SSH Kung Fu 
A trick I learned recently: create .ssh/config<p>File format: as many of the following blocks as you like<p><pre><code>  Host $ALIAS <-- whatever you want here
  Hostname www.example.com
  User someuser
  Port 1234
</code></pre>
You can now ssh to that server as that user by doing "ssh $ALIAS" on the command line, without needing to specify the port or user with the usual command line arguments, or necessarily spell out the entire host name.
