Hello.
I try to allow a user on a local FreeBSD 4.6 workstation to mount its
own CDROM/DVD.
It is not suitable to allow mounts via root access, so I thought AMD
cpuld be the best solution.
I'm really new to amd and therefor I appreciate any hint or tip.
My primary intention is to allow a simple CDROM mount by a user by
inserting the CDROM and dismounting the CDROM after a while of inactivity.
I found a lot of stuff in the newsgroups, but I haver some trouble in
understanding what amd tries to do.
It seems, that a device mount is only possible via the type:=program
option, but this does not work due to the fact I misunderstand how amd
tries to mount the device.
I have installed a simple standard /etc/amd.conf with this mapping row:
# DEFINE AN AMD MOUNT POINT
[/amd]
map_name = amd.map
The appropriate amd.map file is located in /usr/local/etc/amd/amdmaps
and contains the following:
/defaults host==stud09;opts:=ro,grpid,nosuid,intr,utimeout=12000
cdrom fs:=/cdrom;dev:=/dev/acd0a;type:=program;\
mount:="/sbin/mount -t cd9660 -o ro /dev/acd0a ${fs}";\
unmount:="/sbin/umount ${fs}"
cdrw fs:=/cdrw;dev:=/dev/acd1a;type:=program;\
mount:="/sbin/mount -t cd9660 -o ro /dev/acd1a ${fs}";\
unmount:="/sbin/umount ${fs}"
Intention is to mount CDROM on /cdrom when accessing /amd/cdrom. But
this seems to fail with an (Operation not permitted) failure message.
Can anyone help or has a fast solution for those problems?
Thanks.
