How to forward/archive all email for a user
May 3rd
Today I am going to show you something pretty nifty: how to forward a copy of all incoming and outgoing mail for a particular email user. If you are the cautious type, or simply the email hoarding type like myself , this can be really handy for easy archival of all your mail. Exim can be configured so that your server will automatically (and quietly) send a copy of every message you send and receive over to another email address. This is all done without you noticing anything extra in the ‘To’ or ‘CC’ fields. Silent and effective.

Change a document root on cPanel
Mar 30th
What is the document root?
When you visit a web site, you are accessing a particular folder on the web server. The server knows to only serve up those files located at that folder to incoming visitors. The location of that web folder is called the “Document Root”.
It is similar to using a coat check. You present your ticket to the attendant and they fetch it from the back room. In this metaphor, the coat is the site you want to visit and the attendant is the web server. The visitor doesn’t know the exact location where the coat is More >
How to install PHP memcache
Feb 28th
This guide will help you install PHP Memcache on a CentOS server.
What is PHP memcache?In my previous article, I showed you how to install Memcached, the service daemon. Now, if you would like your PHP software to interface with that daemon, you will want to install a PHP extension for it.
There are actually two separate implementations of a PHP Client that wraps the memcached (daemon); both are provided via the PECL library. One is called ‘memcache’ and the other is called ‘memcached’. I know that it is a little confusing that ‘memcached’ shares the same name as the daemon itself, More >

# Updates # 02/22/12 – Updated RPM locations
This guide will help you setup Memcached on a CentOS server.
What is cachingBefore diving into Memcache specifically, let’s take a step back. What is caching? Why should you care and why should you use it? Caching is used for two very important reasons: to speed up the delivery of the pages and to alleviate system resources. Caching is used to speed up dynamic sites; database driven sites will benefit most form caching. Think about a WordPress site. Each page you visit is not an actually file, but rather an amalgamation of the More >
Spoofed Bingbot attacks against WP
Feb 2nd
# Updates # 02/04/12 – Revised wording to reinforce Bing’s perspective # 02/02/12 – Modified block code to identify bingbot as ‘badbingbot’ in case ‘bingbot’ is already being used somewhere
In the last 24 hours, I have seen a large scale attack on the admin logins for thousands of WordPress sites. The attackers are using the User Agent ‘Bingbot’. Bingbot certainly is NOT the culprit in these attacks, but is, unfortunately, being spoofed. These spoofing bots are attacking the wp-admin page. So far, I have only seen this affect WP Mage and Mage Monster users.

Auto fix for file permissions and ownership
Oct 22nd
# Updates: # 05/10/12 | Bug fix for file names that contain special characters. # 01/26/12 | New feature rich script written by Colin R.
suPHP and FastCGI require files and folders to have a specific set of permissions/ownership from other handlers. Without these permissions set you will see a lot of errors such as: “403 Forbidden”, “500 Internal Server Error”, or simply generic errors that commonly have the word ‘permission’ in them.
It can be very time consuming to track down and check file permissions across a whole server. Luckily, fixing this on a cPanel box can be scripted. This gives More >
