// To be able to SSH into one of the DigitalOcean servers from an external location, you will need to be added to the whitelist.

1) Log in to the DigitalOcean console
// The details for this are in PassPack

2) Run a terminal session from there
// On the left hand menu, it is under 'Access'

3) sudo ufw allow from xxx.xxx.xxx.xxx to any port 22
// Grab your public IP, replace xxx.xxx.xxx.xxx with that

4) Close that terminal session
5) SSH in as yourself, as usual
