It would be easier to help you if you actually showed the command you  
ran, and the error messages you saw - including syslog messages.

However I'll make my best guess: This message likely indicates a  
firewall issue. The bwctld <sender> attempts to contact the bwctld  
<receiver> process to exchange time stamp information, and to verify  
that the <receiver> really did want the test. (This is because all  
traffic up till now has been initiated by the client, and bwctl runs a  
bandwidth test between two servers.)

The port range that will be used, is defined by the 'sending' side of  
the test, and can be set using the peer_ports option in the  
bwctld.conf file on that system.
