Title: Altered net permissions to disable netstat information leak

Changing these file permissions in /proc/ makes it impossible for users to read this information and thus utilities like netstat will fail to leak information about other gears.

There's not much that can be done with this information that you can't get from a portscan, that said, still best to disable it.
