(RADIATOR) unknown ports

[Ronan Eckelberry]

	Most likely those ports are opened to communicate with the other
RADIUS and/or SQL servers that you are proxying to.  Do a netstat to see
what addresses that they are connected to.  You will probably see that
it is the other servers.  RADIUS RECEIVES Authentication and Accounting
requests on 1645 and 1646 (Or whatever ports you configure in your cfg
file), but for it to proxy the info, it will have to open up another
connection on another port to connect to the other RADIUS servers.  You
will probably see that they are connecting to another address on port
1645 or 1646.

Subject: (RADIATOR) unknown ports


I use Radiator 2.18.3.  I noticed that the server binds to three UDP
ports that aren't listed in my configuration, and appear to have random
port numbers (all greater than 1024).  I am using both the
authentication and accounting features, and I use <AuthBy RADIUS> to
proxy authentication requests.  In the current incarnation of the
daemon, it is bound to 1645 and 1646 (which is expected because I use
those for authentication and accounting) and also 2837, 2789, and 1443. 
It seems that there are always three ports, but the port numbers change
over time (it takes perhaps a day to notice a change).  Is this a normal
part of a radius server and/or a normal part of Radiator?  It seems a
bit strange to me that the server is bound to ports that don't appear to
be in use.
