4 Access Your Oracle Big Data Cloud Service
This section describes how to access clusters and the tools, utilities and interfaces available in a cluster.
Note:
By default, the port used for accessing the cluster through SSH, port 22, is open and other ports used for accessing other services are closed. You can control access to the ports by configuring the network whitelist (for clusters hosted in regions) or by configuring the firewall (for cluster hosted in availability domains). The configuration controls whether network requests from specified IP addresses (or ranges of addresses) will be accepted or denied at specified ports. See Control Network Access to Services.
