BKO provides gpxe images for USB sticks, CDs, and also for floppies, i.e., you can boot from a USB sticks, a CD, or a floppy.

Brutelock is an open source program that actively monitors various system logs and immediately blocks malicious IPs trying to attack your server. Brutelock not only protects against ssh attacks but also other common systems such as ftp, pop and imap. It has an extendible rules format that allows you to monitor an unlimited number of other services by simply supplying the log file and a simple regex search pattern.

This guide explains how to set up software RAID1 on an already running CentOS 5.3 system. The GRUB bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one).

This tutorial describes how to install and configure Snort intrusion detection system (IDS), ACIDBASE (Basic Analysis and Security Engine), MySQL, and Apache2 on Ubuntu 9.04 using packages from Ubuntu’s Synaptic Package Manager.

Snort will output its log files to a MySQL database which ACIDBASE will use to display in a graphical interface in web browser.

Cherokee is a very fast, flexible and easy to configure Web Server. It supports the widespread technologies nowadays: FastCGI, SCGI, PHP, CGI, TLS and SSL encrypted connections, virtual hosts, authentication, on the fly encoding, load balancing, Apache compatible log files, and much more. This tutorial shows how you can install Cherokee on a Debian Lenny server with PHP5 support (through FastCGI) and MySQL support.

This tutorial was written for the Debian Lenny distribution and supposes that the user has knowledge about what load balancing is and some basic skills of Linux, our two load balancers consist out of 2 machines that monitor each other [heartbeat], if the master stops responding the secondary one [Backup] will take the master role [Backup -> Master].

This tutorial shows how you can install Cherokee on a Fedora 11 server with PHP5 support (through FastCGI) and MySQL support.

This tutorial explains how you can install and configure APF - an interface to IPTables which lets you easily configure a full featured firewall to secure servers and workstations connected to a network. This guide describes an example installation on a server with cPanel but it's only a matter of port numbers which must be open for everything to work. APF can be used on any system.

This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.

LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache2 webserver on a Debian Lenny server with PHP5 support (mod_php) and MySQL support.

This tutorial shows how you can limit the CPU usage of a process with the tool cpulimit on Debian/Ubuntu. cpulimit is a simple program that attempts to limit the CPU usage of a process (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you don't want them to eat too much CPU. It does not act on the nice value or other scheduling priority stuff, but on the real CPU usage. Also, it is able to adapt itself to the overall system load, dynamically and quickly.

This tutorial describes how you can install Apache2 with mod_fcgid and PHP5 on Debian Lenny. mod_fcgid is a compatible alternative to the older mod_fastcgi. It lets you execute PHP scripts with the permissions of their owners instead of the Apache user.

This tutorial shows how to set up a CentOS 4.8 server that offers all services needed by ISPs and web hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig (i.e., ISPConfig runs on it out of the box).

This guide explains how to set up software RAID1 on an already running LVM system (Debian Lenny). The GRUB bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one).

This tutorial explains how to install Django on a Debian Lenny server. Django is a web framework that allows to develop Python web applications quickly with as much automation as possible. I will use it with Apache2 and mod_python in this guide.

This tutorial shows how you can sign your email messages by using DKIM (DomainKeys Identified Mail) for multiple domains. Signing email allows the recipient of a message to confirm a message originated with the sender's domain and that the message content has not been altered.

Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on a Fedora 11 server with PHP5 support (through FastCGI) and MySQL support.

This tutorial shows how you can add a splash image to your GRUB 2 boot loader on Ubuntu 9.04. Please note that you should use this tutorial only if you have upgraded your bootloader to GRUB 2 previously.

One of the things I like about Linux is the command line. I have used nautilus, gnome-commander, konqueror, kommander, dolphin and thunar to manage files in Linux and these file managers are great for what they do. But there are times when one simply wants to find a file when working on the command line without having to open a GUI application.

This tutorial shows how you can upgrade your GRUB bootloader to GRUB 2 on Ubuntu 9.04. GRUB 2 has been rewritten from scratch to clean up everything for modularity and portability.
