Build your own gateway firewall

Post date: April 11, 2006, 21:04 Category: Miscellaneous Views: 4951 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.

My First Linux Server, Part 1

Post date: April 14, 2005, 22:04 Category: Miscellaneous Views: 4466 Comments
Tutorial quote: Many small businesses are turning to Linux as way to swim against the tide of rising software costs. Are you thinking about diving into Linux for your small business? From the outside, Linux can appear to be a deep ocean of strange jargon in unchartered waters. Who has the time to wade through all that to save a few clams? With Linux, it's not a sink or swim proposition.

Linux is now a lot simpler than you may think. We can provide you with the easiest, simplest, no-problem process for installing Linux on a PC. After going through this simple installation process, you will have a basic machine that you can configure into any kind of server, workstation, or office desktop. Future articles in this My First Linux Server series will help you build productive, Linux-based servers and small office workstations.

The best choices for your first Linux machine are probably the popular Red Hat Linux or SUSE Linux, primarily because both are easy to install and configure. Additionally, these companies are sound choices for the home office or small business. Both vendors have specialized in Linux for many years and offer full corporate product lines supporting your expansion.
Gentoo

Build your own Gentoo rescue LiveCD and USBStick

Post date: June 20, 2005, 04:06 Category: Miscellaneous Views: 4944 Comments
Tutorial quote: I've written this how-to after trying to find a boot medium for my home gateway machine which could be used for system rescues and even installing Gentoo. Why not use the standard Gentoo Live CD you ask? Well my gateway machine is one of those small, silent and cool running mini-itx machines (http://www.mini-itx.com) and has no CDROM or floppy drive. I needed some way of getting Gentoo on there and some way of easily rescuing it when the need arises. The good news is that these VIA mini-tix machines are USB bootable and I much preferred the idea of having a little USB drive/stick that I could push into any USB bootable machine and boot into Linux rather than having to set up a PXE networked boot environment (which is also supported).
