dmcrypt

Post date: January 25, 2006, 22:01 Category: Security Views: 4354 Comments
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.

Installing Xen 3.0 upon Debian Unstable, with a custom Kernel

Post date: December 29, 2005, 07:12 Category: System Views: 3551 Comments
Tutorial quote: Recently we demonstrated the process of installing a binary release of Xen 3.0 on Sarge, since the packages on Debian Unstable are not yet available for Xen 3.0 we're now going to look at installing it via the packages provided by Ralph Passgang. This also includes building a custom Xen kernel from source.

The advantage to building the Xen kernel from source is that you can add, or remove, drivers - so the kernel is utterly customised for your system.

How to set up a home web server

Post date: September 21, 2006, 21:09 Category: Network Views: 9389 Comments
Tutorial quote: It seems like everybody's blogging and sharing digital photos online. This booming hobby (and business) sends many people to paid hosting companies to share their thoughts and images. Though many companies are reliable and inexpensive, with a little work and some relatively cheap hardware you can host your own files, save some money, and have complete control over what services are available and how your content is displayed.

Building a Linux cluster on a budget

Post date: November 18, 2005, 19:11 Category: Network Views: 4009 Comments
Tutorial quote: So you need a lot of computing power but don't want to spend tens of thousands of dollars on a commercial cluster? Or maybe you just have a lot of machines sitting idle that you would like to put to good use? You can build a powerful and scalable Linux cluster using only free software and off-the-shelf components. Here's how.

SSH: Best Practices

Post date: January 17, 2008, 13:01 Category: Security Views: 4572 Comments
Tutorial quote: Are you using SSH in the best way possible? Have you configured it to be as limited and secure as possible? The goal of this document is to kick in the new year with some best practices for SSH: why you should use them, how to set them up, and how to verify that they are in place. All of the examples below assume that you are using EnGarde Secure Linux but any modern Linux distribution will do just fine since, as far as I know, everybody ships OpenSSH.

Automated distributed backups for laptops

Post date: February 14, 2006, 21:02 Category: Network Views: 2608 Comments
Tutorial quote: This document will describe the setup I made for automating the backup tasks for all laptops here in the house. My servers use the same backup server and infrastructure, but right now they don't have the checks and scripts because they are online 24/7 and my backup server is triggering the backup process. This is however not true at all for the laptops.

Laptops can be at different places, powered down, suspended, put to sleep etc. So I needed a different approach for them.

Build your own gateway firewall

Post date: April 11, 2006, 21:04 Category: Miscellaneous Views: 4982 Comments
Tutorial quote: Learn how to build your own gateway firewall using FreeBSD and old PC parts. The firewall will consist of the PF firewall, Snort IDS, various IPS applications, Squid proxy, and some intuitive web interfaces for auditing. The cost of this project should be between free and $200 depending on your resourcefulness. I built mine for free using spare parts that were stockpiled in personal storage and parts that the USMC was throwing away, but you can build one from used and/or new parts for dirt cheap.
