<p>The following provides a summary of your relay's inbound and outbound
connections. Couple important notes...</p>
<blockquote>
<div><ul>
<li><p class="first">To use this you must set <strong>DisableDebuggerAttachment 0</strong> in your torrc.
Otherwise connection information will be unavailable.</p>
</li>
<li><p class="first"><strong>Be careful about the data you look at.</strong> Inspection of client and exit
traffic especially is wiretapping and not only unethical but likely
illegal.</p>
<p>That said, a general overview like this should be fine.</p>
