# WHATPORT(7778)

## NAME

port 7778 — interwise — Registered to Interwise, but in the field it is mostly "the port next to 7777".

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA assigns 7778 to interwise, a corporate e-learning and conferencing product, with no public protocol specification. What actually shows up on scans is the sequential neighbour effect: a host already using 7777 for a game or application server takes 7778 for a second instance, a query port, or an admin channel. The registration is not a reliable identification, so read the banner and the owning process rather than the name.

## EXPOSURE

**Expose with care.** Identify it before opening it — when 7778 is the companion of a 7777 service it is frequently the query or admin side, which is the half you least want reachable.

## CHECK

```sh
nmap -Pn -sV -p 7777-7778 TARGET
```
