don't worry for radutmp... 

In your site-available/default,  explain sql for simultaneous is more faster.. so . i change it.. 

and i test it with radclient again.. doing

auth - acct start - (auth for check) - and acct stop to finish session test

output

tony@hp-pavilion6:~/backup_server/AAA/RADIUS$ ./test-radclient.sh 
Received response ID 12, code 2, length = 68

as I said,

%{%{Stripped-User-Name}:-%{%{User-Name}:-DEFAULT}}

is the default entry and works. it stops the deprecated message.   your original
which you were told to fix was very wrong. have a close look, they are different.

and are you calling the correct modules to ensure that the radutmp file is used?


what does

radiusd -X

show?
