radsqlrelay - Man Page

relay SQL queries to a central database server


radsqlrelay [-?] [-d sql_driver] [-b database] [-f file] [-h host] [-u user] [-P port] [-p password] [-1] [-x] file_path


radsqlrelay tails a SQL logfile and forwards the queries to a database server. Used to replicate accounting records to one (central) database, even if the database has extended downtime.

The SQL logfile is created by the rlm_sql module with the rlm_sql_null driver logging to disk.. The module must be configured in the radiusd server before you can use radsqlrelay.
