I am looking for a cross-platform iperf client module for Python 2.7.

Please note that it must be freely usable in a commercial environment, and, hopefully, have good documentation.

  • Hm, a bit broad, isn't it? Not being familiar with iperf I cannot tell for sure, though. Any specific features you need?

  • Nope, not broad at all. I need a 100% port of full iperf functionality - as a Python module. Originally, I almost didn't have the second sentence & was going to repalec by "shortest valid question ever?@ ;)

  • "This is a program to extract bandwidths and data transfers from iperf output", so it doesn't run iperf, just parses the output. Nvm, I have already coded both, but +1 for a useful module, which should help others in the future.

You can perform all of the functionality of iperf with scapy, (and a lot more), just don't let your companies IT network & security team know that you are using it they will throw a fit at what it can do.

  • Create & send any packet, literally any!
  • Receive traffic
  • Time monitoring, etc
  • Cross Platform
  • The documentation is reasonably good for such a huge capability
  • There are python 2 (the original) and python 3 versions but be sure to ask the author of the one that you are using any questions
  • It is GPL so you should be able to use it in any environment but you may not be able to link it in or distribute it in a commercial package without applying GPL to that package.

    Well, you know my IT department from other posts ;-) I wil accep tthis as the answer, since it will help others in future. And then I will slink off and code result = subprocess.check_output(iperfCommand, shell=True) and keep my job
