Red Hat Bugzilla – Bug 191882
cannot manage all cups printers
Last modified: 2007-11-30 17:11:32 EST
Description of problem: I have a cups server managing some printers attached to another system, and printers attached to the server itself. If i start firefox on the server and try to manage the printers, the browser only show the printers attached to the other system: firefox localhost:631 Only if I use firefox on another machine (firefox cupsserver:631), then I see all printers (the local attached printers too) and can manage them. Version-Release number of selected component (if applicable): cups-1.2.0-1.1 How reproducible: Each time Steps to Reproduce: 1.firefox localhost:631 2. 3. Actual results: Only the printers attached to another computer are shown Expected results: All printers are shown Additional info: New behaviour in cups-1.2.0-1.1. Had no problems in cups-1.1.23-30.2
Please describe this problem in more detail. As far as I can tell, you have two separate machines: 1. 'localhost' (showing the problem) with printers locally attached and 2. 'cupsserver' with printers locally attached The problem you've described is that, on localhost, running 'firefox localhost:631' only shows printers locally attached to 'cupsserver', and does not show the printers locally attached to 'localhost' at all. Have I understood correctly? If so, what does 'lpstat -t' say when you run it on 'localhost'?
lpstat -t on "cupsserver" shows _all_ printers, the locally attached printers and the remotely attached printers. Additionally, I can't understand your argument that "localhost:631" shows only locally attached printers: If connecting via "localhost:631" and clicking the button "Administration" and then the button "Manage printers", I get _ALL_ printers, and not only the locally attached ones. Why, if connecting from another machine to "cupsserver", getting another table of printers than if connecting locally? This seems not to be reasonable. lpstat -t scheduler is running no system default destination device for cps: lpd://aix2/cps device for cps-a3: lpd://aix2/cps-a3 device for cps-fol: lpd://aix2/cps-fol device for d21asc: lpd://aix2/d21asc device for hp-a0: lpd://aix2/hp-a0 device for lj32350: socket://lj32350.rhrk.uni-kl.de:9100/ device for lpsc: ipp://lpsc:631/ipp device for lpsc1: socket://lpsc1:9100/ device for lpsc1d: socket://lpsc1:9100/ device for lpsc1f: socket://lpsc1.rhrk.uni-kl.de:9100/ device for lpsc1t: socket://lpsc1.rhrk.uni-kl.de:9100/ device for lpsc2: lpd://lpsc2/lpsc2 device for lpsca3: ipp://lpsc:631/ipp device for lpscbb: socket://lpsc1:9100 device for ps: lpd://aix2/ps device for ps-a0: lpd://aix2/ps-a0 device for ps-a3: lpd://aix2/ps-a3 device for ps-eins: lpd://aix2/ps-eins cps accepting requests since Tue May 16 10:55:47 2006 cps-a3 accepting requests since Tue May 16 14:23:05 2006 cps-fol accepting requests since Tue May 16 14:20:17 2006 d21asc accepting requests since Tue May 16 14:17:04 2006 hp-a0 accepting requests since Tue May 16 14:28:51 2006 lj32350 accepting requests since Tue May 16 10:55:47 2006 lpsc accepting requests since Tue May 16 14:40:18 2006 lpsc1 accepting requests since Tue May 16 14:41:11 2006 lpsc1d accepting requests since Tue May 16 10:55:47 2006 lpsc1f accepting requests since Tue May 16 10:55:47 2006 lpsc1t accepting requests since Tue May 16 10:55:47 2006 lpsc2 accepting requests since Tue May 16 16:20:59 2006 lpsca3 accepting requests since Tue May 16 10:55:47 2006 lpscbb accepting requests since Tue May 16 13:53:49 2006 ps accepting requests since Tue May 16 14:05:12 2006 ps-a0 accepting requests since Tue May 16 14:24:54 2006 ps-a3 accepting requests since Tue May 16 14:15:17 2006 ps-eins accepting requests since Tue May 16 14:26:07 2006 printer cps is idle. enabled since Tue May 16 10:55:47 2006 printer cps-a3 is idle. enabled since Tue May 16 14:23:05 2006 printer cps-fol is idle. enabled since Tue May 16 14:20:17 2006 printer d21asc is idle. enabled since Tue May 16 14:17:04 2006 printer hp-a0 is idle. enabled since Tue May 16 14:28:51 2006 printer lj32350 is idle. enabled since Tue May 16 10:55:47 2006 printer lpsc is idle. enabled since Tue May 16 14:40:18 2006 printer lpsc1 is idle. enabled since Tue May 16 14:41:11 2006 printer lpsc1d is idle. enabled since Tue May 16 10:55:47 2006 printer lpsc1f is idle. enabled since Tue May 16 10:55:47 2006 printer lpsc1t is idle. enabled since Tue May 16 10:55:47 2006 printer lpsc2 is idle. enabled since Tue May 16 16:20:59 2006 printer lpsca3 is idle. enabled since Tue May 16 10:55:47 2006 printer lpscbb is idle. enabled since Tue May 16 13:53:49 2006 printer ps is idle. enabled since Tue May 16 14:05:12 2006 printer ps-a0 is idle. enabled since Tue May 16 14:24:54 2006 printer ps-a3 is idle. enabled since Tue May 16 14:15:17 2006 printer ps-eins is idle. enabled since Tue May 16 14:26:07 2006
Please describe in more words what your problem is exactly. I don't think I have understood. Is it that you see different printers when doing these things?: 1. using 'firefox localhost:631' on the 'cupsserver' machine 2. using 'firefox cupsserver:631' on any other machine Is that the problem you are describing?
Hi, the problem was another one (I found out after some experimentation): The cups browser interface shows only such printers, for which no restricted access is set by the command "/usr/sbin/lpadmin -p <printer> -u deny:all -u allow:<userlist>". If I remove such restrictions by hand from /etc/cups/printers.conf, then _ALL_ printers are shown and can be administered.
Okay, I see that here too. Reported upstream: http://cups.org/str.php?L1700
Found a workaround: 1. browser start with cupsserver:631 2. Press the tab administration 3. login via ""426 Upgrade Required" 4. Press "manage printers" -------> Shows _ALL_ printers
I think this has been fixed upstream. 1.2.0-1.4 does not contain the fix, but the next cups package I build after that will.
Please try 1.2.1-1.2 from here: http://people.redhat.com/twaugh/tmp/cups-fc5/ Does it work correctly for you now?
Yes, it does. Many thanks. Regards Joachim Backes
