Default Ports
The default ports used for communication with KAgent, Kinetica (and between servers, if operating in a cluster), and various important services follow. The Nodes column will list either Head--that the corresponding port only needs to be opened on the head node, or All--that the corresponding port needs to be opened on the head node & worker nodes.
Important
While the table below lists KAgent and the graph server as being on the head node, these features could be kept on machines entirely separate from Kinetica if desired.
| Port | Function | Nodes | Usage |
|---|---|---|---|
| 22 | This port is used by KAgent to manage cluster servers. For clusters not managed by KAgent, this will be needed to manage servers directly. | All | Required Internally |
| 2003 | This port must be open to collect the runtime system statistics. | All | Required Internally |
| 2004 | This port must be open to collect the runtime system statistics. | All | Required Internally |
| 4000+N | For installations which have the external text search server enabled and communicating over TCP (rankN.text_index_address = tcp://…), there will be one instance of the text search server listening for each rank on every server in the cluster. Each of these daemons will be listening on a port starting at 4000 on each server and incrementing by one for each additional rank. | All | Optional Internally |

| 9191+N | The primary port(s) used for public and internal Kinetica communications. There is one port for each rank running on each server, starting on each server at port 9191 and incrementing by one for each additional rank. These should be exposed for any system using the Kinetica APIs without authorization and must be exposed between all servers in the cluster. For installations where users should be authenticated, these ports should NOT be exposed publicly, but still should be exposed between servers within the cluster. | All | Required Internally, Optional Externally |

Port Usage Scenarios
Kinetica highly encourages that proper firewalls be maintained and used to protect the database and the network at large. A full tutorial on how to properly set up a firewall is beyond the scope of this document, but the following are some best practices and starting points for more research.
All machines connected to the Internet at large should be protected from intrusion. As shown in the list above, there are no ports which are necessarily required to be accessible from outside of a trusted network, so we recommend only opening ports to the Internet and/or untrusted network(s) which are truly needed based on requirements.
There are some common scenarios which can act as guidelines on which ports should be available.
Connection to the Internet
If Kinetica is running on a server where it will be accessible to the Internet at large, it is our strong suggestion that security and authentication be used and ports 9191+N and 8080 are NOT exposed to the public, if possible. Those ports can potentially allow users to run commands anonymously and unless security is configured to prevent it, any users connecting to them will have full control of the database.
Dependence on Kinetica via the API
For applications in which requests are being made to Kinetica via client APIs that do not use authentication, the 9191+N ports should be made available to the relevant set of servers. For applications using authentication via the bundled version of httpd, port 8082 should be opened. It is possible to have both ports open at the same time in cases where anonymous access is permitted, however the security settings should be carefully set in this case to ensure that anonymous users have the appropriate access limitations.
Additionally, if the API client is using table monitors or triggers, ports 9001, 9002, and/or 9003 should also be opened, as needed.
Reveal
In cases where the GUI interface to Reveal is required, the 8088 port should be made available.
Administration
System administrators may wish to have access to the administrative web interface, in which case port 8080 should be opened, but carefully controlled.
AAW
If the AAW package has been installed and access to the user interface is required, the 8070 port should be made available. If requests are being made to AAW via the API that do not use authentication, the 9187 port should be made available.
