Click Configuration

[roy]

Hi,

I would like to build denial-service-router using IPRateMonitor. But
encounter this message:

#cat /proc/click/errors:
line 14: can't reuse `rm0 :: IPRateMonitor' push output 0
line 34: `b1 :: CompareBlock' input 0 unused
line 14: `rm0 :: IPRateMonitor' output 1 unused
Router could not be initialized!

The configuration file as below:

      2 // eth0 172.17.16.113 00:C0:4F:18:B0:F2
