Change cPanel’s email password through command line

October 15, 2017October 15, 2017 xUx Leave a comment

This script will help you change any email’s account password without using cPanel, this is done through the command line. It was written in PHP but mostly uses shell commands so I guess it was easier to use elements from both worlds.

Use it at your own risk, this script requires to be executed as root and was done for educational purposes.

osTicket Red theme 1.6 RC4

March 8, 2009July 9, 2009 xUx 21 Comments

Hello there 🙂

Based on my old post (http://xux.in/blog/post/osticket-theme-1-6-rc4/), I decided to do more templates for osTicket 1.6 RC4 and RC5, because (and accidentally), the main theme code I did, allows you to integrate new templates in just a few minutes. So I downloaded some free css templates (like 12) and started to play with them and I’ll release 1 post for each template. ~~The first part of the post will contain only the theme’s screenshots and once I fix some the code and test it enough I’ll update the post with the full template translated in english and spanish.~~

Here is how it looks! 🙂

Download osTicket Red Theme (3783) (Compatible with 1.6 RC5)

* Note: This template is ONLY for the client side, not for the staff/admin area.

osTicket theme 1.6 RC4

February 23, 2009November 30, 2010 xUx 65 Comments

As you already know osTicket is a support ticket system which is very easy to use and free. Developers from osTicket are back, they fixed a few bugs and cleaned a little bit most of the code.

Features:

Multilanguage client interface: You can add as many languages as you want for the client side.
Error messages can be “catched” and identified by a unique MD5 key which you can translate it in your language file.
You can configure the Ticket ID field to be a password field or just a text field for “security”.
It comes with 2 cool, light and fully XHTML valid themes which you can easily modify colors and also the HTML because of it’s clean design.
It has a built-in CAPTCHA module that will protect you from SPAM.
Search tickets based only on ticket’s subject.
Easy to install.
Last but not least, it’s 100% free, but that doesn’t mean you are allowed to remove credits 😉

It has been tested a while now but it’s still on a beta stage, however, you might find some bugs and I’ll be happy to get some feedback from you. I didn’t include the Spanish language file this time, but I’ll do it someday 🙂 If you want to translate it to other language feel free to send me your language file and I’ll include it in the next release 😉

Here are some screenshots:

This specific version is a patched one from Nov/30/2010 which includes all the post-install instructions here, spanish translation included and all the patches needed to work with osTicket 1.6.0 (Stable), get it here: Download osTicket CTheme for 1.6.0 (Stable) (4361)

*** This is still very old news, keeping them there just for the archives ***

Are you still reading? Ok, you deserve it… Download osTicket CTheme (4421) (Compatible with 1.6 RC5)
Necesitas el tema en español? Descarga el archivo osTicket CTheme Spanish Language (2832)

When you uncompress the file it will create a directory called “client”, that directory should be copied to osTicket’s root dir and the rest of the installation instructions are in the README file, have fun!

** Post install notes and bug fix:

The file thankyou.inc.php from this template has a code error in line 10: $ctlang->docatch($msg?) which should be changed for $ctlang->docatch($msg)?
Inside osTicket’s root dir, edit the index.php and comment (or delete) all the html code in order to see the template display correctly, then you just need to add this line before the footer in included: require(CLIENTINC_DIR.’main.inc.php’);. This bug and others will be fixed in the next release soon.

PHP EditDNS Updater for Linux

December 18, 2008October 15, 2017 xUx 1 Comment

This is a simple PHP script which will update your dynamic DNS records using EditDNS.

Features:
– You can configure as many records as you want.
– Supports HTTP and HTTPS.
– For PHP 4x and higher compiled with sockets.
– Simple validation.

Here is the code: (editdns.php)

#!/usr/bin/php -q
<?

$port = 443; // use 80 if you dont wanna use SSL
// add as many arrays as you want, first element is the record
// and the second is the password
// $data[] = array('myrecord1.domain.com','mypass1');
// $data[] = array('myrecord2.domain.com','mypass2');
// ... etc etc etc ;)
$data[] = array('somerecord.resolveme.com','blahblah123');
$sleep = 1; // seconds we should sleep before updating another record

// main loop
if (!is_array($data)) die("Nothing to do\n");
foreach ($data as $v) {
  echo "Updating $v[0] ... ";
  if(_send($port,"p=$v[1]&r=$v[0]")) echo "[OK]\n";
  sleep($sleep);
}

function _send($port=443,$args="") {
  if ($port == 443) $proto = "ssl";
  else $proto = "http";
  $fp = fsockopen("$proto://dyndns.editdns.net",$port,$errno,$errstr,10);
  if (!$fp) die("\nCouldn't establish connection\n");
  $out = "POST /api/dynLinux.php HTTP/1.0\r\n";
  $out .= "Host: dyndns.editdns.net\r\n";
  $out .= "Content-Type: application/x-www-form-urlencoded\r\n";

  $out .= $args;
  //echo $out;
  fwrite($fp, $out);
  while (!feof($fp)) {
    $res .= fgets($fp,1024);
  }
  fclose($fp);
  $parts = explode("\r\n\r\n",trim($res));
  //print_r($parts);
  // checking output
  if (preg_match("/record has been updated|record already exists/i",$parts[1])) return 1;
  // anything else should be an error
  echo "[ERROR]\n\t$parts[1]\n";
  return 0;
}

?>

cpanel 535 Incorrect authentication data

November 24, 2008November 24, 2008 xUx 1 Comment

I ran into a small issue when migrating some sites to a cPanel server, tried a few “tricks” (/scripts/* –force hehe) without luck till I found a great post which pointed me the solution, and it is as simple as that!

Since I’m a very lazy guy, I wrote a tiny script which does what Jerry (from cPanel forums) said/explained. Copy the code, save it and execute it. By default it won’t do anything but show the directories and files current state and how they should be. If you see something is not as it should be then you should change the $debug var to false in order to allow the script to do the job. After that everything should be fixed and if not don’t blame me, you can always do that manually 😉
