Freeradius Testing

["Fernando Prince" <prince.fer@gmail.com>]

I am using freeradius_1.1.3 i want to test the capacity of it.  For that i m using radclient tool to measure the capacity.  I want to test how much request per second radius is capable to handle  for that i m firing the below mention command.  

 echo "User-Name = 10001@10.0.0.1", "CHAP-Password = 1234" | radclient 10.0.0.2  auth test123

But when i m using -n option with radclient it is giving me below error

# echo "User-Name = 10001@10.0.0.1", "CHAP-Password = 1234" | radclient -n 10  10.0.0.2  auth test123
