If you followed the previous tutorial on Windows, you may be wondering how to connect. If you have the GNU/Linux subsystem installed on your Windows host, it is as simple as using SSH -i, for users of Putty, I present a brief tutorial.
To connect, we must launch putty, and at the left, expand Connection, SSH, and select Auth:

Click browse and specify the path to the key file as described by vagrant, in my case C:/vagrant/ubuntu/.vagrant/machines/default/virtualbox/private_key:

Now we must specify the username vagrant by expanding Connection and clicking Data:

Finally, return to the session tab, and add the IP address and port. Type a name under Saved Sessions, and click Save.

Finally, click Open. Enter the password vagrant to login to the machine. I was so new when I created this tutorial (2015) I continue to mistype the name as Vagarant, which is plainly wrong.

In this way, vagrant provides a platform to work from, an identical dev-build box so to speak.
