# WHATPORT(1097)

## NAME

port 1097 — Sun Cluster Manager — IANA-registered to Sun Cluster Manager; almost never seen on a modern scan.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists 1097 as sunclustermgr, registered for Sun Cluster Manager, the management interface that shipped with Sun's clustering products for Solaris. Nmap's service-frequency data puts it near the bottom of the range, so an open 1097 today is far more likely to be an unrelated application that picked a free port above 1024. If you find it listening, identify the process locally rather than assuming the registration is accurate.

## EXPOSURE

**Do not expose.** The registration is a cluster administration plane; whatever is actually listening, an unidentified service on a management-range port does not belong on a public IP.

## CHECK

```sh
sudo lsof -nP -iTCP:1097 -sTCP:LISTEN
```
