NAME
rlpdaemon - daemon for queuing, displaying, removing and altering remote spool requests and writing
remote messages
SYNOPSIS
/usr/sbin/rlpdaemon
[ -i ][-l
][-L logfile ]
DESCRIPTION
rlpdaemon is a LP daemon (spool area handler) for remote spool requests.
rlpdaemon is normally
invoked at boot time from the
/sbin/rc file or started by inetd(1M), when necessary.
rlpdaemon
runs on a system that receives requests to be printed.
rlpdaemon transfers files to the spooling area,
displays the queue, removes jobs from the queue, or alters jobs in the queue.
rlpdaemon is also used as a server process to write a message on the user’s terminal, upon receiving a
request from a remote system.
Options
-i Prevent
rlpdaemon from remaining after a request is processed. This is required if
rlpdaemon is started from inetd (1M). When rlpdaemon
is invoked with this option,
error messages and valid requests received from the network are logged to either
/var/adm/lp/lpd.log
or logfile specified with -L option.
-l Cause rlpdaemon to log error messages and valid requests received from the network to
the file /var/adm/lp/lpd.log
. This can be useful for debugging.
-L logfile Change the file used for writing error messages and valid requests received from the net-
work to the file /var/adm/lp/lpd.log
to logfile .
When
rlpdaemon is started by inetd (1M), access control is provided via the file
/var/adm/inetd.sec
to allow or prevent a host from making requests. When rlpdaemon is not
started by inetd (1M), all requests must come from one of the machines listed in the file
/etc/hosts.equiv
or /var/spool/lp/.rhosts. When /var/spool/lp/.rhosts
is used
for access, the user name should be
lp.
The following entry should exist in
/etc/services
for remote spooling:
printer 515/tcp spooler
Control File Processing
The
lp subsystem expects that the control file associated with each request contain the datafile line entry
(starting with a lower case letter) indicating the file to be printed, and an associated unlink datafile entry
(U entry). The actual filename (N entry) for this datafile line entry can be above or below the datafile line
entry. If multiple copies of a file has to be printed, for example n copies, then the datafile line entry
should be repeated n times in succession.
rlpdaemon may reorder or insert the U entries in the control
file such that the datafile line entry and the U entry will be in succession for each file to be printed.
EXAMPLES
To start
rlpdaemon from /sbin/rc, invoke the command:
/usr/sbin/rlpdaemon
To start rlpdaemon from inetd, the following line should be included in the file /etc/inetd.conf:
printer stream tcp nowait root /usr/sbin/rlpdaemon rlpdaemon -i
WARNINGS
If the remote system is the same as the local system and rlpdaemon was not started by inetd (1M), the
local system name must be included in file /etc/hosts.equiv.
