--syslog-name NAME (lt-qpidd): Name to use in syslog messages

--syslog-facility LOG_XXX (LOG_DAEMON): Facility to use in syslog messages

Daemon options:

-d [ --daemon ]: Run as a daemon. Logs to syslog by default in this mode.

--transport TRANSPORT (tcp): The transport for which to return the port

--pid-dir DIR (/home/cajus/.qpidd): Directory where port-specific PID file is stored

-w [ --wait ] SECONDS (600): Sets the maximum wait time to initialize the daemon. If the daemon fails to initialize, prints an error and returns 1

-c [ --check ]: Prints the daemon's process ID to stdout and returns 0 if the daemon is running, otherwise returns 1

-q [ --quit ]: Tells the daemon to shut down

Environment

QPID_<option>

There is an environment variable for each option.

The environment variable is the option name in uppercase, prefixed with QPID_ and '.' or '-' are replaced with '_'. Environment settings are over-ridden by command line settings. For example:

export QPID_PORT=6000
export QPID_MAX_CONNECTIONS=10
export QPID_LOG_TO_FILE=/tmp/qpidd.log

Files

/etc/qpidd.conf

Default configuration file.

Configuration file settings are over-ridden by command line or environment variable settings. '--config <file>' or 'export QPID_CONFIG=<file>' specifies an alternate file.

Each line is a name=value pair. Blank lines and lines beginning with # are ignored. For example:

# My qpidd configuration file.
port=6000
max-connections=10
log-to-file=/tmp/qpidd.log
