hello. currently, if you direct iperf to be in server mode, and to listen on a port that is already in use, or not available to you, iperf gives a warning, but it should be fatal.
$ iperf -s -p 80 bind failed: Permission denied ------------------------------------------------------------ Server listening on TCP port 80 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ $ iperf -v iperf version 2.0.4 (7 Apr 2008) pthreads The attached patch fixes this; iperf will now consider this a fatal error and exit, but the exit code is still wrong. $ ./iperf -s -p 80 bind failed: Permission denied $ echo $? 0 -- deny ip any any (4393649193 matches)
