Re: Iperf 1.7.0 UDP problem

[Gregory G. <ggo...@uf...>]

If you do something like:

iperf -p 5005 -b 512k -u -c host

you'll get a warning message that says:

WARNING: option -b implies udp testing
WARNING: option -b is not valid for server mode

Try reversing the syntax as follows, and things should work:

iperf -c host -p 5005 -b 512k -u

(I could be completely off, but I've seen this behavior before.)

Cheers, -g
