Editing Amazon AWS/EC2

== Accessing Instance ==

You must change permissions of the key pair to 400.

<pre>chmod 400 /path/my-key-pair.pem
ssh -i /path/my-key-pair.pem ubuntu@ec2-198-51-100-1.compute-1.amazonaws.com</pre>

Another handy thing to do is single-sign on. Now that you've authenticated once with your SSH private key, you might as well have it authenticate the password anyway, so you don't have to type it in yet again for sudo.

== How to Use Byobu ==

Your shell is equipped with Byobu, which is a nifty shell that allows processes to stay running even if you disconnect. It also allows you to have multiple tabs, a must have when running multiple processes.

* <code>F2</code> (New Tab) - Press this button to create a new tab.
* <code>F3</code> (Switch Tab) - Press this button to toggle between tabs.
* <code>F6</code> (Disconnect) - Press this button to disconnect from the shell. Your programs will still keep running and you can check back on them next time you log in.
* <code>exit</code> - Run the <code>exit</code> command in any tab to close that tab when you no longer need it.

If you are using PuTTY and are facing issues with the function keys, [http://codeyarns.com/2013/01/21/byobu-function-keys-do-not-work-in-putty/ set this up.]

* The Internet Archive requires metadata for creating new objects. For now, just create new objects using the web interface and upload a small file.
* Then, upload the real files from the server using:
* <code>ia upload &lt;identifier&gt; file1 file2</code>
