Trying to get two file servers set up between two locations - both on residential connections, so no static IPs. Want to have them synchronize back and forth. Had actually (gasp!) Considered Windows Server - as their DFS (Distributed File System) does exactly what I want. But, at $800/server, puts it out of the budget for this project. (Looked at new hardware costs and I'd spend 3/4 of that on each machine for a loaded little box!) Currently using spare hardware, with plans to upgrade when funds/needs allow/require. Thinking DynamicDNS (of some sort) for identifying the other machine, then poke a (single) hole for an SSH'd connection. (Alternative: upload a simple text file to a web-server with IP in it. Wouldn't be dependent upon DNS updates, but shot this idea down as one of them I'd like to have a functional DNS entry for) Considering rsync (over ssh) for the actual transfer, unless there's some other (easier/more capable) solution. (Concern: multi-user changes at both locations) Running Ubuntu 10.04 LTS currently on both machines. Looked at Unison, but it isn't being developed anymore, and don't want to start on a tool that is in discontinued status. Thoughts, improvements? Thanks! -Keith Bachman
