As promised, what follows are my installation notes for debian on the NSLU2.

These are pretty much just a dump of everything I did to get things working.  Hopefully these may be of use to someone as a good reference guide!

Apologies that this isn’t structure too well, I just wanted to get it all down for posterity

Having said that…. here comes the mega post – try not to fall asleep

 

——————————

• Download image:http://www.slug-firmware.net/d-dls.php
• put slug into upgrade mode
• use uplsug/windows equivalent to upgrade flash
• When complete insert disks – reboots automatically.

• Should be able to SSH into NSLU2 shortly after
  • Username: installer
  • Password: install

• If connecting via putty in windows, change to the UTF8 conversion mode – console looks much better.
• Follow through installation – takes about 4 hours!
• Nearing end of installation it asks for server type.  I chose the following
  • Standard pre selected
  • Selected file server as additional

This is enough to install Debian, so then it’s onto all the optional and more useful parts!

Note ID of disk

lrwxrwxrwx 1 root root  9 May  5 21:07 usb-Seagate_External_Drive_SW063423123-0:0 -> ../../sda

lrwxrwxrwx 1 root root 10 May  5 21:07 usb-Seagate_External_Drive_SW063423123-0:0-part1 -> ../../sda1

lrwxrwxrwx 1 root root 10 May  5 21:07 usb-Seagate_External_Drive_SW063423123-0:0-part5 -> ../../sda5

e.g. id is = usb-Seagate_External_Drive_SW063423123-0:0

 # The time in seconds a disk has to be idle before it is spundown.
 # Do not use a value that is to small (less than 3600) unless you
 # know what you are doing.
 idle-time = 3600

 # Turn this on if you want spindown to log messages using syslog.
 # You will not want to turn this on if you are trying to spindown
 # the disk with the root filesystem on.
 syslog = 0

 [Disk 0]
 id = usb-Seagate_External_Drive_SW063423123-0:0
 spindown = 1
 command = sg_start --stop

TownkyMedia

Twonky requires old LIBC version – easiest way to get this running is to install an etch environment, as follows.

apt-get install unzip

sudo apt-get install debootstrap

sudo debootstrap --arch=arm etch /etch-root http://ftp.de.debian.org/debian/

sudo debootstrap -–arch=arm etch /etch-root http://archive.debian.org/debian/

mkdir /etch-root/usr/local/twonkymedia
cd /etch-root/usr/local/twonkymedia
unzip /root/twonkymedia-armel-glibc-2.2.5-4.4.11-20090108.zip
chmod 700 twonky* cgi-bin/* plugins/*
cd /root

 

 

 

vi /etc/init.d/twonkyStartEtch

 

#!/bin/sh
set -e
action="$1"

case "$action" in
*start)
mount | grep -q " on /etch-root/proc " || mount --bind /proc /etch-root/proc
#    mount | grep -q " on /etch-root/home " || mount --bind /home /etch-root/home
;;
esac

chroot /etch-root /usr/local/twonkymedia/twonkymedia.sh $action || true

case "$action" in
stop)
mount | grep -q " on /etch-root/proc " && umount /etch-root/proc
#    mount | grep -q " on /etch-root/home " && umount /etch-root/home
;;

Esac 

Save and Close

chmod +x twonkyStartEtch

 

cd /etc/rcS.d/

ln -s /etc/init.d/twonkyStartEtch S97twonky

cd /etc/rc0.d/
