• Deny root login to the server
• Setup Uncomplicated Firewall
• Create Swap file based on machine's installed memory

• Install Network Time Protocol

Customized by Matchaism:

• Change SSH port num.
• Put secret scripts in private dir.

Setup prompts

When the setup script is run, you will be prompted to enter the username of the new user account.

Following that, you will then be prompted to add a public ssh key (which should be from your local machine) for the new account. To generate an ssh key from your local machine:

ssh-keygen -f ~/.ssh/<keyfile_name>
