Rolling your own Debian packages (part 1)

Post date: January 21, 2006, 06:01 Category: Software Views: 2797 Comments
Tutorial quote: This two-part article explains how to make a Debian package of simple piece of software, presumably something you have written yourself. Although building a new package is more complex than rebuilding one or having one generated, the idea is that it is actually surprisingly simple to create basic Debian packages. In fact, if you can make software install into a temporary installation tree, you're already 90% done! This text provides a quick alternative to the more comprehensive Debian New Maintainers' Guide. Only knowledge of Makefiles and the basic Debian package tools is assumed.

The first part of this article will continue with some preliminary information about Debian packages. In the second part we walk through a concrete packaging example.

Using the 'snort' Intrusion Detection System

Post date: December 27, 2005, 15:12 Category: Security Views: 4755 Comments

Even if you are employing lots of preventative measures, such as firewalling, patching, etc., a detection system can give you an assurance that your defences truly are effective, or if not, will give you valuable information about what you need to improve.

Fortunately, there is a good set of snort packages for Debian which takes a lot of the tedious work out of building a useful Network Intrusion Detection System. Before we start on installation, we should review a few details about the networking satack that you're going to need to make sense of the alerts snort will generate. Impatient readers and those who are familiar with the TCP/IP suite of protocols may do now skip to the bit that says Stand alone snort.
