This won’t mean much or even be useful to people who don’t use a unix type operating system. Which means it should work fine for most everyone but Windows users. 🙂
SSH stands for Secure Shell, and is actually a protocol for connecting to a remote machine in a secure manner. You can transfer files over it, and interact as if you were working directly on the remote machine.
SSHFS allows you to mount a remote filesystem over ssh. Then your computer thinks it’s a normal directory full of stuff, but it’s actually the material on the remote server.
I got it working today with relatively minimal trouble, and it’s quite cool. Much faster than I expected.
