Technical Details

what runs on :1935

The normal protocol is Real-Time Messaging Protocol (RTMP) over TCP port 1935. RTMP begins with a versioned handshake and then exchanges timestamped, chunked messages carrying commands, media, and application data, commonly encoded with AMF. HTTP-tunneled RTMP and TLS-protected variants historically used ports 80 and 443; UDP registration is associated with Flash media-server protocol support but is not the usual transport for classic RTMP.

Security Information

2/ 10safe

routine exposure. this port is rarely the way in on its own — keep it patched and logged and move on.

streaming averages 3.1 across 45 ports — this one sits 1.1 below.

assignment

official

registered with iana for this service — scanners fingerprint it by number

reachable over

tcp · udp

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

security overview

Classic RTMP is not encrypted by default, so media and application traffic can be observed or manipulated in transit. Legacy deployments should not be exposed directly to the internet without authentication, patching, and strict application controls; however, this assignment appears obsolete and was never observed open in the cited scan data.
