sshfs is a filesystem client based on ssh. It allows you to mount remote system folders and access them similar to any storage device. Sooooo coool!!!
Here is the one-liner I use when invoking sshfs:
sshfs -o allow_other -o default_permissions -o IdentityFile=~/.ssh/id_rsa username@ipaddress:/path /local/path
-o allow_other= allow access to other users on your system.
-o default_permissions= enable permission checking. (By default, file permissions are ignored by SSHFS. This option makes it pay attention.)
IdentityFile=~/.ssh/id_rsa= set the path to your private key file
