Run iperf3 server

By far, we have only used the client component of iperf3 by specifying

./iperf3 -c [some server]

You can also run an iperf3 server yourself and connect to it! (or let others connect to it)

Follow instructions https://iperf.fr/iperf-servers.php#host-iperf3 for details on how to set up a server on Debian/Ubuntu.

Note, you don't have to follow the complete steps above - for instance, running the following would simply work

./iperf3 -s

Although you might want to specify a different port with -p or run it as a daemon with -D. Use -h for a complete list of options.
