[Gutsy] wodim does not burn while cdrecord does

Binary package hint: wodim

n gutsy:
$ wodim -version

*I first tried to burn using n-c-b or k3b, the burning process went flawlessly, but the resulting CD, once re-inserted appears as blank.

* Using the command line to burn with wodim does not fix the issue.
* burning with the left over version of cdrecord, burn without any issue and the resulting CD is correct.

finally, my cd/dvd drive is simply dying :s
Please disregard this bug.
closing it as invalid

wodim still does not work on Gutsy. It is not suid root, and by defaults, does not have access to CD drive.
cdrecord found in gutsy's multiverse is set suid root and works correctly. To make wodim work, one has to (permissions get reset after reboot because of using udev/hal) chgrp cdrom /dev/scd* AND chmod g+w /dev/scd*

Still, graphical tools using wodim (brasero and nautilus-cd-burner) claim there is no disk inserted (though CD/DVD writing is possible from command line!)

[Milan Bouchet-Valat (nalimilan)]

Is this still a problem for you? I think it's been fixed:
$ ls -l /dev/scd*
brw-rw----+ 1 root cdrom 11, 0 2009-01-23 11:53 /dev/scd0
Please report so we can close the bug, thanks!

Changing the device permissions is no option as it just introduces
unneeded security problems.

There is a conceptional bug in wodim that is causing the problems:
The people behind wodim did remove checks for the needed privileges
in the code. As a result, wodim is faling later with unspecific problems.
In order to be able to send all needed SCSI commsnds for CD/DVD/BD
writing, a software needs to have root privileges. Ignoring this fact causes
problems.

The original cdrtools installs cdrecord/cdda2wav/readcd suid root and this
is why the problem described in this bug report does not apply to cdrecord.

The best solution is to upgrade to recent original software from

ftp://ftp.berlios.de/pub/cdrecord/alpha/

compile and install (the latter as root).

[Milan Bouchet-Valat (nalimilan)]

I doubt people at the security team would rather run a tool as setuid root than setting cdrom group the required device files. And anyway, your personal feeling is completely out of scope here: wodim does not need setuid root to work, and now udev sets the right permissions AKAIK. We just need a confirmation that this has been solved for quite a long time.

Please stop advertising your product on our bug tracking system. There are reasons why Ubuntu/Debian have stopped shipping cdrecord and ranting everytime we're talking of wodim won't change those. You're spamming bug reports that were filed against wodim *and don't concern your project in any way*.

[Schily (schilling-fokus)]

I am sorry to see that you are uninformed about the need for root privileges
for writing CDs or DVDs. Your personal feelings are not aligned with facts.

Wodim is known to fail under many conditions _because_ is is not run
as root.

As wodim cannot be legally distributed (wodim is in conflict with GPL and
Copyright) please stop advertizing wodim.

[Milan Bouchet-Valat (nalimilan)]

I'm not advertising wodim but trying to clean fixed bugs in a distribution that relies on it. It's not up to me to decide upon wodim's distribution in Ubuntu, and bug reporters care even less about fantasist licensing issues. Please let the original reporter give his feedback, I won't read your posts anymore.

[Schily (schilling-fokus)]

The original reporter seems to use the original software with success.

If you believe that the related Ubuntu distribution relies on wodim, then
you have a problem because wodim cannot be legally distrubited.

If you like to reply, please do not again be impolite.....
