[sf-lug] lpadmin --> forbidden

[Alex Kleider]

Here's the output you asked about:


alex at lildell:~$ ls -l /dev/lp0
crw-rw---- 1 root lp 6, 0 2008-10-25 12:23 /dev/lp0
alex at lildell:~$ sudo strace -f lpadmin -p OfficeJet -v parallel:/dev/lp0 -m OfficeJet.ppd > trace 2          >&1
alex at lildell:~$ dmesg | tail

[  735.604043] ppdev0: unregistered pardevice
alex at lildell:~$

the strace command yielded in excess of 500 lines!
I have it captured if you think it'll be of use

by the way: I added the relevant users to lp group without any benefit.
