CUPS username and password
 

Hi,

If if pull up http://localhost:631 and go to admin it ask for a username and password. I've tried my user account and root, but it doesn't seem to like either. Which username and password is it looking for?

Thanks in advance,
TC

Not a CUPS guru, but you might try looking in /etc/cups/cupsd.conf for some useful options.

It's looking for your root password.

The username should be exactly "root" and the password should be your normal root password.

That's what I thought as well. But it doesn't accept it!

Ok, here's whar I found in /var/log/cups/error_log:

E [13/Mar/2004:10:58:11 -0800] Unable to open /etc/cups/passwd.md5 - No such file or directory
E [13/Mar/2004:10:58:11 -0800] IsAuthorized: No matching user:group for "root" in passwd.md5!
E [13/Mar/2004:10:58:42 -0800] Unable to open /etc/cups/passwd.md5 - No such file or directory
E [13/Mar/2004:10:58:42 -0800] IsAuthorized: No matching user:group for "root" in passwd.md5!

ok, why is looking for passwd.md5?

ccin dunno if you're using Suse 9.0 but if you are then the CUPS password is an encrypted one. A search of their site will explain it all.

Yes, I am using Suse 9.0. I'll check it out. Thanks!

Here we go, link belwo shows you what to do.

After checking out that link, I discorvered I needed to run the following command:

lppasswd -g sys -a root

That did the trick. Thanks Chris!

root password is enough
 

When i was facing the same problem,

I used my

Username = root user name
password = root password

and it is working fine now!

Change some things in your /etc/cups/cupsd.conf file:

Change the authentication type to "None".
Remove any lines that have "@SYSTEM" in it.
Restart the CUPS daemon.

Thanks Geremia!

Your solution still works with CUPS 2.1.3 on Linux Mint 18.3.

I changed the authentication type to "None" and selectively commented out "@SYSTEM" references so as not to completely compromise security (i.e. a job can still only be cancelled by the owner or root).

I just enabled CUPS on my Slackware 14.2 system. I then connected via web browser to localhost:631. Under the "Administration" tab I clicked "Add printer", at which point it asked me for a username and password. I mistakenly entered my normal username & password instead of root's credentials. Of course it wouldn't let me perform any administrative tasks. The problem is that I can't figure out how to log out so I can log in properly as root. Does anyone know how to log out of CUPS?

Geremia's solution worked -- CUPS username and password
 

Geremia's solution worked. Thank you Geremia. You da man!

Been there, done that! Try just closing the tab and then closing the browser — that should give CUPS the message that you want it to quit, and then start over again.
