HTTPS setup

Today I will talk about setting up HTTPS with Apache on a Debian system. HTTPS is used for secure connections between your web browser and the web server, minimizing the risk for hostile people to be able to listen to your communications by using standard network sniffing techniques.

This may be useful, if some of your websites handles personal data, such as a webmail application for instance.

This article supposes you already set up a basic Apache web server, as described in this previous article.

Blog engine setup

Today I will talk about how to setup a blog engine just like the blog you are reading. It uses the Dotclear PHP application.

We will also have to install and setup the PostgreSQL database system for that purpose.

Web server setup

Today we will discuss about basic Apache-based web server installation. This is a quite straightforward process on Debian systems.

I will also present the steps to setup the most commonly used Apache modules.

QEMU and KQEMU

I recently presented KVM as an efficient virtualization solution for PC's with VMX-enabled processors. Today I present another efficient solution for older processors.

QEMU is a well-known full system emulator, powerful enough to virtualize complete hardware systems. Its major drawback is that it actually emulates the processor, making it unefficient for virtualization purposes when performance is required. The KQEMU kernel module allows QEMU to use the host processor when running on a PC and emulating a PC, removing that performance barrier.

Using KVM for virtual server setup

What best way to test a server setup than to just use a brand new machine dedicated for this purpose ? Unfortunately, not everyone has a spare computer dedicated to such activities. But there is at least one solution : use a virtual machine !

The virtualization solution I have been using is KVM, one of the most efficient ones.

This article deals with the different problems system administrators may encounter when setting up such a virtual server, as well as setting up the host computer (running a flavour of Debian GNU/Linux) to let it communicate with the virtual server.

Loads of hardware (1)

I mainly describe myself as a hacker. I won't debate here about the real meaning of that term, because zillions of webpages already debate about what hackers really are. To keep things short, my definition of hackers corresponds to computer enthusiats which like to break limits of their machines and constantly work to improve their knowledge about programming and problems solving.

So, as this hobby is focused around computers, what best way to present my progress other than presenting the computers I used to spend my time on ...
