Thanks Allan and Arran, the server is responding after i did a symbolic link as below.
Below is the command that i did. ln -sf /usr/local/etc/raddb/sites-available/dynamic-clients /usr/local/etc/raddb/sites-enabled/ Just a couple of doubts. 1) secret is required in the client definition (file: 192.168.169.74)? How do i make sure the server validate the client secret upon receiving the radius packet? Is the logic lies with dynamic_client_server? I noticed FreeRADIUS-Client-Secret was dynamically hard-coded in the example? Pardon me if i asked silly question. Within sites-available/dynamic-clients, client dynamic { ipaddr = 0.0.0.0 netmask = 0 dynamic_clients = dynamic_client_server directory = /usr/local/etc/raddb/dynamic-clients lifetime = 3600 } server dynamic_client_server { <example code> } Within raddb/dynamic-clients/192.168.169.74 client 192.168.169.74 { secret = secret123 } -- View this message in context: http://freeradius.1045715.n5.nabble.com/radmin-del-client-error-tp4725176p4733324.html Sent from the FreeRadius - User mailing list archive at Nabble.com. - List info/subscribe/unsubscribe?
