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.

Hi all:
I try to run the bwctl tool from the command line, I set the "bwctl - s <server IP>" in client, but the client window
shown the message "bwctl: 25 seconds until test results available
RECEIVER START
bwctl: Remote 'sender' never initiated handshake - canceling
RECEIVER END
"
What's the problem? How can I use bwctl's tool(iperf) to run in the command
line ?

Best regards,

Vicky
