  • Version: V2.3RA5
• Connect USB printer?
• Install backuppc

• How to install Debian on NSLU2

Installation

To install, follow the howto, here are the big steps:

• Get Debian 4.0r0 firmware from http://www.slug-firmware.net/ and unzip it
• Power the NSLU2 and wait a bit (green light) before plugging it to the network if you've a DHCP, so the NSLU2 will choose itself IP 192.168.1.77, otherwise look to your DHCP server logs to find the IP attribution
• Go to the admin webpage, tab administration, login admin/admin
• Configure ALL network params if you don't have DHCP
• Go to the admin webpage, tab administration, login admin/admin, tab advanced, tab upgrade
• Upload di-nslu2.bin, start upgrade
• Wait for "upgrading ok" (5mins) -> wait for 3 bips (5-10mins)
• This is the last moment to plug an external USB mass-storage if you didn't do so yet
• Login via ssh installer@192.168.1.77 (or another IP got by DHCP...) pwd "install"
  • I did it from an xterm but exported term mode is pure console so it's better to login from a real text console otherwise the ncurses menu is a bit broken (but still usable)
• Start installation, manually load the following modules:
  • ext3-modules-2.6.18-4-ixp4xx-di
  • partman-auto
  • partman-ext3
  • scsi-core-modules-2.6.18-4-ixp4xx-di
  • usb-storage-modules-2.6.18-4-ixp4xx-di
• Whatever system you choose to partition your disk, be sure to have at least 128M of swap, I've set up 512M on my 400G drive.
• In total it took about 100 mins to complete
• If you need a console, start a second ssh connection and choose to obtain a shell
• On tasksel, I chose absolutely nothing, I prefer to take only what I need later

After first reboot

• dpkg --get-selections|wc -l
