I want to make my own file server out of an old box i have sitting around.  I would like to use FreeNAS but i don't know if i can install and run sshfs like i can on my linux boxes.  I tried googleing around trying to find the answer but i can't find anything that tells me one way or the other.  Am I able to install sshfs on FreeNAS, or is there another way i can remotely mount a drive on my server and have the communication encrypted other than openvpn?  Any help or suggestions are greatly appreciated.  Thanks.
