Best Secure Protocol For Accessing Fileserver over WAN?
I am setting up a home fileserver and would like to be able to mount the filesystem on my laptops running Ubuntu and Mac OS X. I want to be able to mount the filesystem over both the LAN and Internet and so I want the protocol to be secure. I am debating between NFSv4, OpenAFS, and WebDAV. Do you have any recommendations about which filesystem would be best? It seems that OpenAFS is quite secure but creates a meta-filesystem that could make it hard to get my data out in case of a problem.
Or would it be best to set up a VPN for accessing my files securely?
