Use the couter module it does exactly what you want without triggers etc. Regards Jaco van Tonder ________________________________________ From: freeradius-users-bounces@lists.freeradius.org [mailto:freeradius-users-bounces@lists.freeradius.org] On Behalf Of sagar.patil@bt.com Sent: 17 August 2005 11:28 AM To: freeradius-users@lists.freeradius.org Subject: How to Disable RADIUS user logins if 'Session-Timeout' falls below 0 Hi All, I am using FreeRadius with PostgreSQL and everything is running like a charm besides a small issue. I am using session-timeout attribute in radreply table to control user session time. I have added a trigger on RADACCT table which subtracts amount of time used by user from RADREPLY each time when he logs in. It does work but when time is below 0 or negative I need to stop user from getting into my system and I am failing to do so. Here are my RADREPLY Table entries INSERT INTO radreply (id, username, attribute, op, value) VALUES (2, 'sagar', 'Idle-Timeout', ':=', '300'); INSERT INTO radreply (id, username, attribute, op, value) VALUES (3, 'sagar', 'Reply-Message', ':=', 'You Have Logged in Successfully'); INSERT INTO radreply (id, username, attribute, op, value) VALUES (1, 'sagar', 'Acct-Interim-Interval', ':=', '120'); INSERT INTO radreply (id, username, attribute, op, value) VALUES (4, 'sagar', 'Session-Timeout', ':=', '-904'); The easiest way would be altering Authenticate SQL and adding a condition to check Session-Timeout to see it doesnt fall below 0 I am not very good in POSTGRES so can someone please let me know how to do it. The other way would be using a Function /Procedure to carry out this check but my question is how to use procedures/functions in postgres.conf authenticate_query = "SELECT Value,Attribute FROM ${authcheck_table} \ WHERE UserName = '%{User-Name}' AND ( Attribute = 'User-Password' OR Attribute = 'Crypt-Password' ) \ ORDER BY Attribute DESC" Sagar Patil British Telecommunications plc Registered office: 81 Newgate Street London EC1A 7AJ Registered in England no. 1800000.
