[iperf] Testing the Network Speed Between Two Machines in 4 Steps
How do you test the network speed between two boxes?
iPerf is a tool for active measurements of the maximum achievable bandwidth on IP networks (by iperf.fr).
Using Iperf is simple, run one instance on a server (receiving client) with the -s option and another instance on the testing client (sender) with the -c option.
1. Install (Server Linux)
$ wget http://sourceforge.net/projects/iperf/files/iperf-2.0.5.tar.gz/download
$ tar -xzvf iperf-2.0.5.tar.gz
2. Install (Client MAC)
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null
$ brew install iperf
3. Run (Server Linux)
iperf -s — this will then start the server, listening to TCP port 5001 by default. You can change to any port you like (by cjcott01).
$ ./iperf-2.0.5/src/iperf -s
4. Run (Client Mac)
iperf -c 111.222.333.444 which is the ip address of the listening server (by cjcott01).
$ iperf -c 111.222.333.444 //target ip
