Iperf was orginally developed by NLANR/DAST as a modern alternative for measuring maximum TCP and UDP bandwidth performance. Iperf allows the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss.

We’ll setting up 1 iperf client and 1 iperf server.

1. Iperf server

The easy way

root# apt-get install iperf

Compile manually

root# apt-get install build-essential
root# wget http://jaist.dl.sourceforge.net/project/iperf/iperf-2.0.5.tar.gz
root# tar zxvf iperf-2.0.5.tar.gz
root# cd iperf-2.0.5
root# ./configure
root# make
root#make install clean
root#iperf -s -D {run as server mode, and create a daemon}

2. Iperf client

Follow exactly above step to install iperf

To start a test execute below command

root#iperf - c <iperf-server-ipaddress-here>
