iperf.scottlinux.com – Public iperf Server [Update: iperf3 only]

By | 2013/07/17

I created a public iperf server to test your internet connection (iperf3 only). Here are the details!


Nov 2014 Edit: I have had to change this server to be iperf3 only. Sorry!


The server is located at:

iperf.scottlinux.com


Ok now what?
1. iperf3 is required for this server.



Fedora and CentOS EPEL users can install iperf3 with:

$ sudo yum install iperf3

Older versions of Ubuntu and Debian:

For now, must build iperf3 from source from https://github.com/esnet/iperf .

Users of Debian Jessie, iperf3 is available!


2. Once iperf3 is installed, run:

$ iperf3 -c iperf.scottlinux.com

This will test the outgoing bandwidth of your internet connection as one possible test.


Here is an example output:

$ iperf3 -c iperf.scottlinux.com
