Using K3b with FreeBSD
K3b is a great CD/DVD authoring software. This small tutorial explains how to use it with non-root user accounts. This HOWTO is also applicable if you want to get k9copy working. You can skip setting SUID flags in this case.
First, let’s check whether you have to do anything about your kernel
setup at all. Execute
camcontrol devlist in a terminal. If
you see your CD/DVD writer, all is well. For example, this is the output
of the command when being run on my good old Thinkpad R50e:
/home/bastian % camcontrol devlist <MATSHITA DVD-RAM UJ-830Sx 1.00> at scbus1 target 0 lun 0 (pass0,cd0)
If you don’t see your hardware, let’s try something else: This is as
easy as it gets: Either add
/boot/loader.conf or compile a new kernel that contains
This should do the trick.
You need to set the proper permissions for the CD/DVD drive. If you look
at the output from
camcontrol devlist from above, you will
notice the part
(pass0,cd0). If you have multiple CD/DVD
drives in your computer, the numbers will be different. Substitute the
correct numbers for your system in the lines below.
/etc/devfs.conf and add the following lines at a
# Allow CD/DVD authoring perm cd0 0660 perm pass0 0660 perm xpt0 0660
If you are the only user of your computer, simply add your account to
operator group (which owns the devices by default).
If you want to enable burning for
multiple users, however,
I would strongly suggest creating an appropriate user group (e.g.
burn) and adding the user accounts that are allowed to burn
CDs/DVDs. In this case, in addition to the lines from above, the
following lines should also be added to
own cd0 root:burn own pass0 root:burn own xpt0 root:burn
Set SUID flags
Skip this step if you are trying to install k9copy.
I don’t like it very much, but is necessary to endow
cdrecord with root permissions. So,
root and execute:
chmod u+s /usr/local/bin/cdrdao chmod u+s /usr/local/bin/cdrecord
sysctl hw.ata.atapi_dma to check whether DMA is
enabled for CD/DVD drives:
/home/bastian % sysctl hw.ata.atapi_dma hw.ata.atapi_dma: 1
If the output is
K3b or k9copy should work now. If you want to enable user mounting of
