Specifics of detection tools operation on NVIDIA

...

GPUs in Linux OS

By default, the Nouveau driver can be installed in Linux OS. This driver does not guarantee stable operation when using NVIDIA graphics cards for decoding Axxon Next detection tools (see Configuring detection tools).

...

If the operating system uses the installed driver to work, the driver version will be displayed. Otherwise, if the current driver is installed, but the operating system uses the Nouveau driver, you need to add it to the exclusions list and restart the computer. The Below is an example of Ubuntu commands to add the Nouveau driver to the exclusion list using Ubuntu as an example:

sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"

After restarting, the operating system will use the installed NVIDIA driver.

Problem with memory dump in Astra Linux SE environment

Sometimes, when Axxon Next modules are shut down incorrectly in Astra Linux SE environment, memory dumps are generated incorrectly and cannot be decrypted. To solve the problem, it is necessary to disable the blocking of the Ptrace service in Astra Linux SE environment using one of the following methods:

• using fly-admin-smc graphical tool: go to Control Panel → Security → Security Policy → Security Settings → Kernel Options.

• using console mode: run the following command:

  Code Block
  astra-ptrace-lock disable

  
  

To check the status of the Ptrace service, run the following command:

systemctl is-disabled astra-ptrace-lock

The following messages may be received in response to the command:

• enabled—Ptrace service is enabled;
• disabled—Ptrace service is disabled;
• Failed to get unit file state—Ptrace service is not activated.
