NAME

     lpd -- line printer spooler daemon


SYNOPSIS

     lpd [-cdlpsW46] [port#]


DESCRIPTION

     The lpd utility is the line printer daemon (spool area handler) and is
     normally invoked at boot time from the rc(8) file.  It makes a single
     pass through the printcap(5) file to find out about the existing printers
     and prints any files left after a crash.  It then uses the system calls
     listen(2) and accept(2) to receive requests to print files in the queue,
     transfer files to the spooling area, display the queue, or remove jobs
     from the queue.  In each case, it forks a child to handle the request so
     the parent can continue to listen for more requests.

     Available options:

     -c      By default, if some remote host has a connection error while try-
	     ing to send a print request to lpd on a local host, lpd will only
	     send error message to that remote host.  The -c flag causes lpd
	     to also log all of those connection errors via syslog(3).

     -d      Turn on SO_DEBUG on the Internet listening socket (see
	     setsockopt(2)).

     -l      The -l flag causes lpd to log valid requests received from the
	     network.  This can be useful for debugging purposes.

     -p      The -p flag is a synonym for the -s flag.	It is being depre-
	     cated, and may be removed in a future version of lpd.

     -s      The -s (secure) flag causes lpd not to open an Internet listening
	     socket.  This means that lpd will not accept any connections from
	     any remote hosts, although it will still accept print requests
	     from all local users.

     -W      By default, the lpd daemon will only accept connections which
	     originate from a reserved-port (<1024) on the remote host.  The
	     -W flag causes lpd to accept connections coming from any port.
	     This is can be useful when you want to accept print jobs from
	     certain implementations of lpr written for Windows.

     -4      Inet only.

     -6      Inet6 only.

     -46     Inet and inet6 (default).

     port#   The Internet port number used to rendezvous with other processes
	     is normally obtained with getservbyname(3) but can be changed
	     with the port# argument.

     Access control is provided by two means.  First, all requests must come
     from one of the machines listed in the file /etc/hosts.equiv or
     /etc/hosts.lpd.  Second, if the rs capability is specified in the
     printcap(5) entry for the printer being accessed, lpr requests will only
     tory for files beginning with cf.	Lines in each cf file specify files to
     be printed or non-printing actions to be performed.  Each such line
     begins with a key character to specify what to do with the remainder of
     the line.

     J	     Job Name.	String to be used for the job name on the burst page.

     C	     Classification.  String to be used for the classification line on
	     the burst page.

     L	     Literal.  The line contains identification info from the password
	     file and causes the banner page to be printed.

     T	     Title.  String to be used as the title for pr(1).

     H	     Host Name.  Name of the machine where lpr(1) was invoked.

     P	     Person.  Login name of the person who invoked lpr(1).  This is
	     used to verify ownership by lprm(1).

     M	     Send mail to the specified user when the current print job com-
	     pletes.

     f	     Formatted File.  Name of a file to print which is already format-
	     ted.

     l	     Like ``f'' but passes control characters and does not make page
	     breaks.

     p	     Name of a file to print using pr(1) as a filter.

     t	     Troff File.  The file contains troff(1) output (cat phototypeset-
	     ter commands).

     n	     Ditroff File.  The file contains device independent troff output.

     r	     DVI File.	The file contains Tex l output DVI format from Stan-
	     ford.

     g	     Graph File.  The file contains data produced by plot(3).

     c	     Cifplot File.  The file contains data produced by cifplot.

     v	     The file contains a raster image.

     r	     The file contains text data with FORTRAN carriage control charac-
	     ters.

     1	     Troff Font R.  Name of the font file to use instead of the
	     default.

     2	     Troff Font I.  Name of the font file to use instead of the
	     default.

     3	     Troff Font B.  Name of the font file to use instead of the
	     default.

     4	     Troff Font S.  Name of the font file to use instead of the
     U	     Unlink.  Name of file to remove upon completion of printing.

     N	     File name.  The name of the file which is being printed, or a
	     blank for the standard input (when lpr(1) is invoked in a pipe-
	     line).

     Z	     Locale.  String to be used as the locale for pr(1).

     If a file cannot be opened, a message will be logged via syslog(3) using
     the LOG_LPR facility.  The lpd utility will try up to 20 times to reopen
     a file it expects to be there, after which it will skip the file to be
     printed.

     The lpd utility uses flock(2) to provide exclusive access to the lock
     file and to prevent multiple daemons from becoming active simultaneously.
     If the daemon should be killed or die unexpectedly, the lock file need
     not be removed.  The lock file is kept in a readable ASCII form and con-
     tains two lines.  The first is the process id of the daemon and the sec-
     ond is the control file name of the current job being printed.  The sec-
     ond line is updated to reflect the current status of lpd for the programs
     lpq(1) and lprm(1).
