What happens on syslog-ng if no transport is configured, but UDP port is set?

Question

By default, as stated in the documentation of syslog-ng, the default Transport Protocol used by syslog-ng is TCP.,

If I don't configure the Transport Protocol, but instead I configure PORT 514 which is the default UDP port, what will happen? Will the communications go over TCP or UDP?

Answer 1

默认情况下，syslog-ng的syslog()和network()驱动程序使用TCP。将port()选项设置为514而不指定transport()意味着514 / tcp。
