Add the following line to the \fBinetd.conf\fR file to enable the \fBcups-lpd\fR daemon: .br .nf printer stream tcp nowait lp /usr/lib/cups/daemon/cups-lpd cups-lpd .fi .LP If you are using the newer \fIxinetd(8)\fR daemon, add the following lines to the \fBxinetd.conf\fR file: .br .nf service printer { socket_type = stream protocol = tcp wait = no user = lp server = /usr/lib/cups/daemon/cups-lpd } .fi .SH SECURITY \fBcups-lpd\fR currently does not perform any access control based on the settings in \fIcupsd.conf(5)\fR or in the \fIhosts.allow(5)\fR or \fIhosts.deny\fR files used by TCP wrappers. Therefore, running \fBcups-lpd\fR on your server will allow any computer on your network (and perhaps the entire Internet) to print to your server. .LP While \fIxinetd\fR has built-in access control support, you should use the TCP wrappers package with \fIinetd\fR to limit access to only those computers that should be able to print through your server. .SH OPTIONS The \fI-o\fR option to \fBcups-lpd\fR inserts options for all print queues. Most often this is used to disable the "l" filter so that remote print jobs are filtered as needed for printing: .br .nf printer stream tcp nowait lp /usr/lib/cups/daemon/cups-lpd cups-lpd \ -o document-format=application/octet-stream server = /usr/lib/cups/daemon/cups-lpd server_args = -o document-format=application/octet-stream .fi .LP The example shown resets the document format to be \fIapplication/octet-stream\fR, which forces auto-detection of the print file type. .SH COMPATIBILITY \fBcups-lpd\fR does not enforce the restricted source port number specified in RFC 1179, as using restricted ports does not prevent determined users from submitting print jobs. While this behavior is different than standard Berkeley LPD implementations, it should not affect normal client operations. .LP The output of the status requests follows RFC 2569, Mapping between LPD and IPP Protocols. Since many LPD implementations stray from this definition, remote status reporting to LPD clients may be unreliable. .SH SEE ALSO inetd(8), xinetd(8), CUPS Software Administrators Manual, http://localhost:631/documentation.html .SH COPYRIGHT Copyright 1993-2002 by Easy Software Products, All Rights Reserved. .\" .\" End of "$Id: cups-lpd.man,v 1.3 2002/04/09 00:14:37 jlovell Exp $". .\"
