DreamPlug: motion activated webcam

The webcam tool 'motion' is pretty nice, but it needs some tweaks to the base Ubuntu/Jaunty running the DreamPlug.

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...

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?)
  

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

hp2133 netbook running Ubuntu

hp2133 netbook running Ubuntu, originally uploaded by marcn.

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

Ubuntu/lucid on hp2133

Tonight I wiped my hp2133 running Ubuntu/karmic and installed lucid.

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.

hp 2133 update

I was going to use SLED10 for a while on my hp2133 mini-note, but getting updates is problamatic. If you call HP support within 30 days they will send you a SLED10 restore CD at no cost. This CD is one of those boot-and-wipes-the-disk variety, so be aware. This CD is different from the ISO you can download from HP (here).

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.

How to connect a Samsung Flipshot U900 to Ubuntu/Linux

First purchase a USB cable that works with the Samsung Flipshot U900 -- I ordered one from 3GCables.com for $8.95 (and $6.95 s/h)

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


USB to Serial Adapter for Ubuntu

I recently received an updated laptop at work -- a nice hp nc6400 notebook. Unlike the previous nc6000, this new on does not include a serial port which is problematic for the Garmin to serial cable I have. I ordered from CompUSA a USB to Serial Adapter by CablesToGo (model 26886) and it works great out of the box on Ubuntu/Feisty.

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.

gpicsync on Ubuntu/Feisty

GPicSync is a very nice cross-platform tool to match up photos with GPS locations. However it requires a package that isn't included by default by Ubuntu/Feisty.

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

Convert audio from WMV files to MP3

A while back some radio station website or somewhere had a video in WMV of KT Tunstall performing Black Horse and the Cherry Tree and I wanted the music for a plane ride today.

Usually I'd use vsound, I've been able do save the audio track of a video in realplayer, but for some reason it wasn't working for gxine.

Anthony Barker's blog had the concise steps needed to use mplayer to grab the sound.


mplayer -dumpfile outfile.dat -dumpstream some-video.wmv

mplayer -vo null -vc null -ao pcm -ao pcm:file=audio.wav outfile.dat

lame audio.wav audio.mp3

rm outfile.dat


Building F-Spot from source on Ubuntu

The instructions How to Build F-Spot from HEAD are mostly correct for Ubuntu/Edgy and Ubuntu/Feisty, but leave out a number of packages that need to be installed before autogen.sh is run.

Be sure to also install the following packages:

sudo apt-get install mono-devel \
libglib2.0-dev libmono-dev libmono-system-runtime2.0-cil \
libexif-dev libgnomeui-dev liblcms1-dev libgphoto2-2-dev \
libusb-dev

And instead of make install, use make -k install since it will attempt to run scrollkeeper which attempts to update /var/lib/scrollkeeper/scrollkeeper_docs.

The offending line is: scrollkeeper-update -p /var/lib/scrollkeeper -o /home/marc/unstable/f-spot/share/omf/f-spot

Ubuntu/Edgy & Belkin Wireless G (F5D7010) ver 5100

The Belkin Wireless G Notebook Card (F5D7010) ver 5100 works great out of the box with Ubuntu/Edgy.

Unfortunately in the MythTV system I want it for has an old PCI/PCMCIA adapter that only accepts 16-bit PCMCIA cards, so this 32-bit one won't fit.

Below is some info that my help you debug your configuration:

It uses the ath_pci kernel module.

Most exciting upgrade to Ubuntu/Edgy

This morning I had a free hour and this is how I upgraded my hp compaq nc6000 laptop from Ubuntu/Dapper to Ubuntu/Edgy. After updating /etc/apt/sources.list to point to the edgy repos...

sudo apt-get update && sudo apt-get -dy dist-upgrade && sudo apt-get dist-upgrade

Well there was a conflict between x11-common and xinit which both wanted to provide the man page XSession.5.gz.

11:45am Wendy calls me and says the school just called and Griffin is in a ambulance on the way to the hospital and to meet her there. He accidentally ate something that contained pineapple -- to which he has a severe allergic reactions to.

11:49 I'm on the road approaching the hospital and get a call on my cell phone. The woman says she is the school nurse and starts saying my son is having an allergic reaction. I interrupt her and say 'Yes, I just talked to my wife and I'll meet the ambulance at the hospital'. She says 'Well, your son is sitting here with me in my office.' Then we realize she is the school nurse from a different chool and is talking about Trevor who is having an allergic reaction! Trevor had his bee/wasp allergy shot earlier this morning and is reacting to that. Since he too was having difficulty breathing, he too is sent via ambulance to the ER.

12:05 -- Wendy and I both arrive at the ER before either of the kids do. Explain to the ER admitting person that yes both boys are ours, they are coming from different schools, with the same problem (allergic reaction, breathing difficulty), but different reasons (food allergy vs reaction to allergy desensitizing injection).

Long story short, after evaluation, some benedril and alburterol breathing treatments, we were sent home.

Around 3pm I worked through a few iterations of apt-get update, apt-get dist-upgrade, apt-get -f install, aptitude dist-upgrade, I have a fully upgraded from Ubuntu/Dapper to Ubuntu/Edgy.

There are a bunch of new, interesting packages to take a look out. The list is here: EdgyConfiguration

Now that was a stressful upgrade.

Converting Creative MuVo WAV to a 'real' WAV

I recently recorded an event using my little Creative MuVo TX FM mp3 player. It created a 22M WAV file of reasonable quality, but lame and audacity had problems converting it to an MP3 file.

The work around is to open the original wav file with audacity and then File->Export as WAV. The resulting wav file is about four times as large, but is in a usable format. From there use your favorite tools to create an OGG or MP3 file.

It appears the problem has to do with the way the MuVo encodes the wav:



VOC001-original.wav: RIFF (little-endian) data, WAVE audio, IMA ADPCM, mono 8000 Hz

My wife had an unused Logitech Stereo USB Headset 250 kicking around the house that I took into the office today. Joy of joys! Ubuntu/Dapper recognized it and both the headset *and* microphone work out of the box.

Just like Microsoft Windows ;-)

Democracyplayer on Ubuntu/Dapper

The good folks at GetDemocracyNow.com provide debian packages for Ubuntu/Dapper, but didn't get the dependencies quite right. After intalling the two democracyplayer packages from their Ubuntu download page, I needed to also install the following packages:

$ sudo apt-get install libboost-python1.33.1 libgtk-mozembed-ruby mozilla-psm

There is a ton of great content!

Moving photos around behind f-spot's back

I've been using f-spot since it showed up in Ubuntu/Breezy and have been keeping all my photos in a directory structure like this:

/PHOTOS/Photos/2006.06.30/
/PHOTOS/Photos/2006.07.01/

But sometimes I've forgotten to unclick the "Copy file to the Photos folder" box in the photos import dialog and end up with photos under ~/Photos/. Recently I checked and found there were almost a gigabytes worth of photos under there.

So this is what I did to move them to under /PHOTOS/Photos/ and keep all the tags and metadata correct.

• Back up /home and /PHOTOS to an external USB. I love rsnapshot.
  $ rsnapshot daily
  


• make an extra backup of the f-spot database
  $ cp ~/.gnome2/f-spot/photos.db photos-backup.db
  


• Start poking around the f-spot database and updating it.
  $ sqlite3 ~/.gnome2/f-spot/photos.db
sqlite> .schema photos
CREATE TABLE photos ( id INTEGER PRIMARY KEY NOT NULL,
time INTEGER NOT NULL,
directory_path STRING NOT NULL,
name STRING NOT NULL,
description TEXT NOT NULL,
default_version_id INTEGER NOT NULL
);

  


• See how many photos are in ~/Photos...
  sqlite> select count(*) from photos where directory_path like '/home/marc/Photos/%';
260

  


• Take a look at a few of them to see the path names...
  sqlite> select directory_path from photos where directory_path like '/home/marc/Photos/%' limit 0,10;

  


• Update the pathname to my prefered one. I've added an 'a' to the end just so I won't overwrite an existing directory.
  sqlite> update photos set directory_path = "/PHOTOS/Photos/2006.06.22a" where directory_path = "/home/marc/Photos/2006/6/22";
sqlite> .quit

  


• Make the directory and move the files to the new location...
  mkdir /PHOTOS/Photos/2006.06.22a
mv -v /home/marc/Photos/2006/6/22/HPIM117* /PHOTOS/Photos/2006.06.22a

  

Repeat for each directory. I did it all within emacs' shell so cut-n-paste made it a snap.
