Clamassassin

For those who want an easy to setup anti virus I highly recommend the use of clamassasin combined with ClamAV and Procmail.

First you’ll need to setup your MTA and Procmail as usual, then get clamassassin from [http://drivel.com/clamassassin/].

Download the package supplied and extract it, and follow the README file.

formail is part of Procmail remember, not a separate package. Also mktemp is most likely already on your system [1], to test try it on the command line, if you don’t get a command not found error then you should be OK.

Key Signing

I'm not going to discuss here how to handle the simple mechanics of getting PGP (or GnuPG) to manage keys. Neither am I going to go through the basics of public key cryptography. I'll leave that for others to do, and assume here that you know about both of those. (If you want to know more about setting up GPG and how it works, try the mini-howto. Instead, I want to describe the steps that people normally go through to sign someone else's key, and why all of those steps should be done.

Fighting Spam

Fighting spam

Introduction

This page describes some ways in which you can help fight spam or at least reduce the amount of spam you receive in your Inbox. It doesn’t go in to any detail on how to install or setup spamd or spamc for example or how to use the SpamAssassin configuration in a “global” sense (although it’s possible to do).

Some of the configuration file locations may be distribution specific. Some of the configuration options may not work for your release of Linux distribution/release XYZ.

Please add your own details to this page [continued…]

Lspci Output

The output of lspci -n is pretty cryptic. If you want to know what all the numbers mean, read on…

Small Hosting

I’m looking for 1U, possibly 2U, of hosting (initially; may well be more later) somewhere between Reading and Bristol. No huge bandwidth requirement, but I must be able to get physical access if needed, and of course good availability. — KeithEdmunds

UK Hosting

Things to consider about moving out of London:

  • The datacentres outside London are more often based on one ISP’s transit, i.e. the same company that provides you IP transit also owns the facility and this is the only company you can use for IP transit. That means you can’t shop around for [continued…]

Disks And Partitions

(NOTE: This is a work in progress. Don’t add it to the index pages)

Disk partitioning in Linux can be confusing. This article attempts to take some of the mystery out of it.

Disk controllers and disks

The first thing to know about is the naming of disks. Linux’s approach to disk naming is slightly confusing, and requires a little knowledge about the hardware.

Linux treats different types of disk hardware differently. Concentrating on commodity PC hardware, there are four or five main types of storage hardware available:

Pseudo Root

Introduction

This document outlines some of the things that you can do to make your life easier when needing to perform tasks as user root while still logged in as your normal self. Doubtless many people are su’ing to root to perform tasks. That’s fine for single commands, but there are other means, which this article will look at. You may well be wondering why not just log in as user “root” all the time. The answer is simple. Unless one never makes a mistake in typing, and trusts everything running won’t ever damage one’s computer, then go [continued…]

Customising Fluxbox

Customising (and using) fluxbox

Introduction

Fluxbox is a Window Manager, just like KDE, GNOME, XFCE4 etc. At first, fluxbox looks very basic but with a few tweaks, it’s a very nice window manager and extremely fast. I once thought XFCE4 was fast…

This guide will go through some of the things I’ve done with my fluxbox install.

Very quick introducing to using fluxbox

To get it running, simply put exec fluxbox in your .xsession file and run startx

You’ll notice fluxbox is very minimal (and fast!). If you right click anywhere on your desktop it’ll [continued…]

Setting Up Wiki

There are numerous choices of wiki software. MediaWiki is the software used to power Wikipedia, which is very powerful and scalable, but the familiarity of the software tends to push users towards treating the wiki like an encyclopaedia. This may or may not be what you want.

Closer to the classical WikiWikiWeb, MoinMoin is very popular especially among open-source documentation wikis.

This website used to run UseModWiki, which is a simple Perl wiki script. UseMod lacks many of the features provided by other wikis, and has received bugfixes only [continued…]
