825gen2 Development

SSH

SSH (Secure SHell) is very useful for development on the 825gen2.

From a PC on the same network as the 825 you may use a Command Prompt or PowerShell window and type: "ssh admin@<ip_address_of_825>" such as:

PS C:\> ssh admin@10.1.2.230
admin@10.1.2.230's password:
card825gen2:~$

You will then have access to the terminal to run commands on the 825. For example "free -h" shows information about the 825 RAM memory usage.

card825gen2:~$ free -h
               total        used        free      shared  buff/cache   available
Mem:           3.8Gi       441Mi       3.2Gi        19Mi       202Mi       3.2Gi
Swap:             0B          0B          0B
