sensor can't communicate with console

["Paul Yang" <pyang () fporch com>]

Hello,
 
            I set up two 7.3 Linux machines with console and agent on
different boxes. Let's say that the Snort center is using IP 1.1.1.1.
 
            The other Linux machine is running snort sensor with two
interfaces. (eth0 on 1.1.1.2 and eth1 has no ip)
After I ran the "setup.sh" on the sensor and add a sensor on the
console, I get the following error on the "sensor message". 
 
Sensor message: unauthorized
A password is required to access this web server, please try again.
 
If I put a wrong password during the "setup" script, how can I erase it
and rerun the setup?
 
Any advice or pointer will be great help?
 
Thanks,
 
Paul
