Technical Details

what runs on :3883

VRPN is a network protocol and software framework for sharing virtual-reality peripheral devices between servers and clients. The registered port is 3883 over TCP and UDP; TCP is commonly used for client-server connections, with UDP available for supported traffic. Connections exchange protocol and device information, then carry framed messages containing device updates such as tracker poses, button states, and analog values. VRPN is not a general-purpose peripheral discovery service, and deployments typically configure the devices a server exposes.

tcp · udp

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

security overview

VRPN traffic is not encrypted by default, so device data can be observed on an untrusted network. Keep servers on a trusted or segmented network and restrict access with firewall rules; internet exposure is unusual and generally unnecessary.
