Hi
AAAA record should be used first if present. But if there's an a A and AAAA then both should be used too
I sort of agree, but that would break any existing implementations where the home_server has A and AAAA records but is not listening on it's V6 address, so it's really not a good idea.
, ie in client or proxy mode - we have dual stack and gave both v6 and v4 defined to give us routing resiliency
If you want this behaviour then define a v4 and v6 home server and use ipv4addr and ipv6addr, that's exactly the sort of scenario they were added for.
Else the server would have to add both, then go through a vetting process to figure out whether there's a server listening on both the v4 and v6 addresses.
The logic we have here may not be the same for things like dynamic home servers/dynamic discovery. There's a very big difference between the system administrator hard coding the addresses of servers, and FreeRADIUS having to discover the state of the world from a realm.
Also... if the address doesn't resolve the server fails to start? Ouch. Very nasty behaviour -1
You've specified a remote resource which doesn't exist. It's the same with the connection pool, if it can't establish 'start' connections for a pool the server fails to start.
And to quote from the clients.conf file which has been shipped with the server for many years: # # A note on DNS: We STRONGLY recommend using IP addresses # rather than host names. Using host names means that the # server will do DNS lookups when it starts, making it # dependent on DNS. i.e. If anything goes wrong with DNS, # the server won't start! # # The server also looks up the IP address from DNS once, and # only once, when it starts. If the DNS record is later # updated, the server WILL NOT see that update. # -Arran Arran Cudbard-Bell <a.cudbardb@freeradius.org> FreeRADIUS Development Team FD31 3077 42EC 7FCD 32FE 5EE2 56CF 27F9 30A8 CAA2
