yRouter

yRouter is an open source user space software router that is used in the Wireless GINI platform for node virtualization. It is an extension of the gRouter but with several changes, namely:

Removed dependencies on the packages that cannot be installed on OpenWrt.
Added link virtualization support through the tun interface.
Added support of deploying wlan interfaces that commodity wireless devices can connect to.

Installation

It is recommended to expand the storage capacity of the Arduino Yun if you are installing from source.

ssh into the Arduino Yun:

sshpass -p "arduino" ssh root@arduino.local

Install the following packages:

opkg update
opkg install binutils
opkg install make
wget http://downloads.arduino.cc/openwrtyun/1/packages/yun-gcc_4.6.2-2_ar71xx.ipk
opkg install yun-gcc_4.6.2-2_ar71xx.ipk
opkg install perl
opkg install screen

Install libslack-0.6.
Install yRouter:

cd /root/
git clone https://github.com/ahmed-youssef/yRouter.git
cd yRouter
./yInstall *StationID*

Usage

Usage is the same as the gRouter except for the new CLI commands, namely:

ifconfig add -dev tun0 -dstip dst_ip -dstport portnum -addr IP_addr -hwaddr MAC: Creates a tun interface on the yRouter.
- dst_ip: The IP address of the destination mesh station on the MBSS.
- portnum: The interface number of the tun interface on the other end of the virtual link.
- IP_addr : The virtual IP address of the tun interface.
- MAC : The virtual MAC address of the tun interface.
ifconfig add -dev raw0 -addr IP addr [-ssid SSID]: Creates a wlan interface on the yRouter.
IP_addr : The IP address of the wlan interface.
SSID: The SSID of the wlan interface. [TODO: Not implemented yet]
