Private syncing between multiple servers

[illDecree]

For a long time i've been manually creating torrents, encrypting them, and sending them out to two specific people to share files (legal of course)

now, i want to change that: i want to find a way to set up a dedicated box where i am, and two more at the other two locations. i need them to 'sync' with each other. ie: i drop a file on the share, and the other two boxes pick up and sync that file, same on all three ends.

think Dropbox minus the cloud storage.

Requirements:

MUST run on Windows (WinXP Pro x86) (support reasons, as the three boxes are in three states)

MUST encrypt the connection

Must be able to run on a headless server.

what's the best solution for this?

I would do it with rsync, which normally is done over a ssh connection.. Easier to setup ssh server on linux, your headless box could be linux I would assume.

There are lots of ssh clients for windows, not so many servers setups.

Then grab the windows binary for rsync http://www.itefix.no/i2/node/10650 for your two client machines, and a ssh client - putty would work just fine.

Or for that matter you could just setup a network with hamachi for all three of your machines, then use rsync directly since your connection would all be secure over the hamachi vpn.

There are lots of sync tools out there - I would think any of them would work, just connect your 3 machines together securely with hamachi

OpenSSH provide a Windows SSHd which will work fine, then as BudMan said - rsync :)

If you find that setup a bit daunting you could configure a TLS/SSL FTP?

Well not so much that they do. But sure there are windows binaries of it, well actually they run with cygwin, etc.. Same place to get windows rsysnc has ssh version for windows

Windows Live Mesh allows you to do this and skip the cloud.
