RE: freeradius is not loading clients

8 Jan 2024

      Sure you edited the right file? 
/etc/raddb/clients.conf

See: https://github.com/FreeRADIUS/freeradius-server/blob/master/raddb/clients.co...

I think you need to add "client" in front of your client names.
Like:
"client Switch_96 {"

Peace,
here is the content of the clients file:

Switch_96 {
         ipaddr                             = 10.16.10.252
         secret                              = kawabanga
         require_message_authenticator     = no
         nastype                         = cisco
         }

SkoriniSwitch_1st {
         ipaddr                             = 10.16.10.241
         secret                              = kawabanga
