sudo usage- basic question

groxy · 12-05-2007, 10:19 AM

Hi
I have the following entries in /etc/sudoers

root ALL=(ALL) ALL
oracle All = /sbin/dd, /bin/mount, /sbin/mount.cifs, /bin/umount

However, I still need to input root's password when i want to execute "umount" command as oracle user.
I tried
> umount "some_directory"
> sudo umount "some_directory"
> suod /bin/umount "some_directory"
None o this work

What am I doing wrong?

Thanks for any advice

Are you putting in roots password or oracles password? Sudo shouldn't be asking you for roots password. Ever.

I don't know if it makes a difference, but you may have to capitilize the word ALL. So it should be:

oracle ALL = /sbin/dd, /bin/mount, /sbin/mount.cifs, /bin/umount

And if you don't want to have to supply oracle's password, you need to add the NOPASSWD directive:

oracle ALL = NOPASSWD: /sbin/dd, /bin/mount, /sbin/mount.cifs, /bin/umoun

Something isn't right here. As I said, if you're asked for a password, it would be your own (in this case oracle's) not roots. Have you tried entering oracle's password?

The whole basis for sudo is that the system administrator uses it to give certain users the ability to run specific commands as root, without knowing root's password. However, as a safety precaution, sudo asks the user for their password, just in case it isn't actually that user entering the command.
