how to mount a Rock Ridge iso9660 disc as a standard user?


Hello,

I am trying to mount an iso9660 CD on a Debian box. The disc seems to be protected by Rock Ridge file permission restrictions. This machine cannot be connected to any network to do transfer via another machine. The Rock Ridge permissions on the disc are root read/write/execute only (-rwx------). I do not have access to the root account on this system, so I do not have permission to read the files on the disc.

I see that there is a "mount" option called "norock" that should allow me to mount the CD as if the Rock Ridge controls didn't exist. However, if I try

$ mount -o norock /cdrom
mount: only root can do that

I need to get files off of the disc and onto the system. Is there any way that I can mount this cd as a standard user? Thanks for any suggestions.

Regards,
Mike

Why you don't copy down the files as root and change then the permissions ?

My guess as a non-expert is that the protection has nothing to do with the Rock Ridge system. Are you added to the CD-ROM group? If not, then your access to the CD-ROM device will be blocked in general. Are you able to read other CDs? If so, then possibly the files in question are given root permission only on purpose. Could you ask a sys admin to help you?

This shows that the disc was intended to only be read by the root user on a system it is placed in. I am not aware of any mechanism that would allow you to read these files without being root.

the system can read normal cds just fine. this disc in particular seems to have the Rock Ridge extensions. i guess i can copy the files and create a non-restricted cd on a machine that i have root access to.

thanks for the thoughts.

mike
