LPD.CONF(5)							   LPD.CONF(5)

       lpd.conf - configuration file for the LPRng line printer spooler system

       The  file lpd.conf is used to provide configuration information for the
       LPRng Printer spooler system and	 defaults  for	printcap  information.
       Leading	spaces	on  lines are ignored, and blank lines and lines whose
       first nonblank 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:
       Note that these values are the same format as printcap(5) values.  Val‐
       ues in the configuration can contain host or machine dependent informa‐
       tion;  to  assist with this, the following escape sequences in the con‐
       figuration 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 configuration file and is set to a  default  value  at  com‐

       %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 print‐
       cap  :sd:  (spool  directory)  and  :forward_server:  (forward  server)
       entries use these.

       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 (whitespace) as well.

       Keyword names can use either underscores (_) or hyphens	(-)  in	 their
       names, but the underscore is preferred.

       include pathname [pathname*] (no default)
	      This  can	 be used to include files into the lpd.conf file.  The
	      include file parameter a 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
	      configuration 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.

	      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

       auth (default: NULL)

       auth_forward_filter (default: NULL)
	      Program to be used for server to server communication.

       auth_forward_id (default: NULL)
	      Authentication id of remote server for server to server communi‐

       auth_receive_filter (default: NULL)
	      Program to be used by server receive server or client communica‐

       auth_server_id (default: NULL)
	      Authentication id of originating client or server.

       as (default: "jobstart $H $n $P $k $b $t")
	      See as.

       bk (default: no)
	      See printcap(5) for details.

	      (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 informa‐
	      tion  and	 job  information.    (see   of_filter_options,	  fil‐
	      ter_options, bk_filter_options, bk_of_filter_options)

	      (default: "$w $l $x $y") If the "bkf" (backwards compatible fil‐
	      ter) flags is set in the printcap entry and the original	filter
	      specification  does  not have a `$` 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,

       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  sup‐
	      plied.  Note that files containing HPGL or other printer control
	      languages would often be classed as ``non_printable''.

       connect_grace (default: 0 seconds)
	      The time to pause before opening a new connection to a  printer.
	      This allows the printer time to recover from the previous job.

       connect_interval (default: 10 (seconds))
	      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_banner_printer (default: "")
	      The  default banner printer program to be used for printing ban‐
	      ners.  This should be specified in the LPD configuration file.

       default_format (default: "f")
	      Default format for printing jobs.

	      (default: 2001) specifies	 a  default  port  number  for	logger
	      information.  See logger_destination for details.

	      (default:	 UDP) specifies a default protocol for logger informa‐
	      tion.  See logger_destination for details.

       default_permission (default: ACCEPT)
	      Default permission for operations.

       default_printer (default: "")
	      The default printer to use if there is  no  PRINTER  environment
	      variable,	 the  user has not specified a printer, or there is no
	      printcap information.

       default_priority (default: "A")
	      Default priority (class) for printing jobs.  This is  also  used
	      as the job class.

	      The default remote host to use.

       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 into a fully_qualified domain name,  ie.	class.iona.ie.
	      It will only be used if the software cannot determine the domain
	      name using other means, such as gethostbyname(3n).

       ff (default: \f)
	      Formfeed string.

	      (default: /lib:/usr/lib:/usr/5lib:/usr/ucblib) The value for the
	      environment  variable LD_LIBRARY_PATH, both used when executing,
	      and passed on to filters.	 This variable is used to find	shared
	      libraries on SunOS, Solaris and Linux.

	      (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 $-a") If the "bkf" (backwards compatible
	      filter)  flags is not set in the printcap entry and the original
	      filter specification does not have a  `$`	 in  it,  this	option
	      string  is  appended  to	a filter specification, and the string
	      expanded with values  from  the  printcap	 information  and  job
	      information.   (see  of_filter_options,  filter_options, bk_fil‐
	      ter_options, bk_of_filter_options)

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

       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 looking for jobs  and  no  server.	The  poll_time
	      variable sets the interval between polls.

       full_time (default: no)
	      Use full time and date format in logging and error messages.

       fx (default: "")
	      See  printcap(5)	for  details.	This specifies the job formats
	      allowed for this queue.

       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
	      kerberos authentication.	The keytab file should be owned by the
	      LPD server, and be readable/writable only by it (i.e. - 600 per‐

       kerberos_life (default NULL)
	      The  lifetime  of	 a  Kerberos ticket.  NULL selects the default
	      lifetime.	 Time should be specified using the standard  Kerberos
	      time representations.

       kerberos_forward_principal (default NULL)
	      remote principal used by server when forwarding

       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_server_principal (default "lpr")
	      Server  principal	 used  when  client  sending to server or when
	      server is originating connection to another server for  forward‐

       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 ker‐
	      beros domain is ALPHA.COM,  then	the  kerberos  principal  name
	      would be:

       la (default: yes)
	      See printcap(5) for details.

       lf (default: log)
	      Name of the log file.

       lo (default: lock)
	      Name of the lock file.

	      (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  connec‐
	      tions from different interfaces.

       lockfile (default: /var/spool/lpd/lpd)
	      The  file used to indicate the presence of an lpd server running
	      on the host.  The lpd_port value is  appended  to	 the  lockfile
	      value  to provide a unique lockfile even when different versions
	      of LPRng are running on the same system.

	      (default: "") This specifies a destination for  logger  informa‐
	      tion generated by the lpd server.	 The formation of the destina‐
	      tion specification  is  host[%port][,(TCP|UDP)].	 For  example,
	      localhost%2001,UDP  would	 send logger information to the local‐
	      host 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.

	      (default: no) RFC1179 requires  3	 digit	job  numbers;  setting
	      longnumber to yes allows 6 digit numbers.	 If the backwards_com‐
	      patible flag is set, only 3 digit numbers will be used.

       lpd_port (default: printer)  [ipaddr%]port
	      The port that lpd binds to, and that lpr and  the	 other	client
	      programs send their requests to.	The specification has the for‐
	      mat ipaddr%port.	If the ipaddress is specified then a  bind  to
	      only  this address and port is done.  If the port value is not a
	      number a service lookup is performed and the corresponding  ser‐
	      vice  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 (default: "")
	      The location of lpd server only printcap	database  information.
	      If  this	is nonblank the printcap_pathP will not be used by the
	      lpd server.

       mail_operator_on_error (default: "")
	      Put this person on the CC-list of the mail, if it is not a  suc‐
	      cess  mail.  (So	in addition to the person who made the printer
	      request, also this person gets error messages,  but  no  success

       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 posi‐
	      tion, job identifier,  job contents, size, and time.  A 0 (zero)
	      value indicates no restrictions.

       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

       mc (default: 1)
	      See printcap(5) for details.

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

       minfree (default: 0)
	      The  amount of free space (in Kbytes) needed in the spool direc‐
	      tory 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 num‐
	      ber, the file must contain a numerical minimum  free  value  (in
	      Kbytes).	 This  value  is  overriden  by	 the printcap mi field

	      (default: FALSE) This flag causes the  time  information	to  be
	      printed to millisecond accuracy.	This is overkill for most pur‐

	      (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_fil‐

	      (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.

	      (default:	 "PGPPASS,PGPPATH")  Client programs such as LPR, LPC,
	      etc., will pass these environment variables to any  filter  pro‐
	      grams they start.

       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.

	      (default: "/usr/local/etc/printcap") The location of the	print‐
	      cap  database  file.   If a file or filter does not exist, it is
	      considered a fatal error.	 All valid entries in these files will
	      be used.	See PRINTCAP LOOKUP for details.

	      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.

	      (default: no) Save a job in the spool queue if it has  an	 error
	      rather than removing it.

	      (default:	 no)  Save  a  job in the spool queue after completion
	      rather than removing it.

	      (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 terminate 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

       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 time‐
	      out occurs, then a FAIL status is returned  and  the  send_fail‐
	      ure_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 (default: "/usr/lib/sendmail -oi -t")
	      If the argument is empty then all mail_related functionality  is
	      disabled.	  The arguments are the command to run when mail is to
	      be sent.	The command used needs to be able to accept  the  mes‐
	      sage  on stdin, with no arguments.  The message will contain the
	      To:, From:, Cc: and Subject: headers.

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

       spool_dir_perms (default: 042700)
	      Permissions of the spool directories.

       spool_file_perms (default: 0600)
	      Permissions of the spool files.

       syslog_device (default: /dev/console)
	      Log to this device if all else fails.

       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 data‐
	      bases.  You can force the lpd to flush its cache and reread  the
	      permissions file by sending it a SIGHUP.

       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  'Qspool‐
	      name',  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 characters the file name will be at most 14 charac‐
	      ters long.

       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.

       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 print‐
       cap(5) for more details.

       To find the printcap information, LPRng programs will read the database
       files  specified	 in the printcap_path entry.  The lpd server will read
       any additional files specified in the lpd_printcap_path entry.  If  any
       of  the	files  is  missing  or non-readable a fatal error will result.
       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 output from the filter will be used as the printcap

       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 reliability, script filters should  set	 their	own  PATH  and
       LD_LIBRARY_PATH variables.

       All  filters  will run as the user and group specified by the group and
       user variables.

       #   The values in this file are the default values.
       #   If you modify the file,  set the value to something other than the default
       #   For example, '# default force_localhost' means
       #     the 'force_localhost' option value is on or 1.
       #   Uncomment this and change it to read 'force_localhost@'

       The files used by LPRng are set by values in the printer	 configuration
       file.  The following are a commonly used set of default values.
       /usr/local/etc/lpd.conf			    LPRng configuration file
       ${HOME}/.printcap			    user printer description file
       /usr/local/etc/printcap			    printer description file
       /usr/local/etc/lpd.perms			    permissions
       /var/run/lpd				    lock file for queue control
       /var/spool/lpd				    spool directories
       /var/spool/lpd/QUEUE/control		    queue control
       /var/spool/lpd/QUEUE/log			    trace or debug log file
       /var/spool/lpd/QUEUE/acct		    accounting file
       /var/spool/lpd/QUEUE/status		    status file

       lpc(8),	lpd(8),	 checkpc(8),  lpr(1),  lpq(1),	lprm(1),  printcap(5),
       lpd.perms(5), pr(1), lprng_certs(1), lprng_index_certs(1).

       Most of the diagnostics are self explanatory.
       If you are puzzled over the exact cause of failure,
       set the debugging level on (-D5) and run again.
       The debugging information will
       help you to pinpoint the exact cause of failure.
