This is a filesystem client based on the SSH File Transfer Protocol. Since most SSH servers already support this protocol it is very easy to set up: i.e. on the server side there's nothing to do. On the client side mounting the filesystem is as easy as logging into the server with ssh. Note, that it's recommended to run it as user, not as root. For this to work the mountpoint must be owned by the user. If the username is different on the host you are connecting to, then use the "username@host:" form. If you need to enter a password sshfs will ask for it (actually it just runs ssh which ask for the password if needed). You can also specify a directory after the ":". The default is the home directory.
