Use paxctl to inspect and change the pax settings.



paxctl -h

paxctl -v [application name]

First of all, make sure the libraries of CUDA are loading properly by making sure the following lines are at the file /etc/env.d/99cuda :



cat /etc/env.d/99cuda



PATH=/opt/cuda/bin:/opt/cuda/libnvvp

ROOTPATH=/opt/cuda/bin

LD_LIBRARY_PATH=/opt/cuda/lib64:/opt/cuda/lib




Finally, make sure some of the applications are set to proper pax settings. For example, cudaHashcat-plus64.bin and Cryptohaze-Multiforcer which are running with CUDA but they are not setting with pax flags properly at the current version.



Make sure the pax settings should be shown as the following :







Known Issue



The current version/update as on April 29, 2013, the pyrit does not work properly with CUDA. Since pyrit is written in Python, the paxctl does not work at all. According to one of the developers, the pyrit will be removed from the distribution.



Thats all! See you.
