If you're anything like me, you have a copy of your annex on a computer running at home¹, set up so you can access it from anywhere like this:
- ssh myhome.no-ip.org
+ ssh myhome.no-ip.org
This is totally great! Except, there is no way for your home computer to pull your changes, because there is no onthego.no-ip.org. You can get clunky and use a bare git repository and git push, but there is a better way.
First, install openssh-server on your on-the-go computer
- sudo apt-get install openssh-server
+ sudo apt-get install openssh-server
Then, log into your home computer, with *port forwarding*:
- ssh me@myhome.no-ip.org L 2201:localhost:22
+ ssh me@myhome.no-ip.org L 2201:localhost:22
Your home computer can now ssh into your on-the-go computer, as long as you keep the above shell running. Presto, you can use the same shell to set up your remote:
- ssh-keygen -t rsa
- ssh-copy-id localhost -p 2201
- cd ~/annex
- git annex remote add on-the-go ssh://localhost:2201/home/myuser/annex
+ ssh-keygen -t rsa
+ ssh-copy-id localhost -p 2201
+ cd ~/annex
+ git annex remote add on-the-go ssh://localhost:2201/home/myuser/annex
And run normal annex operations:
- git annex sync
- git annex get on-the-go some/big/file
- git annex status
+ git annex sync
+ git annex get on-the-go some/big/file
+ git annex status
You can add more computers by repeating with a different port, e.g. 2202 or 2203 (or any other).
If you're security paranoid (like me), read on. If you're not, that's it! Thanks for reading!

* Any dropbox employee can conveiably use your installed dropbox to look at any file on your computer
* A truly huge amount of eyes connected to incredibly smart brains have looked at openssh and found it secure. Everybody trusts openssh. With dropbox, there is, well, dropbox. Whoever that is.
