Dear Aaron-san,

This is the result.
I did downgrade to avoid this issue but I've upgraded again for 
the test. Still, I have same issue.


*Receiver
# /etc/init.d/iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]

# bwctl -V
Version: 1.5.2-5


*Sender
# /etc/init.d/iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]

# bwctl -V
Version: 1.5.2-5

# bwctl -c perf-sin -u -x
bwctl: Using tool: iperf
bwctl: 15 seconds until test results available

RECEIVER START
bwctl: Remote 'client' (Sender) never initiated handshake: listening at
port(6015) - canceling

RECEIVER END

SENDER START

SENDER END


Best Regards,
-Takatoshi Ikeda
