 Connecting to the Kindle
For USB connection the device will default to 192.168.15.244
ifconfig usb0 192.168.15.201 && ssh email@example.com
To connect from Windows, you'll need a remote terminal application (two of the popular choices are PuTTy & WinSCP). Plug in your Kindle and wait for Windows to recognize the device. Go to Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings. Find the Local Area Connection # with small text "Unidentified Network, RNDIS/Ethernet Gadget" below, Right click on it and click properties, choose the Internet Protocol Version 4 (TCP/IPv4) and click Properties, click "Use the following IP address" and enter IP address 192.168.15.201, and 255.255.255.0 for the subnet mask, click OK twice. (take a look at the discussion page if you have problems finding the RNDIS connection) Open your remote terminal application, and connect as root to the address 192.168.15.244, leaving the password empty (or use mario if all else fails).
