cdrdao: [NO] COPY PERMITED

stf92 · 09-21-2011, 09:59 AM

Hi:

I'm trying to use cdrdao. But the output TOC file contains the line

NO COPY PERMITED

I find that the only way, using cue2toc/cdrdao, to avoid this is editing the CUE file and painstakingly inserting 'FLAGS DCP' lines, one for every track.

True, a script may be written to insert the necessary lines. But this script won't be as trustworthy as cue2toc/cdrdao working alone. Is there any workaround?

From CHANGES_AND_HINTS.TXT:

Quote:

If you have permission errors when attempting to burn a cdrom or dvd image,
such as the following:
/usr/bin/cdrecord: Operation not permitted. Cannot send SCSI cmd via ioctl
then cdrecord almost certainly needs root privileges to work correctly.
One potential solution is to make the cdrecord and cdrdao binaries suid root,
but this has possible security implications. The safest way to do that is
to make those binaries suid root, owned by a specific group, and executable
by only root and members of that group. For most people, the example below
will be sufficient (but adjust as desired depending on your specific needs):
chown root:cdrom /usr/bin/cdrecord /usr/bin/cdrdao
chmod 4750 /usr/bin/cdrecord /usr/bin/cdrdao
If you don't want all members of the 'cdrom' group to be able to execute the
two suid binaries, then create a special group (such as 'burning' which is
recommended by k3b), use it instead of 'cdrom' in the line above, and add
to it only the users you wish to have access to cdrecord and cdrdao.

Dear Sir: I doubt you've got the meaning of my question. It's not about recording, because that, I can do it. The sequence is this:

cue2toc -o CD7.toc CD7.cue
cdrdao show-toc CD7.toc

Code:

show-toc
              Print out a summary about what will be written to the CD-R.

In this summary, the line

COPY NOT PERMITED

appears.

In fact, I did run the above secuence as root, but with the same result as before. Thanks anyways for you post.

I think the only way to do it is to write a script to fix the generated toc.

That is what I was fearing. Unfortunately, I can't test the script in the statistically meaningful way GNU software is.
