<title>Commonly-used network ports</title>
<p>This is a list of network ports commonly used by applications that provide
network services, like file sharing or remote desktop viewing. You can change
your system’s firewall to <link xref="net-firewall-on-off">block or allow
access</link> to these applications. There are thousands of ports in use, so
this table isn’t complete.</p>
