How To Install Iperf3 On Windows
Iperf3 is a tool that can be used to test the network bandwidth between two EC2 instances. This guide will show you the installation process and basic usage to get you started. For the sake of example, we will be setting up two instances of the Amazon Linux AMI, but feel free to skip the following Instance Setup section if you already have two instances set up. If you want to follow along, check out the for this guide provided by Linux Academy. If you have an account with us, you can use free AWS resources in an environment that's been prepared for this guide. It's a great way to follow along.
- I am attempting to get iperf3 to run as a windows service. I see notes in documentation about the -D command and the -R command for installing the service and for removing it.
- JPerf – graphical interface wrapper for Iperf. You also might to install Java Runtime. I think it should be.bat for Windows and.sh for Linux.
Once you start the lab, you'll be provided a video that explains the steps in this guide. Note: The commands used in this guide are specific to the Amazon Linux AMI. If you’re using a different AMI for your instances, you may have to modify the commands appropriately. Instance Setup We will begin by setting up two new EC2 instances using the Amazon Linux AMI from the EC2 Management Console on AWS.

Here’s how:. Log into AWS and click the “Services” dropdown menu from the navigation bar up top. Click “EC2” under the Compute section to launch the EC2 Management Console. Use the details from your connection window to connect to the instance ( be sure to use your instance hostname instead) ssh -i 'iperf-keypair.pem' ec2-user@IPERF-A-EXAMPLE-HOSTNAME.amazonaws.com After accepting the fingerprint, you will be logged into the instance via SSH in your terminal window.
Now we can install `iperf3` using yum ( be sure to watch the output because you'll need to confirm things along the way): sudo yum -enablerepo=epel install iperf iperf3 Now that it's installed, we're ready to start the `iperf3` server on port 80: sudo iperf3 -s -p 80 If all went correctly, you should see ' Server listening on 80' Running the tests. Open a second terminal window to connect to our iperf-B instance.
Navigate back to AWS and use the Connect button to get the details of our iperf-B instance. Since we are using the same key for both, we have already ensured the iperf-keypair.pem file has the correct permissions and can skip that step and immediate connect to the instance (be sure to update the following command with the proper hostname for this instance): ssh -i 'iperf-keypair.pem' ec2-user@IPERF-B-EXAMPLE-HOSTNAME.amazonaws.com Accept the fingerprint, then install iperf3 on this second instance, just as we did on the first (again, watch the output).
Sudo yum -enablerepo=epel install iperf iperf3 Now we are ready to run iperf3 on the second instance and test the bandwidth between the two. We will instruct it to run a test using the IP address of the iperf-A instance (recall that we have the server running on port 80). Retrieve the IP of that instance from AWS. You will see the IP listed under the “Public IP” tab in the list of instances. Once you have the IP of the iperf-A instance, you’re ready to run the following command in the second terminal window (replace X.X.X.X with the IP address of the iperf-A instance you just located).

For this example, we’ll instruct to run a test on the iperf-A client ip (-c ) it to give output on an interval of 1 second ( -i 1) for a total time of 10 seconds ( t 10) and to use port 80 ( -p 80): sudo iperf3 -c X.X.X.X -i 1 -t 10 -p 80 You will begin to see output of the tests. The reported speeds may vary between subsequent tests, but they should give you a fairly accurate idea of your possible bandwidth between instances to help identify possible bottlenecks in your infrastructure.
Iperf3 The iperf series of tools perform active measurements to determine the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the measured throughput, loss, and other parameters.
This version, sometimes referred to as iperf3, is a redesign of an original version developed at NLANR / DAST. Iperf3 is a new implementation from scratch, with the goal of a smaller, simpler code base, and a library version of the functionality that can be used in other programs. Iperf3 also incorporates a number of features found in other tools such as nuttcp and netperf, but were missing from the original iperf. These include, for example, a zero-copy mode and optional JSON output. Note that iperf3 is not backwards compatible with the original iperf.
Primary development for iperf3 takes place on CentOS Linux, FreeBSD, and macOS. At this time, these are the only officially supported platforms, however there have been some reports of success with OpenBSD, Android, and other Linux distributions. Iperf3 is principally developed by /.
It is released under a three-clause BSD license. Iperf2 is no longer being developed by its original maintainers. However, beginning in 2014, another developer began fixing bugs and enhancing functionality, and generating releases of iperf2. Both projects (as of late 2017) are currently being developed actively, but independently.
