Unban an IP from fail2ban using interactive mode

the fail2ban-client has an interaction mode which will make it easy to unban an IP without many complications. To access interactive mode use:

$ fail2ban-client -i

once in interactive mode type ssh, or in some cases sshd (this was the case in my installation)

Recommended ufw settings for your https site

allowing ssh

NOTE: the default port for ssh is 22, and when you allow ssh below, that's the port that will be allowed. If you configured your vps to login using a different port, you must use sudo allow <portnumber> instead (i.e. sudo allow 2222 if your port is 2222).

- This is very important, or you will lock yourself out of ssh!
