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 |
| 5432 | The listener for PostgreSQL Wire Protocol connections | Head | Optional Externally |
| 5552 | Host Manager status notification channel | All | Required Internally |
| 5553 | Host Manager message publishing channel | All | Required Internally |
| 6555+N | Provides distributed processing of communications between the network and different ranks used in Kinetica. There is one port for each rank running on each server, starting on each server at port 6555 and incrementing by one for each additional rank. | All | Required Internally |
| 7002 | This port must be open to collect the runtime system statistics. | All | Required Internally |
| 8000 | The Tomcat listener for the Workbench user interface. | Head | Optional Externally |
| 8005 | The Tomcat shutdown port for the Kinetica Administration Application (GAdmin) user interface. This port should not be exposed publicly. | Head | Required Internally |
| 8006 | The Tomcat shutdown port for the KAgent user interface. This port should not be exposed publicly. | Head | Required Internally |
| 8009 | The Tomcat AJP connector port for the GAdmin user interface. | Head | Required Internally |

| 8081 | The Tomcat listener for the KAgent user interface. | Head | Optional Externally |
| 8082 | In installations where users need to be authenticated to access the database, a preconfigured HTTPd instance listens on this port, which will authenticate incoming HTTP requests before passing them along to Kinetica. When authorization is required, all requests to Kinetica should be sent here, rather than the standard 9191+ ports. | All | Optional Externally |
| 8088 | This is the port on which Kinetica Reveal is exposed. For installations that have this feature enabled, it should be exposed to users. | Head | Optional Externally |
| 8099 | This is the port used for pushing data to the graph server (if enabled) | Head | Required Internally |
| 8100 | This is the port used for pulling data from the graph server (if enabled) | Head | Required Internally |
| 8181 | This is the port used to host the system and process stats server | Head | Optional Externally |
| 8443 | The Tomcat listener for the GAdmin user interface using SSL. | All | Optional Externally |
| 8444 | This is the port on which Kinetica Reveal is exposed using SSL. For installations that have this feature enabled, it should be exposed to users. | Head | Optional Externally |
| 8445 | This is the port on which Kinetica Workbench is exposed using SSL. For installations that have this feature enabled, it should be exposed to users. | Head | Optional Externally |
| 9001 | Database trigger ZMQ publishing server port. Users of database triggers will need the ability to connect to this port to receive data generated via the trigger. | Head | Optional Externally |
| 9002 | Table monitor publishing server port. Users of database table monitors will need the ability to connect to this port to receive data generated via the table monitor. | Head | Optional Externally |
| 9003 | Table monitor internal publishing server port. Users of database table monitors on tables that are the targets of multi-head ingest will need to allow worker nodes the ability to connect to this port to receive data generated via the table monitor. | Head | Optional Internally |
| 9010 | Host collector metrics port. CPU, disk, processes, and other metrics are collected from the /proc filesystem and posted here. | All | Required Internally |
| 9080 | Port used to host Grafana Loki, a log aggregation system. | All | Required Internally |
| 9089 | Port used to host the Alert Manager, which manages alerts from Grafana Prometheus and events from Grafana Loki. | All | Required Internally |
| 9090 | Port used to host Grafana Prometheus, a metric aggregation system. | All | Required Internally |
| 9091 | Port used to host the Grafana user interface and embeddable metric dashboards in GAdmin. | All | Required Internally, Optional Externally |
| 9187 | The primary port used for communications with KML. This port should be exposed for any system using the KML API without authorization. | All | Required 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 |
| 9300 | Port used to query Host Manager for status | All | Required Internally |
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.
