Hello Fabian, 

We have noticed that the log destination option in the radsecproxy configuration file is completely ignored when radsecproxy is made to run in the foreground with the -f argument. Looking at the code ( snippet pasted below ), it looks to be something intentional.

In radsecproxy.c
radsecproxy_main() 
{
////
    if (!foreground) {
        debug_set_destination(options.logdestination
                              ? options.logdestination
                              : "x-syslog:///", LOG_TYPE_DEBUG);
        if (options.ftickssyslogfacility) {
            debug_set_destination(options.ftickssyslogfacility,
                                  LOG_TYPE_FTICKS);
            free(options.ftickssyslogfacility);
        }
    }
}

However, we think that if the configuration file has a log destination, it should override any other directive and we should write logs to that log destination instead of using -f as a toggle to write to STDOUT vs the log destination. Let us know what you think about this ?

Here is my suggested fix , change the above snippet of code to:-

    if (options.logdestination) {
        debug_set_destination(options.logdestination, LOG_TYPE_DEBUG);
        free(options.logdestination);
    } else if (!foreground) {
        debug_set_destination("x-syslog:///", LOG_TYPE_DEBUG);
    }

    if (options.ftickssyslogfacility) {
        debug_set_destination(options.ftickssyslogfacility,
                              LOG_TYPE_FTICKS);
        free(options.ftickssyslogfacility);
    }


Thanks,
