User acess for CD Writing

[gala_dragos]

Hi! I think this is another one of those black holes in linux documentation/usage. I wanna use my DVD-RW and CD-RW without being root, but guess what, YOU CAN'T . I've been searching with google "set CDROM permissions in fedora" and all the pages that appeared were about installing fedora from CD. LOL!!!!! So can anybody explain how to set up DVD-RW permissions so I can write CD's in user mode?

Really, I guess my Fedora 7 install must be broken then, as I can write CDs and DVDs just fine as 'Joe User' Maybe you need to give a bit more info.

It's simple: until now I've been using root to burn CD's, but now I am trying to burn as another user (not root) and it doesn't work. Program asks for permissions to sg0, sg1 and sg2 devices. There is no entry in fstab about those devices.

That's why I asked for more info. What version of Fedora, KDE or Gnome, What's the ID of the drive on the BUS, what burning program you're using?

I had similar trouble with GnomeBaker, it automatically set the drive as device sr0 in its preferences and would throw up errors when trying to burn, but the drive is really scd0. It could be something as simple as changing the device name.

Fedora7, KDE interface, burning software: NERO for Linux 3

k3b complains that cdrecord and cdrao should be run with root permissions

[a_small_cake]

I never use root for burning cd/dvd. My user can do that without problems.

[gala_dragos]

Is it just me? Or I'm the only one having this problem?

Check the "Don't show this message again" box and k3b works without problems.

[gala_dragos]

how about making nero to run in user mode? anybody knows how to change permissions for those devices?
why nero? because k3b gives me only maximum burning speed for DVD and I don't wanna burn at 18x.

[LocutusOfBorg]

No experience with nero here, but when it comes to device permissions I use a custom set of udev rules so that my optical drives are always 666.
With K3b you can select burning speed in the "burn" dialog (instead of "auto", choose what you want); as for the root permission for cdrdao/wodim, if you have k3bsetup it can do it for you - otherwise you can set them suid root manually.

EDIT, sorry, I didn't see your other thread about speed - but maybe it is related to the permission issue... can you set the speed as root?

[gala_dragos]

no I can't set speed as root. This is valid only for DVD disks, CD disk have no problems. I only get three speed options with DVD disks: Auto/Ignore/maximum_medium_supported_speed. That is if In put an 8x DVD I get 8x DVD write speed there, and if I put 16x DVD I get 16x DVD write speed.

[gala_dragos]

You were right about permissions! I've set all sg devices with 666 and it works.

[gala_dragos]

from where do you download k3bsetup?

[LocutusOfBorg]

It's part of K3b, but the fedora version is built without it. You can rebuild the srpms, if you want it.
