Unix-like Syslog uses which port by default?

Explanation:
Syslog on Unix-like systems traditionally uses UDP port 514. This comes from the original design of the syslog protocol, where log messages were sent as simple datagrams to a syslog server on port 514. UDP keeps the overhead low and works well for log streaming where occasional packet loss is acceptable. While you can configure systems to use TCP or TLS for reliability and encryption (for example, port 6514 is commonly used for Syslog over TLS), the out-of-the-box, default behavior is UDP 514. So, when you think of the default setup, UDP on port 514 is the standard choice.
