[Sudarshan Soma]

(echo 'User-Name="userX"'; echo 'CHAP-Password="secretpass"') |
/usr/local/bin/radclient -x 192.168.11.94:1812 auth testing123
Sending Access-Request of id 85 to 192.168.11.94 port 1812
        User-Name = "userX"
        CHAP-Password = 0x5514442c350a2fbb54e47ee2d499a3bcfe
rad_recv: Access-Accept packet from host 192.168.11.94:1812, id=85, length=20
