Problem with cups (cupsd and admin.cgi hang)
Hello,
i have Problems when i want to add a Printer, the command line tool and the web
interface will not work. After pressing the button where you can choose the printer,
the admin.cgi hangs with about 30% CPU-Time and cupsd needs about 60% CPU-Time.
While booth are hanging, cups fills then file /var/log/access.log permanently with
the entry:
name - root [tt/mm/yyyy:hh:mm:ss +0200] "POST /admin/ HTTP/1.1" 401 0
An strace shows that admin cgi want's permanently to add the printer and
then cupsd refuses it. Here a part from the strace which seems to be repeated all
time:
getpid() = 7179

send(2, "\3", 1, 0) = 1
recv(2, "HTTP/1.1 401 Unauthorized\r\nDate:"..., 2048, 0) = 376
An other curiuos thing is that I have to comment out all entrys
like:
Order Deny,Allow
Deny From All
Allow From 192.168.0.* 127.0.0.1
in the cupsd.conf. Otherwise the box where you
can select the interface for the printer in the web-form is
empty.
Any help needed.
Thanks
Michael
