The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...

In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service.
The build-from-source option also allows the ports system to automate installation of software with a license that does not permit redistribution. The ports collection contains over 31,000 ports, of which over 2,200 are in scientific categories, and over 240 are biology-related. New ports and updates are listed on the Fresh Ports [2] site. pkgsrc
