How To Install flent on Fedora 34
flent is FLExible Network Tester for bufferbloat testing and more
Introduction
In this tutorial we learn how to install flent on Fedora 34.
What is flent
The FLExible Network Tester is a Python wrapper to run multiple simultaneous netperf/iperf/ping instances and aggregate the results. Tests are specified as config files (which are really Python), and various parsers for tool output are supplied. At the moment, parsers for netperf in -D mode, iperf in csv mode and ping/ping6 in -D mode are supplied, as well as a generic parser for commands that just outputs a single number. Several commands can be run in parallel and, provided they output timestamped values, (which netperf ping and iperf do, the latter with a small patch, available in the misc/ directory), the test data points can be aligned with each other in time, interpolating differences between the actual measurement points. This makes it possible to graph (e.g.) ping times before, during and after a link is loaded.
We can use yum or dnf to install flent on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install flent.
Install flent on Fedora 34 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
Fedora 34 - x86_64 20 kB/s | 6.6 kB 00:00
Fedora 34 openh264 (From Cisco) - x86_64 1.4 kB/s | 989 B 00:00
Fedora Modular 34 - x86_64 68 kB/s | 6.5 kB 00:00
Fedora 34 - x86_64 - Updates 3.5 kB/s | 6.2 kB 00:01
Fedora Modular 34 - x86_64 - Updates 17 kB/s | 5.9 kB 00:00
Metadata cache created.
After updating yum database, We can install flent using dnf by running the following command:
sudo dnf -y install flent
