The guide how to connect to iPerf3 – SpeedTest Server on Linux CentOS 8.3
- If CentOS is installed on your VM, you can skip step 2.
- To start the iperf3 server on Windows you should find the bat file named “start iperf3 server” on your desktop and run it. (Important: you should run this file after each start of VM!!!)

- After purchasing and starting the VM you should know its IP address. You can find it in the personal account of Amazon.
- Also you should allow the access by port 5201 (TCP+UDP), you can do in the properties of the Amazon firewall network.
- For the speed check you can download iperf3 client for your operating system. Download.

- To start the app you need to run the console (enter the “cmd” in the Start menu)
- In console go to the iperf3 client installation directory (in our case this is D:\Programs\iperf-3.1.3-win64)
- To get the help in usage, enter the >iperf3 command

- Enter the command for the connection speed check (for example, for 10 seconds test command is: “iperf3 -c xx.xx.xxx.xx -p 5201 -t 10” where instead of xx enter the IP address of your VM)
