Slug – Tips

Reducing Memory Given that it has only 32MB of RAM, NSLU2 runs Asterisk as is very well, but if you want to add more daemons you might need to miser down on the memory. Dropbear Dropbear consumes only 2.4MB vs 8.2MB of SSH (who would've ever thought I'd be concerned about savings of 6MB of... Continue Reading →


De-Underclocked Slug

Following the instructions at Overclocking the Slug, I decided to overclock my NSLU2 today, and pulled out my soldering iron. It seems you're not really overclocking it... but restoring it to its normal/full speed of 266MHz. For some reason these units shipped configured to run at 133MHz, done via a pull down resistor (R83) -... Continue Reading →

First thing I did was to replace the Linksys firmware with Linux. The possibilities for use of this thing are endless: as a print server, file server,... Continue Reading →

I needed something which would consume less than 100W of power and cost less than $100. My runner ups were... Continue Reading →
