Failed binding to authentication address

[Federico Olivieri]

Hi All,

I know that this topics has been discussed many times but all
solution/answers found on the mailing list didn't work for me (sure that is
my fault!)

When I stop the service and I run freeradius -xxx the message is:

Thu Nov 26 15:14:25 2015 : Info:  ... adding new socket proxy address *
port 47256
Thu Nov 26 15:14:25 2015 : Debug: Listening on authentication address *
port 1812
Thu Nov 26 15:14:25 2015 : Debug: Listening on accounting address * port

Thu Nov 26 15:14:25 2015 : Debug: Listening on proxy address * port 1814
Thu Nov 26 15:14:25 2015 : Info: Ready to process requests.

then, I start radius and when I try to do radtest I get this error:

root at raspberrypi:~# /etc/init.d/freeradius start
[ ok ] Starting FreeRADIUS daemon: freeradius.
root at raspberrypi:~# radtest "John Doe" hello 127.0.0.1 0 testing123

        User-Name = "John Doe"
        User-Password = "hello"
        NAS-IP-Address = 127.0.1.1
        NAS-Port = 0
        Message-Authenticator = 0x00000000000000000000000000000000
rad_recv: Access-Reject packet from host 127.0.0.1 port 1812, id=126,
length=20

Looking into a second debug I can see:

Thu Nov 26 15:15:06 2015 : Debug: radiusd: #### Opening IP addresses and
Ports ####
Thu Nov 26 15:15:06 2015 : Debug: listen {

Thu Nov 26 15:15:06 2015 : Debug:       ipaddr = *
Thu Nov 26 15:15:06 2015 : Debug:       port = 0
Thu Nov 26 15:15:06 2015 : Error: Failed binding to authentication address
* port 1812: Address already in use
Thu Nov 26 15:15:06 2015 : Error: /etc/freeradius/radiusd.conf[240]: Error
binding to port for 0.0.0.0 port 1812

What I'm doing wrong? For me is normal that the port is 1812 is busy
because freeradius is using it!

Thanks!
