[résolu]Serveur CUPS un peu radin

Bonjour,

Je mouline depuis hier pour faire fonctionner mon serveur d'impression sous CUPS.

Il est installé sur un PC1 (IP fixe:192.168.0.X) à base d'Ubuntu 5.04.
En local, tout fonctionne à merveille.

Mais pour faire fonctionner mon imprimante sur mon autre PC2 (IP fixe:192.168.0.Y) à base de Debian testing. C'est un autre chose.

Mon gros problème est que je n'arrive pas à me connecter sur le serveur CUPS 192.168.0.X:631, depuis PC2.

J'ai pu remarquer avec nmap, que le port 631 est ouvert en 127.0.0.1, mais pas en 192.168.0.X. J'ai installé firestarter pour ouvrir le port: ça marche pas.
Je précise que cela ne peut pas venir de mon routeur non plus, dont le firewall/port-forwarding, est, on va dire, câblé sur la partie modem, tout le reste derrière est en DMZ par défaut.
J'ai aussi essayé ceci: ça marche pas.

Bref, je fait quoi?

######## Filter Options
########

#
# User/Group: the user and group the server runs under.  Normally this
# must be cupsys and lpadmin, however you can configure things for another
# user or group as needed.
#
# Note: the server must be run initially as root to support the
# default IPP port of 631.  It changes users whenever an external
# program is run, or if the RunAsUser directive is specified...
#

#User cupsys
#Group lpadmin

#
# RunAsUser: The RunAsUser directive controls whether the scheduler runs as the
# unpriviledged user account (usually cupsys). The default is No which
# leaves the scheduler running as the root user. However, the Debian package
# was prepared to work as user cupsys, which greatly reduces the impact of
# security holes.
#
# Note: Running as a non-priviledged user may prevent LPD and locally connected
# printers from working due to permission problems. The lpd backend will
# automatically use a non-priviledged mode that is not 100% compliant with RFC
# 1179. The parallel, serial, and usb backends will need write access to the
# corresponding device files.
#

RunAsUser Yes

#
# RIPCache: the amount of memory that each RIP should use to cache
# bitmaps.  The value can be any real number followed by "k" for
# kilobytes, "m" for megabytes, "g" for gigabytes, or "t" for tiles
# (1 tile = 256x256 pixels.)  Defaults to "8m" (8 megabytes).
#

#RIPCache 8m

#
# TempDir: the directory to put temporary files in.  This directory must be
# writable by the user defined above!  Defaults to "/var/spool/cups/tmp" or
# the value of the TMPDIR environment variable.
#

#TempDir /var/spool/cups/tmp

#
# FilterLimit: sets the maximum cost of all job filters that can be run
# at the same time.  A limit of 0 means no limit.  A typical job may need
# a filter limit of at least 200; limits less than the minimum required
# by a job force a single job to be printed at any time.
#
# The default limit is 0 (unlimited).
#

#FilterLimit 0

########
######## Network Options
########

#
# Ports/addresses that we listen to.  The default port 631 is reserved
# for the Internet Printing Protocol (IPP) and is what we use here.
#
# You can have multiple Port/Listen lines to listen to more than one
# port or address, or to restrict access:
#
#    Port 80
#    Port 631
#    Listen hostname
#    Listen hostname:80
#    Listen hostname:631
#    Listen 1.2.3.4
#    Listen 1.2.3.4:631
# 
# 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
# must have at least one Port or Listen line that allows access from the
# local loopback address (localhost).
#

##Port 80
#Port 443
#Port 631

Listen 127.0.0.1:631
# Listen 192.168.0.*:631

#
# HostNameLookups: whether or not to do lookups on IP addresses to get a
# fully-qualified hostname.  This defaults to Off for performance reasons...
#

#HostNameLookups On

#
# KeepAlive: whether or not to support the Keep-Alive connection
# option.  Default is on.
#

#KeepAlive On

#
# KeepAliveTimeout: the timeout before Keep-Alive connections are
# automatically closed.  Default is 60 seconds.
#

#KeepAliveTimeout 60

#
# MaxClients: controls the maximum number of simultaneous clients that
# will be handled.  Defaults to 100.
#

#MaxClients 100

#
# MaxClientsPerHost: controls the maximum number of simultaneous clients that
# will be handled from a specific host.  Defaults to 10 or 1/10th of the
# MaxClients setting, whichever is larger.  A value of 0 specifies the
# automatic (10 or 1/10th) setting.
#

#MaxClientsPerHost 0

#
# MaxRequestSize: controls the maximum size of HTTP requests and print files.
# Set to 0 to disable this feature (defaults to 0.)
#

#MaxRequestSize 0

#
# Timeout: the timeout before requests time out.  Default is 300 seconds.
#

#Timeout 300

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

#
# Browsing: whether or not to broadcast and/or listen for CUPS printer
# information on the network. For Ubuntu, this setting has been externalized to
# a separate configuration file cupsd-browsing.conf. This allows to change the
# browsing setting with /usr/share/cups/enable_browsing (or manually) without
# modifying this main configuration file, which avoids dpkg questions on
# conffile upgrades.

Include cupsd-browsing.conf

#
# 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

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

BrowseAllow address
#BrowseDeny address

#
# 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

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

#BrowseOrder allow,deny
#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


########
######## Security Options
########

#
# 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.)
#
# Debian: The default CUPS group is "lpadmin".
#

#SystemGroup lpadmin

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

#RootCertDuration 300

#
# Access permissions for each directory served by the scheduler.
# Locations are relative to DocumentRoot...
#
# AuthType: the authorization to use:
#
#    None   - Perform no authentication
#    Basic  - Perform authentication using the HTTP Basic method.
#    Digest - Perform authentication using the HTTP Digest method.
#
#    (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,

#     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".

Re : [résolu]Serveur CUPS un peu radin

Re,

je verrais bien un truc du genre :

#Listen 127.0.0.1:631
Listen 192.168.0.*:631

à la place de :

Listen 127.0.0.1:631
# Listen 192.168.0.*:631

Ok, le piège était de commenter 127.0.0.1:631.

C'est bien un truc auquel je n'avais pas du tout pensé.

En tout cas merci à vous, tout fonctionne à merveille.

Re : [résolu]Serveur CUPS un peu radin

Bonjour,

Juste un truc si ca vous arrive. En utilisant l'outil de configuration d'imprimante de Gnome, avec la version 5.04 d'Ubuntu, un message indiquait que mon mon serveur CUPS ne pouvait être contacté. La raison était que mon interface lo (loopback) n'était pas active. En faisant ifconfig lo 127.0.0.1, le problème fut réglé et j'ai pu installer mon imprimante sans problèmes. J'ai commencé avec Red Hat 5 à mes débuts et il y a pas mal de progrès côté impression. Lachez pas les développeurs !:cool:
