Cloning a working Debian Slug (NSLU2)
some notes for when I have to do it again


1) Copy the slug firmware and USB harddrive contents from a working Slug to a new Slug
2) Modify files to set a new LAN address - in this case change from to
3) Modify with new files to test new applications etc.

I bought a "new" Slug off eBay and wanted to clone the working Slug I had spent hours setting up to the new hardware.

Clone the USB hard disk

1) Copy all files from the existing USB hard disk (57 GBytes) to a folder in Linux on VMWare on my Mac
2) Plug a new USB hard disk (80 GBytes) into the Mac and drag and drop all files onto this - I think this disk was Ext2 not Ext3 - not sure if it matters.
3) Test this disk on the original Debian Slug - it works!

Copy the Firmware

On the original Slug do -
cd /data <--on the hard disk
cat /dev/mtdblock* > image.bin

plug the disk into the Mac and copy the firmware file image.bin to a folder in Linux on the Mac

Set the Slug for firmware upgrade
- hold the reset and power switches on - count to 10 - see the Ready/Status flashing between 2 colours
(I think it was red and green in the new Slug (it must be an old model) - dark orange/light orange in more recent ones)

In a Linux terminal cd to the folder containing image.bin in the Linux on the Mac
do -
upslug2 --image="image.bin"

Wait 5 minutes after it has loaded - switch off - plug in the hard disk - power up - disconnect the old slug from the LAN since both are at at present
In the Mac terminal - ssh root@ - it works!

Now change to

There are config files all over the place !

These are the ones I found -

etc/hosts localhost Slug52local

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts




# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
# dns-* options are implemented by the resolvconf package, if installed

This one needs no change - it is the ADSL router




syslog = 0
syslog only = yes
workgroup = WORKGROUP
server string = Slug 52 samba
security = share
encrypt passwords = yes
guest account = nobody
local master = yes
name resolve order = lmhosts hosts bcast

comment = /
path = /
browseable = yes
public = yes
writeable = yes

etc/lighttpd/lighttpd.conf - (if you need to set a differnt port than the usual 80)

## bind to port (default: 80)
server.port = 8051


ssh ftp and (even) samba now all work on !!!!

- now to see if I can get an old webcam to run.........
