Local network (ssh) fails to pair/sync

Please describe the problem.

I am trying to set out two computers on the same network to synchronise.

What steps will reproduce the problem?

Install Git-Annex. Start the webapp. Try to connect. Enter a secret phrase on both. The Mythbuntu machine shows "Failed to sync with Inspiron 14z" (the laptop). The laptop shows "Pairing in progress" forever.

The machines can normally connect together passwordlessly through ssh with public key encryption.

What version of git-annex are you using? On what operating system?

Ubuntu Raring Version: 3.20121112ubuntu2 from the repos on my laptop. Install version 4.20130627 from the PPA on Mythbuntu Precise (which I use as a home server).

Please provide any additional information below.

From the the laptop, where I started the pairing:

# If you can, paste a complete transcript of the problem occurring here.
# If the problem is with the git-annex assistant, paste in .git/annex/daemon.log

Some things working

Oh, that's odd...

The Mythbuntu machine says it fails and the laptop screen still says pairing, but a new window on the laptop says that it synced with the Mythbuntu server. On the Mythbuntu server, it has a blank entry for the laptop, which if you click to edit says "Internal Server Error" "Unknown UUID".

When I add things on the laptop, they immediately become shortcuts and an equivalent shortcut appears on the Mythbuntu machine, though updates to the content (in this case a text file) are not sychronised.

Adding a file on the Mythbuntu machine does not turn into a shortcut and nothing appears on the laptop.

Remote mythbuntuserver.local_annex does not have git-annex installed; setting remote.mythbuntuserver.local_annex.annex-ignore

So, how did you install git-annex on mythbuntuserver? What does the .ssh/authorized_keys on mythbuntuserver look like? (In particular the key that git-annex adds to it, which should be set to run git-annex-shell.)
