Radius and 4.3 - Fresh Install of Slave

I just recently installed a new Slave DC to my network and for some reason Radius doesn’t seem to be working. I have made sure to configure the clients.conf that is located under the 3.0 directory with the appropriate settings, but it doesn’t seem to be authenticating. I currently have two other slaves that are working fine, although those were upgraded from 4.2 to 4.3 so I am not sure what the issue could be. Any help would be greatly appreciated.


in general the FreeRadius daemon writes information to /var/log/freeradius/radius.log. Have you taken a look at it?

If that isn’t enough: the FreeRadius daemon provides quite a lot of useful debug output if you enable it:

  1. First, stop the running daemon (e.g. systemctl stop freeradius.service).
  2. Then start it manually with the -d option: freeradius -d -x
  3. Try authenticating with your device.

Again, the output will go to the aforementioned log file.

Kind regards,
