Connection to iPerf3 – SpeedTest Server on CentOS Stream 8
- After purchasing and starting the VM you should know its IP address. You can find it in the personal account of Azure. (You need to select the virtual machine from the list. By clicking the item “Overview”, your IP is displayed in the line of “Public IP Address”).
You should allow the access by port 5201 (TCP+UDP), which you can do in properties of the Azure firewall network.
- For the speed check you can download iperf3 client for your operating system. Download.
- To start the app you need to run PowerShell or console (enter the “cmd” in the Start menu)
- In console go to the iperf3 client installation directory (in our case this is D:\Progs\iperf)
- To get the help in usage, enter the >.\iperf3 -h 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)
- When the VM is started, the server is turned on automatically. If this does not happen, you should connect to a VM. To do this you need the PuTTy application to connect via ssh. You can download it at the following link – Download
- Run Putty, enter the VM address in the “Host” field, and click “Open” to connect.
- In the opened console you will need to enter a username and password that were specified while the VM was being created (you’ll not see the password in the console while entering it).
- Type the command iperf3 -s in order to run the server
Now you can use iPerf3 – SpeedTest Server on CentOS Stream 8.
