This tutorial is about configuring a router on FreeBSD operating system using IPFIREWALL (ipfw).

This tutorial is for creating a production Web Server using FreeBSD. You have detalied instruction what packets to install in order to have a production web server with php, mysql and support for all kind of CMS, Blogs, or other php scripts.

If you want to create a Mail Server with Virtual Users using Postfix, MySQL, SSL, IMAP and POP3 this is all you need. Tutorial was created for FreeBSD but the configuration is the same on Linux.

The ubiquitous Linux, Apache, MySQL, and PHP/Perl/Python (LAMP) combination powers many interactive Web sites and projects. It's not at all unusual for demand to exceed the capacity of a single LAMP-powered server over time. You can take load off by moving your database to a second server, but when demand exceeds a two-server solution, it's time to think cluster. LAMP cluster is not the Beowulf kind of cluster that uses specialized message-passing software to tackle a computation-intensive task. It does not cover high availability features, such as automatic failover. Rather, it is a load-sharing cluster that distributes Web requests among multiple Web and database servers while appearing to be a single server

In case you don’t already know, NDISWrapper is a tool for Linux that allows the use of Windows drivers. This is almost always used for wireless network drivers. It is a very simple way of setting up a previously unsupported device in Linux. This article will describe the setup of NDISWrapper and the installation of the wireless network device driver.

SSH is similar to telnet in that its main purpose is remote admin access to a system. They have a few differences, one being that SSH uses port 22 opposed to 23 like telnet. Basically, having an SSH connection to a Linux box is nice because it allows you to control the shell as if you were sitting in front of it and from anywhere in the world. This can be beneficial to a server machine, in general, because it allows you to install updates, tweak settings, and carry out administrative tasks. An example being, changing the home directory of an FTP user.

An updated guide covering the emulation of Linux in a windows OS. Covers many differetent distrobutions and scenarios.

NDISWrapper is a tool that allows the use of Windows wireless drivers in Linux. Most distrobutions support NDISWrapper and SUSE is no exception. In fact, it is shipped with SUSE. This is good because there is no need to find a source to the internet in order to download the necessary files. I will be using SUSE version 10.0 (the opensource/free version), but the setup is almost identical in 9.3.

Let me first start off by saying this is not really a how-to document. It is more of a what I did document. Obviously this won't work for everyone, but it might give you a good idea about what you can do with DNS. I am writing this for myself and will share it because you might learn something. If I skip over something that you don't understand, I am sorry. If you need help or have questions about this article, go ahead and create a post in the appropriate forum.

An easy way to run and learn Linux without ever leaving your Windows Desktop.

This section is about getting Linux and Windows to work together, either in the same network or even on the same machine. It also talks about things you can do to help yourself (and others) ugrade from Windows to Linux.

"I was going to go off on a cute riff about "Lilo and Stitch," but after enduring a rant from a friend about how the movie had NOTHING to do with bootloaders, I reckon I'll just stick to the point. Darned over-literal geeks anyway. "If you're still lumbering along with the antique Linux Loader LILO, you really ought to consider migrating to GRUB, the Grand Unified Bootloader. LILO is quite good, and, as the saying goes, if it ain't broke... But GRUB has some advantages that make it, in my opinion, the Bootloader of today's generation.

If you are a Linux administrator, scripting can make your life easier by allowing you to automate routine tasks, customize jobs, and connect different utilities. This article looks at Bash, the default command shell on most Linux distributions.

Businesses everywhere need to use spreadsheets, at some point or another. Depending on the business and industry, spreadsheets can be anything from very simple lists used for sorting to kazillion cell monsters that add, multiply, and figure up gravitational forces throughout the entire universe. And we all want pretty charts so we can estimate budgets and show off our stellar company performance.

Email and instant messages shoot back and forth between people these days. Unglamorous, plain old boring business documents, however, remain the stalwart of legally binding communication in the business world. It's changing, but many fields still require printed and/or signed material for day to day operations. Business letters, reports and brochures all need to be produced quickly and efficiently.
