This blog turned 10 years old on March 5th, 2012. It started life as a humble blosxom script and stayed like that for two years when I migrated to a self-hosted wordpress blog. Since I’ve been tracking late in 2007, there has been 180,000 page views — a good percentage is probably spammers.

Here are my move viewed blog entries:

1. messing around with tiles (13-Aug-2004; 16,153 hits) — a silly little post about using the taprats java app to generate some interesting titles. It is also where I got the favicon for nozell.com.
2. family pictures — including one of me naked! (4-May-2003; 7,560 hits) — Seems lots of people are searching for naked photos on the internet. Who knew? The entry has some bitrot, but I had scanned some old photos as part of a genealogy project. Here is the photo of me butt naked.
   
3. Getting started with the SheevaPlug (12-May-2009; 7,158 hits) — finally a geek-related entry! I’m still somewhat happy with LordShiva.local, but it sometimes flakes out losing the root filesystem. Its backup function has been moved to a DreamPlug.
4. flickr upload for gnome’s nautilus (4-Sep-2004; 6,077 hits) — Back in the Debian/Sarge days I wrote a little Nautilus script to upload flickr photos. It got some link-love from flickr. Sadly the script is lost to the ages.
5. I’ve seen things, I’ve seen them with my eyes… (5-Mar-2004; 4,901 hits) — damn earworm by the excellent Weebl. Surprisingly the link is still good. Best part of the song? Kuala Lumpur!
6. Some tips to (re)install grub on an HP ProLiant server (8-May-2004, 4762 hits) — Back in the day HP ProLiant with SmartArray controllers, Red Hat and grub didn’t love each other as much as they do today. My notes were popular for a while, less so over time.
7. Logitech USB headset & Ubuntu/Linux (13-Sep-2006; 4,263 hits) — evidence that random devices work out of the box on Linux just like it usually does on Windows.
8. hp 2133 update (4-Jun-2008; 3,799 hits) — described some problems installing various distros of Linux on my cute little hp2133 netbook. Since then Ubuntu has been running on the hp2133 just fine and has ubeen upgraded through Oneric. Now it is off at college with Son #2 who uses it for notetaking in class.
9. SheevaPlug customizing pre-installed Ubuntu/Jaunty (17-May-2009; 3,392 hits) — misc notes on the SheevaPlug when it was running Ubuntu/Jaunty. Currently it is running Debian/Squeeze mainly because Ubuntu dropped support for the ARM CPU it uses.
10. SheevaPlug is now my main home server (26-Jun-2009; 2,916 hits) — A write up on what the SheevaPlug was hosting in my home datacenter. All those functions have moved to the newer and more capable DreamPlug.

The other big milestone is I’ve had the nozell.com domain for 15 years — 6-Feb-1997. I have children that are younger than that domain!

]]> http://nozell.com/blog/2011/04/14/my-plugcomputer-datacenter/feed/ 0 http://nozell.com/blog/2011/04/13/dreamplug/ http://nozell.com/blog/2011/04/13/dreamplug/#comments Thu, 14 Apr 2011 01:17:37 +0000 Marc Nozell http://nozell.com/blog/?p=938 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

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 ""
Generating public/private dsa key pair.
Your identification has been saved in /etc/ssh/ssh_host_dsa_key.

+-----------------+


* 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.

Now setup munin-node to know what to monitor locally. I like to run munin-node-configure with the –shell option to see what my choices are and then cut-n-paste the ones I’m interested in.


marc@lordshiva:~$ sudo munin-node-configure --shell --families=auto && sudo munin-node-configure --shell --families=contrib && sudo munin-node-configure --shell --families=manual

And then just pick: (jump into a root shell first, sudo -i)

ln -s /usr/share/munin/plugins/apt /etc/munin/plugins/apt
ln -s /usr/share/munin/plugins/apt_all /etc/munin/plugins/apt_all

ln -s /usr/share/munin/plugins/port_ /etc/munin/plugins/port_www
ln -s /usr/share/munin/plugins/uptime /etc/munin/plugins/uptime


And restart munin-node

sudo /etc/init.d/munin-node restart
