Problem with CUPS

rit_netsys · July 27, 2011, 8:55am

I am facing two issues with CUPS -

I have installed cups 1.3.9 over OpenSuse11 x86. Please check below -

cups:/usr/share/cups/banners # cups-config --version
1.3.9
cups:/usr/share/cups/banners # cat /proc/version
Linux version 2.6.27.7-9-pae (geeko@buildhost) (gcc version 4.3.2 [gcc-4_3-branch revision 141291] (SUSE Linux) ) #1 SMP 2008-12-04 18:10:04 +0100

I have added few printers over there and everything is working fine. I can also able to add - delete - modify any printers from “yast2 printer” command. I can also able to browse cups web interface via http://cups:631, but when I am going to manage the printers (start - stop - delete etc), none of the buttons are working in firefox5 not even in IE also. Older version of firefox is giving error as “This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection.” All other buttons are working properly.

LINUX - LINUX Printing - OK
LINUX - WINDOWS Printing - OK
WINDOWS - LINUX Printing - NOT OK

While giving printing from Windows machine (Printer attached on Linux), there is no problem to coonect the printers, but unable to print.

Can anyone please help me out to resolve the issue? If any log or anything needed, I will provide the details.

You have openSUSE11 installed? That is well past the supported date. Is there a reason you’re not yet using 11.3/11.4? I can’t remember the CUPS version it used by default. How did you install CUPS? (By rpm,or compiling from source)?

This could well be to do with a mis-configured /etc/cups/cupsd.conf file (part of the CUPS RPM). The CUPS admin policies are set there.

Also posting the settings of cupsd.policy.conf -

If you would like to create your own policy, please do so in a different

include file and set the DefaultPolicy directive. Please do not forget to

verify your custom policies after an upgrade.
