I installed SuSE 10.0 using 5 cd's and I have a problem adding a printer.. I try to add a printer using cups and when I get as far as add printer, I log in as root and give the password I gave when installing SuSE 10 and get an error message "authentication failed". I use the same password to log is as root in xterm and on command line, no problem, successful logon. Why can't I log in to install a printer using cups? jozien

because root cannot access the print_system man lppasswd will give you the directions lppasswd -a <username> then install a printer. -- Patrick Shanahan Registered Linux User #207535 http://wahoo.no-ip.org @ http://counter.li.org HOG # US1244711 Photo Album: http://wahoo.no-ip.org/gallery2

Sometimes my emailer is smarter than me. Sorry for the direct email. Fedora Core (at least up to FC3) defaulted to root having access to CUPS Admin functions. I saw the man page on lppasswd; assuming root (and other superuser) privileges are properly protected, what does SUSE gain by not defaulting root to CUPS Admin functions? There aren't any other users in the digest that I could identify, so root (or someone) still needs to be added in order to be able to use CUPS' administrative functions.

It serves to annoy and confuse us newbies. As far as I'm concerned, the need for a CUPS admin should be turned off by default. I've already emailed Novell about this and displayed my displeasure at not having the ability to have the same password for CUPS as root on several NG's and forums. -- kai www.perfectreign.com linux - genuine windows replacement part

And not-so-newbies as well! The official answer as to why it is set up this way can be found here: http://portal.suse.com/sdb/en/2003/09/jsmeix_print-einrichten-90.html I think it would be nice if YaST had a button in the printer section to say "allow printer admin by root". That might be a secure but convenient compromise.

Nothing stops you having the same password. Just enter root and its password into the lppasswd command. Cheers, Dave

Indeed. There are several oddities in the SUSE printing setup that suggest it has not been designed for the real world of the everyday Linux desktop (eg replacing the KPrinter setup with the less capable YaST one, not having the ptal service start by default on a reboot even if it was set up by the install process, the CUPS admin user requiring a longer password than the root user so that you can't use the same one for both if you have chosen one for root that is shorter than the one CUPS wants, etc). Any comments you make seem to fall on deaf ears, so I don't suppose there's much point commenting. I just try to work around the printing shortcomings on an otherwise excellent distro. -- Pob hwyl / Best wishes Kevin Donnelly www.kyfieithu.co.uk - Meddalwedd Rhydd yn Gymraeg www.cymrux.org.uk - Linux Cymraeg ar un CD

Hmm...there seems to be a way to let CUPS admin = root. I'll try that.

That would work.

Nope. Doesn't work. On my systems and my mothers 9.2 system, the root and CUPS password are forced to be different. When I tried to use the root password on lppassword, I was denied. -- kai www.perfectreign.com linux - genuine windows replacement part

You can add as many "cups admins" as you want. I know of no limit.

The KDE print manager does have this as I use it for setting up -all- of my printers.
That would work.

I've yet to have an adequate explanation for this. In a networked environment, sure, you want to restrict users' access to the printer queues. However, in a workstation setup you want to allow full access, IMO.
I had no problem the the four 9.2 systems I setup, you must have a syntax error somewhere. It does allow the same password. Cut and paste this: lppasswd -g sys -a root and use the system root password. Once again it does work.
That's the command I used (after I googled it since it wasn't exactly obvious) when I setup my systems. For example on my mother's 9.2 system, her root password is 'bluelady'. When I tried to use that for CUPS admin, it denied me. Hence, her CUPS root password is 'bluelady2'. Fortunately, they're both listed on a sticky note next to her monitor, so she can easily remember. -- kai www.perfectreign.com linux - genuine windows replacement part

I think Kevin Donnelly probably came up with the answer:
the CUPS admin user requiring a longer password than the root user so that you can't use the same one for both if you have chosen one for root that is shorter than the one CUPS wants, etc).
I have a nice long root password :) Cheers, Dave
