This is based on the following: https://github.com/troyxmccall/dotfiles/blob/ae78ab87c861efe27aee7ede47cd0e61dac8fe22/.functions#L419-L442

I changed it to be a script, and fixed some issues related to handling of versions.

Start up a container (whichever Linux flavour takes your fancy):

docker run -it ubuntu /bin/bash
docker run -it centos /bin/bash

• top: check what CPU and Memory running processes are utilising
• ps: see what processes are running
• strace: monitor interactions between processes

The example below creates a TCP server listening on a stream (i.e. SOCK_STREAM) socket. A similar approach can be followed to create a UDP server on a datagram (i.e. SOCK_DGRAM) socket. See man systemd.socket for details.

An example server

Create an simple echo server at /opt/foo/serve.py.
