On one of my servers I run a couple sites via Django and recently when I upgraded the server it broke the Django sites that were running via FastCGI. After some investigation I was able to find the issue which happened to be a basic conflict between python2.4 which is the default python version on CentOS Linux and python2.6 which I installed to run via python26 instead of python. This way I can change the environment of any site that needs it to Python version 2.6 without much hassle. Below I describe the error in detail as well as what resolved the issue.

Yesterday I wrote an article about securing your /tmp and /var/tmp directories on a Linux server because I had found some files uploaded to the /tmp directory via the apache user. After locking down those directories I wanted to verify that there were no other issues on the server so I installed Rootkit Hunter and Rootcheck which are two applications that will assist you with verifying the integrity of your Linux server. Below is information on installing Rootkit Hunter and Rootcheck as well as information on how to use each of them effectively.

Someone sent me a WebEx webcast they wanted me to view this afternoon. The file had a .WRF file ending which stands for WebEx Recording Format which is one of the two file formats that WebEx webcasts are saved as. The other format that WebEx files are saved as is the ARF or WebEx Advanced Recording Format. Typically you could simply download the WebEx Player available by clicking here however you may want to convert this video, which requires the WebEx Recording Editor, to provide to others in a format they can view without having to install an application. It took me awhile to figure out how to convert this file properly since I only seemed to be able to find the older WebEx Editor versions. I finally signed up for a trial account and was able to download version 3 of the WebEx Recording Editor which allowed me to convert to WMV format and from that I was able to convert to any other video format including AVI, MP4, XVID, and MPEG. Follow the directions below to first convert the .WRF to .WMV and then the second set of directions if you want to convert to another video format.

Earlier I received a webcast that a colleague of mine wanted me to review to see if a certain service would be a fit for our network. The file he sent over had a .WRF file ending which after some research I found out was a WebEx file meaning WebEx Recording Format. To play this type of file you need the WebEx .WRF Player which can be downloaded here or the files can be converted to WMV (Windows Media Format) to play in the Windows Media Player. To convert the file you have to use the WebEx Editor which allows you to open a .WRF file and export to WMV format. When I attempted to export to WMV I received an error which I describe below along with how I was able to resolve the error.

I recently was installing Django for a test project and needed to upgrade Python on a CentOS server to 2.6. The current revisions available via yum on CentOS are 2.4. The yum package manager requires Python 2.4 still to function properly so upgrading Python to 2.6 manually will break the CentOS yum package manager. After a little bit of research I found a yum repository that would allow you to install Python version 2.6 in parallel to Python version 2.4. Below I explain how to install the new Python version, not break the yum package manager, and modify a Django project that references Python to use the 2.6 version instead of the 2.4 version.
