Hashcat not running on my CPU - oneup - 06-09-2019

I am trying to run hashcat on both my CPU and GPU because by GPU is not that fancy. I installed the OpenCL drivers from intel (install_GUI.sh from l_opencl_p_18.1.0.015) and the OpenCL packages as mentioned in the wiki. After much trouble I managed to get hashcat to recognize my CPU:

Code:
hashcat -I hashcat (v5.1.0-1138-g581839d4) starting... * Device #2: CUDA SDK Toolkit installation NOT detected.             CUDA SDK Toolkit installation required for proper device support and utilization             Falling back to OpenCL Runtime OpenCL Info: ============ OpenCL Platform ID #1  Vendor..: Intel(R) Corporation  Name....: Intel(R) CPU Runtime for OpenCL(TM) Applications  Version.: OpenCL 2.1 LINUX  Backend Device ID #1    Type...........: CPU    Vendor.ID......: 8    Vendor.........: Intel(R) Corporation    Name...........: Intel(R) Core(TM) i7-5500U CPU @ 2.40GHz    Version........: OpenCL 2.1 (Build 0)    Processor(s)...: 4    Clock..........: 2400    Memory.........: 1969/7876 MB allocatable    OpenCL.Version.: OpenCL C 2.0    Driver.Version.: 18.1.0.0920 OpenCL Platform ID #2  Vendor..: NVIDIA Corporation  Name....: NVIDIA CUDA  Version.: OpenCL 1.2 CUDA 10.2.120  Backend Device ID #2    Type...........: GPU    Vendor.ID......: 32    Vendor.........: NVIDIA Corporation    Name...........: GeForce 920M    Version........: OpenCL 1.2 CUDA    Processor(s)...: 2    Clock..........: 954    Memory.........: 501/2004 MB allocatable    OpenCL.Version.: OpenCL C 1.2    Driver.Version.: 430.14

When I run hashcat with "-d 2" it runs fine on my GPU (but only at ~135kH/s). But when I try to run it on my CPU with "-d 1" it says:

Code:
hashcat (v5.1.0-1138-g581839d4) starting... * Device #2: CUDA SDK Toolkit installation NOT detected.             CUDA SDK Toolkit installation required for proper device support and utilization             Falling back to OpenCL Runtime No devices found/left.

How could this be? It's actually detecting both devices, it runs on my GPU but when I specify the CPU it says no devices found?

--opencl-device-types 1,2 (or short -D 1,2) to enable both CPU and GPU cracking. see --help output

That works, thanks a lot. I did actually study the "--help" output and I can't believe I missed that, please forgive me (I'm a newbie)

I guess you know why Wink
