Dreamplug - an introduction

Overview

So, you have just received your Dreamplug. If you are unfamiliar with embedded devices, getting started can be daunting. This document is aimed at getting started with the Dreamplug.

Before we start, you will nedd a SSH client. If you are a windows user you can use PuTTY from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
The installer is simplest choice. For UNIX/MAC you can use ssh. If you do not know what ssh is then it is time to do some google searching.
You will also need a PC (Windows, UNIX or MAC) that has Wifi support. In its initial state the options for connecting to the Dreamplug are Wifi or the serial JTAG. The later versions of the Dreamplug have been modified to also support DHCP connections on both ethernet ports.This document assumes you do not have a JTAG.

First things

Connecting via SSH
The Dreamplug user guide contains a detailed description of how assemble the Dreamplug and how to connect via WiFi. The Dreamplug provides an unsecured access point with a name of Dreamplug-uAP-xxx, where 'xxxx' is the last 4 digits of the MAC address.
Once you have a WiFi connection, you can access the Dreamplug via SSH (puTTY or similar).
The IP address of Dreamplug is 192.168.1.1 If this address clashes with another device on your network you will need to switch off that device.
Log on as user root, password is nosoup4u

Upgrade your distribution
This not required. 
  apt-get update
  apt-get dist-upgrade
  apt-get autoremove
  apt-get autoclean
Set the time zone
dpkg-reconfigure tzdata
Reset the SSH keys
dpkg-reconfigure openssh-server
Set the password
passwd
Enabling the ethernet connection nearest the end of the plug
Edit the file '/etc/network/interfaces' e.g.
# nano /etc/network/interfaces
Append the lines 
auto eth1
iface eth1 inet dhcp
OR if you know what you are doing (else ignore this) then: 
auto eth1
iface eth1 inet static
        address 192.168.0.38
        netmask 255.255.255.0
        broadcast 192.168.0.255
        gateway 192.168.0.1
        hwaddress ether xx:xx:xx:xx:xx:xx
Save the file

Test the interface.
Connect a cable from your router/firewall to the ethernet connection nearest the end of the plug. 
# ifdown eth1
# ifconfig eth1 down
# ifup eth1
# ip addr show eth1
Note the IP address, you should now be able to connect to this address with putty.
Securing the wifi
Edit the file '~/init_setup.sh' e.g.
# nano ~/init_setup.sh
Look for the lines like: 
/usr/bin/uaputl sys_cfg_ssid $SSID
/usr/bin/uaputl bss_start
and change them to: 
/usr/bin/uaputl sys_cfg_ssid $SSID
##
## start of added lines ##
## This uses either WPA or WPA2 security
/usr/bin/uaputl sys_cfg_protocol 40
/usr/bin/uaputl sys_cfg_wpa_passphrase 'mydreamplug'
/usr/bin/uaputl sys_cfg_cipher 8 8
## end of added lines ##
##
/usr/bin/uaputl bss_start

Devices
On Debian the peripherals are mapped as follows:
  • Internal uSD - /dev/sda (always)
  • External SDHC - /dev/sdb (always)
  • USB Ports and ESATA /dev/sdc, /dev/sdd and /dev/sde (no specific order)
The Dreamplug is configured to autmount SD cards and USB drives when they are inserted.
