RE: Freeradius proxy times out after 14 seconds

30 May 2023

      Hey Alan,

To exclude my company OS hardening influence to Freeradius behaviour I
downloaded and installed Untuntu 22.04.2 Server.
Freeradius install (apt install freeradius) was done right after clean OS
install.

Only changes done to Freeradius config were adding following snippets fo
clients and proxy conf files.

clients.conf
client example.org {
	ipaddr	= 203.0.113.1
	secret	= secret123
}

proxy.conf
realm example.org {
	authhost = 203.0.113.5
	secret = secret123
	nostrip
}

Testing with NTRadPing.
Authhost 203.0.113.5 don't exist so there is no reply expected.
This gives good indication how long Freeradius waits if no answer.

Exactly same result.
After 14 seconds I get reject back.

Any other ideas where to look at?

...
There's nothing in the configuration which sets that to 14 seconds.  The
default is 30 seconds.  The default is also to limit response_window to
max_request_time.
...
My guess is that you've changed the configuration to set max_request_time
= 14.
...
Either that, or you've changed the client configuration to set
response_window = 14
...
The simple thing to do here is read the debug output, and look for "14".
That's where the value of "14" is being set.
