You should start this tutorial at a prompt that looks something like this:
root@ip-10-82-233-6:~#
Type ‘cd’ to go to your home directory on your EC2 machine.
%% cd
Now, download the dropbox file:
%% wget -O dropbox.tar.gz "http://www.dropbox.com/download/?plat=lnx.x86_64"
Extract the file:
%% tar -xvzf dropbox.tar.gz
Run dropboxd:
%% ~/.dropbox-dist/dropboxd &
..and you should see a message like this:
This client is not linked to any account... Please visit https://www.dropbox.com/cli_link?host_id=XXXXX to link this machine.
Copy/paste that URL into your Web browser; log into dropbox; and voila! The directory ~/Dropbox will be linked into your home directory!
