A database service is listening on the remote host.
The remote host is running Oracle, a database server.
It may be possible to extract the version number of the remote TNS
(Transparent Network Substrate) listener by sending a 'VERSION'
request to the TNS listener service operating on this port.
Note that the version of the TNS listener does not necessarily reflect
the version of the Oracle database it provides access to.
Restrict access to the database to allowed IPs only.
