Compile John the Ripper on x86-64 Cent OS with the Jumbo Patch

I am getting ready for a password contest at Defcon that Alex and I and a few other guys from the Hashcat team are going to enter and I decided to install John the Ripper on a Cent OS box in case I needed it for anything. John is in the yum repos however the version is pretty old and it is not compiled with NTLM support so I decided to build it from source so that i could apply the Jumbo patch which adds support for a whole lot of different algorithms which are normally only available in the pro version of John the Ripper.

Below I show the steps I took to get it compiled and working on Cent OS 64 bit:

PowerDVD DX 8.1 on Windows Vista Sound Not Working, Other Sound Including Windows Media Player Working Fine

A client of mine had me troubleshoot a problem on one if his Windows Vista laptops running PowerDVD DX 8.1 to play DVD’s from the internal DVD drive. I have used PowerDVD in the past but it has been awhile so I wasn’t exactly sure what the problem was right away. He said that one of his sons had been messing with the *function button along with the number keys at the top and the sound stopped working. I looked through each of the possibilities and nothing made sense that could have caused the sound to quit working.
