# WHATPORT(1078)

## NAME

port 1078 — Avocent Proxy Protocol — An Avocent/Vertiv KVM proxy — remote console sessions to serial, KVM, and service-processor targets tunnel through here.

Protocol: TCP  
IANA registry

## DESCRIPTION

Avocent (now Vertiv) registered 1078 for its proxy protocol, and DSView management software uses it to tunnel KVM video, serial, and service-processor sessions between clients and appliances so that clients never need a direct route to the managed hardware. Finding it open means a DSView server or an Avocent appliance is on the network, sitting in front of the out-of-band consoles of everything it manages. The port is configurable but is left at 1078 in most installs.

## EXPOSURE

**Do not expose.** This is the front door to out-of-band console access for a whole rack estate. Keep it on the management network and reach it over a VPN, not from the internet.

## CHECK

```sh
nc -vz -w 3 TARGET 1078
```
