[SOLVED] Denied permission to resume printer (pcLinux)

Jerb44 · 04-09-2020, 04:53 AM

Cups is demanding a username and password in order to resume a printer. I've tried both my basic login and root passwords (although I had to assume root username = basic login version). Neither worked....help please.

(OS updated yesterday)

The CUPS admin group(s) is/are defined in /etc/cups/cups-files.conf and privileges for various actions defined in /etc/cups/cupsd.conf

Did you try username "root" and the root password?

More info

Code:

man cups-files.conf

Code:

man cupsd.conf

You can get the current printer name(s) and status using...

Code:

lpstat -p

Then re-enable using...

Code:

su -c "cupsenable printer_name"

The root password should always work with cups. Your own login and password should work if you are in the cups admin group (usually called lpadmin but you can check the actual name by listing /etc/group)

I have noticed that some builds of cups stop giving you the option to log in if you once give a bad password. You have to reboot to get around that.

I'm not a PCLinux OS user, but cups-files.conf should contain an entry like this

Code:

# Administrator user group, used to match @SYSTEM in cupsd.conf policy rules...
# This cannot contain the Group value for security reasons...
SystemGroup lpadmin root

As long as your user account is a member of one of those groups, you should be able to use your regular user credentials.

Thanks everyone you have solved my problem which turned out to be that I didn't know that the userid for root is root!!!
You can all now confirm that I am a genuine Newbie.
