Nagios can check anything anyone is willing to write it to check. In other words if there is a way to reap results then Nagios can act on those results whether they be a set of strings, numbers or some combination therein. This two part series goes over setting up a very rudimentry MySQL status page check using common tools found on a BSD-Unix, Unix or Linux system (and it not, generally easy enough to install). This first part goes over requisites, assumptions and the status pages themselves. The second part is the Nagios end of things and of course the "other cool stuff" the creative mind can do with it all.
The single line print format for
pwutils never worked right.

pwutils collection are some very small
programs written in C, Perl, Python and Bash that do, among other things:
Should build and run on almost any Unix/Linux/BSD system.
I was thinking about doing another article about X windows when I realized not much has changed on the surface. So instead, to tide us over until I finish the current article I snagged a few old school simple window manager pictures from Xwinman.
With no lubricant! A few years ago I was involved in an effort to move
the payloads that were embedded in the Nmap code (and hence, compiled into
the executable) to a file. I learned a lot, especially that I am a lousy
C++ coder (my
work basically had to be rewritten from scratch...
but it was still fun!). I did learn one thing though, Maps in C++ are
really friggin cool and if I were a C++ programmer I would probably use
them every chance I could. They kinda sorta remind me of anon hashes in
Perl ... but not exactly the same. Regardless, here is a short text on
why we did it and an overview of how it works:
Ever wanted to process your own photos so they look older (for some strange reason)? A quick down and dirty how to add some vignette and edge shading effects to images using the GNU Image Manipulation tool or GiMP. Enjoy, have fun and if you find mistakes... I might fix them!
