Get the installer and check it

Download two files from tunnelnetos.com, then check that the installer is exactly the one we made.

Get it

On tunnelnetos.com, download the installer (it ends in .iso) and the short check file next to it (it ends in .sha256).

The check file holds a long code that only our exact installer matches. Checking it tells you the file wasn't damaged or changed on the way.

Put both files in the same folder.
On a Linux computer, open a terminal in that folder and type sha256sum -c followed by the name of the check file.
It should say OK after the installer's name. If it says anything else, don't use the file: download it again, and write to us if it still doesn't match.
