We wrote about keylogging in this article, and used gcc and Linux to intercept and decode a key push via the parallel port. We have also written in the past about various homebrew projects where a limited development system would be very useful. The perfect platform for many of these projects is discarded PCs that […]
Using uClibc For Control Systems
Bringing Up a uClibc System
We wrote abut uClibc in this article. In this article we will build an entire Linux system using uClibc that has gcc, system utilities, a 2.4.20 kernel, and uses less than 63 megs total for the entire system. The intent is for us to write homebrew articles on a stable system that can run with […]
Moving a uClibc System to Zip
In this article, we built up a uClibc system. In this article, we will transfer the filesystem to a 100 meg zip disk. What this means is that if you have an old parallel port zip drive laying around, you can bring up a development system running Linux without touching your hard drive. There are […]
GIAGD: More Fun / Introduction
There is a new section on NetAdminTools, now, called GIAGD. In this section we will configure a system based on uClibc. Now, we aren’t planning on updating the system beyond what is needed, so we will probably be staying with the uClibc root filesystem as of March 01, 2003. There are newer versions out there, […]
Startup Scripts for Housey
Housey is hooked up to the 8048 dev system. Housey wasn’t very smart at startup, so I added some init scripts. uClibc uses System V init, which means (among other things) that S scripts in /etc/init.d are executed in ASCII order. So, S10 runs before S20. I put two scripts in /etc/init.d. In S40net I […]
Creating Filesystems On Hdc
The default uClibc install doesn’t have hdc devices. You can’t make an ext3 filesystem or use fdisk either, for that matter. The first task is to create the hdc devices using mknod: mknod hdc b 22 0 mknod hdc1 b 22 1 mknod hdc2 b 22 2 mknod hdc3 b 22 3 Not too painful. […]
