rng-tools configuration

English Hardware

Hi there,

I am trying to configure a usb true random number generator from ubld.it. I have been following their instructions as shown on their website http://ubld.it/products/support/truerng-install-guide. The problem is, I cannot find the configuration for the rng-tools initscript. Do you guys know where to locate it?

Thanks for all your help
Ron

Hi and welcome to the Forum :slight_smile:
We use systemd these days so it a service file no init scripts;


systemctl status rng-tools (is it running?)
systemctl start rng-tools (if not start it)
systemctl enable rng-tools (for it to start on boot)

Hi Malcolm,

Thanks for replying and providing information regarding rng-tools. I have another question. How do I modify the rng-tools to set the input source for random data as following HRNGDEVICE=/dev/TrueRNG?

Thanks,
Ron

Hi
I would suggest editing the service file and adding your option in
the [service] part;


Environment=HRNGDEVICE=/dev/TrueRNG
