When I try to burn with K3B as user I get the following message:

ERROR: cannot open SCSI device '0,0,0': cannot open '/dev/sg0
ERROR: please use option '--device [proto:]bus,id,lun', e.g. --device

Where do I need to go to set this right?

Is your cdr/w or dvdr/w device mounted as a scsii device and is it device /dev/sg0?

It looks like k3b is trying to open your recorder and can't
It could be that you don't have your cdr/w mounted correctly.

You say as "user" does user have access permissions to burner?

look at
/etc/fstab
You'll have to bo root to modify it
su
password
open the file for editing

Read the man pages for mount

dmesg | grep ^hd
will show you the drives on your machine I think

hdparm -i /dev/sg0 will show you the drive info if it is at /dev/sg0

Just a few thoughts.
Post your fstab file and someone will help

Burner does burn in root

Cannot find any driver at /dev/sg0


This is my fstab file:

I think that /dev/cdrecorder is a symbolic link to another device. Execute the folllowing commands:
Now you will probably see that cdrecorder is a symbolic link to another device.

This is what I did. I created a 'burn' group, added my user to that group and gave the group access permission to my cdrecorder. I'm not really sure which permissions I've set on the device. I think 'read' permissions for the group are sufficient.

cd /dev
ls -1 | grep -i cd recorder
gives me
cdrecorder

I'm at home now (behind my Debian machine), so I'll see what I can do.

The command actually isn't "ls -1 | grep -i cdrecorder" but "ls -l | grep -i cdrecorder" (so that is -L, lowercase that is).

Could you try that command please. I'm almost possitive that "cdrecorder" is a symbolic link to another device.

This is what I get:

lrwxrwxrwx 1 root root 3 2004-11-27 11:45 cdrecorder -> sr0

OK, now we're getting somewhere

I think this 'sr0' is also a symbolic link (at least it is on my system ). I'll try to give you a complete walkthrough now, otherwise we'll keep posting messages

Again, the same command, but now a "grep -i" on sr0, so "ls -l | grep -i sr0". Do this "ls -l | grep -i" thing as long as it gives symbolic links to other devices.

On my machine, "ls -l | grep -i sr0" gives me:
lrwxrwxrwx 1 root root 4 Apr 12 2004 sr0 -> scd0

When I then do a "ls -l | grep -i scd0", I get:
brw-rw---- 1 root burning 11, 0 Mar 14 2002 scd0

Now, scd0 is a device and not a symbolic link (it doens't list a "->") to a device. Now create a group called "burning", add your user to that group.

Next, change the group of the device (in my case device scd0) to "burning". You can do this with the command "chgrp burning [devicename]", so in my case "chgrp burning scd0"

Next, change the permissions on the device. The command for this action is "chmod 660 [devicename]", so in my case "chmod 660 scd0". The 660 just says to give read & write permissions to the owner and group of the device and no permissions to "world".

If you have done everything right (just run that "ls" command again on the device, you should see the same output as me, except for maybe a different devicename), you're able to burn with your user account.

Good luck.

Here is what I did and got:

[user]@linux:/dev> ls -l| grep -i sr0
lrwxrwxrwx 1 root root 3 2004-11-27 11:45 cdrecorder -> sr0
brw------- 1 [user] disk 11, 0 2003-03-14 14:07 sr0
[user]@linux:/dev> chgrp burning sr0
[user]@linux:/dev> chmod 660 sr0
[user]@linux:/dev> ls -l| grep -i sr0
lrwxrwxrwx 1 root root 3 2004-11-27 11:45 cdrecorder -> sr0
brw-rw---- 1 [user] burning 11, 0 2003-03-14 14:07 sr0

But K3b still isn't working in user.
Since the ERROR message says "cannot open '/dev/sg0", shouldn't I be ending up with sg0 and not sr0?

Thanks for your patience!

Yeah, that's real strange

OK, I looked some more into it (I'm actually f&cking up my own system to see if I can get that error )

You did add your user to the "burning" group ??

Let's see. When you do a "ls -l | grep -i sg0", what kind of output do you get ??? It should be something like this (my cdrecorder is sg2):

crw-rw---- 1 root cdrom 21, 1 Mar 14 2002 sg2

If it doesn't say "cdrom" as group, change the group into "cdrom" (using the command chgrp explained earlier), make sure that owner and group have "rw" permissions on it (chmod 660) and make sure that your user is in the cdrom group.

Then try K3B again (you might need to log on and off for permissions to work).

Good luck.

Under wich kernel are you trying to burn as user?

Victory!
i did a "grep -i" on sg0 and changed "disk" to "cdrom" and gave "rw" permissions with chmod 660.
It did the trick
But then I had no sound on my cdrom player, so I ran alsaconf again to fix the problem.
A million thanks for your help!

I'm using Kernel 2.4.2

YES !!!!!!!!

I love to fix these problems. Good luck with the burner.
