Hi Alan,

Thanks a lot for your help to explain this to me.

But I still have this puzzle inside my head :)
My scenario is that the client will do some
meassurement after it receive access_accept from
server. I think I can trigger this by writing shell
script when the packet access_accept received. (am i

Second question :
How do I learn to use the command line to run client?
I just using this command to send access_request for
user name Maria, 

# echo "User-Name = Maria, User-Password = testing" |
radclient auth testing123

How do I find other command to start and stop
I think I can use the same command like above just
change the auth become acct.
But the problem is how do i tell the server that I
want to stop the acct session?

I finally make progres so the server send this
access-Accept to the client.  

Sending Access-Accept of id 131 to
        Framed-Protocol = PPP
        Session-Timeout = 600
        Login-Service = Telnet
        Idle-Timeout = 360

But why the session-TImeout is not working? 
I already set this attributes in users file. seems no
sign that it works.
How do I see if the time already passed, the client
will be disconnected from server?

Sorry for long questions. I really apreciate if you
want to answer them.

Have a great weekend
