# SSH to an instance from Windows

## SSH to an instance from Windows

You can use the [PuTTY](http://www.chiark.greenend.org.uk/~sgtatham/putty/) program as an SSH client to connect to your machine.

{% hint style="info" %}
This page gives you basic information about using PuTTY and PuTTYgen to log in to your provisioned machine. For more information on PuTTY, see the official PuTTY documentation.
{% endhint %}

If you are using Windows and you want to connect to your machine using a more Unix-like approach, you may want to consider [Cygwin](http://www.cygwin.com/) instead.

This topic shows you how to log in to your machine as the root user using the Windows program PuTTY.

When you provision a machine, the Machine Details page will display two different IP addresses: a public IP address and a private IP address. Take note of these IP addresses as **you will use the public IP to connect to your machine**.

To log in to your machine, follow these instructions:

* Open the PuTTY program.
* Type the public IP address of your provisioned machine in the **Host Name (or IP address)** field.
* In the **Category** panel on the left, expand the SSH section to expose the Auth settings.

* Click **Auth** to display the Options controlling SSH authentication panel.
* Click **Browse** and select the private key file you created. This is the private key you saved when you \[manually generating your SSH key in Windows]\(Manually Generating Your SSH Key in Windows.html).

* Click **Open** to open a PuTTY terminal session.

{% hint style="info" %}
The first time you connect to your machine, you may see a **PuTTY Security Alert** warning you that the host's key is not cached in the the registry. This is normal because PuTTY has never seen this machine before. Go ahead and click **Yes**.
{% endhint %}

#### Follow These Steps to Login

* At the `login as:` prompt, type "root" and press ENTER.

{% hint style="info" %}
**Note**: For Ubuntu based instances, the default username is "ubuntu".
{% endhint %}

```
login as: root
Authenticating with public key "rsa-key-20120104"
Passphrase for key "rsa-key-20120104":
```

* Type the passphrase you chose for this key and press ENTER.

You are now logged into your machine.

Once you are connected to a machine, you can start setting up your application.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.mnx.io/getting-started/ssh-from-windows.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
