Supported distro

  • Ubuntu 20.04 x86_64

  • Ubuntu 22.04 x86_64 (but see notes below)

Installation

Run in your host console on behalf of root user the following command:

curl -s https://raw.githubusercontent.com/quantum-sp8de/quantra-installer/master/install_qrandom.sh | sudo bash -s -- -r generator

At the end of the installation you should see the similar output in your console: Installation OK Run 'quantra' to start working

Device registration

In case you are running first time, before running main quantra console application, it is required to register you device. Run quantra-registration script to do that, for example: sudoquantra-registration --device /dev/ttyUSB0 --server_url <URL>

where

  • --device - path to USB device in Linux host (usb-inserted)

  • --server_url - url of registration server

After registering the device, register the in the network.

First run and random generation

To start generating randoms, run quantra application in your console:

quantra

If you have not configured the application before or do not have configuration file in quantra configuration directory ( ~/.quantra/) yet, quantra will ask you to input configurations on startup. First time you have to input the following configurations:

  • application password - enter any password than will be used for consequent quantra runs

  • account - your user account name in blockchain

  • blockchain url - the url of blockchain

  • private key - private key of account to operate

Further quantra runs will use this saved configuration from ~/.quantra/quantra.yaml. Only application password will be prompt, which must match the one entered on first run.

See help and descriptions for additional options of quantra quantra --help

Notes:

  • If you have error accessing QCicada device like the following:

could not open port /dev/ttyUSB0: [Errno 13] Permission denied

do not forget to add user to dialout group to access serial devices:

sudo usermod -a -G dialout $USER

  • In case errors are showing while running qunatra on Ubuntu 22.04 like the following:

ValueError: unsupported hash type rmd160

make sure the following fixes are made for enabling old crypto algorithm support in your /usr/lib/ssl/openssl.cnf:

 openssl_conf = openssl_init

 [openssl_init]
 providers = provider_sect

 [provider_sect]
 default = default_sect
 legacy = legacy_sect

 [default_sect]
 activate = 1

 [legacy_sect]
 activate = 1
