Technical Details

what runs on :1605

The Salutation Protocol is an application-layer service-discovery protocol used by Salutation Managers. It supports both TCP and UDP on port 1605, with managers exchanging protocol messages to locate services and describe their capabilities; traffic is not HTTP-based and does not use encryption by default. This assignment should not be confused with the more widely known Service Location Protocol, which uses port 427.

Security Information

tcp · udp

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

security overview

Salutation traffic is normally cleartext, so service and capability information can be observed or modified in transit. Exposing it to the public Internet is unnecessary; restrict it to trusted local networks and review legacy implementations for parsing, spoofing, and denial-of-service risks.
