I’m trekking into the unknown - CentOS, but thats off topic. For some reason, even the latest version stuck in 1982 - vi as the default editor for cron etc. Argh! I hate vi!

Stuck trying to find text within files on Linux?

cd /directory_tree_you_want_to_search
find . -type f -exec grep -l "string to find" {} \; -print

Imagine you have a selection of domain names that point to the same site, are some of those domains specific to certain areas of your site?

Here’s how I redirect a domain name to a specific area on a site

RewriteEngine On

RewriteCond %{HTTP_HOST} ^(www\.)?cubecartexperts\.co.uk
Rewriterule ^(.*)$ http://www.i9000networks.com/landing-page/cubecart-experts/ [L]

You’ll also need the domain set in your virtualhost config like this

ServerName www.i9000networks.com
ServerAlias www.cubecartexperts.co.uk
ServerAlias cubecartexperts.co.uk

It is a much more helpful way of helping your users navigate your site.

We know they are both the same, but do the crawlers? No, they don’t. (more…)

Network File System, NFS, has been around since Noah first networked his ark.

Setting up and using NFS on Ubuntu is surprisingly easy. i9000 Networks needed a slightly revised backup solution in one of it’s sites.

Obviously you’ll need two or more servers. One I’ll refer to as the server which will host the backups and the second/subsequent servers, which are the clients, ie. the live servers that need backing up.

Here’s how I did it.

Installing VMware on Ubuntu 7.10 isn’t as easy as Ubuntu usually makes things out to be. None the less, my handy how to will sort you out. (more…)

I’ve just stumbled over a PDF scanning engine for SpamAssassin. In light of the recent PDF spam making it’s way round the internet I figured I’d give it a try.

This plug in scans the PDF pdf body and embedded images. Great, huh?

Here’s how I did it. (more…)

FuzzyOCR is a plugin for SpamAssassin that analyzes the content and properties of images to distinguish between normal mail and spam.

I’ve been running it on some mail servers for a few months now and I’m very happy with the results. (more…)
