Quick CD recorder software question

shassouneh · 06-19-2002, 04:29 PM

Hi All,
just wondering how I can use software such as KOnCD, XCDRoast, Eraoster etc... as a regular user (NOT root). For example, If I try to run XCDRoast as a regular user, I get:

Code:

samer@suse:~> xcdroast

** WARNING **: The X-CD-Roast wrapper seems not to have the correct
         permissions set

** WARNING **: So do as root something like that: (and read the Manual)
         chown root:cdwrite /usr/X11R6/lib/xcdroast-0.98/bin/xcdrwrap;
         chmod 2755 /usr/X11R6/lib/xcdroast-0.98/bin/xcdrwrap

samer@suse:~>

Note that I tried the two steps it mentioned above, but no dice. It complained about the first step as such:

Code:

samer@suse:~> chown root:cdwrite /usr/X11R6/lib/xcdroast-0.98/bin/xcdrwrap;
chown: `root:cdwrite': invalid group
samer@suse:~>

Any ideas please?

You have to create the new gorup cdwrite before you change ownership. see "man groupadd" for info.

I created the cdwrite grup, then changed the permissions as the error had told me. Now it complains about no uiid bit or something!!! Also, it complains about not being able to scan the IDE/SCSI bus due to failed permissions. Here is the output I get from the console:

Code:

samer@suse:~> su -
Password:
suse:~ # chown root:cdwrite /usr/X11R6/lib/xcdroast-0.98/bin/xcdrwrap;
suse:~ # chmod 2755 /usr/X11R6/lib/xcdroast-0.98/bin/xcdrwrap
suse:~ # exit
logout
samer@suse:~> xcdroast

Now you have to do the same chown command to cdrecord, mkisofs, readcd and cdda2wav. These are the true programs used to create cd's under linux, they are command line programs and xcdroast is only a GUI to these four programs.

I know. But please read above. It won't even LET me run XCDROAST as a regular user (samer).Please read my code section above that contains the feedback form the console.

cdrecord is the program that scans the scsi bus and does most of the work when writing a cd, unless you add it to group cdwrite you wont be able to write cd's as a user.

check the permissions on cdrecord, mkisofs, etc
it should contain a suid bit (hint ls -l /path/to/cdrecord it should return -rws--x--- 1 root group size modification_date /path/to/cdrecord or similar, note s in permissions field)
and did you ran xcdroaster as root first? You must run it as root to create global configuration file. Run setup in xcdroast options. Then you can use it as a regular user.
