Functions:

• mail hub
• network print server
• scan server
• mp3 file server
• system monitor
• proxy server

Here are the detailed steps needed to convert this $99 low power server into something useful:

Connect to the SheevaPlug console

* Connect the mini-USB/USB cable to a handy Linux box
* Load the appropriate kernel module:
sudo modprobe ftdi_sio vendor=0x9e88 product=0x9e8f
* Install gtkterm if you don’t already have it:
apt-get install gtkterm
* Configure gtkterm to connect to port /dev/ttyUSB1 (or whatever the SheevaPlug reports as, ls /dev/ttyUSB* to find out)
* Power up and watch the boot

= Start with Martin’s file system =

See the excellent description of getting the Debian/Lenny filesystem snapshot that Martin Michlmayr has provided:
http://www.cyrius.com/debian/kirkwood/sheevaplug/unpack.html

In addition to building an MMC card with the initial Debian file system, also upgrade the firmware to the one provided by user kwonsk at the PlugComputer.org forum. You will likely need to install the tftp server somewhere on your network — apt-get install tftpd and put the u-boot.bin binary in /srv/tftp/

= Initial steps =

* Login as root via the console change the root password: passwd
* Note the ip address (/sbin/ifconfig eth0ntpdate pool.ntp.org
* Change the ssh keys:

rm /etc/ssh/ssh_host*
ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key -N ""

* Unless you live in the same region as Martin, change /etc/apt/sources.list to use a closer Debian repository:
perl -pi~ -e 's/ftp.at/ftp.us/' /etc/apt/sources.list

* Same with timezone and locale: dpkg-reconfigure tzdata && dpkg-reconfigure locales

* Pick a hostname, I’m using lordshiva

perl -pi~ -e 's/debian/lordshiva/' /etc/hostname
hostname -F /etc/hostname


* Update/Upgrade
apt-get update && apt-get upgrade

* Add users adduser marc, etc

Setup the printer:


marc@lordshiva:~$ sudo hp-setup -i -a

Done.
marc@lordshiva:~$


Now you want to be able to manage the print server remotely via the web interface, so you’ll have to edit /etc/cups/cupsd.conf.

sudo $EDITOR /etc/cups/cupsd.conf
…find the three places that look like this:
Location /
Location /admin
Location /admin/conf

and add the following after the “Order allow,deny” lines:

Allow @LOCAL

Also change the line from:
Listen localhost:631
to
Port 631

Then restart the cups daemon: sudo /etc/init.d/cups restart

marc@lordshiva:/etc/sane.d$ sudo update-inetd --enable sane-port

Now all you need to do on the system you are going to scan from, edit /etc/sane.d/net.conf and add lordshiva.local (or whatever you named yours ;-)

Now to configure gnump3 is pretty simple, edit /etc/gnump3d/gnump3d.conf and set root = /media/mp3 or wherever the music is.

To start it up:

sudo gnump3d &

Then point a browser to http://lordshiva.local:8888/ and listen or download music. This comes in very handy for the kids when they need to load up their mp3 players.

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.

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.

I’ve been using the xorg.conf-ati.20060621 configuration at work with two monitors, but when at home the laptop didn’t degrade down to working with the one LCD monitor of the laptop. So, here is a new configuration that lets you switch between a single monitor mode (1024×768) or one large one (2048×768) that can be ‘slid over to’ by using the mouse. The key press is Control-Alt-+ (the + over on the side where the number entry is). On the laptop, it is Control-Alt-blue_Fn-?

Here the is xorg.conf file:

xorg.conf-ati-works-with-one-monitor.20060624

This hp/compaq nc6000 laptop/notebook that has an ATI card:


$ sudo lspci|grep VGA
0000:01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]


I have two head monitors working with both the ‘ati’ and the closed source ‘fglrx’ drivers.

Here are the configuration files:

Before you start hacking around with your xorg.conf, save a copy somewhere safe.

The current ‘released’ version of iPodder today is v2.0rc3 for Linux.

First off, go grab and install the the kit from http://ipodder.sourceforge.net/

You’ll need to use python2.3 instead of the default python which is v2.4. I already had it installed, but you many need to install it. Also the older version of the xmms python library needed to be installed, but the current version of libwxgtk2.5.3-python is needed.

The commands to install those packages is:

sudo apt-get install python2.3 python2.3-xmms libwxgtk2.5.3-python

Finally the PYTHONPATH needs to be extended to pick up the wx 2.5.3 libraries.

Either edit /usr/bin/iPodder to look like this, or just do it manually when you want to run iPodder:

export PYTHONPATH=/usr/lib/python2.4/site-packages/wx-2.5.3-gtk2-unicode/:$PYTHONPATH-unicode:$PYTHONPATH
cd /opt/iPodder
python2.3 iPodderGui.py

Enjoy!

straw refused to start with this error:

ItemStore.py:52:__init__: DB_RUNRECOVERY: Fatal error, run
database recovery – - PANIC: Invalid argument
Recovery Error: See README for details on how to recover data.

And the straw README says to do this:

$ db_recover -h $HOME/.straw -c -v
$ db_checkpoint -1 -v

Fair enough, but I don’t have those scripts installed db\_recover or db\_checkpoint. It turns out that they are in the libdb2-util package. (apt-get install libdb2-util)

Fortunately the recovery processed work fine.

Hi Dave!

This is Marc No-zell and I just listened to your Coffee Talk with
Richard Scoble. It sounds like Microsoft’s voice mail system is using
a descendant of the DECK-talk system that was created by DECK in the
1980s.

I’m creating this audio reply using the Festival Speech Synthesis
System on my Deb-ian GNU Linux laptop. Neener, neener, neener!

Well, thanks for the Coffee Notes!

Now I did do a little cheating here. Festival follows strict pronunciation rules and sometimes gets words wrong. For example my surname would be said as ‘nozzel’, so I spell it how I want it to sound. The same is true for DECtalk and DEC, which sounds like ‘dec-tork’ and ‘december’ (trying to be a little too clever ;-)
