Hello List -
I am trying to get CUPS servers set up on my SOHO network and so far no
joy in getting it to work properly. So hopefully some nice guru will
help me get through these woods. Sorry this is so long, but I figure it
is best to give as much info as I can.
I think I probably am facing a number of issues, so will start with a
basic description of my network and then try to tackle issues one at a
time. My network consists of a number of Linux (SuSE), Windows (XP,
2000, and Vista) systems. One of the Linux computers is acting as a
central Print (CUPS) server. A Windows2000 computer is the one to which
my printer is actually attached. In order for Linux to use this printer
(a Canon Pixma MP780) I have installed Turboprint on the central
computer. My shaky understanding of Turboprint is that is supplies an
underlying driver to format print jobs correctly before the CUP's server
sends the jobs on to the Win2K computer.
So far, if I submit a print job on the central Linux computer, the CUPS
server on that computer will process the job correctly and send it on to
the Win2K system, and the printout will take place. All Windows
computers connect directly to the Win2K system for printing and they all
work fine also.
However the trouble I am having is when I try to submit a print job from
one of my Linux systems (other than the central one) One each of these
Linux systems, I have tried various methods of connecting to the central
Linux computer and so far no joy. My current attempt is to configure the
CUPs server on each of the Linux computers to connect to Samba on the
central computer, and have Samba forward the print request on to CUPS on
the same central computer. (The folks on the SuSE users group said that
they have experienced a lot of difficulties trying to set up a CUPS
client on a Linux system and connect directly to the CUPS server and
advised me to go through Samba instead.)
I suspect my main difficulties stem from authentication issues, but I am
not certain. So my first question is - IS there any way to trace the
authentication process to determine WHY it may be failing? Or
alternatively, to determine that it is succeeding?
Looking at the CUPS error.log file I am also seeing an error message
that I probably should tackle first. Upon starting the CUPS server on
one of my other Linux systems, I see the following error about a failure
to bind a socket for address because the address is already in use.
Say what? I got no idea what that means really, or why it is happening.
This is in the log right after I boot up the system, and repeats if I
restart the CUPS server. How do I get to the bottom of this, or is it
something I can ignore? There are also a couple other error messages
about a server.crt and server.key files that don't exist. Why and what
should I do about them?

Once I get the system up and running, and try to send a print job, the
error.log file shows me that the print job was not authorized. I have
tried to study and understand the documentation on cupsd.conf and to the
best of my understanding I set the Authtype parameter to None in all the
sections that I think are appropriate. So if Authtype is None, why do I
get an error message such as what is shown here?
I [29/Oct/2009:19:23:04 -0700] Resuming new connection processing...

I [29/Oct/2009:19:24:24 -0700] [Job 136] Completed successfully.
This, to my untrained eyes, seems to be giving me a conflicting message
when a print job was submitted! On the one hand there is an error
message saying the print job was unathorized. On the other hand there is
a message saying the job completed successfully! So I am confused! And I
will be the first to admit I do not understand all the documentation I
have tried to read. The stuff on authentication just gives me a
splitting headache trying to understand! Sigh...
I know someone will probably ask for it so here is my cupsd.conf file
from one of my Linux systems. I figure I should start here and then
worry about what is happening on the central server later....
# CUPS configuration file, generated by CUPS configuration tool.
# This tool is part of KDEPrint, the printing framework for KDE
# since version 2.2.2 and is used by the CUPS supporting module
# in KDEPrint. The predecessors to KDEPrint in former KDE releases
# were KUPS and QtCUPS; they are deprecated and no longer maintained.

########################################################################
# #
# This is the CUPS configuration file. If you are familiar with #
# Apache or any of the other popular web servers, we've followed the #
# same format. Any configuration variable used here has the same #
# semantics as the corresponding variable in Apache. If we need #
# different functionality then a different name is used to avoid #
# confusion... #
# #
########################################################################
#
# Server
# Server name (ServerName)
#
# The hostname of your server, as advertised to the world.

# nnn.nnn.nnn.nnn/mmm.mmm.mmm.mmm
#
# The host and domain address require that you enable hostname lookups
# with "HostNameLookups On" above.
#
# Encryption: whether or not to use encryption; this depends on having
# the OpenSSL library linked into the CUPS library and scheduler.

#
# You can have multiple Port/Listen lines to listen to more than one
# port or address, or to restrict access.
#
# Note: Unfortunately, most web browsers don't support TLS or HTTP Upgrades

# Whether or not to listen to printer
# information from other CUPS servers.
#
#
# Enabled by default.
#
#
# Note: to enable the sending of browsing
# information from this CUPS server to the LAN,
# specify a valid BrowseAddress.
#
#
# ex: On
#
#Browsing On
Browsing On
# Browse protocols (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 response to client
# requests.
#
#BrowseProtocols cups
BrowseProtocols CUPS
# Browse 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.
#
# ex: 631
#
#BrowsePort 631
BrowsePort 631
# Browse interval (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.
#
# ex: 30
#
#BrowseInterval 30
BrowseInterval 30
# Browse timeout (BrowseTimeout)
#
# The timeout (in seconds) 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.
#
# ex: 300
#
#BrowseTimeout 300
BrowseTimeout 300
# Browse addresses (BrowseAddress)
#
# Specifies a broadcast address to be used. By
# default browsing information is broadcast to all active interfaces.
#
# Note: HP-UX 10.20 and earlier do not properly handle broadcast unless
# you have a Class A, B, C, or D netmask (i.e. no CIDR support).
#
# ex: x.y.z.255, x.y.255.255
#
#BrowseAddress x.y.z.255
#BrowseAddress x.y.255.255
#BrowseAddress x.255.255.255
BrowseAllow all
BrowseAddress @LOCAL
# Browse order (BrowseOrder)
#
# Specifies the order of BrowseAllow/BrowseDeny comparisons.
#
# ex: allow,deny
#
#BrowseOrder allow,deny
#BrowseOrder deny,allow
BrowseOrder allow,deny
# Implicit classes (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 Off
ImplicitClasses On
# Use "any" classes (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 at server1", "printer at 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
ImplicitAnyClasses Off
# Hide implicit members (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
