<p>s*(((([“‘]).*?<a href=”^/’“>”>5)|</a>*)*?)(/)?&gt;/um, true)</p>

<p>The available options are:</p>
<dl class="rdoc-list note-list"><dt>port
<dd>
<p>Port number (default value is 21)</p>
</dd><dt>ssl
<dd>
<p>If <a href=":ssl">options</a> is true, then an attempt will be made to use
SSL (now TLS) to connect to the server.  For this to work <a
href="FTP/OpenSSL.html">OpenSSL</a> [OSSL] and the Ruby <a
href="FTP/OpenSSL.html">OpenSSL</a> [RSSL] extensions need to be installed.
If <a href=":ssl">options</a> is a hash, it’s passed to
OpenSSL::SSL::SSLContext#set_params as parameters.</p>
</dd><dt>private_data_connection
<dd>
<p>If true, TLS is used for data connections. Default: <code>true</code> when
<a href=":ssl">options</a> is true.</p>
</dd><dt>username
<dd>
<p>Username for login.  If <a href=":username">options</a> is the string
“anonymous” and the <a href=":password">options</a> is <code>nil</code>,
“anonymous@” is used as a password.</p>
</dd><dt>password
<dd>
<p>Password for login.</p>

All of these hrefs are wrong. I'm not exactly sure what they're supposed to be.

Start by inspecting the two generated documentation pages linked in the report and compare each broken href with the surrounding RDoc markup shown in the issue. The intended replacement targets are not specified, so confirm the correct destinations before changing anything, then verify that all reported links resolve correctly.
