30x Faster WP-Super Cache and Site Speed with TMPFS

I haven’t had time to post much the past year, I’m always working! So I wanted to make up for that by publishing an article on a topic that would blow your mind and be something that you could actually start using and really get some benefit out of it. This is one of those articles that the majority of web hosting companies would love to see in paperback, so they could burn it. Now ask yourself, if a webhost makes money based on how much memory, bandwidth, and data used by a customer, what would they not want their customers to do? That’s right, they do not want their customers to learn how to minimize and drastically reduce these moneymakers. They get giddy when you complain about slow-site-speed, or that it takes a long time for your site to load, because they have exactly the right answer- upgrade your memory, bandwidth, and data by purchasing a more expensive plan.

Advanced WordPress wp-config.php Tweaks

The bottom line for this article is that I want to make WordPress as fast, secure, and easy to install, run, and manage because I am using it more and more for client production sites, I will work for days in order to solve an issue so that I never have to spend time on that issue again. Time is money in this industry and that is ultimately (time) what there is to gain by tweaking WordPress.

Note: I spent no time on readability, this is primarily a read the code and figure it out article.. This is for advanced users looking for a reference or discussion and for those of you looking to advance. Feedback would be great if you make it that far..

An AskApache Plugin Upgrade to Rule them All

So my blog as been rather quiet for almost a year now, and very few updates if any have been released for my Password Protection PLugin, my Google 404 Plugin, and definately not for my AskApache CrazyCache plugin, which I will be releasing last… So for all of you who’ve helped me out by sending me suggestions and notifying me of errors and sticking with it… Just wanted to say sorry about that, and thanks for all the great ideas.. Well, I’ve been sticking with it as well believe it our not. I manage to get free days once in a while, and then its time to jam.

DNS Round Robin Configuration using Rsync over SSH

The goal is to add the HostGator server to be an exact mirror of the static.askapache.com domain, then to add that server as a 2nd A record to my DNS zone. That way half the visitors to the size will be taking up resources and bandwidth on the HostGator server instead of mine.

Round Robin A records in DNS are intended to evenly distribute queries between each host of the same name. Using some tricks straight out of a hackers toolbox we can verify if the distribution is taking place. (It is.)

Advanced .htaccess Tricks for Securing Sites

This is all new, experimental, and very very cool. It literally uses .htaccess techniques to create several virtual “locked gates” that require a specific key to unlock, in a specific order that cannot be bypassed. It uses whitelisting .htaccess tricks to specify exactly what is allowed, instead of trying to specify everything that isn’t allowed. Also, by setting specific cookies/tokens after successfully passing through a gate, we can then require the exact cookie/token from the previous gate, which stops an attacker from skipping or bypassing gates.

.htaccess Plugin Blocks Spam, Hackers, and Password Protects Blog

Well what can I say, other than this is sooo DOPE! Here is a list of the modules this plugin (version 4.7 unreleased) will automatically detect. I compiled the list myself using every module included with any default Apache installation for ALL the versions listed below, 1.3 to 2.2+

Want to know something else I’m including in this plugin? For each and every module that is detected, this plugin can then detect ALL of the modules .htaccess Directives! For instance, RewriteRule, AccessFileName, AddHandler, etc.. are each a directive belonging to a module that is allowed to be used from within .htaccess files.

Talk about sick.. these tricks have the diamond disease!

.htpasswd file Generator

.htpasswd is a flat-file used by Apache and other applications to store usernames and password for HTTP authentication. Apache .htpasswd files may contain multiple types of passwords; some may have MD5-encrypted passwords while others in the same file may have passwords encrypted with crypt(3) and/or SHA-1. Usernames are limited to 255 bytes and may not include the character :.
Htpasswd Formats
Apache Servers recognize 4 formats for representing a password hash in the text file usually named .htpasswd.

CRYPT
crypt(3) is the library function which is used to compute a password hash. Technically the name is a misnomer since it is actually a cryptographic hash function. The output of the function is not merely the hash: it is a text string which also encodes the salt and identifies the hash algorithm used. Apache uses the traditional Unix crypt function with a randomly-generated 32-bit salt (only 12 bits used) and the first 8 characters of the password. ALG_CRYPT
MD5
MD5 is one in a series of message digest algorithms designed by Professor Ronald Rivest of MIT. The 128-bit (16-byte) MD5 hashes (also termed message digests) are typically represented as a sequence of 32 hexadecimal digits. In .htpasswd files the hash is: $apr1$ + an Apache-specific algorithm using an iterated (1,000 times) MD5 digest of various combinations of a random 32-bit salt and the password. ALG_APMD5
SHA-1
The SHA hash functions are a set of cryptographic hash functions designed by the National Security Agency (NSA) and published by the NIST as a U.S. Federal Information Processing Standard. SHA-1 produces a 160-bit digest from a message with a maximum length of (264 − 1) bits. SHA-1 is the most widely employed of the SHA family. It forms part of several widely used security applications and protocols, including TLS and SSL, PGP, SSH,…
