Comments 4 Posted In Red Hat Enterprise Linux Disable cdrom/dvd RHEL 6.2 for non-root users Latest response 2019-10-09T15:17:12+00:00 What is the best practice to disable the cdrom/dvd for non-root users? I was able to move/rename the cdrom.ko file in RHEL 5, but RHEL 6 this does not work! re Started 2013-06-20T17:12:09+00:00 by redhat_css_young Community Member 65 points Log in to join the conversation Responses Sort By Oldest Sort By Newest rh Red Hat Active Contributor 387 points 21 June 2013 8:37 AM rhn-support-mkpai Please try echo "blacklist sr_mod" >> /etc/modprobe.d/blacklist-sr_mod.confAfter reboot, the sr_mod driver will not initialize. The root user can circumvent this by /sbin/modprobe sr_modPlease let us know if this works for you.

I also tried adding blacklist sr_mod /bin/true and that didn't help. Has anyone been successful in blocking this .ko ?
