Mark Thomas

Well what can I say?

I have been a member of HantsLug for a few years now, and have been using Linux for much of this.

I mainly use Linux at work as my main desktop machine, but have to pop back to Windows when needs arise!

Currently running SuSE9.1 on the desktop, and have a few servers knocking around running RH9

oh, suppose I should mention I’m an IT Security Engineer or something. Cheers!

Locked Down Gnome

Introduction

Note: This document is barely begun: please don’t expect to read anything useful here yet…

In fact it’s now New Year’s Eve 2005 and nothing has happened here for months. I haven’t entirely forgotten this project though…

Another Note: The project of which this was part has now ceased to exist as of April 2005, so I no longer have the motivation to continue with this at the moment. I may well delete this page at some stage, unless anyone finds a use for it — if so, please add a comment to this page. [continued…]

Debian On Ra Q4

The Cobalt RaQ Cobalt_RaQ is a 1U rackmount server product line developed by Cobalt Networks, Inc. which was later purchased by Sun Microsystems featuring a modified Red Hat Linux operating system with a proprietary GUI for server management. Original RaQ systems were equipped with MIPS CPUs but later models used AMD K6-2 chips and then eventually Intel Pentium III CPUs for the final models.

The following guide has only been tested on a Cobalt RaQ4 and may not work on all machines. However it should also work on RaQ 3/XTR/550 and the [continued…]

Red Hat Certified Engineer

Linux vendor and consultant Red Hat, offer dedicate training and testing for their flavour of Linux. It is based around their commercial Enterprise Linux product family. The training can be purchased directly from RedHat or from resellers – training offered by RedHat themselves (at Guildford) and IBM (London and other places) in the UK. Along with the main Linux track, they also offer a ranger of other allied technologies.

There are a number of courses that make up the couse work, starting with one designed for people tottaly new to [continued…]

Locking down /tmp to protect against automated and “script kiddie” exploits

Introduction

The most common way systems are compromised are through web applications. An excellent example of this is phpBB. Users install phpBB on your shared web server. It works, so they leave it. 6 months later, 3 exploits that allow code execution are found in phpBB but the user on your shared web server isn’t concerned with security. You get an email from the feds telling you your server has been taking part in a DDoS.

If you’ve ever seen such an exploit, they usual create a botnet and search for other vulnerable applications on other servers and compromise [continued…]

Qemu Use Cases

This page describes some of the ways in which a QEMU virtual machine can be used.

Test Linux Upgrade

I have a laptop running Ubuntu Breezy. I’d like to have a look at what’s coming in the next release, but I don’t want to upgrade my laptop and potentially break it, and I don’t want to dedicate a whole machine to running the new release. With QEMU I can run Linux in a virtual machine and take a copy of the disk image file before performing the normal upgrade process. If the upgrade goes well – well enough [continued…]

Kernel Building

One of the scariest moments in many Linux users’ lives is the moment when they ask someone for help, and they get the reply, “You really have to/need to/should recompile your kernel to make that work.”

In this article, I hope to take some of the fear out of the process, and make it all a bit less intimidating. This article is aimed at the user who is familiar with the use (or at least the basic concepts) of file storage and the command line, but doesn’t necessarily know about compiling things from source.

What is a [continued…]

Xen

About Xen

Xen allows you to run multiple operating systems, currently Linux (2.4 and 2.6 kernels) and NetBSD, concurrently on one PC. Xen is particularly useful for systems administrators, ISPs, and ambitious/technical home users wishing to add security to their systems. Xen is notable for its very small drop in performance of the virtual machines compared to other solutions such as LinuxHints/UserModeLinux.
