Hi, list readers...
[Please email me directly, because I'm not on the list due to technical
problems]
I experienced the following:

dirk@infinity:~ >ls -l /dev/sr0
brw-rw-rw- 1 root root 11, 0 Jun 4 1996 /dev/sr0

As root, I can run scsiinfo -i /dev/sr0 without any problem. What is my
mistake? What mode should the device file have to answer correctly to
INQUIRY commands? I tried another program that issues an INQUIRY
command, and as "dirk" it failed on /dev/sr0, but as "root" it worked.
how can I issue an INQUIRY command as "dirk" ?
I'm using Linux 2.0.31 without any patches or additional drivers. The
low-level SCSI driver is ncr53c8xx (825 chip).
