# Accessing the Packet Squirrel

## Setup mode

On the first boot, the Packet Squirrel will boot into setup mode regardless of the position of the payload switch.

Setup mode enables the web UI and starts the setup process.

The Packet Squirrel web UI is accessible by connecting your computer to the Target Ethernet port (on the same side as the USB-C power connector) and navigating to <http://172.16.32.1:1471>

## Arming & Configuration mode

When the Packet Squirrel payload switch is set to position 4 (closest to the USB-A USB storage port), the Packet Squirrel will boot to Arming & Configuration mode.

In Arming & Configuration mode, the Packet Squirrel web UI is accessible, and the Packet Squirrel will launch a standard SSH server.  The web UI is accessible by connecting your computer to the Target Ethernet port (on the same side as the USB-C power connector) and navigating to <http://172.16.32.1:1471> , and the SSH server is accessible on the standard SSH port (22) at 172.16.32.1.

## Cloud C²

When the Packet Squirrel is able to access the Internet (`NAT`, `BRIDGE`, and `JAIL` network modes), the Cloud C² web-based SSH interface can be used to access the Packet Squirrel directly.

## Payload modes

Payloads are automatically executed depending on the position of the selector switch when the Packet Squirrel is booted. &#x20;

By default, the Packet Squirrel does not start the web UI or the SSH server when running a payload, but individual payloads can start and stop the web UI and SSH server with [UI\_START](/packet-squirrel-mark-ii/payload-development/duckyscript-for-packet-squirrel/ui_start.md) [UI\_STOP](/packet-squirrel-mark-ii/payload-development/duckyscript-for-packet-squirrel/ui_stop.md) [SSH\_START](/packet-squirrel-mark-ii/payload-development/duckyscript-for-packet-squirrel/ssh_start.md) and [SSH\_STOP](/packet-squirrel-mark-ii/payload-development/duckyscript-for-packet-squirrel/ssh_stop.md).

Network services are only available in network modes where the Packet Squrirel can access the network:  `NAT`, `BRIDGE`, and `JAIL` are supported.

{% hint style="warning" %}
Can't connect to the Packet Squirrel?  Make sure that the selector switch is in the right-most position for Arming & Configuration mode, and make sure that your computer is connected to the Target port!
