# WHATPORT(1086)

## NAME

port 1086 — CPL Scrambler Logging — Registered as CPL Scrambler Logging; the product behind the name is not publicly documented.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists 1086, 1087, and 1088 as a set — cplscrambler-lg (logging), cplscrambler-in (internal), and cplscrambler-al (alarm log) — registered to Richard Corn. No specification, manual, or implementation for "CPL Scrambler" is publicly available, so the registry entry is all that can be verified. Traffic you see on 1086 in practice is usually an ephemeral client socket or an unrelated application, not this service.

## EXPOSURE

**Expose with care.** Nothing is documented about the protocol, so identify what is really listening before allowing it through a firewall.

## CHECK

```sh
nmap -sV -Pn -p 1086 TARGET
```
