clients linux to freeradius

Hello. How do I do for that my clients linux (fedora core 4) soliciten autenticarse ante el servidor freeradius antes de conectarse a la red. Should I install an additional program for my client lunix asking for authentication?. Or is only necessary in some file modoficacion sde linux, as I did in Windows.
