          <h2>Connecting from a Linux Host</h2>

<ol>
	<li>Log into the source Linux host</li>
	<li>Run the following command in a terminal window
	<div class="codeBlock"># generate a new ssh key pair<br />
	ssh-keygen -t rsa</div>
	</li>
	<li>Press enter to accept the default location</li>
	<li>Optionally, set a password for the key pair<br />
	<em>NOTE: If you don&#39;t provide a password, anyone with the key and access to the target host can connect using the key. Proceed with caution</em></li>
	<li>Continue with the following command
	<div class="codeBlock"># output the public key<br />
	cat ~/.ssh/id_rsa.pub</div>
	</li>
	<li>Copy the output ssh-rsa public key to the clipboard</li>
	<li>Log into the target Linux machine</li>
	<li>Run the following command in a terminal window
	<div class="codeBlock"># create .ssh directory<br />
	mkdir ~/.ssh -p<br />
	# edit the authorized_keys file<br />
	nano ~/.ssh/authorized_keys</div>
	</li>
	<li>Paste the copied public key to the bottom of the file</li>
	<li>Press CTRL+O, Enter, CTRL+X to write the changes</li>
	<li>Back on the source Linux device, connect to the Linux target using ssh (ie ssh username@hostname)</li>
	<li>Type yes and press Enter the first time connecting with a new public key to accept the connection</li>
