Hello:

This is probably a redudnant post, I'm sure, but I can't find the answer to my question.

I can mount and use cdrecord from root but not from another user

This is from root:

[root@plutonium root]# cdrecord -scanbus
Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 Jörg Schilling
Linux sg driver version: 3.1.25
Using libscg version 'schily-0.5'

1,7,0 107) *
[root@plutonium root]#

This is from the user:

[mpdegroat@plutonium ~]$ cdrecord -scanbus
Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 Jörg Schilling
cdrecord: Permission denied. Cannot open '/dev/sg0'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
[mpdegroat@plutonium ~]$

Here's what my fstab looks like:[mpdegroat@plutonium ~]$ more /etc/fstab
/dev/hda2 / ext3 defaults 1 1
/dev/hda1 /boot ext3 defaults 1 2

Any suggestions or help will GREATLY be appreciated.

It's normal, you've to be root to install/remove programs and change any configuration file outside your /home/user directory, among other things. You not really have logout and login again to be root. At the terminal, type "su". You will be prompted for the root password. Now you are root. When done, type exit to come back to non-root user .

Give the user an rw access to the /dev/sg0; either by adding the user to the same group as where the /dev/sg0 is, or Giving rw access to all the users for the device.

BINGO! Changed permissions to rw on /dev/sg* on it works now.

Thanks,

Michael
