FreeBSD Building a FreeBSD Build System
Post date: April 14, 2006, 20:04 Category: System Views: 24
Tutorial quote: When you finish this article, you will have an unbeatable update system. Even mergemaster will work faster. You will have an update system in which a machine update/upgrade will take less than 10 minutes.
Ubuntu Installing Windows XP/2000 in Free VMWare Player
Post date: November 27, 2005, 12:11 Category: Miscellaneous Views: 216
Tutorial quote: This guide will allow you to install Windows XP or 2000 solely with the VMWare Player. For the uninitiated, VMWare released a free application that allows users to run, but not create virtual machines. Using QEMU, we will create an environment suitable for use with the player.

As a side-note, I'd like to point out that VMWare makes quality software. If you require additional functionality, consider upgrading to Workstation.
Gentoo Remote Backup Using Flexbackup and SSH
Post date: December 31, 2005, 10:12 Category: Network Views: 97
Tutorial quote: I have a server running Gentoo Linux which hosts a Subversion repository, a vpopmail and qmail system, a MySql database and more. I’m going to make a backup copy of the data on this machine in the event that I need to rebuild this server. I have chosen Flexbackup to perform this task.
Debian Manipulating the windows upon your desktop
Post date: January 19, 2006, 08:01 Category: Desktop Views: 79
Tutorial quote: If you're like me you'll most likely use a wide variety of desktop applications, and spend a lot of time setting up your desktop first thing in the afternoon when you login. Minimising some applications, setting others up to be visible upon all virtual desktops, etc. Even if you have a basic window manager you can automate this activity using Devil's Pie.

Devil's Pie is a simple utility, inspired by the Sawfish's matched windows option, which allows you to conduct actions upon desktop windows. Using it is a simple matter of creating a configuration file and starting the program when you login.
Debian Debian Kernel Compile Howto (Kernel 2.6)
Post date: April 12, 2005, 14:04 Category: System Views: 93
Tutorial quote: In some cases you might want to compile your own kernel that suits your needs better than the standard kernel that comes with your distribution. I will describe how to do this on a Debian machine. Please note that this tutorial is for kernel 2.6 only!
Debian dmcrypt
Post date: January 25, 2006, 17:01 Category: Security Views: 85
Tutorial quote: Device-mapper is a new infrastructure in the Linux 2.6 kernel that provides a generic way to create virtual layers of block devices that can do different things on top of real block devices like striping, concatenation, mirroring, snapshotting, etc... The device-mapper is used by the LVM2 and EVMS 2.x tools. dm-crypt is such a device-mapper target that provides transparent encryption of block devices using the new Linux 2.6 cryptoapi. Writes to this device will be encrypted and reads decrypted. You can mount your filesystem on it as usual. But without the key you can't access your data. It does basically the same as cryptoloop only that it's a much cleaner code and better suits the need of a block device and has a more flexible configuration interface. The on-disk format is also compatible.
Fedora+Core The IPv6 Internet: Connect Today with Linux
Post date: April 12, 2005, 23:04 Category: Network Views: 86
Tutorial quote: IPv6 is a key technology and a long-term solution to build scalable, reliable, manageable, secure, and high-performance IP networks. In this article, I demonstrated how to configure a Linux machine running Fedora Core 1 to support IPv6 and connect it to the IPv6 Internet using the Freenet6 service.
Debian Splitting updatedb into daily and weekly
Post date: April 21, 2006, 08:04 Category: System Views: 14
Tutorial quote: We all appreciate the locate command when we are such in a hurry we cannot afford a full and in-elegant find. What we like a little less, though, is the updatedb script consuming up all our disk bandwidth at each boot, summoned by anacron.

Of course, this is only the case if you are running a "desktop" machine: since you turn it on when you need to do some work, then you long for a way to shorten the period of reduced usability forced by updatedb.

Inversely, if you run a server that never goes down, and you successfully schedule your updatedb tasks late at night, then this article is not for you.
FreeBSD FreeBSD Working Document for Installation, Setup
Post date: May 8, 2005, 17:05 Category: Miscellaneous Views: 135
Tutorial quote: This is a working document that we use to set up and maintain FreeBSD. We hope you find it useful, and that it encourages more use of FreeBSD in general. The first section of the document is a series of steps we take during initial installation to produce a useful machine, from our perspective of course. The second section lists commands related to specific applications or situations.
FreeBSD Configuring virtual domains with Cyrus+Postfix in FreeBSD 5.4
Post date: November 30, 2005, 22:11 Category: Software Views: 153
Tutorial quote: Cyrus IMAP is an efficient IMAP server capable of handling a large number of accounts. Its biggest drawback is getting it installed and configured. This tutorial is a step-by-step guide on how to use Cyrus with the Postfix mail transfer agent (MTA). I tested these instructions with FreeBSD 5.4.

Postfix is a replacement for sendmail, the stock MTA that comes in FreeBSD. It is easier to configure and manage than sendmail. If you depend on sendmail, you can still look at the article for the Cyrus part, but you'll need to look elsewhere for the MTA configuration.

Unless otherwise instructed, perform all operations in this tutorial as root. You will need to use the port system. If you are new to it, check Chapter 4 of the FreeBSD Handbook.
