An update for anyone who is still reading out there...

Everything is working but I'm running into permission errors with Unison. So far the Unison read-mes/FAQs hasn't been able to help...

The error looks like this:

Failed [<filename>.<extension>]: Error in processing transfer instruction:
Permission denied [open(/home/<username>/syncpath/.#<filename>.<extension>.fad34f31b165a59adb3d7fd2e3c03217.unison.tmp)]
(This is a path on my Ubuntu "server")

I've Googled that particular error and didn't get many hits so now I may have to resort to reading some threads in the Unison user groups.

Greetings!

There are more alternate ways you can test out. iFolder project is coming out of beta nowadays. Should worth a try for your problems. Other side some OpenVPN and dynamic-dns or dns update for your own can be applied instead of a third party vpn.
(Anyhow - I still trying to make openVPN server to work on windows machines but it looks hard. iFolder needs to be tested but looks promising.)

Anyhow my problem is a bit different, i want a *nix-like box to sync to another one (handle deletes and new files too.) But still no well idea. (the other *nix box must be handled like an untrusted one.)

Good luck for your solution! Looking ahead to read about your progress!

Tim, did you check permissions for that file?

/home/<username>/syncpath/.#<filename>.<extension>.fad34f31b165a59adb3d7fd2e3c03217.unison.tmp

Anyway, Unison should not sync its own temp files.

You could try to ignore it:

ignore = *.unison.tmp
