# WHATPORT(2006)

## NAME

port 2006 — invokator — Registered as invokator with no description; nothing well known runs here.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers 2006/tcp as invokator and 2006/udp as raid-cd, both undocumented holdovers from the early registry. There is no public specification and no widely deployed software that claims the port. The plausible cause of an open 2006 is Cisco reverse telnet to line 6, or an application that took a free port in the 2000s range.

## EXPOSURE

**Expose with care.** Unidentified listener: fingerprint it and do not publish it until you know what it is.

## CHECK

```sh
nc -vz TARGET 2006
```
