The script is missing a bash shebang, since it does not work with dash, etc.

So it should start with:

#!/bin/bash

In line 68 you remove everything after the first "." AFAICS.

That is a problem if you give an IP address to the script.

The script will then take for example "192" as the node name if you give it a private ip address.

It works fine when given a DNS name though.

Hey, thanks for the feedback. You're right, will update the snippet ;)
