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!

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

<del>sudo debootstrap --arch=arm etch /etch-root <a href="http://ftp.de.debian.org/debian/">http://ftp.de.debian.org/debian/</a></del>

sudo debootstrap -–arch=arm etch /etch-root <a href="http://archive.debian.org/debian/" rel="nofollow">http://archive.debian.org/debian/</a>

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

NTFS Drive Access

http://technowizah.com/2006/11/debian-how-to-writing-to-ntfs.html

sudo apt-get install ntfs-3g

test mount

sudo mount -t ntfs-3g /dev/sda1 /mnt/windows -o umask=0,nls=utf8

if successful edit etc/fstab

/dev/sda1 /mnt/windows ntfs-3g umask=0,nls=utf8 0 0

 

So for the second time, something has happened to my NSLU2s primary disk – it scans ok, and there doesn’t appear to be any errors, though debian is refusing to boot right now and it’s a real pain to try and work out what is going on when there is no console and I’m getting next to nothing in the logs!

I’ve decided I’m going back to uNSLUng as it did everything I need, and caused me less pain….. that’s my task for this weekend!

I’ve got a document which describes everything I did to get debian up and running. I’ll edit and post this later in the week so it’s available to all who want to try debian on the NSLU2.
