If it is a Gnome setting, one could set the mandatory settings and then the non-root user would not be able to change various Gnome setting. This is describe in the Gnome administrator's guide. http://library.gnome.org/admin/system-admin-guide/stable/ This maybe adequate. As for KDE? I don't know. For the cdrom, you could also look into the /etc/fstab file, which provides various options in how the device is mounted (man fstab). This is more restrictive and may provide the best solution to the cdrom. As for USB devices, I haven't found a good answer yet, since USB is also driving the mice and keyboards now days. ~smbinyon -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Kurian Thayil Sent: Saturday, December 13, 2008 12:34 AM To: General Red Hat Linux discussion list Subject: Re: Mount Hi, In Gnome, Desktop --> Preferences --> Removable Drives and Media. Make the necessary configuration there for each user. This will not block the user as the user has the privilage to change the setting back to previous. Or you have the option to change the HAL settings. If haldaemon is stopped, no new drives will be automatically detected and mounted. You will have to mount it manually in GUI. There could be better suggestions/answers. I don't know much about KDE. Regards, Kurian Mathew Thayil.
