Tools Logo

In the course of my work, I've developed a very large set of tools that I use for network security or for general system administration. For some of them I've managed to package them up with proper documentation such that they can be released, and this is the home page for them.

Packaging up these tools is a fair effort, and I'll try to get to them as quickly as I can. Be patient.

Unless otherwise mentioned, all these tools are in the public domain: I claim no copyright on them. Take them, use them in your own products, sell them, claim it as your own: whatever. This is free software. But feel free to say thanks :-)
