update-disconnect and originate-coa

[Antonios Kalkakos]

Hello all,

I am trying to figure out how to disconnect a user using the 
originate-coa and update disconnect{} using FreeRADIUS 3.0.21 on Debian 
11. Sorry if it seems a bit stupid, but I am really confused and 
frustrated...

Let's say that a user configured in user's file "testuser 
Cleartext-Password := "password", Login-Time := "Wk1000-1400"" should be 
disconnected after the permitted Login-Time has passed. I enabled and 
changed the contents of the originate-coa according to it's 
documentation, using the correct NAS IP address, secret etc and added 
the coa_server = coa under the appropriate NAS section in clients.conf.

According to my understanding FreeRADIUS should have generated coa 
messages to the NAS but it didn't do anything.

Is this the correct way to forcibly disconnect the user using 
originate-coa?

Sorry again if the following question may be a bit stupid, but what is 
the recommended place in the virtual server (except pre- or post-proxy) 
to put update coa{} or update disconnect{}?

Using radclient (cat packet.txt | radclient -x <nas ip address>:3799 
disconnect "secret"") with the Acct-Session-Id obtained from freeradius 
-X output and the NAS coa secret, the user was disconnected normally.

Thank you very much in advance,
