# WHATPORT(5560)

## NAME

port 5560 — Oracle iSQL*Plus (unassigned at IANA) — An Oracle 10g database with the browser-based iSQL*Plus console still running.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists 5558-5564 as unassigned. The use that put 5560 on port lists is Oracle iSQL*Plus, the browser front-end to SQL*Plus, which Oracle 10g served from an OC4J instance at http://host:5560/isqlplus/; the actual port for an installation is recorded in $ORACLE_HOME/install/portlist.ini. Oracle dropped iSQL*Plus after 10g, so a live 5560 means an old database server. Legacy RSA ACE/Server services files also placed sdlockmgr, its lock manager, on this port.

## EXPOSURE

**Do not expose.** iSQL*Plus is a web login straight into a database over plain HTTP — exposing it publishes both the credentials and the SQL console.

## CHECK

```sh
curl -sS -o /dev/null -w '%{http_code}\n' http://TARGET:5560/isqlplus/
```
