I know this is hardly the most appropriate forum but it's the only computer one I'm registered in and I don't frequent apple forums so my question is:

I would like to disable the ability to use the tenet command on the Mac OS X 10.8 terminal.

What do I have to do, what specific file do I have to delete ?? it's in system ? library->??

Also on mountain lion why is there no option to turn IPv6 off?? it only shows me link-local or wtf
