Let's get <SSH> access, instal a package, and run a server.

As of December 2023 on a `t2.micro` instance, the only one part of free tier at the time with advertised 1 vCPU, 1 GiB RAM, 8 GiB disk for the first 12 months, on <Ubuntu 22.04>:
``
$ free -h
               total        used        free      shared  buff/cache   available

``

To install software:
``
sudo apt update
sudo apt install cowsay
cowsay asdf
``

Once HTTP inbound traffic is enabled on security rules for port 80, you can:
``
while true; do printf "HTTP/1.1 200 OK\r\n\r\n`date`: hello from AWS" | sudo nc -Nl 80; done
``
and then you are able to `curl` from your local computer and get the response.
