# SSH Access

Skynode and AI Node both run the linux-based AuterionOS. SSH can be used to access the operating system during the development process.

The following instructions require a connection to Skynode as described on the following page:

{% content-ref url="../skynode/advanced-configuration/connecting-to-skynode" %}
[connecting-to-skynode](https://docs.auterion.com/hardware-integration/skynode/advanced-configuration/connecting-to-skynode)
{% endcontent-ref %}

For AI Node follow the instructions on this page

{% content-ref url="../ai-node/connectivity/usb-network-connection" %}
[usb-network-connection](https://docs.auterion.com/hardware-integration/ai-node/connectivity/usb-network-connection)
{% endcontent-ref %}

## When to use SSH

SSH provides access to the mission computer of Skynode, and to that extent provides full control over Skynode *and* the flight controller.

## SSH Connection

Use the `ssh` command to connect to the SSH server on devices running AuterionOS:

<table data-view="cards"><thead><tr><th>Device</th><th>IP Address</th><th>Username</th><th>Password</th><th>Development Connection</th></tr></thead><tbody><tr><td>Skynode</td><td>10.41.1.1</td><td>root</td><td>auterion</td><td>USB-C</td></tr><tr><td>AI Node</td><td>10.41.2.1</td><td>root</td><td>auterion</td><td>micro-USB</td></tr></tbody></table>

{% hint style="warning" %}
SSH root access is only available in the AuterionOS development image. For security reasons it should not be used on released products. For more details see the page [Types of AuterionOS Images](https://docs.auterion.com/hardware-integration/auterionos-system-guide/types-of-auterionos-images). [Submit a ticket](https://auterion.zendesk.com/hc/en-us) to request a release build of AuterionOS with SSH root access disabled to deploy in production.
{% endhint %}

## SSH Access Restrictions

It is possible to change the password, as well as include your own SSH keys into an AuterionOS image. See the section about [configuring and packaging AuterionOS](https://docs.auterion.com/hardware-integration/auterionos-system-guide/packaging-auterionos-image) for more details.

Furthermore the use of the standard username and password mentioned above is completely disabled in [production images of AuterionOS](https://docs.auterion.com/hardware-integration/types-of-auterionos-images#production-and-development-images). Skynodes running production images will only allow access when using SSH keys that were packaged into AuterionOS beforehand.
