Hi,
[LM7.2]
So far, I'd been quite happy with CUPS; but now I'm denied access... Sorry for
the gory details; but I'm trying to get to the bottom of this quickly...
Yesterday, I needed to print some financial docs and discovered that my HPLJ5MP
decided to quit working. After tearing the printer apart countless times while
troubleshooting, I finally found the problem: a hairline crack in the power
motherboard... Fixed that and decided to check MandrakeUpdate... it lists a
security update for cups, so I tried to install it; but the install failed with
a screenfull of dependency issues.
OK, forget that and just print my stuff... AAAAAARRRRRRGGGGHHHHHHHHHHHHHHH!!!!!
Now, CUPS wants a userid/password..!! I never set one, or have any idea what
it expects.
Using qtcups and kups, I see what appears to be a clue: root (no password)!!
I have two desktops, each with a printer, so... check the other system... looks
the same; but that one WORKS.
Right now, I can't access http://localhost:631 either 'cuz it wants a password
too. OK, try via the other system... I can access cups via http there; but
when I select the printer on the main system, I get:
> Forbidden
>
> You don't have permission to access the resource on this server.
I've tried a lot of things including removing /etc/cups/certs/0. I was able to
change some settings via kups & qtcups; but nothing lets me fix it.
WORSE: hitting Cancel on the password dialog just brings up another (loops).
Restarting CUPS each time I try something, I even had one situation where the
password dialog appeared twice! Any attempt with Cancel just kept throwing 2 in
my face.
When trying a simple print, the auth. dialog defaults to my userid, so I click
OK; then I'm asked for a password, I enter it and click OK. It hangs at this
point with the following strace output:
> write(5, "8\1\4\0\2\0\300\2\0\0\10\0\0\0\0\0;\3\5\0\2\0\300\2\0\0"..., 176) = 176
> select(6, [5], [], [], NULL) = 1 (in [5])
> ioctl(5, FIONREAD, [32]) = 0
> read(5, "\3 \206\1\232\372\307\311-\0\0\0\6\0\300\2\0\0\0\0\t\1"..., 32) = 32
> ioctl(5, FIONREAD, [0]) = 0
> select(6, [5], [], [], NULL) = 1 (in [5])
> ioctl(5, FIONREAD, [32]) = 0
> read(5, "\2$\206\1\1\376\307\311-\0\0\0\6\0\300\2\0\0\0\0\t\1\307"..., 32) = 32
> ioctl(5, FIONREAD, [0]) = 0
Ctrl+c this print command (<simple script to generate envelope> | xpp).
Even trying via lpr gives:
> $ envelope Addresses/PF | lpr
> Authentication required on localhost
> Password: Username (leave blank to cancel):
^^^^^^^^^^^^^^^^^^
and this seems weird.
Some logs:

Sorry for the random rambling... my mind is getting warped trying to figure out
what happened... fixing the hardware was challenging enough...
I was starting to suspect a partial update; but "rpm -V" shows only
/etc/cups/cupsd.conf and /etc/cups/printers.conf "changed". printers.conf has a
date of Jan 2 18:45:39 2001, so I doubt it's the problem. That leaves:
/etc/cups/cupsd.conf contains (minus comments):
ServerAdmin [EMAIL PROTECTED] <--added after the problem started

Any help would be greatly appreciated.
