Technical Details

what runs on :6419

VDR listens for discovery traffic on UDP port 6419 so clients can locate recorder instances, typically on the local network. This is discovery traffic, not an ongoing SVDRP command session; the command interface normally uses TCP port 6419. The UDP discovery exchange is not encrypted.

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

An exposed UDP listener may disclose that a VDR instance is present, but this discovery endpoint is not the recorder's command channel. It is intended for local-network discovery and generally should not be exposed to the public internet; restrict it at the network boundary.
