Kill busy session via Raritan CLI

On the GUI it was simple to find to kill a busy session on a console port, but I couldn’t find a way to force logoff a busy session in CLI

when you logged in and you find yourself a busy console and you don’t want to login all the way to the GUI and clear it, this is the CLI command’s for this;

admin > 20
Sorry, port is busy!
admin > maintenance 
admin > Maintenance > logoff port 20
Force log off successful.

admin > Maintenance > top
admin > 20
You are now master for the port.
 Escape Sequence is: Control-]

And it’s all yours again \o/

This was on a Dominion SX2; model DSX-32.

Pi-Hole and PowerDNS

Since a while I’m using Pi-hole in my home to filter all kinds of domain names. This in combination with a PowerDNS resolver makes gives me more privacy. At least not monitored by the ‘free’ DNS resolvers out there…

PowerDNS is running on my Synology NAS in a docker container. Pi-Hole is still running on a Raspberry Pi 3 Model B+ since I wanted to test first and did not want to touch my working PowerDNS setup. but it already running fine for a while and I need to still move form the Pi to a docker as well. I will update this post when I moved everything with the detailed docker information as well.

Currently Pi-Hole v5 is just out, so I want to wait for a short moment when the fist fixed are done and the move to docker as well.

Cool thing with Pi-Hole is that you can use your one blocklists. Some I took form fireblog.net.
