Require HTTPS For ClientExec Installed In Sub Directory

If you have ClientExec installed in a sub-directory say /clientexec and want to require HTTPS only for ClientExec the easiest way to accomplish this is by putting a .htaccess file inside of the sub directory itself. There are numerous solutions to this posted as CE Knowledge Base Articles and within the CE forums but many of them did not work for me so I wanted to post the solution that worked on setup using CentOS as the operating system and using Apache/PHP/MySQL on that platform.

Failed loading /usr/sbin/ioncube_loader_lin_5.2.so: /usr/sbin/ioncube_loader_lin_5.2.so: undefined symbol: zend_error_noreturn

After upgrading PHP recently on a CentOS Linux server from PHP 5.2.X to PHP 5.3.X I ran into numerous minor issues. One of the issues was with a web application that requires the ionCube PHP Encoder libraries to function properly. After upgrading PHP I noticed some errors in the Apache error logs including the ionCube Apache module that was failing to load. Below I display the entire error from the Apache error_log file and how to easily resolve the issue by installing a single package via the Yum Package Manager.

Warning: Can’t Load Net::Whois::IP Module, Whois Queries Desabled

In going through all the tools with Alex on Backtrack I have discovered a few bugs and missing modules or libs. I will be writting posts on how to fix them but I will also be adding the fix’s to Backtrack svn as well. This morning I was writting the article on Dnsenum by my buddy Barbsie and I ran into a missing perl module.

bash

  1. root@666:/pentest/enumeration/dnsenum# ./dnsenum.pl --enum -f dns.txt --update a -r cnn.com
  2. dnsenum.pl VERSION:1.2
  3. Warning: can't load Net::Whois::IP module, whois queries desabled.

Below I will show to to download and install the needed module:

LM_Sensors on Cent OS 5.4: How To Get And Install The Coretemp Module

If you have been following my progress over the last few days you will know that after a complete rebuild of the tools server and a change of the operating system, I have been working hard to get all our temp monitoring back online. The server previously ran Gentoo Linux, which although is still my favorite distro, is just not suited for a production server environment.  So we decided to go with Cent OS which is a very well built distro aimed at running on production servers. My only complaint is that its kernel and some of its packages are a little bit out of date.  On the bright side, this has given us a few challenges to work through and more importantly some good articles to share.  So after getting my GPU temps going and graphing I turned my attention to the cpu. We are currently running a Intel i7 965 Extreme edition which I just put in last night. In the following article I will show how I eventually got lm_sensors and the coretemp module to work on Cent OS 5.4
