how to radtest from another client

I install freeradius in the server its ip is  192.168.1.1. In the server  I have already do the radtest ,and the result is OK rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=11, length=20  I want to add a test authenticator host client. So I add something at the end of my clients.conf and assign a shared-secret.  client 192.168.1.100 {      secret = testing123      shortname = 192.168.1.100   } Should I do other things to finish it?  I need to do the radtest in the client(192.168.1.100)  right? But there isn't a radtest command in the client, Need I install some softwares in the client? thank you for your help ,best regards.
