# WHATPORT(7744)

## NAME

port 7744 — RAQMON PDU — The registered TCP port for RAQMON reports — real-time application QoS measurements shipped from endpoints to a collector.

Protocol: TCP  
IANA registry

## DESCRIPTION

RFC 4712 defines RAQMON, an extension of the RMON family in which RAQMON Data Sources (endpoints such as IP phones or streaming clients) send session-quality reports to a RAQMON Report Collector. The RFC states that "port number 7744 is registered with IANA for use as the default port for RAQMON PDUs over TCP", and recommends TCP over the alternative SNMP-notification transport because TCP brings congestion control. Deployment is thin: Nmap sees the port open on about 0.015% of hosts, so most sightings are something else on a convenient number.

## EXPOSURE

**Expose with care.** RAQMON reports carry endpoint identities and session metadata; RFC 4712 leaves confidentiality to TLS or IPsec, so an unwrapped collector on a public IP leaks telemetry and accepts forged reports.

## CHECK

```sh
nc -vz TARGET 7744
```
