Introduction

Ce document décrit comment installer le serveur d'impression CUPS sur un NetBSD 1.6.x et 2.x. Le service CUPS servira à gérer une imprimante HP LaserJet 6P, via un boitier externe (éthernet, parralelle) HP JetDirect EX.

Présentation de la maquette

  • un serveur de spool d'impression sous NetBSD 1.6.x ou 2.x
  • un serveur DHCP, bootpd, tftpd, syslogd
  • un boitier d'impression HP Jetdirect EX
  • une imprimante HP LaserJet 6P

Le boitier d'impression HP JetDirect EX :

  • obtient son adresse IP via DHCP. Il s'appelle : jd.leaves.org
  • écoute les demandes d'impression sur le port TCP 9100. Ce port correspond au mode d'impression raw.

Note

Toutes les commandes présentées ici, sont à executer, sauf mention contraire, en tant qu'administrateur de la machine.

Pré-requis

Ce document suppose que le serveur DHCP, bootp :

  • est installé est fonctionne convenablement,
  • attribut statiquement l'adresse IP jd.leaves.org au boitier HP JetDirect EX.

Installation de CUPS

Modifier le fichier /etc/mk.conf

Ajouter la ligne suivante dans le fichier /etc/mk.conf

# echo "USE_CUPS=YES" >> /etc/mk.conf

Ainsi, tous les packages installés dans le futur auront le support d'impression CUPS.

Modifier le fichier /etc/rc.conf

Par défaut, les systèmes NetBSD sont livrés avec le serveur d'impression lpd. Pour utiliser CUPS, il faut désactiver le serveur lpd et activer le serveur cupsd.

Ajouter les lignes suivantes dans le fichier /etc/rc.conf :

# Start printing daemon
lpd=NO      lpd_flags="-ld" #-s "secure" unix domain only
cupsd=YES
slpd=YES

Installation du package CUPS

Procédez comme suit :

# cd /usr/pkgsrc/print/ghostscript-esp
# make install clean clean-depends
#
# cd /usr/pkgsrc/print/cups
# make install clean clean-depends

Démarrer le service

Pour activer le service automatiquement au démarrage de la machine, procédez comme suit :

Modifier le fichier /etc/rc.local

Ajouter les lignes suivantes :

# Start CUPS (printing daemon)
if [ -x /usr/pkg/etc/rc.d/slpd ]; then
	 /usr/pkg/etc/rc.d/slpd start
fi
if [ -x /usr/pkg/etc/rc.d/cupsd ]; then
	/usr/pkg/etc/rc.d/cupsd start
fi

Modifier le fichier /etc/rc.shutdown.local

Pour stoper proprement le service CUPS lors de l'arrêt de la machine, ajouter les lignes suivantes :

# Stop CUPS (printing daemon)
if [ -x /usr/pkg/etc/rc.d/cupsd ]; then
	/usr/pkg/etc/rc.d/cupsd stop
fi
if [ -x /usr/pkg/etc/rc.d/slpd ]; then
	/usr/pkg/etc/rc.d/slpd stop
fi

Configuration du service

Via l'interface WEB

Par défaut, l'utilisateur root peut se logger via l'interface web. Ce n'est pas sécurisé, car le mot de passe transite en clair. Pour qu'un utilisateur puisse gérer les imprimantes via l'interface web, il faut qu'il appartienne au groupe sys (guid=3).

Créer un utilisateur dédié avec les paramètres suivants :

cups:*:116:3:CUPS web admin user:/nonexistent:/sbin/nologin

Pour accéder à l'interface Web d'administration, et créer une imprimante, procédez comme suit :

# lynx http://localhost:631/admin


Menu "Administration"
	 Section "Printers"
	 Cliquez sur "Add Printers"
 
Page "Add New Printer"
	Name 		: lp
	Location	: Office Number 1
	Description	: LaserJet 6p on JetDirect Ex
	Cliquez sur "Continue"

Page "Device for lp"
	Device 		: AppSocket/HP JetDirect
	Cliquez sur "Continue"

Page "Device URI for lp"
	Device URI	: socket://jd.leaves.org:9100
	Cliquez sur "Continue"

Page "Model/Driver for lp"
	Make		: HP
	Cliquez sur "Continue"

Page "Model/Driver for lp"
	Model		: HP LaserJet Series CUPS v1.1 (en)
	Cliquez sur "Continue"

L'interface génère le fichier /usr/pkg/etc/cups/printers.conf suivant :

<Printer lp>
Info LaserJet 6p on JetDirect Ex
Location Office Number 1
DeviceURI socket://jd.leaves.org:9100
State Idle

JobSheets none none
QuotaPeriod 0
PageLimit 0
KLimit 0
</Printer>

Via l'interface CLI

A faire….

Renommer les commandes lp*

Les commandes lp fournies par défaut avec un systeme NetBSD utilisent le service lpd. Elles ne sont pas compatibles avec le service CUPS. Il faut donc, soit les renommer, soit changer le PATH pourqu'il pointe vers les binaires lp* de CUPS.

Dans la configuration suivante, la première option est retenue.

# ls -l /usr/bin/lp*
-r-xr-xr-x  1 root  wheel    2520 Mar 28  2003 /usr/bin/lp
-r-sr-sr-x  1 root  daemon  21673 Dec  1  2004 /usr/bin/lpq
-r-sr-sr-x  1 root  daemon  28515 Dec  1  2004 /usr/bin/lpr
-r-sr-sr-x  1 root  daemon  25889 Dec  1  2004 /usr/bin/lprm
#
# cd /usr/bin
# mv lp lp.orig
# mv lpq lpq.orig
# mv lpr lpr.orig
# mv lprm lprm.orig
# ls -l /usr/bin/lp*
-r-xr-xr-x  1 root  wheel    2520 Mar 28  2003 /usr/bin/lp.orig
-r-sr-sr-x  1 root  daemon  21673 Dec  1  2004 /usr/bin/lpq.orig
-r-sr-sr-x  1 root  daemon  28515 Dec  1  2004 /usr/bin/lpr.orig
-r-sr-sr-x  1 root  daemon  25889 Dec  1  2004 /usr/bin/lprm.orig

Configuration d'un client

Client CUPS

Par défaut CUPS partage toutes les imprimantes qui lui sont rattachées.

Pour configurer un client, executer la commande suivante :

# lpadmin -p lp -E -v ipp://smoking/printers/lp

Pour imprimer :

# lpr -P lp /etc/hosts

Client LPD

A faire….

Client Windows XP ou 2000

Il existe deux possibilités pour imprimer depuis un poste Windows XP ou 2K :

  • par CIFS (samba)
  • par IPP en natif

Dans ce document, la deuxième option a été retenue. En effet, les Windows XP et 2000 intègrent en natif le support du protocole IPP. Cela évite, sur le serveur Unix de configurer un service supplémentaire.

En tant qu'utilisateur privilegié sur le poste Windows, cliquer sur :

Menu Démarrer -> Paramètres -> Imprimantes et Télécopieurs

Une fenêtre s'ouvre : "Imprimantes et Télécopieurs"
 Cliquer sur : 
	Ajouter une imprimante

Une fenêtre souvre : "Assistant Ajout d'imprimante"
 Cliquer sur :
	Suivant
 Sélectionner le bouton :
	"Une imprimante réseau ou une imprimante connectée à un autre ordinateur"
 Cliquer sur : 
	Suivant
 Sélectionner le bouton :
	"Se connecter à une imprimante sur Internet ou sur un réseau domestique ou d'entreprise"
 Saisir l'URL : 
	http://smoking.leaves.org:631/printers/lp
 [Note : ne pas oublier de préciser le port 631]
 Cliquer sur :
	Suivant

Votre imprimante est configurée !

# 
# NOTE: Unfortunately, most web browsers don't support TLS or HTTP Upgrades
# for encryption.  If you want to support web-based encryption you'll
# probably need to listen on port 443 (the "https" port...)
#
# NOTE 2: In order for the command-line and web interfaces to work, you

######## Browsing Options
########

#
# Browsing: whether or not to broadcast and/or listen for CUPS printer
# information on the network.  Enabled by default.
#

#Browsing On
#(#
Browsing Off

#
# BrowseProtocols: which protocols to use for browsing.  Can be
# any of the following separated by whitespace and/or commas:
#
#     all  - Use all supported protocols.
#     cups - Use the CUPS browse protocol.
#     slp  - Use the SLPv2 protocol.
#
# The default is "cups".
#
# NOTE: If you choose to use SLPv2, it is *strongly* recommended that
#       you have at least one SLP Directory Agent (DA) on your
#       network.  Otherwise, browse updates can take several seconds,
#       during which the scheduler will not respond to client
#       requests.
#

#BrowseProtocols cups

#
# BrowseAddress: specifies a broadcast address to be used.  By
# default browsing information is not sent!
#
# Note: HP-UX does not properly handle broadcast unless you have a
# Class A, B, C, or D netmask (i.e. no CIDR support).
#
# Note: Using the "global" broadcast address (255.255.255.255) will
# activate a Linux demand-dial link with the default configuration.
# If you have a LAN as well as the dial-up link, use the LAN's
# broadcast address.
#
# The @LOCAL address broadcasts to all non point-to-point interfaces.
# For example, if you have a LAN and a dial-up link, @LOCAL would
# send printer updates to the LAN but not to the dial-up link.
# Similarly, the @IF(name) address sends to the named network
# interface, e.g. @IF(eth0) under Linux.  Interfaces are refreshed
# automatically (no more than once every 60 seconds), so they can
# be used on dynamically-configured interfaces, e.g. PPP, 802.11, etc.

#
# BrowseShortNames: whether or not to use "short" names for remote printers
# when possible (e.g. "printer" instead of "printer@host".)  Enabled by
# default.
#

#BrowseShortNames Yes

#
# BrowseAllow: specifies an address mask to allow for incoming browser
# packets. The default is to allow packets from all addresses.
#
# BrowseDeny: specifies an address mask to deny for incoming browser
# packets. The default is to deny packets from no addresses.
#
# Both "BrowseAllow" and "BrowseDeny" accept the following notations for
# addresses:
#
#     All
#     None
#     *.domain.com
#     .domain.com
#     host.domain.com
#     nnn.*

#
# The hostname/domainname restrictions only work if you have turned hostname
# lookups on!
#

#BrowseAllow address
#BrowseDeny address
#(#
BrowseAllow None
BrowseDeny All

#
# BrowseInterval: the time between browsing updates in seconds.  Default
# is 30 seconds.
#
# Note that browsing information is sent whenever a printer's state changes
# as well, so this represents the maximum time between updates.
#
# Set this to 0 to disable outgoing broadcasts so your local printers are
# not advertised but you can still see printers on other hosts.
#

#BrowseInterval 30
#(#
BrowseInterval 0

#
# BrowseOrder: specifies the order of BrowseAllow/BrowseDeny comparisons.
#

#BrowseOrder allow,deny
#BrowseOrder deny,allow
#(#
BrowseOrder deny,allow

#
# BrowsePoll: poll the named server(s) for printers
#

#BrowsePoll address:port

#
# BrowsePort: the port used for UDP broadcasts.  By default this is
# the IPP port; if you change this you need to do it on all servers.
# Only one BrowsePort is recognized.
#

#BrowsePort 631

#
# BrowseRelay: relay browser packets from one address/network to another.
#

#BrowseRelay source-address destination-address
#BrowseRelay @IF(src) @IF(dst)

#
# BrowseTimeout: the timeout for network printers - if we don't
# get an update within this time the printer will be removed
# from the printer list.  This number definitely should not be
# less the BrowseInterval value for obvious reasons.  Defaults
# to 300 seconds.
#

#BrowseTimeout 300

#
# ImplicitClasses: whether or not to use implicit classes.
#
# Printer classes can be specified explicitly in the classes.conf
# file, implicitly based upon the printers available on the LAN, or
# both.
#
# When ImplicitClasses is On, printers on the LAN with the same name
# (e.g. Acme-LaserPrint-1000) will be put into a class with the same
# name. This allows you to setup multiple redundant queues on a LAN
# without a lot of administrative difficulties.  If a user sends a
# job to Acme-LaserPrint-1000, the job will go to the first available
# queue.
#
# Enabled by default.
#

#ImplicitClasses On

#
# ImplicitAnyClasses: whether or not to create "AnyPrinter" implicit
# classes.
#
# When ImplicitAnyClasses is On and a local queue of the same name
# exists, e.g. "printer", "printer@server1", "printer@server1", then
# an implicit class called "Anyprinter" is created instead.
#
# When ImplicitAnyClasses is Off, implicit classes are not created
# when there is a local queue of the same name.
#
# Disabled by default.
#

#ImplicitAnyCLasses Off

#
# HideImplicitMembers: whether or not to show the members of an
# implicit class.
#
# When HideImplicitMembers is On, any remote printers that are
# part of an implicit class are hidden from the user, who will
# then only see a single queue even though many queues will be
# supporting the implicit class.
#
# Enabled by default.
#

#HideImplicitMembers On

#
# SystemGroup: the group name for "System" (printer administration)
# access.  The default varies depending on the operating system, but
# will be "sys", "system", or "root" (checked for in that order.)
#

#SystemGroup sys
#(#
SystemGroup sys

#
# RootCertDuration: How frequently the root certificate is regenerated.
# Defaults to 300 seconds.

#    (Note: local certificate authentication can be substituted by
#           the client for Basic or Digest when connecting to the
#           localhost interface)
#
# AuthClass: the authorization class; currently only "Anonymous", "User",
# "System" (valid user belonging to group SystemGroup), and "Group"
# (valid user belonging to the specified group) are supported.
#
# AuthGroupName: the group name for "Group" authorization.
#
# Order: the order of Allow/Deny processing.
#
# Allow: allows access from the specified hostname, domain, IP address,
# network, or interface.
#
# Deny: denies access from the specified hostname, domain, IP address,
# network, or interface.
#
# Both "Allow" and "Deny" accept the following notations for addresses:
#
#     All
#     None
#     *.domain.com
#     .domain.com
#     host.domain.com
#     nnn.*
#     nnn.nnn.*
#     nnn.nnn.nnn.*
#     nnn.nnn.nnn.nnn
#     nnn.nnn.nnn.nnn/mm
#     nnn.nnn.nnn.nnn/mmm.mmm.mmm.mmm
#     @LOCAL
#     @IF(name)
#
# The host and domain address require that you enable hostname lookups
# with "HostNameLookups On" above.
#
# The @LOCAL address allows or denies from all non point-to-point
# interfaces.  For example, if you have a LAN and a dial-up link,
# @LOCAL could allow connections from the LAN but not from the dial-up
# link.  Similarly, the @IF(name) address allows or denies from the
# named network interface, e.g. @IF(eth0) under Linux.  Interfaces are
# refreshed automatically (no more than once every 60 seconds), so
# they can be used on dynamically-configured interfaces, e.g. PPP,
# 802.11, etc.
#
# Encryption: whether or not to use encryption; this depends on having
# the OpenSSL library linked into the CUPS library and scheduler.
#
# Possible values:
#
#     Always       - Always use encryption (SSL)
#     Never        - Never use encryption
#     Required     - Use TLS encryption upgrade
#     IfRequested  - Use encryption if the server requests it
#
# The default value is "IfRequested".
