CGI Programming on the World Wide Web

Post date: December 12, 2005, 17:12 Category: Programming Views: 3022 Comments
Tutorial quote: The Common Gateway Interface (CGI) emerged as the first way to present dynamically generated information on the World Wide Web. CGI allows the computer to generate Web pages instantly at the user's request rather than being written by someone in advance. And at the time of this writing, it remains the only stable and well-understood method for creating such pages. Java presents problems that have not yet been solved. Other products are currently just in the announcement stage.

CGI is fun. You can get a kick out of writing scripts that perform tricks for you, and the users enjoy the spice the scripts add to your Web pages. But CGI has a serious side too: It lets the Internet offer the kind of interactive, user-driven applications that modern computer users have come to expect. CGI opens up an entire class of modern applications to the Web.

Stack Smashing Protection for Debian

Post date: June 23, 2006, 22:06 Category: Security Views: 2878 Comments
Tutorial quote: Since we last covered the use of Stack Smashing Protection (SSP) the default compiler for Debian Sid has been upgraded to include it, with no need for custom patching. Read on for a brief demonstration of how it can be used to prevent attacks.

The default C compiler for Sid, which will be used in Etch too, is GCC v4.1. This releasecontains the SSP patch which previously needed to be applied manually (we demonstrated applying this patch for GCC v3.4 a long time ago).

Since the SSP patch is included in the compiler by default it is suddenly a lot easier to start working with it.

Creating A Fully Encrypted Para-Virtualised Xen Guest System Using Debian Lenny

Post date: May 3, 2009, 10:05 Category: Miscellaneous Views: 3408 Comments
Tutorial quote: This document explains how to set up a fully encrypted para-virtualized XEN instance. In this howto, the host system is running Debian Etch, while the guest system to be installed will be using Debian Lenny. If you are concerned about your privacy, you might want to consider using hard disk encryption to protect your valuable private data from spying eyes. Usually, the easiest way would be to use your distribution's installer to set up a fully encrypted system; I think most recent Linux distributions support this. However, when you are using XEN to provide virtualization, there are situations where you might not want to encrypt your whole computer with all guest instances, but instead only encrypt one OS instance. This howto will deal with exactly this situation. It assumes that the XEN host system is already up and running.
