 3) Check whether the `allow=` line already contains your current IP number (if yes, exit the script);

 On Windows, this script connects to your server via SSH using Plink (part of the [Putty](https://www.chiark.greenend.org.uk/~sgtatham/putty/) package).
 Therefore, it requires you to:
 1) Have Putty present on your machine;
-2) Customize the script, providing the path to the Plink executable (if not in `$PATH`);

The host public key honestly is not always necessary, once it is saved in the SSH cache. I've found this to be a requirement only under Windows, and probably only the first time the script is ran.)
