<h2 class="title">Domain Socket Support</h2>
<p class="para">
MongoDB has built-in support for via Unix Domain Sockets and will open the
socket on startup, by default located in <var class="filename">/tmp/mongodb-<port>.sock.</var>.
</p>
<p class="para">
To connect to the socket file, specify the path in your MongoDB connection
string:

<p class="para">
If you would like to authenticate against a database (as described above)
with a socket file, you must specify a port of <em>0</em> so that
the connection string parser can detect the end of the socket path.
Alternatively, you can use the constructor options.
