Production and testing: Software setup

Before performing any production tests, various pieces of software need to be installed on Ben and PC, and configuration settings @@@

Register Ben host name

To simplify accessing the Ben via TCP/IP, its IP address should be registered in the hosts file on the PC. If the Ben is running OpenWrt, use the following command:

echo 192.168.254.101 ben >>/etc/hosts

If the Ben is running Jlime, the address would be as follows:

echo 192.168.1.202 ben >>/etc/hosts

If using the same PC with Bens running OpenWrt and Jlime, one may choose different host names depending on the distribution, and adapt the commands used in the production and testing process accordingly. For example,

echo 192.168.254.101 ben >>/etc/hosts
echo 192.168.1.202 jlime >>/etc/hosts

Ben system setup

The configuration setting described in this section are lost on each reset or reboot and either need to be entered again or a setup script running at boot time has to This needs to be done each time the Ben is booted.

Enable network access

Once the Ben has booted and started USB networking, the interface on the PC side is configured as follows:

ifconfig usb0 192.168.254.100 up

These are the settings for OpenWrt, assuming the network device is called "usb0". If using Jlime, the command would be as follows:

ifconfig usb0 192.168.1.200 up

Silence other 8:10 card users

Before running any of the ben-wpan utilities, other users of the 8:10 card slot have to be disabled. In a Ben running the regular OpenWrt or Jlime distribution, the only such user that is automatically started is the MMC kernel driver. The following command disables it:

echo jz4740-mmc.0 >/sys/bus/platform/drivers/jz4740-mmc/unbind

If a WPAN-enabled kernel has been installed, the AT86RF230 driver takes the place of the MMC driver. To disable it, run

echo spi2.0 >/sys/bus/spi/drivers/at86rf230/unbind

Start atrf-proxy

On the Ben, launch the proxy daemon. We pass the option -b to background it:

atrf-proxy -b

Ben software installation

Password-less remote access

To enable password-less remote access from the PC, setup to betwork access to the Ben and run the following command:

ssh ben 'cat >>/etc/dropbear/authorized_keys' <~/.ssh/id_rsa.pub
