  <title>常用网络端口</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>
