Error binding to port for 0.0.0.0 port 1812

Hi Alan,
 
 I've installed FreeRadius-2.0.4 and I got some error saying
 ERROR: Failed to open socket:
 /usr/local/etc/raddb/radiusd.conf[210]: Error binding to port for 0.0.0.0 port 1812
 
 but when I check in radiusd.conf
 ipaddr    = *
 # interface = eth0 
 
 How can I fix this error?
 I have 2 ethernet cards, eth1 = 192.168.1.10 (DNS & iptables), eth0 = 192.168.0.10 (Wifi)
 
 Here a few thing that I'd edited:
 
 (uncomment)
 clients.conf 
 client 192.168.0.0/24
     secret          = testing123-1
     shortname     = private-network-1
 
 users
 add 
 MarsindNet        ClearText-Password    := "testing123"
                         Reply-Message      := "Hello, %{User-Name}"
 
 eap.conf
 
 eap {
            default_eap_type = tls
 }
  tls {
 .....
 fragment_size    = 1024
 include_length     = yes
 }
 
 Next step I want to test Windows XP client but I couldn't find 
 root.der & cert-clt.p12 as previous version have.
