Measuring network bandwidth using iperf3
Install on both the client and the server:
sudo apt install iperf3
Run on the server:
iperf3 --server --port <port>
For example:
iperf3 --server --port 1234
Run on the client:
iperf3 --client <host> --port <port>
For example:
iperf3 --client 192.168.1.233 --port 1234
Example output on the client side:
Connecting to host 192.168.1.2, port 1234
[ 5] local 192.168.1.3 port 56760 connected to 192.168.1.2 port 1234
