Description Rumba 2004-07-08 05:21:00 UTC

I haven't been able to print for a while. CUPS would just segfault when I tried to login to the admin pages. A friend of mine had the same problem and after disabing all the use flags CUPS was using he got CUPS working again.

After some investigation I fount out the USE="-pam" "fixed" the segfault. I then remembered that I was using pam_usb. After commenting out the pam_usb line from my system-auth cups ran just fine even with the pam useflag turned on.

I don't know if this is a CUPS problem or a pam_usb problem. I you need any more information, please ask and hopefully I can help.

kind regards,


Reproducible: Always
Steps to Reproduce:
1.emerge cups with at least the pam useflag turned on
2.emerge pam_usb
3.Add the following line to your system-auth:
auth       sufficient   /lib/security/ check_device=-1
4 Go to the admin page on localhost:631
5 Go to "Manage Printer"
6 Click "Add Printer"
7 Type in your login name and password

Actual Results:  
At this point CUPS segfaults 

Expected Results:  
Let me manage my printers

You shouldn't be using pam_usb for CUPS authentication.

Anyway, could you try the lastest version of pam_usb (0.3.1) which I pushed
to CVS about 10 minutes ago ? (It's keyworded ~x86).

This release mostly fixes memory management.
