WIFI Controller C5210 - "Unable to connect to RADIUS servers"

[Kombe_Kaponda]

Greetings,

We are using an extremE controller C5210 with WS-AP3715I Access Points and are getting a "Unable to connect to RADIUS servers" when ever we want to connect.

We have rebooted the radius server and the controller to NO avail.

Any pointers?

Thanks,
Kombe

Still struggling with this issue. Suspect certificate. On the DC when I hit edit on that I just get:
Cannot configure EAP
A certificate could not be found that can be used with this Extensible Authentication Protocol

make sure radius isn't running, from a command prompt, with root access run Radius in Debug mode to see exactly what is not working.

root@localhost:~# freeradius -XX

once executed, it will show you the details of all the modules and configuration as it loads and gets ready to run.

The RADIUS server log look like below. how do i deal with the log:

Marking home server 10.1.0.60 port 1812 as zombie (it looks like it is dead).

I can Ping 10.1.0.60?

Yes but it depends on the flavour of linux that you are running, ubuntu is like this:

root@kubuntu-1:/home/gareth# /etc/init.d/freeradius restart
[ ok ] Restarting freeradius (via systemctl): freeradius.service.

Check the pid has changed by running this before/after the above:

root@kubuntu-1:/home/gareth# ps aux|grep rad
freerad 16437 0.0 0.4 126196 6944 ? Ssl 13:39 0:00 /usr/sbin/freeradius

Is their a way to restart Linux RADIUS service?
