Internet TCP port 543 is commonly used by the Kerberos network authentication protocol. This protocol is used to provide strong authentication for client/server applications by using secret-key cryptography. Examples of systems that use this protocol include Microsoft Windows 2000 and later versions, as well as Unix-based systems.

Port 543, used by both TCP and UDP protocols, plays a significant role in providing secure and authenticated remote login capabilities through the Kerberized rlogin service. By leveraging Kerberos authentication, the klogin service offers an enhanced level of security compared to the standard rlogin service.

In PostgreSQL's case it's typical to use port 5432 if it is available. If it isn't, most installers will choose the next free port, usually 5433. You can see what is actually running using the netstat tool (available on OS X, Windows, and Linux, with command line syntax varying across all three).

2025年1月7日 · What is Port 543? Port number 543 is primarily associated with the "klogin" service, which provides a remote login capability for users on Unix-based systems. This protocol allows users to securely log in to remote machines using their existing credentials, facilitating remote system administration and management.

0番のポートはエニーポート（any port）と呼ばれ、アプリケーションに対して、動的に別番号の空きポートを割り当てるために用意された特殊なポート番号である。

This page will attempt to provide you with as much port information as possible on TCP Port 543. TCP Port 543 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network.

2025年3月11日 · Service names and port numbers are used to distinguish between different services that run over transport protocols such as TCP, UDP, DCCP, and SCTP. Service names are assigned on a first-come, first-served process, as documented in [ RFC6335 ].
