Dear everybody, I was asked to manaully add a user into our Radius db for some thrird party monitoring. Sometimes when I insert the row it's there, but after 5 mins or less the row is removed, as shown below. Does some Radius process remove rows? * First attempt * mysql> INSERT INTO radcheck (id, username, attribute, op, value) VALUES (DEFAULT,'xmonitor1','User-Password',':=','xxxxxxx'); Query OK, 1 row affected (0.01 sec) mysql> select * from radcheck where username = 'xmonitor1'; Empty set (0.01 sec) (Disappeared immediately!) * Try again * mysql> INSERT INTO radcheck (id, username, attribute, op, value) VALUES (DEFAULT,'xmonitor1','User-Password',':=','xxxxxxx'); Query OK, 1 row affected (0.00 sec) mysql> select * from radcheck where username = 'xmonitor1'; +-------+-----------+---------------+----+---------+ | id | username | attribute | op | value | +-------+-----------+---------------+----+---------+ | 65745 | xmonitor1 | User-Password | := | xxxxxxx | +-------+-----------+---------------+----+---------+ 1 row in set (0.00 sec) ( Now it's there) ( Let's wait 5 mins and try this query again ) mysql> select * from radcheck where username = 'xmonitor1'; Empty set (0.00 sec) ( Opps. now it's gone ) ( Let's see if some other entry took this id ) mysql> select * from radcheck where id = '65745'; Empty set (0.00 sec) mysql> select * from radcheck where id = 65745; Empty set (0.00 sec) ( Nope ). Operating System: CentOS 6.2 RADIUS Server: freeradius-mysql-2.1.12-1.el6.x86_64 freeradius-utils-2.1.12-1.el6.x86_64 freeradius-2.1.12-1.el6.x86_64 MYSQL server: percona-xtrabackup-2.2.9-5067.el6.x86_64 Percona-Server-shared-56-5.6.21-rel69.0.el6.x86_64 Percona-Server-server-56-5.6.21-rel69.0.el6.x86_64 Percona-Server-shared-compat-5.5.30-rel30.2.508.rhel6.x86_64 percona-toolkit-2.2.3-1.noarch Percona-Server-client-56-5.6.21-rel69.0.el6.x86_64 I'd be very grateful if somebody could let me know how I could diagnose this, or perhaps tell me the right way to insert a username+password into Radius. Kind regards. Sophie
