mtr should already be on the server..just type:
mtr <your home IP address>
sudo apt install iperf
sudo apt install iperf3
iperf -s or
You'll then need an iperf or iperf3 client on your home side.
iperf -c server will connect to your server and check transfers from home to server.
iperf -c server -R will check seedbox to home.
I run mine as a service on my seedbox so the iperf servers are always running.
