RE: Iperf 2.0 Beta
Yeah supply (-1) at the command line and you should get the single
connection bit. The clients will just error and quit so there is no try
again functionality built in on that end to assist with the feature. The
lack of references to the option is due to the beta status. =-)

I seem to recall such a feature being mentioned, but cannot find the reference. Also is there any logging of who connects, when and for what? The idea is to have a complimentary iperf server running all the time, but to only allow one connection at a time (not sure how the client would know to try again later).
