We're running Ubuntu 10.04 in one office and we want a couple of Mac's in another office to be able to connect to shares on this computer. We want a fairly simple solution to this if one exists. We started looking at setting up a VPN using PPTP but it seems quite complicated. I've also seen mention of VNC, but this seems more related to sharing desktops.
All I want to do is share a directory. Can I just install OpenSSH and have the Mac users mount a share over SSH using public/private key encryption?
