Do this:

• Enable the motion daemon. sudo emacs /etc/default/motion and set start_motion_daemon=yes
• Allow for non-localhost access to the web interfaces. sudo emacs /etc/motion/motion.conf and change the lines to match: webcam_localhost off and control_localhost off
• Create the default directory to hold the jpg and swf files. sudo mkdir /tmp/motion && sudo chown motion.motion /tmp/motion
• Restart the motion daemon. sudo /etc/init.d/motion restart
• Fire up a browser and point it to the DreamPlug’s port 8080 (say http://morpheus.local:8080) and then follow the link to config then list. From there you’ll probably need to set auto_brightness to on.
• Now look at the video on port 8081 (say http://morpheus.local:8081)

After a while of it running, you don’t need the browser to be on the page, take a look in /tmp/motion to find all the JPG images and SWF ‘movie’ files. Eventually I’ll probably change the directory to live on one of the USB disks…

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?)

14-Apr 10:50am Update: DreamPlug discussion on reddit submitted by sub2k1

hp2133 netbook running Ubuntu, originally uploaded by marcn.

Okay it was getting late and took a lazy photo with my droid…

The only pain was of course getting the wireless card to work. That simply meant getting the Broadcom firmware into /lib/firmware/b43

The instructutions on http://wireless.kernel.org/en/users/Drivers/b43 were right on. You will need to build b43-fwcutter from source pulled from the git repo, but the commands are provided.

I made sure the nfs-kernel-server was also installed on where the disks were and added to /etc/exports something like:

/home/Music lordshiva(ro,sync,no_subtree_check)

and ran sudo exportfs -av

The on the SheevaPlug:

sudo mkdir -p /nfs/Music
sudo mount homeserver:/home/Music /nfs/Music

And updated /etc/gnump3/gnump3.conf to point to /nfs/Music

updating what munin monitors

Running the following commands will make some recommendations on additional things munin can monitor.

# munin-node-configure --shell --families auto
# munin-node-configure --shell --families contrib
# munin-node-configure --shell --families manual

Just cut-n-paste the ones you want to enable into a root shell. Remember to restart the daemon too.

SheevaPlug as a mini-printserver

The pre-installed Ubuntu doesn’t include any kernel modules, but thought I’d try using the SheevaPlug as a mini-print/scan server for my hp PSC 1510 All-in-One printer/scanner.

Hmm, during the install I plugged in the printer and checked dmesg to see if it was recognized. The lanmap process appears to have had a problem allocating memory:

When I tried to killall lanmap, ssh sessions hung. I could get in via console still. The network seemed to be a bit wonky, so rebooted.

Hmm, scary kernel messsages

This is after the reboot and seems to be when hal is starting up on install. Install is slowing continuing.

I’ve removed just hal, apt-get --purge remove hal

Hmm, now it appears that the pre-install Ubuntu/Jaunty doesn’t include any kernel loadablel modules for things like USB printers. Time to install stock Debian on this beastie.

First up — installing Ubuntu/Hardy. On the boot prompt, you’ll have to add xforcevesa or the video will flake out. Using an external USB CD/DVD drve, the standard Ubuntu CD boots and starts the install, but after resizing the SLED10 partition down to 10G, the install fails with the following message:

Next up — Fedora 9. Again using an external CD, the install starts up well, but then soon fails when trying to locate the CD containing the install RPMs. I has been a while since I’ve used Red Hat on the desktop, so I’ll give Fedora another try later. (And it will make the Red Hat folks at GNHLUG happy ;-)

Next up — Ubuntu/Hardy Alternative Install CD. This version uses the tried-and-true debian install process and this time it works great!

With the stock Ubuntu/Hardy it finds and configures the wired network, graphics, audio (except the earphone jack), MMC disk. The Broadcom Wifi does not however and needs to use the ndiswrapper with firmware downloaded from the hp.com support site.

The post-install steps for Ubuntu/Hardy to get the WiFi working can be found on “WifiDocs/Driver/bcm43xx/Feisty No-Fluff”.

For the hp 2133, the steps are:

1. I found on my Ubuntu/Hardy that the bcm43xx module was already on the blacklist so the first line wasn’t necessary. See line 32 of /etc/modprobe.d/blacklist. You’ll still need to install ndiswrapper-utils-1.9 and create a tmp directory to unpack the wireless firmware.

   
# NOT NEEDED echo 'blacklist bcm43xx' | sudo tee -a /etc/modprobe.d/blacklist

   sudo apt-get install ndiswrapper-utils-1.9
mkdir ~/bcm43xx; cd ~/bcm43xx


2. Since my hp 2133 has a Broadcom Corporation BCM4312 802.11a/b/g (rev 02), use Step 2a which downloads from Hewlett-Packard the Windows firmware for the Broadcom Corporation BCM4312 802.11a/b/g (rev 02)

   
sudo apt-get install cabextract
wget ftp://ftp.compaq.com/pub/softpaq/sp34001-34500/sp34152.exe
cabextract sp34152.exe


3. Step 3 is to install the firmware using ndiswrapper. My /etc/network/interfaces file already had an entry to the ‘lo’ device, so didn’t need to do that. Also ran into problems trying to load the modules on boot, so I don’t load ndiswrapper from /etc/modules. Also I didn’t bother to edit /etc/default/wpasupplicant because on my home wireless network. I don’t use authentication — wireless access is locked down by MAC address at the wireless router.

   
sudo ndiswrapper -i bcmwl5.inf
ndiswrapper -l
sudo depmod -a
sudo modprobe ndiswrapper

   #NOT NEEDED sudo cp /etc/network/interfaces /etc/network/interfaces.orig
   #NOT NEEDED echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces

   sudo ndiswrapper -m

   #NOT NEEDED by me echo 'ndiswrapper' | sudo tee -a /etc/modules
#NOT NEEDED by me echo 'ENABLED=0' | sudo tee -a /etc/default/wpasupplicant


4. As the wiki page mentions, there is a bug in Ubuntu/Hardy related to the ndiswrapper and ssb loadable modules, so after every boot, I do the following steps which I put in a little script, enable-wifi

   
#!/bin/bash
# This is ~/bin/enable-wifi
ndiswrapper -l
sudo depmod -a
sudo modprobe ndiswrapper
sudo rmmod ssb
sudo rmmod ndiswrapper
sudo modprobe ndiswrapper
sudo modprobe ssb


   After a few seconds the NetworkManager applet will start looking for wifi networks and automatically connect.

   I’ve tried following the wiki’s instructions on making it permanent, but found that there were nasty kernel messages about the ssb loadable module dying and preventing ndiswrapper from loading.

The next post install step is to fix the audio driver. The sound card works okay, but doesn’t turn off the speakers when a headphone is plugged in. The other great wiki page, https://wiki.ubuntu.com/LaptopTestingTeam/HP2133 has the solution. Essentially download and install alsa-driver-1.0.16_linux-headers-2.6.24-17-generic-1_i386.deb.

Why hasn’t a fix been pushed into the repositories is unclear.


sudo mv /lib/modules/2.6.24-17-generic/ubuntu/sound/alsa-driver \
/lib/modules/2.6.24-17-generic.ubuntu.sound.alsa-driver.bak
sudo ln -s /lib/modules/2.6.24-17-generic/kernel/sound/ \
/lib/modules/2.6.24-17-generic/ubuntu/sound/alsa-driver


Although it may look like a lot of work, it wasn’t that difficult. If you have problems, check back to the source wiki pages.

The default setting for the phone was to ask how it should present itself when connected via USB. The options are “Ask on Plug”, “Copy To/From Card”, “Sync Music” or “Modem”
Since I’m always going to use it like a usb-storage device, I changed it to always use “Copy To/From Card”.

• 5. Settings & Tools
• 8. USB Auto Detection
• Change to “Copy From/To Card’.

Now you can copy files to /media/disk. My top level directory looks like this:


$ ls /media/disk/
my_files my_flix my_music my_pix my_sounds


All I needed to change is the serial port to use, so:

gpsbabel -t -i garmin -f /dev/ttyS0 -o kml,points=0,line_color=ff0000ff -F waypoints.kml
gpsbabel -t -i garmin -f /dev/ttyS0 -o gpx -F waypoints.gpx

becomes:

gpsbabel -t -i garmin -f /dev/ttyUSB0 -o kml,points=0,line_color=ff0000ff -F waypoints.kml
gpsbabel -t -i garmin -f /dev/ttyUSB0 -o gpx -F waypoints.gpx

FWIW, it uses the pl2303 kernel module.

1. Download GPicSync from http://code.google.com/p/gpicsync/

2. Unpack it: tar zxf Linux-GPicSync-0.91.tar.gz

3. Move to the directory it created: cd Linux-GPicSync-0.91

4. Set the GUI and command line versions of the program executable: chmod +x gpicsync-GUI.py gpicsync.py

5. Install the Ubuntu/Feisty package python-wxgtk2.8 which provides the python bindings for the wx library and the exiftool: sudo apt-get install python-wxgtk2.8 libimage-exiftool-perl

6. Run the program and start geotagging photos: ./gpicsync-GUI.py
