How To Install entropybroker on Kali Linux
Introduction
In this tutorial we learn how to install entropybroker on Kali Linux.
What is entropybroker
entropybroker is:
Entropy Broker is an infrastructure for distributing cryptographically secure random numbers (entropy data) from one or more servers to one or more clients.
It allows you to distribute entropy data (random values) to /dev/random devices from other systems (real servers or virtualised systems). It helps preventing that the /dev/random device gets depleted; an empty /dev/random-device can cause programs to hang (waiting for entropy data to become available).
This is useful for systems that need to generate encryption keys, run VPN software or run a casino website. Also virtual systems that have no good sources of entropy like virtual servers (e.g. VMware, XEN and KVM (although KVM has the virtio_rnd driver)).
Entropy Broker is an infrastructure consisting of client-daemons that fill /dev/random and server-daemons that feed the central entropy broker-server. The server-daemons can gather random values by measuring timer frequency noise, analysing noise from a unused audio-device, noise from a video source (webcam, tv-card) and random values from a real hardware RNG (random number generator).
There are three methods to install entropybroker on Kali Linux. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install entropybroker Using apt-get
Update apt database with apt-get using the following command.
sudo apt-get updateAfter updating apt database, We can install entropybroker using apt-get by running the following command:
sudo apt-get -y install entropybrokerInstall entropybroker Using apt
Update apt database with apt using the following command.
sudo apt updateAfter updating apt database, We can install entropybroker using apt by running the following command:
sudo apt -y install entropybrokerInstall entropybroker Using aptitude
If you want to follow this method, you might need to install aptitude on Kali Linux first since aptitude is usually not installed by default on Kali Linux. Update apt database with aptitude using the following command.
sudo aptitude updateAfter updating apt database, We can install entropybroker using aptitude by running the following command:
sudo aptitude -y install entropybrokerHow To Uninstall entropybroker on Kali Linux
To uninstall only the entropybroker package we can use the following command:
sudo apt-get remove entropybrokerUninstall entropybroker And Its Dependencies
To uninstall entropybroker and its dependencies that are no longer needed by Kali Linux, we can use the command below:
sudo apt-get -y autoremove entropybrokerRemove entropybroker Configurations and Data
To remove entropybroker configuration and data from Kali Linux we can use the following command:
sudo apt-get -y purge entropybrokerRemove entropybroker configuration, data, and all of its dependencies
We can use the following command to remove entropybroker configurations, data and all of its dependencies, we can use the following command:
sudo apt-get -y autoremove --purge entropybrokerDependencies
entropybroker have the following dependencies:
