[sane-devel] How to configure sane, xsane, etc.
Wed, 9 Jun 2004 10:22:48 +0200
I am facing a big problem with xsane from fedora C1. (xsane-0.91-1):
1- I have a scanner Nikon LS-2000. The first person who ran xsane was not root
and it now impossible to change the owner and right of the device /dev/sg0.
This device has been set with owner didier and group root with permissions 600
and whatever root can do to change this is destroyed by the next use of xsane:
ownership, group and permission are reset as previously defined!!!! So nobody
but didier can use xsane and the scanner!
man sane-scsi :
When using a SCSI scanner, ensure that the access permission for the
generic SCSI device is set appropriately. We recommend to add a group
"scanner" to /etc/group which contains all users that should have
access to the scanner. The permission of the device should then be set
to allow group read and write access. For example, if the scanner is
at generic SCSI device /dev/sg0, then the following two commands would
set the permission correctly:
$ chgrp scanner /dev/sg0
$ chmod 660 /dev/sg0
This is now impossible to do! Where are the configuration files responsible for
this awful behavior?
2- Even for didier the use of xsane is not easy: every time he asks for xsane he
has to accept the license and to wait about 10/15 minutes for the research of
peripherics.... And, worse, he has to wait also if he wants to use gimp: gimp
hangs on xsane plug-ins....
I would like to understand how this can happen and how to corrct this windows
like behavior: unix systems were done for many users, it is more and more
difficult to use them like this.
Thank you for attention.
