11.3 radzap

radzap searches the Radius accounting database for matching login records and closes them.

At least one of the options ‘-n’, ‘-p’, or the user name must be specified. If they are used in conjunction, they are taken as if joined by the logical AND operation.

radzap operates in two modes: silent and confirm. The silent mode is enabled by default. When run in this mode, radzap deletes every record that matches the search conditions given.

In confirm mode radzap will ask for a confirmation before zapping each matching record. Any line beginning with a ‘y’ is taken as a positive response; any other line is taken as a negative response.

The confirm mode is toggled by the command line option ‘-c’.
