Debian on a NetVista N2200

While Puppy Linux has been a solid base for this web server for quite some time now, before bringing up a second NetVista N2200 unit, I was looking to move OS to something a little more familiar - a Debian-based OS. I'd found myself wishing for the ease of the deb package management and cursing the way the entire Puppy OS was copied into RAM on startup - very clever and fast, but I don't really want my precious 256Mb filled up with unused instances of /usr/bin/xeyes ...*

I wasted an entire weekend hacking PusPus, which claimed to be able get Debian Etch onto the NetVista. This claim was true, but the OS was all but unusable - any attempt to apt-get install some useful components (like ssh), or even running apt-get update was enough for a segmentation fault and complete system halt. Tweaking the PusPus Makefiles to fetch and build a Debian Lenny image resulted in exactly the same problem.

The Single Point of Truth on all things N2200 is, rather bizarrely, the comment thread at the foot of This Guy's Blog Post, but there is some great stuff there. My saviour was the replacement boot loader and OS image by der_odenwaelder (username: NetVista, password N22008363). This guy has done a sterling job in papering over the nastiest deficiencies in the NetVista's quirky hardware.

Finally I have a (relatively) up-to-date Debian build (Lenny) on my new machine, and it goes beautifully. My local APT Cache is really starting to pay dividends now, and will be even more valuable once I migrate this machine to the same platform.

Now that I can run a more "conventional" Linux OS, I'm getting excited again about the server potential of this all-but-forgotten black box. You can pick them up from eBay's Workstations category all the time for a pittance, and with a suitable RAM and CF Card injection, you've got a handy-dandy general-purpose server that you can leave switched on 24/7 while it uses less power than your broadband router.

(*) Just an example - I removed all of the XWindows stuff from the Puppy image as soon as I got it working.
