Flent: a complete test kit to test network connections


Our networks have become essential to connect to all the computers on the planet and allow quick access to information. However, when connections fail, they are often the most annoying for users and sometimes difficult to diagnose. To help you with this, or to perform benchmarks, you can have the Flent app handy.

It is a free and open source tool that is available for Linux (also for macOS and FreeBSD), both in the repositories and in some app stores, such as the Ubuntu Software Center. Its name comes from Flexible Network Tester, and is written in Python, with multiple calls to various network tools that will be automated to launch results of the state of your network and display graphical information.

Therefore, Flent is a comprehensive assessment tool network comparison that will allow you to:

  • Perform network tests using multiple popular assessment tools with greater ease and being able to reproduce the tests whenever you want without having to execute each command separately.
  • All managed from a simple and intuitive GUI, in which you can also graphically view all the data and results for analysis.
  • You can combine and aggregate data and produce quality graphics.
  • Captures metadata from local and remote hosts to store along with analyzed data.
  • Collect secondary data on CPU usage, WiFi, Disks, socket statistics, etc. All storable for later analysis.
  • Experimental batch executions can be specified to automate the tests (netpref, iperf, Bufferbloat, timestamp, ping time,…).

With all this you can also make comparisons between several networks or determine where the performance issues that you suffer, and combine it with other tools such as Ettercap, Wireshark, Packet Sender, etc., to monitor your networks ...
