To find out which GPU you have, you can run: You can safely remove those kernel files which correspond to GPUs that you do not have in your system. It's unlikely that you have all GPU types in a single system.
#USING TRUECRYPT 64 BIT#
So if you use a 64 bit system you don't need the 32 bit kernels at all and you can safely remove them.īut there is more. For NVidia systems there are kernels for 32 bit and 64 bit. This ensures maximum performance.ĭepending on if you have a Nvidia or AMD system, the bitness is also important. When hashcat starts up it queries model from your GPU and loads the corresponding kernel for it. The most space is taken from the precompiled kernel files. It depends on your system, but usually you do not need all the files within the extracted hashcat folder. I got this error message: undefined symbol: nvmlInit_v2 Error, what does it mean? This could be because the mapping somehow failed and the device is an overdrive 6 GPU instead or something similar.Ī possible workaround is to set the fan manually to 100% and use the -gpu-temp-disable flag in hashcat. In this particular case, hashcat fails to get the temperature of the GPU which uses overdrive 5. There is little hashcat can do to avoid this problem since the bus id and device id are sometimes the same (reported by OpenCL), even if we are dealing with 2 “different” (but similar) GPUs.
It could, for instance, fail when you have a multi-GPU setup where some devices are identical (same model/make etc), and you specify -d 1/-d 2. Hashcat does some fuzzy matching, due to the lack of a unique and consistent way to identify the devices, to try to match those devices with the best accuracy possible, but still sometimes this fails. ADL and OpenCL do use some different means to describe/priorize/sort/name/identify the different devices, which can contribute to this problem. The most likely reason for this problem is that hashcat could not perfectly map the found and supported OpenCL devices to the devices that the ADL (AMD Display Library) did find. You may be surprised to learn that your favorite Linux distribution is not officially supported by the driver, and often for good reasons. Please, always double-check if AMD or NVidia do officially support the specific operating system you want to use. In these instances, you may not be able to receive support.
#USING TRUECRYPT DRIVER#
If you prefer to use a different operating system or distribution, you may encounter some problems with driver installation, etc. You should prefer to use this specific operating system and driver version because it is always thoroughly tested and proven to work. There is a detailed installation guide for linux servers. Do not use the version from your package manager or the pre-installed one on your system.
#USING TRUECRYPT INSTALL#
What should I do?).Īt this time you need to install the proprietary drivers for hashcat from and amd.com respectively. If you have already a different driver installed than the recommended from the before mentioned download page, make sure to uninstall it cleanly (see I may have the wrong driver installed. How does one install the correct driver for the GPU(s)?Īlways make sure you have downloaded and extracted the newest version of hashcat first. This is the preferred and only supported method to “install” hashcat.
#USING TRUECRYPT ARCHIVE#
In case something isn't working with the packages you download via your package manager, we encourage you to just download the hashcat archive directly, enter the folder, and run hashcat.
#USING TRUECRYPT UPDATE#
$ sudo apt-get update & sudo apt-get upgradeĮven if this is supported by some distributions, we do not directly support this here since it depends on the package maintainers to update the packages, install the correct dependencies (some packages may add wrappers, etc), and use reasonable paths.
$ sudo apt-get update & sudo apt-get install hashcat For example, you can use the following under Kali Linux: If your operating system or linux distribution does have some pre-build installation package for hashcat, you may be able to install it using those facilities. Please note, your GPU must be supported and the driver must be correctly installed to use this software. You only need to extract the archive you have downloaded. There is no need to really install hashcat or hashcat legacy (CPU only version).
