A Python script to programmatically shutdown a Buffalo TeraStation 3210DN NAS.
Written by Samuel FORESTIER for Stefano PICA.

Inspired from : <https://gist.github.com/HorlogeSkynet/703c1546ae2e70fc6cf6f04b8eb5a9d1>.

===

Usage documentation :

1. Install dependency : `pip3 install requests`

2. Configure credentials : Add to your `~/.netrc` something like :
'''
machine your.nas.ip.address (or host-name)
login admin
password A_VERY_SECURE_ADMIN_PASSWORD
'''

3. Run the script : `python3 TeraStation_Shutdown.py your.nas.ip.address` (or host-name)

This also works on a Buffalo TeraStation TS51210RH with no modifications
