Does syslog use UDP?

Is syslog-ng Open Source?

What is difference between syslog and syslog-ng?
They’re all syslog daemons, where rsyslog and syslog-ng are faster and more feature-rich replacements for the (mostly unmaintained) traditional syslogd. syslog-ng started from scratch (with a different config format) while rsyslog was originally a fork of syslogd, supporting and extending its syntax.
Is syslog a transport protocol?
3.2 Syslog Transport Protocols. By default, syslog uses user datagram protocol (UDP) to transport messages from “client” to “server”. However, there might be specific design requirements that required you to consider other options for transporting messages across the LAN or WAN networks.
What are UDP settings?
User Datagram Protocol (UDP) is a communications protocol that is primarily used to establish low-latency and loss-tolerating connections between applications on the internet.
