Of course both sudo and su give the same Permission denied. I just discovered the same problem with Fedora5 too, but not Fedora4 and Fedora7. What going on???

Is the cdrom automonted? Try to umount and mount manually, maybe it's a problem with automount or fstab options.

mount shows:

automount(pid1691) on /net type autofs (rw,fd=4,pgrp=1691,minproto=2,maxproto=4)
/dev/hdc on /media/A1TEST2 type iso9660 (ro,noexec,nosuid,nodev,uid=500)

so I fed it:

mount -o remount,ro,nosuid,nosuid,nodev,uid=500 /media/A1TEST2

and it still gives Permission denied. Am I missing something?

[quote name="Alexandre Chabert"]type mount in a shell and look at the options there are for the cdrom. There should be a 'noexec' one ( it means no executable so impossible to launch a program from it ).

If there is, copy all the options minus noexec and type as root or sudo in a shell ( change the path and the options with wath you have ):

mount -o remount,option1,option2,optionN /path/to/cd[/quote]

ok now try mounting the cdrom like this:

mount -o remount,defaults,exec /media/A1TEST2

Check with mount that the options are ok and test. If this doesn't work mount the CD in a distribution that works and try with the options you see.

If this still doesn't work I'd say it smells like selinux so as a last resort put it in permissive mode or disable it and try again.

Thanks, that works! I tried setting SELinux to permissive and just disabling it. Don't know what else it could be other than demon-possesion. >:-]
