Where is Gnome Toaster?

Hi there,

You can burn CDs on SJDS via Nautilus.

Nautilus uses a program called cdrecord to burn the cds. To allow non-root users to be able to burn cds, the cdrecord program needs to run as root which normally only is the case when the root user launches the command. However, there are two ways to make "normal" users "fake" being root :

set the suid bit on the /usr/local/bin/cdrecord program like this :

chown root /usr/local/bin/cdrecord

chmod 4711 /usr/local/bin/cdrecord

This will make sure the cdrecord program ALWAYS is ran as root user. However, some people don't want to have programs run as root when not issued by the root user.

Another way to fake this "run as root" behaviour is to give a restricted group of people access to the cdrecord program like this :

groupadd cdburners

chown root /usr/local/bin/cdrecord

chgrp cdburners /usr/local/bin/cdrecord

chmod 4710 /usr/local/bin/cdrecord

To add a user to the cdburners group do this

usermod -G cdburners <username>

where <username> is the login name of the user. Please note that the groupflag is a capital G. Also please note that the above usermod command will make sure that the user ONLY is a member of its default group (users) and of the secondary group cdburners. If the user was a member of other secondary groups before it will not be anymore after issuing the above usermod command.

To find out all secondary groups a user is member of, login as that user and type

id -a

a sample output may be

uid=500(test) gid=100(users) groups=100(users),500(cvs)

so in this case the correct usermod command would be

usermod -G cvs,cdburners test

Please note that both methods for running cdrecord as root user are equally well and only one needs to be performed. The second one has more control over who can burn cds and who cannot but it involves more homework for the administrator.

I see the same problem too - nautilus-cd-burner can't find my DVD Writer. I'm using

cdrw -l gives

NodeConnected DeviceDevice type

-+--+--

cdrom0| PHILIPS DVDR1648P1P2.2 | CD Reader/Writer

I've looked at the man page for nautilus-cd-burner, but nothing there tells me how it might be forced to search for this device. I'm logged in as root, so I'm sure it's not a permissions problem.

Anyone have any ideas?
