  1. Very interesting article on how to enable single use password logon for Ubuntu. Requires a thing called opie and a few config file changes. Seems very useful...
  2. Useful forum post that explains the `top -b` option, making top output text suitable for piping / writing to file, like `top -bn1 | mail`...
  3. Very simple guide to using ufw to create firewall rules. `ufw allow ssh/tcp && ufw allow http/tcp && ufw allow https/tcp && ufw enable && ufw status` done. :-)
