Ubuntu server 18.04 LTS is a rather popular linux OS for servers.

Whether it’s the “Iranian Cyber Army”, those darn “Chinese Hackers”, or just your average script kiddie, everyone is aware that there bad people out there who want to mess with your glorious internet surfing experience.

No. And contrary to popular belief, we are generally good-looking. It’s all part of Nerd 2.0.
But, I digress.
