This has been developed in order to provide diagnostic and status information for databases that need to keep track of job progress through a spool queue. The LPC status command is used to show the status of the queues currently being managed by the LPRng server. Note that this form of the command is supported only by LPRng, and is not backwards compatible with BSD LPR implementations. In order to do this, the following functionality is provided with LPRng. Host is the destination host, and can be a name or IP address.
Port is the port on the destination host.
Each log message reports a system event or status change of the LPD server. When the connection is first established, a complete dump of the status of the LPD server is sent. After this, only status update messages are sent. The remote monitor can force a status dump by simply closing and reopening the connection. Each message is encoded as a URI escaped string.
