# NAME
#   lpd.conf - configuration file for the LPRng line printer spooler system
#
# DESCRIPTION
#   The file lpd.conf is used to provide configuration information for the
#   LPRng Printer spooler system and defaults for printcap information.  Lead-
#   ing spaces on lines are ignored, and blank lines and lines whose first non-
#   blank character is a sharp (``#'') are ignored.  Trailing blanks and tabs
#   (whitespace) for an option value are deleted unless the last one is escaped
#   with a backslash (``\'').  All other lines specify parameters and should be
#   of the following form:
#        keyword
#        keyword@
#        keyword#value
#        keyword=value
#   Note that these values are the same format as printcap(5) values.  Values
#   in the configuration can contain host or machine dependent information; to
#   assist with this, the following escape sequences in the configuration
#   information are replaced as follows:
#
#   %h   the short form of the host name (i.e.- non fully qualified).
#
#   %H   the fully qualified host name.
#
#   %a   the abbreviated architecture name, sun4, sol2, hpux, aix, irix5, etc.
#        This value can be set using the architecture keyword in the configura-
#        tion file and is set to a default value at compile_time.
#
#   %P   the printer name from the printcap entry (see below).
#
#   %R   the remote printer name from the printcap entry.
#
#   %M   the remote host name from the printcap entry.  This is truncated to
#        the short host name.
#
#   For example, on host dickory.sdsu.edu, the strings short=%h long=%H arch=%a
#   would be expanded as short=dickory long=dickory.sdsu.edu arch=sun4 .
#
#   The P, R, and M tags are provided for use with combined configuration and
#   printcap information.	 These values are not expanded when the printcap
#   information is initially processed, and can be used only in a limited
#   number of printcap or other entries.	Currently only the printcap :sd:
#   (spool directory) and :forward_server: (forward server) entries use these.
#
# GENERAL CONFIGURATION PARAMETERS
#
#   Some of the following paramters take lists of files or directories.  Unless
#   otherwise explicitly stated, these lists can be separated by commas (,),
#   semicolons (;), or colons, (punctuation) and possibly tabs or spaces (whi-
#   tespace) as well.
#
#   Keyword names can use either underscores (_) or hyphens (-) in their names,
#   but the underscore is preferred.
#
# include (no default)
#   This can be used to include files into the lpd.conf file.  The include
#   file parameter can be a punctuation or whitespace separated list of
#   files; the files must have absolute pathnames and must be readable.
#
# ae (default: "jobend $H $n $P $k $b $t")
#   This specifies either a script or a filter to be invoked at the send
#   of a job for accounting purposes.  See as for the matching accounting
#   at start, and the printcap(5) and lpd(8) man pages for details.
#
# allow_getenv (default: "LPD_CONF")
#   This option specifies an enviorinment variable whose value is a confi-
#   guration file.  Use of this is restricted to test purposes, and SUID
#   ROOT client and server will not run when the variable is enabled.
#
# ar (default: yes)
#   See printcap(5) for details.
#
# architecture
#   The default value is set at compile time and can be overwritten with
#   this parameter.	The default value of this parameter is set at compile
#   time and it is used when expanding the special sequence %a in pathname
#   and filename strings in this config file.
#
# as (default: "jobstart $H $n $P $k $b $t")
#   See as.
#
# bk (default: no)
#   See printcap(5) for details.
#
# bk_filter_options
#   (default: "$P $w $l $x $y $F $c $L $i $J $C $0n $0h $-a") If the "bkf"
#   (backwards compatible filter) flags is set in the printcap entry and
#   the original filter specification does not have a `$` in it, this
#   option string is appended to a filter specification, and the string
#   expanded with values from the printcap information and job informa-
#   tion.  (see of_filter_options, filter_options, bk_filter_options,
#   bk_of_filter_options)
#
# bk_of_filter_options
#   (default: "$w $l $x $y") If the "bkf" (backwards compatible filter)
#   flags is set in the printcap entry and the original filter specifica-
#   tion does not have a `$` in it, this option string is appended to the
#   OF filter specification, and the string expanded with values from the
#   printcap information and job information.  (see of_filter_options,
#   filter_options, bk_filter_options, bk_of_filter_options)
#

##check_for_nonprintable

# check_for_nonprintable (default: "")
#   (Used by LPR) check f and p formats for non_printable characters
#   unless -b (binary) or -l (literal) command_line option is supplied.
#   Note that files containing HPGL or other printer control languages
#   would often be classed as ``non_printable''.
#
# client_auth_command (defaults: "")
#   The default authorization command for a client to use.
#
# connect_grace (default: 0 seconds)
#   The time to pause before opening a new connection to a printer.	This

#   The time to pause after a failed connection or open of the printing
#   device before attempting a new connection or open.
#
# connect_timeout (default: 10 (seconds))
#   The time to wait for a device open or connection to complete.  A zero
#   value is infinite timeout.
#
# retry_nolink (default: true)
#   When TRUE and the LPD server is printing or transfering a job, then an
#   indefinate number of attempts to connect to or open the IO device will
#   be made.

#   (default: UDP) specifies a default protocol for logger information.
#   See logger_destination for details.
#
# default_permission (default: ACCEPT)
#   Default permission for operations.

default_tmp_dir /usr/tmp

# default_tmp_dir (default: /tmp)
#   Directory for temporary files.
#
# domain_name (default: "")
#   This parameter is optional, and is appended to the hostname to make it

#   means, such as gethostbyname(3n).
#
# ff (default:
#   Formfeed string.
#

filter_ld_path ""

# filter_ld_path
#   (default: /lib:/usr/lib:/usr/5lib:/usr/ucblib) The value for the

#   on SunOS, Solaris and Linux.
#

# filter_options "$A $B $C $D $E $F $G $H $I $J $K $L $M $N $O $P $Q $R $S $T $U $V $W $X $Y $Z $a $b $c $d $e $f $g $h $i $j $k $l $m $n $o $p $q $r $s $t $u $v $w $x $y $z"
filter_options $C $F $H $J $L $P $Q $R $Z $a $b $c $d $e $f $h $i $j $k $l $m $n $p $r $s $t $w $x $y

# Note: If we made filter_options a single (quoted) string, then filters
# would get all options as a single argument, bracketed by underscores
# (e.g. '-L_psz_', because all 'funny' characters are replaced).

# filter_options
#   (default: "$C $F $H $J $L $P $Q $R $Z $a $c $d $e $f $h $i $j $k $l $n
#   $p $r $s $w $x $y $-a") If the "bkf" (backwards compatible filter)
#   flags is not set in the printcap entry and the original filter specif-
#   ication does not have a `$` in it, this option string is appended to a
#   filter specification, and the string expanded with values from the
#   printcap information and job information.  (see of_filter_options,
#   filter_options, bk_filter_options, bk_of_filter_options)
#
#   The options for the filter command line will be replaced by
#   appropriate values.  Specifications have the form $[0| ][-][']X.
#   The default option expansion has the form $X -> -X'value'; the
#   form $0X or $(space)X adds a space after the -X, i.e. $0X -> -X
#   'value'; the form $-X suppresses the -X, i.e. $-X -> 'value'; and
#   the form $'X' suppresses the quotes around the value.  Note that the
#   0,-, and ' can be combined. For example, $-'X -> value.
#   Seems that null values are not passed to the filter.
#   The options will be expanded as follows:
#   Key  Value
#   a	Accounting file (printcap 'af')
#   b	Job size, i.e. total data file size, in bytes
#   c	if binary (format 'l') expands to -c
#   d	Control directory
#   e	job data file
#   f	original print file name (== N)
#   h	hostname (== H)
#   i	indent (== I)
#   j	job number from control file name
#   k	Control file name
#   l	printcap Page length (pl) value
#   m	printcap Cost factor (co) value
#   n	user logname (== P, also == L??)
#   p	Remote Printer name for forwarded jobs (== P ??)
#   r	Remote Host name for forwarded jobs
#   s	printer Status file (ps) value
#   t	current time in simple format
#   w	printcap Page width (pw) value
#   x	printcap x dimension (px) value
#   y	printcap y dimension (py) value
#   C	class
#   F	data file format character
#   H	hostname
#   J	jobname
#   L	username (?)
#   P	Printer name
#   S	printcap Comment tag (cm) value
#   0-9	control file line starting with digit
#   A-Z	control file line starting with letter. These seem to be (in
# 	conflict with stuff above):
#   A	Job identifier controlled by the use_identifier variable.
#   C	Class String to be used for the class line on the burst page.
#   H	Host Name.  Name of the machine where lpr was invoked.
#   I	Indent.  The number of characters to indent the output by (in ascii).
#   J	Job Name.  String to be used for the job name on the burst page.
#   L	Banner user name.  Information for banner page.
#   P	Person.  Login name of the person who invoked lpr.  This is used to verify ownership by lprm.
#   M	Send mail to the specified user when the current print job completes.
#   N	File name.  The original name of a data file which is in the job.
#   T	Title.  String to be used as the title for pr(1) when the LPR -p option was specified.
#   U	Unlink.  Job file to remove when printing completed.
#   W	Width. The page width (in characters) to used for printing.
#   Z	zoptions. Options passed by lpr -Zzoptions.  These are passed to output filters to aid in printing.
#

filter_path /

# filter_path
#   (default: /bin:/usr/bin:/usr/ucb:/usr/sbin:/usr/etc:/etc) The value
#   for the environment variable PATH, both used to find filters and
#   passed on to filters run by lpd and lpr.
#

fix_bad_job yes
## The default for fix_bad_job seems to be 'no'.
## Need it to replace '~' by '_' in PC spool file names, or
## get errors like "bad job line 'NC:/SPOOL/~LP00045.TMP'".

# fix_bad_job (default: yes)
#   Fix a bad job file - usually by ignoring multiple U (unlink) entries,
#   badly formatted file names, or other common botches produced by vari-
#   ous PC based LPR clients.
#

force_poll yes

# force_poll (default: no)
#   Some software packages put print jobs directly into the spool queues.
#   The force_poll flag forces lpd to periodically poll spool queues look-
#   ing for jobs and no server.  The poll_time variable sets the interval
#   between polls.
#
# forward_auth (default use_auth value)
#   Server uses authentication when forwarding a command.  Only done if
#   the original command was authenticated.
#

## full_time yes

# full_time (default: no)
#   Use full time and date format in logging and error messages.
#
# fx (default: flp)
#   See printcap(5) for details.
#

group lprngd

# group (default "daemon")
#   The group to use for file ownership and process permissions.  Used
#   only by lpd; this can be the name of a group or a number.  All filters
#   will run as the specified group.	 Note that if the group value is 0,
#   then the real user group of the process at startup will be used.
#
# kerberos_keytab (default "/etc/lpd.keytab")
#   The keytab file to be used by the LPD server when using built-in ker-
#   beros authentication.  The keytab file should be owned by the LPD
#   server, and be readable/writable only by it (i.e. - 600 permissions).
#
# kerberos_life (default NULL)
#   The lifetime of a Kerberos ticket.  NULL selects the default lifetime.
#   Time should be specified using the standard Kerberos time representa-
#   tions.
#
# kerberos_renew (default NULL)
#   The renewal of a Kerberos ticket.  NULL selects a non-renewable
#   ticket.	Time should be specified using the standard Kerberos time
#   representations.
#
# kerberos_service (default "lpr")
#   The service name used to make requests to the LPD server when using
#   kerberos authentication.	 For example, if kerberos_service has the
#   value lpr, the server is on host alpha.com, and the kerberos domain is
#   ALPHA.COM, then the kerberos principal name would be:
#   lpr/alpha.com@ALPHA.COM.
#
# la (default: yes)
#   See printcap(5) for details.
#
# lf (default: log)
#   Name of the log file.
#
# lo (default: lock)
#   Name of the lock file.
#
# localhost
#   (default "localhost") The name of the localhost entry to be used for
#   the TCP/IP loopback interface.  The TCP/IP connection may originate
#   from the local host; use this name to check to see if the local host
#   address is in the IP address database, and use it as the origination
#   address for local connections.  This is done to avoid problems with
#   multi-homed hosts who originate connections from different interfaces.
#

lockfile /var/spool/LPRng/lpd.lock.%h

# lockfile (default: /var/spool/lpd/lpd.lock.%h)
#   The file used to indicate the presence of an lpd server running on the
#   host.
#

logfile /var/spool/LPRng/lpd.log

# logfile
#   (default: /var/spool/lpd/lpd.log.%h) The file that lpd initially logs
#   debugging and informational messages to. Individual printcap entries
#   can also specify log files for each printer.
#

##logger_destination siv%514,UDP
## We do not really want this: logs each file being printed,
## but is not very informative

# logger_destination
#   (default: "") This specifies a destination for logger information gen-
#   erated by the lpd server.  The formation of the destination specifica-
#   tion is host[%port][,(TCP|UDP)].	 For example, localhost%2001,UDP
#   would send logger information to the localhost IP address, on port
#   2001 using the UPD protocol.  The default port and protocol are set by
#   the default_logger_port and default_logger_protocol configuration
#   variables respectively.
#
# longnumber
#   (default: no) RFC1179 requires 3 digit job numbers; setting longnumber
#   to yes allows 6 digit numbers.  If the backwards_compatible flag is
#   set, only 3 digit numbers will be used.
#

##lpd_port 5515

# lpd_port (default: printer)
#   The port that lpd binds to, and that lpr and the other client programs
#   send their requests to.	If this is numeric and within the valid IP
#   port range, that port number is used; otherwise, a service lookup is
#   performed and the corresponding service port is used; see services(5).
#   This parameter is useful for debugging a new installation of LPRng, in
#   that running LPRng on a different port from the default will not
#   interfere with a previous installation of LPD or LPRng.
#

lpd_printcap_path /usr/sms/share/LPRng/etc/lpd_printcap

# lpd_printcap_path (default: "/etc/lpd_printcap:/usr/etc/lpd_printcap")
#   The location of additional lpd server printcap database information.
#   This list is searched after the printcap_path list is searched.	See
#   PRINTCAP LOOKUP for details.
#

mail_operator_on_error psz

# mail_operator_on_error (default: "")
#   Put this person on the CC-list of the mail, if it is not a success
#   mail. (So in addition to the person who made the printer request, also
#   this person gets error messages, but no success messages.)
#
# max_status_line (default: 79)
#   An integer value specifying the numbers of characters to be used for
#   displaying simple job status;  this includes the queue position, job
#   identifier,  job contents, size, and time.  A 0 (zero) value indicates
#   no restrictions.
#

max_status_size 50

# max_status_size (default: 10 (Kbytes))
#   An integer value specifying (in K bytes) the maximum size of the
#   status file to be generated during printing operations.	A 0 value
#   will create unlimited size status files.	 When the file size exceeds
#   this value, it is truncated to min_status_size K bytes.
#
# mc (default: 1)
#   See printcap(5) for details.
#

min_status_size 25

# min_status_size (default: 0 (Kbytes))
#   Minimum status size.  If 0, defaults to 20 percent of max_status_size.
#

minfree 100000

# minfree (default: 0)
#   The amount of free space (in Kbytes) needed in the spool directory in
#   order for a job to be accepted.	If 0, there is no limit; if the
#   parameter is the name of a file rather than a number, the file must
#   contain a numerical minimum free value (in Kbytes).  This value is
#   overriden by the printcap mi field value.
#
# ms_time_resolution
#   (default: FALSE) This flag causes the time information to be printed
#   to millisecond accuracy.	 This is overkill for most purposes.
#
# of_filter_options
#   (default: "") If this is not set, the value defaults to the same as
#   the filter_options value.  This string is appended to a OF filter
#   specification, and the string expanded with values from the printcap
#   information and job information.	 If the "bkf" (backwards compatible
#   filter) flags is set in the printcap entry, of bk_of_filter_options
#   value is appended instead (see of_filter_options, filter_options,
#   bk_filter_options, bk_of_filter_options)
#
# originate_port
#   (default: "721 731") A range of port numbers to orginate requests
#   from.  When sending service requests, the software will try to open
#   and bind to these ports to originate a request to a server.  If no
#   port is given, or all of the requested ports are unavailable or cannot
#   be bound to, then a normal use port is requested.  Note that on UNIX
#   systems, if a port in the range 0-1023 is requested the EUID of the
#   process must be root for the request to be granted.  Note that RFC1179
#   specifies that requests must originate from ports in the range 721-
#   731.
#
# pass_env
#   (default: "PGPPASS,PGPPATH") Client programs such as LPR, LPC, etc.,
#   will pass these environment variables to any filter programs they
#   start.
#

poll_time 600

# poll_time (default: 6000)
#   Interval in seconds at which LPD checks for queues with jobs and no
#   server active.  See force_poll as well.
#
# pl (default: 66)
#   See printcap(5) for details.
#
# pr (default: /bin/pr)
#   See printcap(5) for details.
#

printcap_path /usr/sms/share/LPRng/etc/printcap

# printcap_path
#   (default: "etc/printcap:/usr/etc/printcap:/var/spool/lpd/printcap.%h")
#   The location of the printcap database information.  If a file or
#   filter does not exist, it is skipped.  All valid entries in these
#   files will be used.  See PRINTCAP LOOKUP for details.
#

perms_path /usr/sms/share/LPRng/etc/lpd.perms

# perms_path
#   (default:
#   /etc/lpd.perms:/usr/etc/lpd.perms:/var/spool/lpd/lpd.perms.%h) The
#   location of the printer permissions database.  If a file or filter
#   does not exist, it is skipped.  The first file or filter that exists
#   and is readable will be used.  See PERMISSIONS LOOKUP for details.
#
# pw (default: 80)
#   See printcap(5) for details.
#
# remote_user (default: "")
#   The authentication information name of the remote server.  If no value
#   provided for this name, the default is the "user" value.	 This name
#   can have a %X field which is expanded in the same manner as the confi-
#   guration information.
#
# save_on_error
#   (default: no) Save a job in the spool queue if it has an error rather
#   than removing it.
#
# save_when_done
#   (default: no) Save a job in the spool queue after completion rather
#   than removing it.
#
# send_data_first
#   (default: no) Send data files of a job first, followed by the control
#   file.
#
# send_failure_action (default: "")
#   The lpd server uses this to determine the action to take when unable
#   to print or process a job.  The keyword abort will cause it to ter-
#   minate operations, leaving the job in the queue, remove will cause it
#   to remove the job, retry will cause it to retry the job, and hold will
#   cause it to hold the job with an error indication.  If the value is a
#   filter, then the filter will be invoked and the exit status of the
#   filter used to determine the actions.
#

send_job_rw_timeout 604800
## A week: we do not want things to time out, ever.
## Once stlw ran out of paper in the afternoon, and was not
## filled until the morning. We do not want to lose jobs.
## (In fact jobs sent to the printer in the morning were
## also lost: printer bug/confusion?)

# send_job_rw_timeout (default: 6000)
#   When printing or sending a job to a remote printer, use this as a
#   write to the device or remote host timeout value.  If a timeout
#   occurs, then a FAIL status is returned and the send_failure_action
#   value is used to determine what to do on failure.
#
# send_try (default: 3)
#   Numbers of times to try to send a job to the printer or remote host.
#   A 0 value means an infinite number of times.
#

sendmail ""

# sendmail (default: "/usr/lib/sendmail -oi -t")
#   If the argument is empty then all mail_related functionality is dis-
#   abled.  The arguments are the command to run when mail is to be sent.
#   The command used needs to be able to accept the message on stdin, with
#   no arguments.  The message will contain the To:, From:, Cc: and Sub-
#   ject: headers.
#
# server_auth_command (default: "")
#   The authentication program to be used by the server.
#

server_tmp_dir /usr/tmp

# server_tmp_dir (default: /tmp)
#   Temporary dir for the server.
#

server_user lprngd

# server_user (default: "daemon")
#   The authentication userid for a server.	Note that this entry will
#   have %P, %R, %M keys replaced by the printer, remote printer, and
#   remote host names.
#
# spool_dir_perms (default: 042700)
#   Permissions of the spool directories.
#
# spool_file_perms (default: 0600)
#   Permissions of the spool files.

#
# use_auth (default: "")
#   The authenication type to be used when sending a command.
#
# use_date (default: no)
#   No information about this parameter available.
#
# use_identifier (default: no)
#   Add a job identifier line to the control file, using the 'A' entry in
#   the control file.
#
# use_info_cache (default: yes)
#   If this is set to yes, lpd.perms and printcap information lookups will
#   be cached for later use.	 Only lookups in the main databases will be
#   cached, not lookups in the per_printer databases.  You can force the
#   lpd to flush its cache and reread the permissions file by sending it a
#   SIGHUP.
#

use_queuename yes

# use_queuename (default: no)
#   Put an entry into control files identifying the spool queue the job
#   was originally sent to.	The entry has the form 'Qspoolname', and its
#   value can be passed to filters.	This is useful for setting up a spool
#   queue which formats jobs in different ways, depending on the name of
#   the queue.
#
# use_shorthost (default: no)
#   By default, names of lpr job files used the originating host fully
#   qualified domain name.  This can exceed 14 characters, the limit of
#   file names on some UNIX systems.	 If this is set to yes, the non-
#   qualified name will be used, and if the host name is at most 8 charac-
#   ters the file name will be at most 14 characters long.
#

user lprngd

# user (default: daemon)
#   The user that lpd and its filters runs as, and the owner of the spool
#   directories and other lpd_writable files.  This can be the name of a
#   user or a number.  If the user value is 0, then the real UID of the
#   program when started will be used.  This allows a non_root user to
#   test the functionality of the LRPng software.
#
#
# SERVER=U AND ALLOW_LPC CONFIGURATION VARIABLE
#   (stolen from lpd.perms file)
#

allow_lpc=hold,release

#   The allow_lpc configuration variable can be used to specify a subset of the
#   standard lpc operations will be classified as U operations.  The candidates
#   for selection include hold, release, move, and topq.	For example, if the
#   allow_lpc variable had the value:
#   allow_lpc=hold,release
#
#   Then the following permissions entry would allows users to hold or release
#   their own jobs:
#   ACCEPT SERVICE=U SAMEUSER SAMEHOST REJECT SERVICE=U
#
#   When checking permissions, if permission is explicitly granted for
#   SERVICE=C operations, it must be done before the checks for U or S ser-
#   vices.
#
#
# PRINTCAP LOOKUP, DATABASE FILES AND FILTERS
#
#   The printcap_path and printer_perms_path variables specify a list of either
#   data base files or filters to use to get printcap or permission entries for
#   a printer.  To get information, the filter is started and a single line
#   with the printer name is sent to it.	Note that the printer name all is
#   used to request information either about all printers, or a specific
#   printer entry that has a list of all printers.  See printcap(5) for more
#   details.
#
#   To find the printcap information, client programs will first search the
#   database files specified in the printcap_path entry.	The lpd server will
#   also search the lpd_printcap_path entries as well.  After having searched
#   the various files, if a filter has been specified the filter will be
#   started and the required printer name will be sent to the filter.  The out-
#   put from the filter will be used as the printcap information.
#   user_auth_command (defaults: "") No description available.
#
#
# SECURITY-RELATED PARAMETERS
#
#   Environment variables are sanitized by lpd and the other executables, in
#   that the variables IFS, LD_PRELOAD and LD_PROFILE are all deleted from the
#   environment passed to filters and any other sub_processes.  For more relia-
#   bility, script filters should set their own PATH and LD_LIBRARY_PATH vari-
#   ables.
#
#   All filters will run as the user and group specified by the group and user
#   variables.
