NSLU2

NSLU2 and it's possiblities

The awesome little device from Cisco (fka Linksys) contains a ARM 133Mhz processor, consumes around 5 watt, has an 100Mb ethernet port and 2 USB ports.

Installing Debian

This tutorial is written for "Debian/NSLU2 (armel) 5.0 Stable Release" aka Lenny - http://www.slug-firmware.net/d-dls.php

A. Using the GUI based method

/Assuming the NSLU2 contains the original firmware (otherwise use the upslug2 method)/

• Connect the NSLU2 (Ethernet, Power, USB storage to port 2), turn it on.
• In advanced mode format the storagedevice (admin/admin)
• Go to Upgrade mode and choose the new firmware (di-nslu2.bin) press install and wait about 5 minutes to complete the firmware replacement. After the upgrade is completed, the nslu2 will reboot itself.

A. Using the upslug2 method

/Assuming the NSLU2 contains another firmware/

• Connect the NSLU2 (Ethernet, Power, NO storage device yet).
• Use a paperclip and hold down the reset button, turn the nslu2 on and wait till the yellow led turns orange. After that, immediately remove the paperclip. If all is well, the led will flash alternately orange and green. Now the NSLU2 is in upgrade mode.
• Use upslug2 to upload the firmware to the nslu2 (upslu2 -d <nic> -i di-nslu2.bin
• After the firmware is flashed, it wil reboot itself.

B. Let's install debian

• Turn off the NSLU2, Connect the storage device to port 2, and turn the NSLU2 on. Wait for about 5 to 15 minutes to let the debian installer startup. When is ready for action it will sound 3 beeps.
• Login to the NSLU2 using ssh [email protected] (check you DHCP server for the correct IP address) the corresponding password is install.
• The installation of debian will start automatically; During the installation you must at least install the following services:

 -  [*] ext3-modules-2.6.18-6-ixp4xx-di: EXT3 filesystem support 
 -  [*] openssh-client-udeb: Secure shell client for the Debian installer
 -  [*] partman-auto: Automatically partition storage devices (partman) 
 -  [*] partman-ext3: Add to partman support for ext3
 -  [*] usb-storage-modules-2.6.18-6-ixp4xx-di: USB storage support

You have to make some other installation options, but they should not pose any problem.

• The actual installation can take up about 4 hour (depending on the ftp location you have choosen). The actal installation took for my around 1.5 hours.
• After the installation, the kernel will be written to the NSLU2 and it will reboot itself.
• Wait after rebooting a couple of minutes until the nslu2 is ready for action. Now login using ssh with your given credentials.
• One of the first commands to use is apt-get install ntpdate and ntpdate to set the correct date/time.

Have phun with you debian installation.
