Troubleshooting your network with Iperf

Follow

Iperf is a cross-platform tool for network performance measurement and tuning. 

Iperf has client and server functionality and can create data streams to measure the throughput between the two ends in one or both directions, with a time-stamped report of the amount of data transferred and the throughput measured. The quality of a network link can be tested with LatencyJitter and the Packet Loss measured.

 

How to Install

Please download the latest version of iperf3 following this link: https://iperf.fr/iperf-download.php

# make sure the program have premission to run
talkdesk$ chmod u+x ./iperf3

 

How to run 

Now that you have configured iperf, in the console, you can run the iperf in client mode to connect with our server.

  # In this exemple 
# -c: using client mode

# -p: in the port 5200
# -u: using UDP
