nslu2 installation

I need to change the HDD of my Linksys NSLU2 so I will use the opportunity to write a small HowTo to show how to set up an unslung firmware into my nslu2. Let’s start

First of all I need to download the last version of Unslung firmware and install in my ubuntu box the software to put the firmware into my nslu2:

sudo aptitude install upslug2

I put my nslu2 into upgrade mode and …

# upslug2
 [no NSLU2 machines found in upgrade mode]

What happen? I always forget I have two network cards (eth0 and eth1) and I use eth1

upslug2 -help
upslug2: usage: upslug2 {options}
-d --device[eth0]: local ethernet device to use
-t --target: NSLU2 to upgrade (MAC address)
-i --image: complete flash image to use

so …

sudo upslug2 -d eth1 -t  00:13:10:d9:03:ff -i Unslung-6.10-beta.bin

network is a my home network is a so I need to change my IP if I want to connect to my nslu2:

sudo ifconfig eth1 netmask up

Now I open a browser and type

From the web interface I change the ip from to, the gateway and the dns.

change again my IP

sudo ifconfig eth1 netmask up

and open again a browser

Now I format plug the HDD to the device (into Disk1) and format it from the web inteface.

Now I enable telnet, telnet to the device with the default username/password (root/uNSLUng) and unsling disk1
