Mass-Moving cPanel Accounts 2007-10-22 10:32:50 If you’ve ever needed to move a ton of cPanel
accounts from one server to another, you probably know the following:
The multiple account move feature in WHM fails miserably
It takes forever to do them one by one, esp. when you have other things to do
I figure the best way to mass-move accounts is by listing all the accounts in a file, then using a simple bash script to repetitively package all the accounts to they can be moved to another server.
First, you need to create a file (like users.txt) to list all the users you wish to move. If you’re only doing a few you can just go ahead and list the users in there manually, but if you’re doing like a whole server, you can get all the users in one file like so:
ls /var/cpanel/users > users.txt
You’ll then need to manually edit the users file and remove the ‘.’ and ”..’ entries, and any others that should not be included. The users.txt file should also be in a format like this:
user1

Halloween…Sucks 2007-11-01 09:12:17 This is probably the first Halloween
that was a complete disaster. First, I dropped almost a couple hundred on this custom-made Greek [hoochie] goddess outfit. But the lady made the dress too short, kind of to the length of a t-shirt&hellip
;she also made it one size too small which was Ok, but it only accentuated the fact that the dress was so short that half of Hampton Roads would have seen my ass. When I called the lady up she was like ” Just wear panty hose, no one will notice” but yea, like sheer stocking are going to hide anything.
So after my sister forbid me to wear it, I opted to wear this French maid costume that I bought last year and never wore. Problem with this one is that I dropped a few pounds over the last year, which in turn caused the costume to drop off of me. I had to use like 30 safety pins to permanently attach the thing to the corset underneath which was uncomfortable as hell. At lease Capone’s outfit fit him, he just went as Hugh H
How to Make Your System Admin Mad by Creating Huge-Ass Files 2007-10-31 08:43:00 So If you’ve ever woke up in the morning and asked yourself…”Hmm, how can I make my system admin’s job harder to the point where they get mad and shut down my server?” Well, lucky for you I can answer that question. All you have to do is use the ‘dd‘ command to write a 120gb file to an 80gb hard drive. That’s a winner.
By ‘dd’ I’m not talking about my bra size, people. It’s sad, but we recently had an over-curious customer try to see what would happen if the hard drive filled up on his dedicated server. You know what happens when you flush a clogged toilet? Yea….
So here’s the command:
dd if=/dev/zero of=test bs=1024 count=125829120
This command will write a 120gb file directly to the disk. ‘of’ specifies the name of the output file, while ‘bs’ represents the size of a block and ‘count’ is how many blocks to create. Really, it’s a dangerous thing to Read more:Admin

Selling Ad Space 2007-11-04 08:02:28 Those of you who read Corgie’s post on the front page of Digg the other day, the answer is no — I’m not selling ad space (or sponsored reviews) on my site at this time, and obviously not for $560 a month. I might in the future when I get more traffic but when that time comes the announcement will be made by me, not some idiot who eats roaches for a living. In case you’re wondering why:
At the time of this writing, my monthly traffic totals about 756,000 hits per month and 20,000 per day (give or take a few thousand), only a fraction of which are unique, reflected by the stats counter on the right-hand side of my site. Corgie claimed that I get millions of hits of day, making it look like $560 is a fair price to pay. The reality is, most of the sites that I link to already only get 30-100 hits per month from my site, which is probably only worth $2 per month.
My site is a personal site mainly focused around programming and the worthless stuff I choose Read more:Space
Sploggers Don’t Deserve to Get Laid 2007-11-15 11:12:25 Have you ever read an article somewhere and realized that it looks too familiar? That’s because you probably wrote it a year or so ago, or read it on someone else’s blog. “Splogs” are usually fake (and some legitimate sites) blogs that harvest your blog’s content via script, then mirror it on their own sites in order to boost pagerank and ad revenue.
Honestly I was unfamiliar with this term until a few months ago when I started getting emails about my posts ending up in various places on the Internet. Some people were accusing me of stealing, others were just looking out for a fellow blogger and letting me know that my boobs weren’t the only thing going around the web. I think the act of someone’s website being duplicated around the Internet is like web herpes — it spreads around and you can find it all you want, but there’s no stopping it.
When it comes time that you find one of your posts lingering on an unfamiliar websit
Installing Mod_Python 2007-11-11 02:46:28 I figured I’d put this out here because it’s come up quite recently with people who are using Apache 1.3.x. If you haven’t gotten the balls to upgrade to Apache 2.x yet, you can still install mod_python…just not as easily. This simple walk through is for Apache 1.x and 2.x.
First, you need to determine what version of Python
you are running. To check, type ‘python -V‘ at the command line. If you are running Apache 1.3.x, you should use mod_python version 2.7.11. For Apache 2.2.x, use 3.3.1.
1. Download the Python sources for the version of Python that you have installed, the run a configure and make (no install) just to compile them. If you are running Apache 1.3, you should add –without-threads to your configure line.
2. Once you have this, follow these steps to compile mod_python:
cd /usr/src
wget http://www.trieuvan.com/apache/httpd/modpython/mod_python-2.7.11.tgz
tar -xvzf mod_python-2.7.11.tgz
cd mod_python-2.7.11
./configure &ndas
A Simple Way to Save Bandwidth in PHP 2007-11-18 08:05:40 If you were ever looking for a quick and sexy way to save bandwidth on your PHP-based porn high traffic site, all you have to do is add these two lines to the beginning of your PHP scripts:
<?php
@ini_set(’zlib.output_compression_level’, 1);
@ob_start(’ob_gzhandler’);
?>
This will automatically tell the server to compress the PHP page before sending it to the browser. However, sometimes this can causes excess load and a decrease in the speed of your website, but it’s hardly noticable. Read more:Bandwidth

One thing I should mention from personal experience is that the Migration Assistance really sucks sometimes. When I first installed Ubuntu it was quick and painless, but upon a re-install on a dual boot machine the installer would infinitely stick on the account migration. If this happens to you, you’ll need to reboot from the CD, log into the terminal, then run the installer without the Migration Assistant:

Installing IonCube loader with Zend Optimizer 2007-11-18 07:48:15 This is a common request we get for Ioncube to be installed. It’s generally not an issue, but when you factor in other optimization plugins like Zend and eAccelerator, a common misconception is that the three don’t get along. It’s very easy to install Ioncube into a PHP installation that already has Zend and eAccelerator.
This tutorial is specific to cPanel, assuming that you are using php 5.2.x with Zend 3.x.x.
If you need help installing eAccelerator, you can see this tutorial. For help with installing Zend, you can go here. The versions in both these tutorials are outdated, so you’ll probably want to apply the instructions to the newest versions available.
Go to http://www.ioncube.com/loader_download.php and pick your download. This example assumes that you are using php 5.2.

How to Commit Genocide on Annoying Processes 2007-11-21 20:20:40 A few days ago I came across some processes on one of our servers that just wouldn’t die. Even after doing a kill -9 and all that good stuff, more would just keep spawing until there were dozens running on the machine. A head system admin of ours gave me this command, which will mass-kill all alike processes so they don’t have a chance to re-spawn each other.
The processes running were all some form of “init_”, like init_1, init_13, etc. To kill these:
ps aux |grep init_ |awk ‘{print $2}’ |awk ‘{print “kill -9 ” $1}’ | sh -v
The ‘grep init_’ should reflect the common name of all the processes. Read more:Annoying

Massive Upgrade Time 2007-12-01 21:33:52 I decided to stop being lazy and get around to those upgrades I needed for my site and server:
- Upgrade PHP to 5.2.5 and Apache 2.2.6 (was running 5.2.3 and 2.2.4)
- Upgrade Gallery2 and the WPG2 plugin for Wordpress
- Upgrade Wordpress to 2.3.1
First, I should admit that I do use the EasyApache installer from WHM, as it has vastly improved to the point where I don’t have to troubleshoot its builds afterwards, nor do I have to go back and reinstall eAccelerator and Suhosin - The current release of cPanel now includes those options and I must say that they have become rather flawless. In other words, it saves me the time of compiling shit by hand when all I have to do is click a few buttons and all the hard work is done for me.
Second, I was avoiding the Gallery2/WPG2 upgrade because I remember that the first time I set it up it was hell, and since it was so long ago I didn’t want to go through that again.
Third, since my last Wordpress upgrade I had numerous problems wi
MX Validation in PHP 2007-11-30 23:16:38 Hosting companies have all kinds of tactics to keep spam away from their customers, but one very common complaint I get is the amount of spam coming in through contact forms. Even though we don’t allow ‘nobody’ mail through the php mail() function and we provide the best server-side spam filters available, local mail cannot be filtered or limited. In other words, no spam filter in the world is going to save you from your shitty contact form.
I started recommending to our customers to implement MX checks in their forms as spam bots nowadays can easily get past things like captcha and textual confirmations. Spammers rarely send email from valid mail hosts so it’s very easy to filter these out with just a few lines of code:
<?php
list($user, $domain) = split(“@”, $email);
if (checkdnsrr($domain, “MX”)) {
} else {
}
?>
To explain the code a little bit, you’re basically taking your stored email address variable ($email) and using the split() Read more:Validation
GRUB Errors on Windows Dual Boot 2007-11-30 21:24:15 I don’t want to admit that I still have PC’s that dual boot Windows
XP and Vista, but given the occasional problems I have after Ubuntu and Fedora updates I’m not ready to give them up yet. Some time in the middle of the night last night my laptop, which used to dual boot Ubuntu and Vista (before I deleted the Ubuntu partition), rebooted and left me with a ginormous GRUB loader error:
GRUB Loading stage 1.5
GRUB loading, please wait...
Error 15
The issue is that the boot loader probably went apeshit and doesn’t know what to do. Since Windows is the MBR nazi, it’s best to use Windows to fix it.
Luckily with all the luck I’ve had with Vista I still had the install CD and was able to recover quickly. For those of you at home, if you don’t have the original install CD you need to create a boot disk and slide it in <insert giggle here>. From the CD, when the menu comes up hit ‘R’ for recovery console which will bring you into Read more:Errors
How to Upgrade to a Non-Existent MySQL Version 2007-11-28 21:22:05 Working in webhosting for a while now I’ve had some people ask for really weird shit, and I’ve dealt with a lot of people who try to sound a lot smarter than they actually are (I’m one of them). The latest of the bunch is a guy who asked for MySQL
7.0 claiming that he’s a MySQL programmer and that he specially programmed his database to work with MySQL 7.0. He really didn’t take it to heart very well when I told him that there is no MySQL 7.0 and the most he can hope for is 6.0x alpha (FYI for future readers a year from now, read the damn date on this post). Besides the point, the guy apparently felt like I was talking down to him so he went out of his way to mention that because he has a bachelors degree in computer science and that he’s an avid Microsoft Word user, he definately knows more than I do when it comes to doing my job. So, I gave in and agreed to upgrade him to MySQL 7.0.
The trick of the trade here is that you can essentially instal

Importing CSV Into MySQL 2007-12-08 15:53:17 The newer versions of phpMyAdmin for some reason no longer include the option to import CSV files. If you are trying to import an Excel or other delimited file, first make sure that it’s in CSV format (with Excel you can export it as CSV). Then log into phpMyAdmin or your MySQL
prompt and run this command:
load data local infile ‘/path/to/file.csv‘ into table yourtablename
fields terminated by ‘,’
enclosed by ‘”‘
lines terminated by ‘

With phpMyAdmin this is done within the ‘SQL’ section, indicated by the ‘SQL’ tab. Read more:Importing
Convert Database to UTF-8 2007-12-06 21:25:18 We seriously see a ton of customers coming in with the type of databases that are a nightmare to move over. When you’re dealing with special characters in a database, you have to make sure that the charset and collation are dumped *with* the database, so that when you move it to another server the tables and data create properly. The biggest annoyance so far is converting tables back to UTF-8, as when this is done through the MySQL shell or phpmyadmin is had to be done table-by-table. So, I wrote this simple PHP script to do it all at once:
<?php
// Database
info
$dbhost = ‘localhost’;
$dbuser = ‘db_user’;
$dbpass = ‘password’;
$dbname = ‘db_name’;
//—————
header(’Content-type: text/plain’);
$dbconn = mysql_connect($dbhost, $dbuser, $dbpass) or die( mysql_error() );
$db = mysql_select_db($dbname) or die( mysql_error() );

Using an .htaccess with PHP Compiled as CGI 2007-12-06 19:57:21 We recently started installing suPHP on a few of our servers, which is an implementation of phpsuexec, only a ton faster and with less overhead. Yesterday I posted a tutorial on how to install suPHP on a PHP5/Apache server outside of EasyApache, but today I shall go over how to enable PHP directives in your .htaccess
instead of using the php.ini.
First of all, if you’d rather use the .htaccess than the php.ini capabilities of a phpsuexec environment, then shame on you. But, we have some customers who are terrified of php.ini and would rather use the .htaccess. So what? Ok, well there is a workaround. Mr. Joye released a newer version of htscanner that now works with suPHP, and allows you to use php directives in your .htaccess just like you did when PHP was installed as and Apache module. All you have to do is download the tarball and install like any other PHP module:
wget http://pecl.php.net/get/htscanner-0.8.1.tgz
tar -xvzf htscanner-0.8.1.tgz
cd .htscanner-0.8.1

Interactive RoR Tutorial 2007-12-05 21:24:57 So it’s official, I’ve started my Ruby programming classes in school and I’ll finally be able to see what it can do. We started offering Ruby on some of our servers here and we’re all learning a little bit about it before we start offering it on our mainstream hosting…because you have to have at least one person who knows the feature well enough to help other people. From what I’ve played with so far it seems to be the same logic as PHP and perl, so let’s just see how it goes.
