of them are listed as follows.

Checking via the router

If you have permission to log in the router(such as a home network), you can check the addresses assigned to Raspberry

Pi on the admin interface of router.

The default hostname of the Raspberry Pi OS is raspberrypi, and you need to ﬁnd it. (If you are using ArchLinuxARM

system, please ﬁnd alarmpi.)

Network Segment Scanning

You can also use network scanning to look up the IP address of Raspberry Pi. You can apply the software, Advanced

IP scanner and so on.

Scan the IP range set, and the name of all connected devices will be displayed. Similarly, the default hostname of the

Raspberry Pi OS is raspberrypi, if you haven’t modiﬁed it.

8.2 Install OpenSSH via Powershell

When you use ssh <username>@<hostname>.local (or ssh <username>@<IP address>) to connect to your

Raspberry Pi, but the following error message appears.

ssh: The term 'ssh' is not recognized as the name of a cmdlet, function,␣

˓→script file, or operable program. Check the

spelling of the name, or if a path was included, verify that the path is␣

˓→correct and try again.

It means your computer system is too old and does not have OpenSSH pre-installed, you need to follow the tutorial

below to install it manually.

1. Type powershell in the search box of your Windows desktop, right click on the Windows PowerShell, and

select Run as administrator from the menu that appears.
