Re: Iperf 1.7.0 UDP problem
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
