This is Iperf v2.0.x, a tool for measuring Internet bandwidth performance.
See the doc directory for more documentation.

Briefly:

Do one-time if needed:
  dnf install gcc
  dnf install gcc-c++
  dnf install automake

then to build do:
  ./configure      -- configure for your machine
  make             -- compile Iperf
  make install     -- install Iperf, if desired, from root

and to use:
  iperf -s               (on machine "foo.bar.edu")
  iperf -c foo.bar.edu   (on some other machine)
  iperf -h               (for help screen)
  iperf -v               (for version information)

and for more information (requires make install)
