Wierd Problem With Intel OpenCL (CPU) and Hashcat Options.
#1
Hey

I had the common error message:

Code:
Not a native Intel OpenCL runtime. Expect massive speed loss.

You can use --force to override, but do not report related errors

for my intel CPU on a Debian based Linux distribution. So i uninstalled the "The pocl project" Cpu driver and installed the  "OpenCL™ 2.0 GPU/CPU driver package for Linux* (64-bit)" from here:
https://software.intel.com/en-us/article...cl-drivers

Because i couldn't use the Runtime installer (ubuntu,Red Hat only) i used a "install" way which i found in this post:
https://hashcat.net/forum/thread-6079.html

(it just copies the openCL files in the right directories):
Code:
$mkdir intel-opencl 
$ tar -C intel-opencl -Jxf intel-opencl-r3.1-BUILD_ID.x86_64.tar.xz 
$ tar -C intel-opencl -Jxf intel-opencl-devel-r3.1-BUILD_ID.x86_64.tar.xz 
$ tar -C intel-opencl -Jxf intel-opencl-cpu-r3.1-BUILD_ID.x86_64.tar.xz 
$ sudo cp -R intel-opencl/* / 
$ sudo ldconfig

Everything worked fine and Hashcat  recognized the driver. I checked it with:
Code:
Hashcat -I
Then i tried
Code:
Hashcat -b -D 1,2

and it worked too.

But after that, i tried to crack a hash with a simple brute force attack
and when i tried to check the status, i noticed that the buttons/Options don't work.
It just jumps in a new line,like the script failed or something like that.
I found a similar problem in this thread:

https://hashcat.net/forum/thread-6202.html

But he used Ubuntu and others couldn't recreate the problem..
I want to use my gpu and cpu  separately with Hashcat but its not possible at the moment.
My question is if someone have a idea how i can solve or find the reason for that problem.
I didn't saw any Errors so i couldn't find the problem...

Sure you didn't have your capslock on? Just a possibility, I know I've done it a few times.

Could also just run a test scenario with one of the example hashes on the Wiki to see if its functioning still. It should provide you with the password in the potfile if found.

HI
Thanks for the answer!

But this cant be the reason because when i removed the driver, it worked again!
I have even restarted the computer twice, but still the buttons did not work! 
It only worked again when I removed the driver.


If someone has a idea or need some more information, please answer!
