CUPS: Username and password.

aliiscool · 06-17-2004, 01:38 PM

Hi, I've been trying to get this shitty little Lexmark z25 printer my mom bought to work but when i install cups and try to configure everything using their web interface, they ask me for a username and password but i dont know where i would go to configure that..i try my root information but that doesnt work, and none of my other system passwords work. help this is prolly a really simple answer. thanks in advance.

If "their webinterface" refers to http://localhost:631 then
the root account should work. If it doesn't I have no clue how
you may have screwed up.

Cheers,
Tink

What error do you get? Forbidden?
Make sure your address is localhost:631 and not something like 10.0.0.1:631

i get no error, it just continually keeps asking for logon again and again.....

Actually, it may or may not be a simple answer. It probably is, and I've seen this exact question posted in forums all over the Internet, but I've never actually seen anyone who solved the problem post what they did to solve it. Maybe you changed something in the configuration file? I googled for this problem and found this high up on the search results. It's a thread from some the debian site...

That makes sense, and also works.

Thanks for taking the time to explain this to me.

I would pay particular attention to the last 2 paragraphs. That seems like where your problem lies. Good luck!

I was having this exact same problem, I was able to get to the cups main screen but it would constantly ask me for the username and password. after reading the previous post I decided to check out the /etc/cups/cupsd.conf, I changed it to say:
## Anonymous access (default)
AuthType None
AuthClass Anonymous

the AuthType was commented and the AuthClass didn't exist there (I copied it from the same file though).
then I commented the lines:
#AuthType Basic
#AuthClass System
under the <Location /admin> heading at the very bottom.
after restarting cups i was able to get my printer up and running but the admin button no longer seems to work. maybe if I play with it enough I can figure it out.

may be some one who already had cups working could post there cupsd.conf file so we can check the differences.

==============
apparently I was wrong when I earlier said that the admin stuff was no longer working. after setting up the printer and doing a test page I went back to the admin section in the cups page and it let me log in with out a problem and seems to be fine now.

I realise that this thread is a month old now, but since I came across it looking for an answer I thought I'd post how I got this working.

I also realise that my solution is a total hack - but it worked, and I didn't have time to fiddle since I needed printing to work NOW.

it also means that the people who posted about access entries in the /etc/cups/cupsd.conf are totally correct (but the changes suggested didn't help me - but I was in a rush - maybe I did something wrong)...

so here's what I did...

Code:

# mv /etc/cups/cupsd.conf /etc/cups/cupsd.conf.suse (as I am using a newly installed suse system)
# cp /path/to/other/gentoo/etc/cups/cupsd.conf /etc/cups/cupsd.conf.gentoo
# ln -s /etc/cups/cupsd.conf.gentoo /etc/cups/cupsd.conf

# ls -l /etc/cups/cups*

lrwxrwxrwx    1 root     root           17 Jul 16 08:55 cupsd.conf -> cupsd.conf.gentoo
-rw-r-----    1 root     root        21184 Jul 16 08:54 cupsd.conf.gentoo
-rw-r-----    1 root     root        21318 Jul 16 08:54 cupsd.conf.suse

so as you can see I just copied a working config file from another distro - but the important thing to note is the names I gave them - so 6 months later when I revisit the files I will know exactly what I did, and can comb through them looking for the important differences - and the active cupsd.conf can easily be switched between them by using a symbolic link... so... NEVER DELETE YOUR DISTROS OWN CONFIG FILES... just in case... and be sure to add reminders to yourself when you do introduce 'foreign' files from another distro. it can only help later when you have forgotten what you did

P.M. me if you want a copy of the gentoo file. but you can prob find a working config if you look around, now that we know it's just that causing the prob.
