NAME

rlpdaemon − remote spooling line printer daemon, message write daemon

SYNOPSIS

/usr/sbin/rlpdaemon [−i] [−l] [−L logfile]

DESCRIPTION

rlpdaemon is a line printer 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, or removes jobs from 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).

−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 conditions from 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

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.
