Can Tail OS tunnel all other softwares not including in the original Tail Linux through Tor? If not, which can?"bufumg"
Tails is designed to force all connections through Tor, if that's what you're asking. Some things however won't work. For instance the FTP protocol doesn't work with Tor. But at least in theory, anything you install on Tails will either connect through Tor, or at worst fail to connect at all. Of course there's a separate issue that Tails is amnesiac, so anything you want to use repeatedly will have to be reinstalled every time you restart the OS.
