One of the things I wanted to verify is if there is a new BIOS version available but first needed to verify the current BIOS version installed. Below is information on how to determine what BIOS version a Linux server is using while the server is running.

Disable PHP allow_url_fopen For Security Reasons

Recently I was doing a security audit on a Linux server and noticed some Apache and PHP items that needed to be modified to make the server more secure. One of the items that should be disabled is allow_url_fopen because the risk that it can be abused. The issue is that allow_url_fopen is on by default even though many times it is never used on a server. Modify the below line in the Linux servers php.ini file which typically located in the /etc directory.

Play HD DVD’s On Windows 7 Using Xbox 360 HD DVD Player

The LCD TV in my office started having issues with the LCD screen a couple weeks ago so I had to take the TV in to get the screen replaced. Luckily the LCD panel happened to be under warranty or I would have been out $2200. Regardless though it left me without the TV in my office which I use not only for TV but also for a second computer screen from one of my desktop computers so I was limited to using my HP w2408h monitor to watch movies, etc. One of the things I wanted to accomplish was to get the HD DVD player from my Xbox 360 working on a Windows 7 computer so I could watch some older movies on the monitor while the TV was in the shop. Below is information regarding what issues I ran across and how to overcome them which really is limited to the software used to play the HD DVD movies.
