Not quite sure if this belongs in networking, linux, or what...


Opensource dropbox-type software?

Ive got a VPS and I want to use it for cloud storage. Is there any opensource software to sync folders to a server in this way?

Has to run on Linux.

I need it to work multi-way though. I.e. 2 desktops concurrently working, and the server mediating it all.
And to work on windows and Linux.
