Both of these protocols are involved in the process of transmission of data. While UDP is used in situations where the volume of data is large and security of data is not of much significance, TCP is used in those situations where security of data is one of the main issues. While the transfer of data, the existence of ports is a matter of high significance. Each data packet comes with a port number associated with it. This enables the protocols to decide that what are the requirements of the data packets and to which port are they supposed to be directed. In fact, the existence of ports is crucial to make sure that data packets reach their desired destinations accurately.

This document applies to all versions of Horizon 7 from 7. Figure 1 shows three different client connection types and also includes all display protocols. Different subsets of this diagram are displayed throughout this document. The embedded diagrams and those in the pdf are screen resolution versions. If higher resolution and the ability to zoom is required, for example to print as a poster, click on the desired diagram using the online HTML5 version of this document. This will open a high-resolution version which can be saved, opened in an image viewer, and printed. This document also contains tables that list all possible ports from a source component to destination components.

List of TCP and UDP port numbers

Port numbers 0 to are reserved for privileged services and designated as well-known ports. This list of port numbers are specified in RFC The port number identifies what type of port it is. For example, port 80 is used for HTTP traffic. Port numbers range from 0 to , but only port numbers 0 to are reserved for privileged services and designated as well-known ports.

Datagram in UDP is similar to the packet of information. All the back-and-forth communication and deliverability guarantees slow things down. UDP is said to be an unreliable transport protocol but it uses IP services which provides best effort delivery mechanism. This allows data to be transferred very quickly, but it can also cause This protocol is not reliable and connectionless which is why its in use where it is not necessary to establish a connection between application before the data transfer. It provides an unreliable datagram connection between applications.

Below, we take a look at these protocols, provides a basic description of their function, and lists the port numbers that they are commonly associated with. FTP is one of the most commonly used file transfer protocols on the Internet and within private networks. An FTP server can easily be set up with little networking knowledge and provides the ability to easily relocate files from one system to another. SSH is the primary method used to manage network devices securely at the command level. It is typically used as a secure alternative to Telnet which does not support secure connections. Telnet is the primary method used to manage network devices at the command level. Unlike SSH which provides a secure connection, Telnet does not, it simply provides a basic unsecured connection.

What are the TCP/IP Well Known Port Numbers (0 to 1023)

This is a list of Internet socket port numbers used by protocols of the Transport Layer of the Internet Protocol Suite for the establishment of host-to-host communications. Contents 1 Table legend 2 Well-known ports 3 Registered ports 4 Dynamic, private or ephemeral ports 5 See also 6 References 7 External links. Well-known ports The port numbers in the range from 0 to are the well-known ports. They are used by system processes that provide widely used types of network services.

Similarly many of the official assignments refer to protocols that were never or are no longer in common use. This article lists port numbers and their associated protocols that have experienced significant uptake. 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 well-known ports.

How to Find Out List of All Open Ports in Linux

In this article, we will briefly talk about ports in computer networking and move to how you can list all open ports in Linux. In computer networking, and more definitely in software terms, a port is a logical entity which acts as a endpoint of communication to identify a given application or process on an Linux operating system. It is a bit number 0 to which differentiates one application from another on end systems.

For example, port 80 is used by web servers.
