CUPS - unauthorized to manage


Hello,

I'm trying for three days now to get my printer running (parallel, desk-jet).

I'v read a lot about configuring CUPS by now, but still have authorization problem.

The web-page is running, both locally as on a windows-box (the latter took me some time editting the cupsd.conf file, I'm just not sure what did the trick).

But I can't for example add a printer, kill jobs etc. (I added a printer with the command-line, which wasn't a problem!)

I'm starting the web-page as root locally, the windows-box doesn't ask me to log on.

Reading the conf-file, I think there's something wrong with groups - users, but can't figure out what.

Does anybody have a clue?

The cups administrator isn't the same thing as root, its a separate account.
As root type the following
Code:
lppasswd -a username
where 'username' is the name you want to give the cups admistrator. This will then prompt you to enter a password for the account. You should now be able to manage cups by going to your file manager and typing ://127.0.0.1:631 in the address bar.

Thanks for reply.

Didn't work out, got a message that some password file doesn't exist.

Got one step further. The docs said that root did have to have a password. otherwise you can't add printers. After commenting some lines in the conf-file, I can add printers using the web-interface (but still can't use the other options).

At last, I connected the printer to an XP-box, so at least I can print. When having more time, I will give it another try.


To me the conf file is a bit confusing. I don't know what defaults are activated, for example:

# Cup can do x left or right.
# Default is right.

# x = right.

I expect that when uncommenting nothing, CUPS will do x to the right. But I assume you have to uncomment the line? But if you don't uncomment the line, what will CUPS do, go to the middle?

The line that determines admin access to CUPS is this one (in /etc/cups/cupsd.conf):
Code:
#SystemGroup sys
Meaning that if you add yourself to the "sys" group, you will be able to use your own account and psasword to administer CUPS.

Adding yourself to "sys is as easy as running
Code:
vigr
, look for the line that starts with "sys" and add your name at the end of the line.

Or, if you don't like hacking the group file that way, run this command (substitute yourusername with your own user name of course :-) :
Code:
usermod -G $(id -Gn yourusername | tr ' ' ','),sys yourusername
You need to logout and login again to have this effect.

Eric
