Tonight I was downloading some packages from a community FTP server I am a member of and noticed that the transfer speeds were not showing after I started to process the FileZilla FTP transfer queue. Initially I figured I must have unchecked a toolbar or accidentally modified a view setting without knowing it. After reviewing the…
I have been working on a project using oclHashcat this afternoon and started to look into an error that has existed on a development server where we use oclHashcat for quite some time. After some digging around I am confident that regardless of the error existing there is not an issue but I wanted to…
Recently we have been doing a lot of testing of oclHashcat on CentOS Linux servers. The oclHashcat application takes advantage of the GPU’s, or Graphical Processing Units, of Nvidia graphics cards or ATI graphics cards. Anyhow one of the servers we have been testing with has four Nvidia 295 GTX’s and at times was receiving an…
This weekend I was investigating the capabilities of the two NVIDIA graphics cards in my laptop and a password cracking application called oclHashcat. The oclHashcat application uses OpenCL, the Open Computing Language, to utilize the processing power of your graphics cards GPU’s to crack passwords. My laptop is a Dell Studio XPS 1340 which utilizes…
I have been using Hashcat and oclHashcat a lot in recent weeks but have been limited to primarily using it on Linux servers so I decided to give it a shot on a couple Windows machines. Below I describe how I got oclHashcat operational on Windows 7 Ultimate 32-Bit on a desktop computer with a…
Recently some pretty major advances have come around in the world of GPU based hash cracking. Up untill now there was not much for Linux which would utilize multi GPUs to crack password hashs. This has been changed with the release of Oclhashcat. The release of oclhashcat signifies a signifigant jump in the speed on…
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…
If you have been keeping up with the development on our tools server you will know that we just did a big rebuild and I was looking for a way to monitor the GPU temperatures. Yesterday I wrote a article about how to get these temperatures on a linux server which does not have a…
So as every one knows we just rebuilt our massive cracking server. On the old server I was doing temperature monitoring with LM_Sensors, which for CPU temps is very good but I was not to sure about its accuracy on GPU Temperatures. So I decided to do some investigation into another solution.
