Configuration doubt

[Osvaldohp]

Hi all.
I'd like some help to configure my Radius
server. My Radius authenticates users from my HotSpot to access the
internet.
I want to limit the uses to access the Internet, i did try Session-Timeout
attribute but don't work so far.

This is my users file:
mike  Auth-Type = System, User-Password == mike"
          Session-Timeout := 3600,

What i am doing wrong?
Can anyone help me with this task?
Thanks
