Ok in fact it's a user that send this request without password.
Usually we reject well bad password. But each time this user is trying to access, the freeradius stop receiving any request !!
We need to reboot the freeradius. I have replace the realusername of the user for VALIDUSERNAME.
On the radius.log I see nothing about this access-request, I need to run the freeradius with -X option and checking the log.
What could be wrong with this user and How can I prevent the radiusd to crash ?
Thanks in advance
Log details follow 3 request 3 crash ...
