Usage

The freeDiameter daemon (freeDiameterd) accepts the following command-line arguments. Note that all parameters are optional, but a configuration file is required by the framework. If not provided on the command-line, the configuration file will be searched in a default location as shown bellow.

-h or --help

Displays this usage and exits.

-V or --version

Displays the version of the daemon and exits.

-c /path/to/conf or --config=path/to/conf

Use the /path/to/conf configuration file instead of ${DEFAULT_CONF_PATH}/freeDiameter.conf (use -h to see what the default prefix is).

-d, -q, --debug or --quiet

Increases or decreases the verbosity of the debug messages. The flags can be specified several times. See Troubleshooting page for more information.

The additional command-line options bellow are also available, but only if the daemon has been compiled in the "Debug" configuration (-DCMAKE_BUILD_TYPE:STRING=Debug):

-f funcname or --dbg_func=funcname

The debug level will be set to maximum only inside functions with the name funcname. Since this is dynamically evaluated, it works even with static functions and extension functions (that use debug macro from the library). It slows the framework execution, so do not use it when not needed. To get detailed information about the handling of incoming messages, you might use for example:

$ freeDiameterd --dbg_func=msg_rt_in

-F filename or --dbg_file=filename

Same as previous one, but all functions from the file filename will be logged at maximum trace level. Only the basename is compared, ignoring the path, as follow:

$ freeDiameterd --dbg_file=app_acct.c

At the moment, all debug messages from the freeDiameter daemon are sent to stdout. If you want to capture them in a file, you should redirect the stream as follow:

$ freeDiameterd -dd > ~/fD.log 2>&1

Or, using the command tee:

$ freeDiameterd -dd 2>&1 | tee -i ~/fD.log
