Control user access to SSH
Got a shiny new Linux box on your network but don’t want all your users connecting to it via SSH? Control access by editing the SSH configuration file and using the AllowUsers directive like so:
AllowUsers joeuser
To add multiple entries, either separate users with a space, or write an entirely new line:
AllowUsers joeuser philwiffen
AllowUsers joeuser
AllowUsers philwiffen
