How To Install eb_server_usb on Fedora 34
In this tutorial, we will discuss How To Install eb_server_usb on Fedora 34
yum package managers.
Also, we will demonstrate how to uninstall and update
eb_server_usb as well.
If you are only interested in the installation command, here is a quick answer for you:
or if you use
sudo yum makecache && sudo yum -y install entropybroker
sudo dnf makecache && sudo dnf -y install entropybroker
But if you are interested in the details with step-by-step instructions, the following information will be helpful.
Short description: infrastructure for distributing random numbers (entropy data)
First things first, you will need access to a server or computer running Fedora 34. This guide was written specifically with a server running Fedora 34 in mind, although it should also work on older, supported versions of the operating system.
Also, make sure you are running a regular, non-root user with sudo privileges configured on your server. When you have an account available, log in as your non-root user to begin.
There are several ways to install eb_server_usb on Fedora 34. You can use (links are clickable):
In the following sections, we will describe each method in detail. You can choose one of them or refer to the recommended one.
First, update dnf packages database with
dnf by running the next command:
sudo dnf makecache --refresh
After updating database,
You can install eb_server_usb using
dnf by running the
sudo dnf -y install entropybroker
Because eb_server_usb is available in Fedora 34’s default
it is possible to install it from these repositories using the
To begin, update local packages database with
yum using the following command.
sudo yum makecache --refresh
Now can install eb_server_usb package on your server/computer by running the following command:
sudo yum -y install entropybroker
To update all the packages available on the system:
If you want to update a specific package like eb_server_usb in this example you should use the following command:
yum update entropybroker
To downgrade a package to an earlier version:
yum downgrade entropybroker
When you run the
dnf update, all system packages with available updates are updated.
However, if you want to upgrade a single package, then you would have to pass the package name as
the argument to the dnf update command.
dnf update entropybroker
To uninstall only the
eb_server_usb package you can execute
sudo dnf remove entropybroker
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).
You now have a full guide on how to install
yum package managers.
Also, we showed how to update manually as a single package and different ways to uninstall
the eb_server_usb from Fedora 34.
