dreamplug

My Dreamplug from Globalscale Technologies finally arrived yesterday and I'm just getting around to dig into it.

Things I've noticed:

• Shipped with Ubuntu/Jaunty preinstalled. Root password: nosoup4u



• kernel:
  Linux ubuntu 2.6.33.6 #1 PREEMPT Tue Feb 8 03:18:41 EST
  2011 armv5tel GNU/Linux



• Misc system info: /proc/meminfo,/proc/cpuinfo, dmesg and lsmod
  



• Only port open is ssh



• The dreamplug starts up as an open wifi access point that will route through either eth0 of the wired network or a ppp0 device. It is named DreamPlug-uAP-{last two octects of the uap0 MAC address} ie: DreamPlug-uAP-eb4c



• /etc/rc.local runs a script in ~root/init_setup.sh(!) It sets up the wifi as an access point, configures iptables for ip masquerade/ip forwarding, enables bluetooth and plays with the LED light brightness. See: init_setup.sh
  



• They didn't clean up .history -- lots of interesting stuff in there! Grab a copy before you do any commands as root. I lost the first 34 commands and curious what else they were doing. See: history.txt
  



• 
  Some commands they used and places to check for changes from default values:
  
  - uaputl sys_config
  - cp -rf /mnt/uaputl /usr/bin/uaputl
  - vi /sbin/wlan.sh
  - vi /etc/usbmount/usbmount.conf
  - mocp /media/usb1/EyesOnMe.mp3 (someone's favorite song, it gets played a number of times)
  - vi /etc/modprobe.d/blacklist-framebuffer.conf
  - vi /etc/modprobe.d/alsa-base.conf
  - cat /proc/asound/card0/codec
  - cat /proc/asound/card0/usbbus
  - cat /proc/asound/card0/usbid
  - cat /proc/asound/card0/pcm0p/info
  - vi /etc/ld.so.conf.d/libasound2.conf
  - vi /etc/java-6-openjdk/sound.properties
  - speaker-test
  - vi /etc/mke2fs.conf +5
  - vi /etc/asound.conf
  - arecord -f dat -D hw:3,0 -d 30 foo.wav
  - arecord -f dat -D hw:0 -d 30 foo.wav
  - arecord -f dat -D hw:1,0 -d 30 foo.wav
  - cat /proc/asound/cards
  - arecord -l
  - vi /etc/asound.conf
  - mocp BuzzingBee.wav
  - mv /etc/asound.conf /etc/asound1.conf
  - vi /etc/modprobe.conf
  - sudo apt-get install snd_pcm_dmix
  - vi /etc/asound1.conf
  - cp -rf /etc/asound1.conf /etc/asound.conf
  - play /home/havana.wav
  - vi /etc/udhcpd.conf
  



• There are two kernel modules (mcypt.ko & sd8xxx.ko) sitting in ~root/ On how to use them (not that I've tried yet), try here on openplug.org. See: mcypt.ko and sd8xxx.ko
  



• Packages installed by default: dpkg.txt
  



• Things to do:
  - apt-get update && apt-get upgrade (carefully don't trash possibly changed config files)
  - install emacs (sudo apt-get install emacs)
  - change password
  - create user accounts
  - add users to sudousers (visudo)
  - install ssh keys (ssh-copy-id user@ubuntu.local)
  - change the hostname from ubuntu.local to morpheus.local (to go with my SheevaPlug named lordshiva.local) (edit /etc/hostname and /etc/hosts)
  - play with USB webcam & motion
  - setup ftp/nfs for local file sharing
  - carefully consider upgrading to more recent versions
  - look at using as a wifi client
  - try pairing bluetooth headset
  - try pairing android phone -- file transfers? remote control?
  - install cups
  - install gnump3d (needs make)
  - install munin to monitor performance (is this going to kill my
  internal sd storage?)
