FreeRADIUS 没有收到任何请求

Question

I configured FreeRadius to use MySQL and everything was working until a while ago, when some teammates complained they cannot authenticate to the server.

So I started FreeRadius again in debug mode and I tried with the radtest testing password 127.0.0.1 0 testing123 classic testing, but I receive No reply from server for ID 241 socket 3 .

Actually it seems that the server doesn't receive anything since in the log I just can see Ready to process requests message, when I run the radtest.

From the output of the debug mode, it seems Free Radius is listening

radiusd: #### Opening IP addresses and Ports ####
listen {
        type = "auth"
        ipaddr = *
        port = 1813
   limit {
        max_connections = 16
        lifetime = 0
        idle_timeout = 30
   }
}
listen {
        type = "acct"
        ipaddr = *
        port = 1814
   limit {
        max_connections = 16
        lifetime = 0
        idle_timeout = 30
   }
}
listen {
        type = "auth"
        ipv6addr = ::
        port = 1813
   limit {
        max_connections = 16
        lifetime = 0
        idle_timeout = 30
   }
}
listen {
        type = "acct"
        ipv6addr = ::
        port = 1814
   limit {
        max_connections = 16
        lifetime = 0
        idle_timeout = 30
   }
}
listen {
        type = "auth"
        ipaddr = 127.0.0.1
        port = 18120
}
Listening on auth address * port 1813 bound to server default
Listening on acct address * port 1814 bound to server default
Listening on auth address :: port 1813 bound to server default
Listening on acct address :: port 1814 bound to server default
Listening on auth address 127.0.0.1 port 18120 bound to server inner-tunnel
Listening on proxy address * port 36889
Listening on proxy address :: port 48860

and also the client configuration seems correct to me

client localhost {
        ipaddr = 127.0.0.1
        proto = *
        secret = testing123
#       shortname = localhost
        nas_type         = other        # localhost isn't usually a NAS...        
        limit {
                
                max_connections = 16
                lifetime = 0
                idle_timeout = 30
        }
}

Can you help me to debug why it doesn't work anymore?

Answer 1

You have changed the ports in the configuration. Auth should be on port 1812, and acct on 1813, not 1813 and 1814 as you currently have.
