Tor Box

Tor Box project aims to build a Tor hardware router base on a Olimex A20 OLinuXino LIME board.

One leitmotiv : torify them all.

Design

Build

The build process is currently tested on a fresh Debian Jessie net install. You need at least 4GB of RAM for the development machine (xz image compression require a lot of RAM).

Since the build process heavily modify the system (change APT repositories, install arm as foreign architecture…), it's better to use VirtualBox to create a virtual machine.

Full automated installation preseed file available. The created machine use Avahi and so can be joined with SSH on torbox-dev.local. Root password is root.

To setup development system, just copy this folder into dev target (with rsync for example), then run make dev on the created folder.

To build the LIME image (build/torbox.img, 4GB), run make img, or make img_compress for the XZ compressed version (build/torbox.img.xz, ~100MB).

Deployment

You need a 4GB or more SD card. The provided Makefile assume you have your SD card available under /dev/sdd. Modify it if not.

You can flash your SD card with dd if=torbox.img of=/dev/sdd (or with make img_flash if on the dev machine). If you want to use the compressed image without uncompressed it on disk, use unxz -c torbox.img.xz | dd of=/dev/sdd.

For development, because flashing 4GB on a SD card is slow and tedious, you can format your SD card with make format and then sync it content with make flash after a new build (or even make rootfs_sync if the Torbox is joinable from the development machine, avoiding the SD card switch).

Usage

Use the LIME with UART serial port to debug the boot process (/dev/ttyUSB0, 1152000 bauds, 8 data bits, 1 stop bit, no sw/hw handshake).

You can connect to the mini-USB port, providing DHCP connectivity. Torbox is available with SSH on 10.0.0.1.
