[SOLVED] mount option nodev

[blueiced]

Dear all linuxers,
does someone know what the function from "nodev" mount option is?
i'm in a middle of study for OS Hardening, and one of them is Red Hat..
From what i get until now, nodev means don't set a character / special devices access in a partition.
I don't really understand it, maybe someone can give real example how do this option behave within the system? and what is the side effect turning this option in a filesystem?
Thanks..

The 'nodev' option means that there is no device associated with this file system. Examples of this would be nfs or cifs (network) file systems, etc. Do read the man page for the 'mount' command for more information.

thank you for your reply, Rubberman..

The man pages aren't always that informative. The 'nodev' option *is* used for remote file-systems, but it's also used as a security measure by preventing device-files (a special type of file representing a hardware device) from be interpreted as such (if found on that mounted file-system). Obviously, it makes sense for a remote file-system, since that host isn't attached to the same hardware devices anyway.
