Checking Services/Ports

Checking Services/Ports

The FusionStorage system provides a variety of services and ports to facilitate your operations. However, unnecessary services and ports may reduce system security and must be disabled as soon as possible.

It is recommended that the administrator periodically check for and stop unnecessary services and ports to prevent security risks. For details about the services and ports provided by the system, see Communication Port Matrix.

To check services/ports, do the following:

  1. Locally log in to the node as root.
  2. Check services and ports.
    • Run netstat -an |grep LISTEN |grep tcp to check TCP services and ports.
    • Run netstat -an |grep udp to check UDP services and ports.
