cupsys 1.2.1-0ubuntu1 doesn't support 11.22.33.* network masks

You have configuration from Breezy. On upgrade to Dapper you were asked if you want to keep old config or get a new one. Since you choosed old one, new cups package didn't overwrite it. And since new minor CUPS release didn't have any changes in config, it didn't ask you same question again.

CUPS 1.2 doesn't support RunAsUser, but you have a valid bug here:

Address masks with * are broken in CUPS.

On losts of installations this causes non funcional CUPS.

http://www.easysw.com/~mike/cups/newsgroups.php?s1841+gcups.commit+v1844+T0

This is trunk entry that should fix that.

This debdiff fixes this issue.

As a bonus, it fixes some errors in other patch and debian/rules (and that makes cups rebuildable from same deb source :).

OK - quite likely that I chose the old config when I did the dist-upgrade,
because I had worked hard to get network printing to actually *work*! But
that was in May, and my "old" configuration has worked in Dapper, until
this "minor" upgrade.

The 1.2.0 worked fine with my config, as reported - it was the 1.2.1 that
broke.
(General comment on cups configuration: needs a simple GUI for setting
up network printing, or some buttons to say somehing like "allow
machines on your local network to use this printer".)

OK - glad that one is of some use, at least :-)

I have a similar problem since the last upgrade:
/var/log/cups/error_log:

Trying to start cupsys I get:
cupsd: Child exited on signal 15!

Hope this bug will be fixed soon.

On Dapper, this is trivial; if you want to browse for IPP shared
printers on network, only thing needed is:

sudo /usr/share/cups/enable_browsing 1

(this will enable browsing of printers on your local network)

If you want to share your local printers, only thing needed is:

sudo /usr/share/cups/enable_sharing 1

(this will allow printing on all of your printers from your local
network; for finer settings, you should manually edit cupsd.conf; but
read CUPS documentation first)

And GUI... Well, we are working on it :)

@TTL

At first glance, this doesn't look like problem related to this bug,
but as configuration issue. Please attach your /etc/cups/cupsd.conf
and /etc/cups/cups.d/browse.conf

Thanks.

@Karamatić:
Sorry, you are right. It was really a completely other bug. Running "sudo ifconfig lo 127.0.0.1" before, solved my problem with the cupsys configuration.

If it is as trivial as that, surely these commands could be coupled to a
few well-named buttons almost as trivially as the commands
themselves?

The solution you give is indeed trivial for those accustomed to using the
CLI for configuration - thanks for the hints - but that would look pretty
scary to Aunt Tilly ;-) I'm sure you've read ESR's rant about CUPS, so I
won't labour the point !

There is already GUI for detecting LAN printers (gnome-cups-manager),
and there is even patch for "sharing local printers" that might get in
for Edgy. But, new GUI is needed since gnome-cups-manager doesn't
support all options that new CUPS 1.2 offers, and probably for edgy+1
there will be new GUI.

Other than that, feel free to send patches or develop new GUI :)

Heh heh - I was expecting that response :)
I'm not a coder, unfortunately ;)

I would probably make a bash script, with an Xdialog GUI - but that would
be too ugly to live, of course!

(My only GUI project so far is a "Pizza Timer" ( priorities .. ) It's
really just guilding the lily from
 "sleep 14m && echo "Your pizza is ready" )

http://www.boinc.ch/~thoreauputic/Timer_Script.html

Anyway, I am drifting off-topic : thanks for your prompt responses to
the original bug report !

Ante, thank you for digging this out!

I confirmed that the patch works, and I also confirmed that RunAsUser doesn't stop cupsd from starting, so I won't fiddle with the configuration file in dapper-updates.

Matt, good to upload?

OK for dapper-updates

 cupsys (1.2.1-0ubuntu2) dapper-updates; urgency=low
 .
   * Add debian/patches/00_r5660.dpatch
     - Fix for 11.22.33.* network masks (STR #1769), Closes: LP#52390
   * Fixed debian/patches/05_avoidunknowngroup
     - Don't create .rej files
   * Fixed debian/rules
     - Delete backend/*.o on clean

 cupsys (1.2.2-0ubuntu1) edgy; urgency=low
 .
   * Merge to Debian unstable:
     - This gets rid of /etc/cups/conf.d/ again and re-merges the separate
       browsing and ports settings to /etc/cups/cupsd.conf again. Separating
       was nice for preserving an unchanged conffile for the most important
       settings, but it broke KDE and the web interface and generated way too
       many bugs. Closes: LP#37892, LP#50804, LP#53582
    * Update to new upstream version 1.2.2 (UVF exception granted by by Matt
      Zimmerman):
      - Fixes printing to 1.1.x servers. Closes: LP#42513, LP#42802
      - Fixes parsing of some PostScript files which previously generated empty
        pages. Closes: LP#51432
      - Fixes parsing of network masks. Closes: LP#52390
      - Lots of more fixes, see upstream changelog.
   * debian/cupsys.preinst: Drop some obsolete migration bits for
     Breezy->Dapper upgrade.
   * debian/control: Add libdbus-1-dev build dependency to enable dbus support.
   * debian/cupsys.examples: Do not ship .svn files (upstream Makefiles install
     them).
   * cupsys.postinst: Fix permissions of cupsd.conf to be writable by user
     cupsys world-readable.
   * debian/local/enable_{sharing,browsing}, {sharing,browsing}_status: Adapt
     to new single configuration file format.
   * debian/rules: Clean cups/raster.h symlink to unbreak source package build.
   * Add debian/patches/ubuntu-disable-browsing.dpatch: Disable browsing by
     default to avoid open port and stay compatible to previous releases.
