5.1 Run-Time Configuration Options -- `raddb/config'

At startup radiusd obtains its configuration values from three places. The basic configuration is kept in the executable module itself. These values are overridden by those obtained from `raddb/config' file. Finally, the options obtained from the command line override the first two sets of options.

When re-reading of the configuration is initiated either by SIGHUP signal or by SNMP channel any changes in the config file take precedence over command line arguments, since `raddb/config' is the only way to change configuration of the running program.

This chapter discusses the `raddb/config' file in detail.

The `raddb/config' consists of statements and comments. Statements end with a semicolon. Many statements contain a block of sub-statements which also terminate with a semicolon.

Comments can be written in shell, C, or C++ constructs, i.e. any of the following represent a valid comment:

# A shell comment /* A C-style * multi-line comment */ // A C++-style comment

These are the basic statements:

5.1.1 option block		Option block: set the global program options.
5.1.2 logging block		Fine-tune the logging.
5.1.3 auth statement		Configure authentication service.
5.1.4 acct statement		Configure accounting service.
