NAME

       rlprd - remote printing proxy daemon

SYNOPSIS

       rlprd  [-nqV] [-pport] [-ttimeout] [--debug]

DESCRIPTION

       rlprd  is a proxy which runs between the remote printing commands (rlpr(1), rlpq(1), and rlprm(1)) and standard lpd print servers in situa-
       tions where the remote printing commands cannot be installed setuid root.  For a discussion on how to configure the  remote  printing  com-
       mands, please see rlpr(1).

       rlprd needs to be installed setuid root - if it cannot be run this way, it is useless.

       rlprd  works by mapping non-privileged port requests from rlpr(1) clients to privileged ports so that lpd's will listen to them.  Eliminat-
       ing the "security" gained by having privileged ports is a non-issue, since the Internet is no longer just Unix, and Unix  is  the  only	OS
       that has the privileged port concept.

       rlprd  is  not  a  replacement for lpd(8).  It merely passes data to a lpd(8) on a target machine (which is specified by an invocation of a
       remote printing command).  However, when a client is using the rlpr suite of tools to do remote printing, the client does not need  to  run
       an lpd(8) locally.

       Note  that once an rlprd is set up on a network (including the Internet), any host may connect to it and use its proxy services if it knows
       the name of the machine running it.

OPTIONS

       --debug
	      Print gobs of debugging information.

       -n, --no-daemon
	      Don't run rlprd as a daemon.  Usually not needed.

       -p, --port=number
	      Select an alternate port (instead of 7290) to listen on.	Usually not needed.

       -q, --quiet, --silent
	      Quiet mode - stay quiet (except for fatal errors).

       -t --timeout=seconds
	      Set the inactivity timer.  If the connection hangs for more than seconds seconds, then rlprd will time out the connection.  Use  the
	      special value `-1' to wait forever.  Default timeout is 3 seconds.

       -V, --version
	      Print version and exit.
