Ports and Connections

The following describes all connections and default listening port numbers that are important for any system/network administrator to know of. However, it is recommended to run the system on a network without firewalls if possible.

Port

Protocol

Description

102

TCP

Viz World Server listener port for Viz World Client connections when Server Allocator is not in use or only has one Viz World Server running.

103

TCP

Viz World Server listener port for configuration tool connections to the first Viz World Server instance (as configurations are controlled by the first server instance).

10100

TCP

Server Allocator listener port for Viz World Client connections, and is only used in order for clients to get connection details about Viz World Server(s).

The first client connection is always diverted to port 102. In case of Multiple Server Instances, port numbers are assigned according to a predefined schema. In case there is no Server Allocator, Viz World Server switches to port 102.

10100

UDP

Viz World Server listener port for Server Allocator communication.

10200

UDP

Server Allocator listener port for Viz World Server communication.

10300

HTTP

Viz World Server listener port for Server Allocator communication.

Both UDP ports are internal ports used between the servers.

Multiple Server Instances

If a machine is running multiple Viz World Server instances every extra instance (second and above) opens other ports by this formula:

  • Viz World Server listener port (TCP): 10100 + ID – 1.

  • Server Allocator listener port (UDP): 10200 + ID – 1 (this is an internal port between servers) (where ID indicates the instance, for example the third server, ID = 3).

  • Server Allocator listener port (HTTP): 10300 + ID – 1 (this is an internal port between servers) (where ID indicates the instance, for example the third server, ID = 3).

If four Viz World Server instances are configured, the following listener ports are used:

  • 102 (TCP): First instance.

  • 10101 (TCP): Second instance.

  • 10102 (TCP): Third instance.

  • 10103 (TCP): Fourth instance.

  • 10100 (TCP): Viz World Client(s) connection to the Server Allocator.

  • 103 (TCP): Configuration tool connection to the Viz World Server.

Internal ports used by Server Allocator and Viz World Server(s) to communicate between themselves:

  • 10100 (UDP): Server Allocator.

  • 10200 (UDP): First instance.

  • 10201 (UDP): Second instance.

  • 10202 (UDP): Third instance.

  • 10203 (UDP): Fourth instance.

  • 10301 (HTTP): First instance.

  • 10302 (HTTP): Second instance.

  • 10303 (HTTP): Third instance.

  • 10304 (HTTP): Fourth instance.
