An AskApache Plugin Upgrade to Rule them All

Post by AskApache Jul 29, 20091 comment

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

Post by AskApache Apr 14, 20096 comments

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.)

AskApache Debug Viewer Plugin for WordPress

Post by AskApache Apr 05, 20091 comment

The story behind this plugin is sorta wack, but in a good way :). While doing tons of security research on permissions, authorization, access, etc.. for the Password Protection plugin (still being worked on), I needed to have unheard of debugging capabilities while working on the plugin on the various websites, webhosts, and test servers that I use to test in different environments. So I hacked together a bunch of php code that helped me debug, actually I pretty much went overkill and tried to get as much debugging info as programmatically possible, and it ended up being so much code that I took it out of my Password Protection code and made it its own plugin.

THE Ultimate Htaccess

Post by AskApache Jan 10, 200988 comments

Skip this - still under edit

I discovered these tips and tricks mostly while working as a network security penetration specialist hired to find security holes in web hosting environments. Shared hosting is the most common and cheapest form of web-hosting where multiple customers are placed on a single machine and "share" the resources (CPU/RAM/SPACE). The machines are configured to basically ONLY do HTTP and FTP. No shells or any interactive logins, no ssh, just FTP access. That is when I started examining htaccess files in great detail and learned about the incredible untapped power of htaccess. For 99% of the worlds best Apache admins, they don't use .htaccess much, if AT ALL. It's much easier, safer, and faster to configure Apache using the httpd.conf file instead. However, this file is almost never readable on shared-hosts, and I've never seen it writable. So the only avenue left for those on shared-hosting was and is the .htaccess file, and holy freaking fiber-optics.. it's almost as powerful as httpd.conf itself!

Most all .htaccess code works in the httpd.conf file, but not all httpd.conf code works in .htaccess files, around 50%. So all the best Apache admins and programmers never used .htaccess files. There was no incentive for those with access to httpd.conf to use htaccess, and the gap grew. It's common to see "computer gurus" on forums and mailing lists rail against all uses and users of .htaccess files, smugly announcing the well known problems with .htaccess files compared with httpd.conf - I wonder if these "gurus" know the history of the htaccess file, like it's use in the earliest versions of the HTTP Server- NCSA's HTTPd, which BTW, became known as Apache HTTP. So you could easily say that htaccess files predates Apache itself.

Once I discovered what .htaccess files could do towards helping me enumerate and exploit security vulnerabilities even on big shared-hosts I focused all my research into .htaccess files, meaning I was reading the venerable Apache HTTP Source code 24/7! I compiled every released version of the Apache Web Server, ever, even NCSA's, and focused on enumerating the most powerful htaccess directives. Good times! Because my focus was on protocol/file/network vulnerabilites instead of web dev I built up a nice toolbox of htaccess tricks to do unusual things. When I switched over to webdev in 2005 I started using htaccess for websites, not research. I documented most of my favorites and rewrote the htaccess guide for webdevelopers. After some great encouragement on various forums and nets I decided to start a blog to share my work with everyone, AskApache.com was registered, I published my guide, and it was quickly plagiarized and scraped all over the net. Information is freedom, and freedom is information, so this blog has the least restrictive copyright for you. Feel free to modify, copy, republish, sell, or use anything on this site ;)

Serve External Javascript Files locally for Increased Speed

Post by AskApache Oct 01, 20085 comments

One way I speed up AskApache.com is by downloading external third-party javascript files to host on my own server instead of externally. In addition to the obvious speed boost, this lets you configure the caching and compression settings for the files.

COMPUTER SECURITY TOOLBOX

Post by AskApache Sep 26, 20083 comments

List of mainly obscure security software geared more for the master pentester. These are mostly for unix, bsd, and mac and many are difficult to install and setup (require custom servers, inside access points, obscure libraries). Only programs that output data are included, so no actual exploits or anything. Most of these output extremely useful albeit extremely technical information.

Encrypted WordPress / phpBB Backups

Post by AskApache Aug 04, 20083 comments

Enter your DOMAIN_ROOT and the location of your wp-config.php or config.php, and this script finds all the mysql settings by parsing the phpbb or wordpress config file, then creates GPG encrypted backups, and saves your settings for future automation.

Automated Folder Backup Shell-Script

Post by AskApache Jun 12, 20081 comment

This simple unix shell script automatically creates backups of a specific folder at regular hourly, nightly, weekly, and monthly intervals. Instead of the usual method for copying directory trees using tar with fifo, pipes, rsync, or NFS methods this script uses cpio which is much much faster and has cool options like saving m/a/c times, symlinks, relative paths, and weird file names.
