title: connecting to multiple instances of EC2 with ssh
body: <p>I just started out with Amazon web services and was able to launch an instance. A friend showed me a sample tutorial of how to connect to AWS with ssh. Pretty neat. I downloaded the key and edited /.ssh/config file. 
  Sample of the config file</p>
  
  <pre><code>Host *
  ServerAliveInterval 300
  
  Host &lt;name desired to connect&gt;
   HostName &lt;domain name&gt;
   port 22
   User ubuntu
   IdentityFile /pathname/keyfile
  </code></pre>
  
  <p>My question is what if i have 2 instances and now i want to ssh to the new instance launched. How will i edit the config file. I'm stuck and also new to Linux(been learning Linux yesterday and it's pretty cool and powerful). Thanks for the help.</p>
