Titel: CUPS & Authentication

Any one else experiencing problems with CUPS?

Normally all users can have access to the printer if CUPS is configured
via KDE's kprint with "all users allowed". But since the last two CUPS
upgrades I find that users have have to be explicitly named in order to
gain the use of the printer. (CUPS error log showed authenication
errors.)

As some have noticed there have also been problems with kscreensaver
not working. While I'm no expert I'm beginning to suspect there is an
issue between parts of KDE and PAM authentication.

Anyone like to comment?

edit: I should have added that I suspect kcontrol as my main suspect.

From the lack of replies I must conclude I'm the only one experiencing
this problem. Oh well I guess I'll have to up the learning curve and
debug it myself!

with easter-2006rc4 since a dist-upgrade in the last few days,
I've noticed that I can no longer get printed output, unless
I reboot in that other OS. It is very embarassing and usually
happens when someone is waiting impatiently for something.

Sometimes repairable in the Kde PrintManager even though
I was using IceWM. Also had to remove the tmp files from the
/var/spool/cups/ as root. Reboot and sometimes it would wake
up again. Usually when returning from Windows, after printing,
where it always worked. Traurig

(

I'm sure I'm doing something incorrectly so I'll keep looking and
reading notes left by others who experience similar oddities.

Following might help:

apt-get remove --purge cupsys
apt-get install cupsys cupsconfig-kanotix cupsys-driver-gutenprint hplip

Afterwards you might also change /etc/cups/cups.d/ports.conf this way:

Code:

Listen localhost:631

# Listen /var/run/cups/cups.sock

EDIT:
Next step is to restart cups:
# /etc/init.d/cupsys restart

I did it in init 3, went back to KDE with init 4 and reinstalled the printer (an HP Deskjet 5440 through USB).

EDIT2:
The newest cups does not have /etc/cups/cups.d/ports.conf anymore. The line which to comment is now in /etc/cups/cupsd.conf.

Still problems here.

Haven't been able to print from Kanotix for the last several days (yes, yes, dist-upgrades almost every day).

Did the latest upgrade, no go. Followed hubi's instructions, with no improvements.
The documents seem to be sent to the printer correctly (green progress light blinks on the printer), but they never end up printing, and the printer's orange error light will blink, and other documents are blocked from being printed.

Any more suggestions? It's not a pressing issue (for me), as I can transfer things to a (gasp!) windows machine and print from there, but it'd be nice to get ironed out soonish.

Thanks!

anticapitalista,

as Richard is pointing out as well, you have to reinstall the printers. cups seems to be under reconstruction, but I do not have detailed information about it.

There might be a working solution for the kde here:

My entries are as stated, but I do not know if they were the same before my changes this morning.

I'm using the easter Preview Kanotix distro and dist-upgrade every day.

The CUPS upgrade of a few days ago required explicity naming users
able to access the printer. The printer drive also needed reinstalling.
Didn't restart CUPS although I think changing the driver via kcontrol->
kprint automatically restarts CUPS.

Yesterdays CUPS upgrade again required reinstalling the appropriate
printer driver via kcontrol->kprint.

In fact EVERY reboot requires reinstallation of the driver via kcontrol.

I suspect that most people print (as I do) via a KDE app and it's possible
that the CUPS problem is actually a KDE issue. eg CUPS config via KDE
is lost after a shutdown.

Since KDE went to 3.5.3 there have been some posts to the forum
concerning various config problems.
ie.
(a) kscreensaver confures and test OK but doesn't kick in whatever time
period is selected. (a problem which keeps cropping up after some KDE
upgrades.)
(b) Ksynaptics (don't use it myself so I can't comment)
(c) CUPS

I intend to have a look into this myself when time permits (annual holiday
looming) but in the meantime is anyone else experiencing difficulties when
configuring other peripherals via kcontrol?

same problems over here (Epson CX3200). I think CUPS itself is messed up. This is what I get when trying to restart CUPS:

Code:

I too am not able to print anymore, I always have to mail my job applications to a friend to get them printed now... I am using the Easter RC 4 and a Canon IP 6000 D which only can print via turboprint (so I even cannot use the live cd to print). I tried reinstalling turboprint and the printer but I still am not able to print. Cups version is current. Any further suggestions?

greybeard - 11.06.2006, 04:48 Uhr

Same problem here. The cups upgrade has broken printing on both of my printers (one parallel port and one USB). It seems to be some user, group, owner, or permission problem. But I have not been able to figure it out.

I've tried several combinations in the cupsd.conf file and would reinstall the printer in cups with each variation. I would sometimes get different error messages when trying to print a test page as root but they just end up in the printer queue.

Lucky for me, I imaged my drive. So I rolled it back to the stable point and can print once again.

I have read a couple of similar posts in the Redhat and Suse forums, so I don't think we are alone.

gardyloo - 11.06.2006, 20:07 Uhr
Titel: Works now.. and I don't know why

Yes, the Ubuntu/Mepis/whatever forums are full of similar complaints about CUPS.

Today I went in through the web interface (http://localhost:631/printers/), which has never worked for me before, and was able to add the printer successfully, and get it to print. Although I don't prefer the web interface, at least it's working. That makes me *suspect* that it's not CUPS itself, but KDEPrint. Is this totally wacky?

[edit]

OK, once that was set up (admittedly, it was set on LP/LPR print system via the web interface), I can now go in and change settings via KPrint. I can even change from LP/LPR to CUPS now. I don't get it, but I can live with it. Maybe this will help someone else. Hopefully, it'll get fixed soon Winken

I use Mepis and kanotix and can confirm that the fix posted above worked for me, and printing still works after reboot.

markb - 13.06.2006, 01:02 Uhr
Titel: RE: Works now.. and I don

I've upgraded repeatedly and followed all the advice here but my print system remains dead. Everytime I enter the KDE printers section in control center it reports an error "Connection to CUPS server failed. Check that the CUPS server is correctly installed and running. Error: host not found". Changing the host field to localhost in Cups Server under Print Manager just gives a different error: "Connection to CUPS server failed. Check that the CUPS server is correctly installed and running. Error: the IPP request failed for an unknown reason". Trying to configure the Print Server results in an error popup complaining about a heap of configuration options not understood by kcontrol. It just seems that something is horribly now broken between cups and kde? I don't understand how this can get broken in sid for so many days and not get fixed by now?

I tried to configure my printer directly pointing my browser at localhost:631 but the dialog prompts me for "cups" user password which does not look right? And configuring the printer outside of KDE can't be a proper solution.

Have the rest of you all got your printers going again?

clubex - 13.06.2006, 01:50 Uhr
Titel:

markb I have similar reports when attempting to print after a cold boot.

The only remedy I have found is to reinstall the printer driver and restart the
server. I have to do this after every reboot.

I've examined all the CUPS config files after a reboot (ie printer won't work)
and after reinstalling the driver (ie. printer works) and can find no difference
between them.

BUT MOST SIGNICANTLY I have observed that after a reboot I have no
/dev/lp0 but after reinstalling the printer driver I find that a /dev/lp0 has been
created.

Although I have a permanently connected parallel port printer I suspect a problem
with udev.

I think I've tried everything here and no success. I have seen that same message from kprinter. I don't usually use KDE so I tried configuring everything from the web interface for cups. I logged in as root. I can remove and install printers. Everything looks fine until I try the "print a test page". It queues the page and changes the status to "printer is offline".

I was able to print a postscript file with a rather long command line that bypassed cups.

I have tried dist-upgrade twice. Once leaving the old cups conf and the second time allowing the cups conf to be updated. I have tried purging cups and then reinstalling. No luck.

I have reinstalled a partition image I made before my latest "dist-upgrade" and I can print again using the old cups. Of course this ends dist-upgrades for me until this problem is solved. It is rather frustrating but I guess Debian unstable is just ... unstable.

This isn't a general issue. My experience starting with 2005-04 and dist-upgrading most days :

1. Set up printers after installation
2. In March foomatic files changed and unable to 'find' any Samsung printer via localhost:631 but can find it through kde print manager
3. In May, localhost:631 finds some Samsung printers but not mine
3. In May, kde print manager disappeared from menu but can still get to it via control centre
4. In June, first CUPS changes - had to delete and reinstall printers
5. Second CUPS changes - had to delete and reinstall printers as the CUPS means of assignment changes; at this stage I need to have a printer switched on in order to add it (no more usb1, usb2 . .)
6. kde print manager appears back in the menu in one of the kde upgrades

Currently, no print problems at all with my 2 USB printers.

Is the ongoing print problem associated with the starting point? Mine was 2005-04; is it starting with Easter-RC4 or Cebit that's causing the problems? Or, as just noticed on another thread, is this just a parallel port printer problem?

Yep. My file had both those lines active. I commented out the file socket but it made no difference.

To drb, mine is a clean Easter RC4 install updated frequently since in the normal manner. I remember the Printer menu item disappearing but have not had an actual problem with my (parallel) printer until a few days ago after an update. Seems to me cups has changed in some new way which KDE needs to re-negotiate?

Anyone have a quick rundown on auto loading kernel modules before I start googling?

Not just parallel port: my USB printer does not work. problem seems to be cups or maybe KDE. actually, i have a multifunction scanner/printer and while the printer function does not work and i get cups errors (see my post above) - the scanner function OF THE SAME UNIT (epson cx3200) works fine.

As for starting point: my starting point is Easter-RC2, but I use an older kernel (2.6.15-6-kanotix-1) due to wireless compatibility issues. I dist-upgrade about every day or two.

I've solved my problem.

I purged cups and reinstalled all packages removed. I am using the new cupsd.conf file.

I turned on debug and looked through the cups error log file. Googling on "LPGETSTATUS returned a port status of 08", I found this forum thread:

http://www.easysw.com/~mike/cups/str.ph ... C0+I0+E0+Q

I couldn't get cups to accept this uri type. So I hand edited printers.conf replacing the "usb://MINOLTA ... blah .. blah" DeviceURI with "file:/dev/usb/lp0".
(Note: only one slash after the "file:") "/dev/usb/lp0" is the location of my USB printer.

I'm not sure why this works but I hope this helps others.

I'm still stuck. This is especially annoying because the printer did work for one evening after following hubi's instructions. Then I turned the machine off for the night.

What I have: kanotix 2005-4 dist-upgraded several times a week; Epson Stylus Color 640 on parallel port.

What I have tried:

- Uninstalling/reinstalling the printer - nothing.

- Changing printers.conf line to DeviceURI file:/dev/lp0 didn't work - cups died.

- Creating lp0 with modprobe only added a few new lines to my cups error-log complaining that it could not open /dev/lp0, permission denied.

Maybe the best thing to do is go all the way back and reinstall cups again, follow hubi's directions and take better notes this time?

I think that's the best course to take. I rarely turn my computer off or reboot. Unlike Windows where I was constantly rebooting for some reason or other. I would apt-get remove --purge cupsys first, then follow clubex & hubi's suggestions. I finally got mine to work this way, although I've been afraid to reboot again to see if the changes stick.

I admittedly don't know that much, but it seems to me that unless there is a specific feature that a new kernel provides, I don't see any advantage to upgrading it. It is a temptation to have the "latest & greatest" which can sometimes be more trouble than it's worth. The kernel, as I understand things, just provides an interface between hardware & software (GUI) & if things are goin OK, I wouldn't recommend messin with a good thing. I've learned this the hard way, but like I say, I'm certainly no expert on these matters. YMMV. Linux shouldn't have to be rebooted several times (like Windows) for changes to take effect, at least in my experience, so that's why I was kinda suprised that I had to do a reboot to fix this printer problem. I'm still nervous about doing a reboot, cause I'm tired of messin with this thing. At least it's workin now. Smilie

I guess I'm "old school" - where if you're not using something, whether it's a TV, computer, or desk lamp, you turn it off. I don't leave my computer on just to burn electricity. And if the settings don't "stick" after booting back up, then they were never really fixed, IMO.

Anyway, I hope my printers.conf file can help someone solve their CUPS problem.

For people with the newest cupsys-1.2.1-3 I edited my method (which is actually horo's) on page one.

The line to comment is now in /etc/cups/cupsd.conf.
