LPPD(8C)

NAME
lppd - lpp listen and dispatch daemon

SYNOPSIS
lppd [-d] [-s service-designator]
(under /etc/rc.local)

DESCRIPTION
The lppd server listens for lightweight presentation protocol connections which utilize TCP-backing. The server implements the protocol described in RFC1085.

Basically, the server listens on various TCP ports for connections, and immediately execs the appropriate program to enter the protocol and provide the service. The `-s' option overrides the default service-qualifier used when deciding which services to listen for.

Note that lppd does not listen for connections which utilize UDP-backing. To support this transport base, the program which implements the service must listen directly itself (and potentially manage multiple simultaneous associations). This is done trivially by using the “isodeserver()” routine.

DEBUG OPERATION
If lppd is started interactively, or if the `-d' switch is given, then debug mode is entered. In this case, all logging activity is displayed on the user's terminal, the logging information is more verbose, and lppd will terminate after it handles the first incoming connection (this allows lppd to be run under a debugger).
