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
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

8080	The Tomcat listener for the GAdmin user interface.	All	Optional Externally
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 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
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
9187	The primary port used for communications with AAW. This port should be exposed for any system using the AAW API without authorization.	All	Required Internally, Optional Externally
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.

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.
