About NiagaraAX ports
As with most Internet-enabled applications, the applications running on NiagaraAX hosts also use default ports for communication with clients (typically other NiagaraAX hosts, or BUI users). For instance:
- a browser client that connects to a Px Page does so on port 80 of a NiagaraAX host running WebUI services (the port is configurable in the station’s WebService properties).
- an engineering PC (the client) uses workbench to connect to a station for maintenance, by default Fox port is 1911.
- an engineering PC (the client) uses the Platform Tool to change an IP address on the host, and connects on the host’s daemon port 3011.
Table 1 provides a list of the types of communication used by NiagaraAX hosts, and the default server ports used. Unless otherwise noted:
- the client randomly chooses an available client-side port (1024 or greater) to talk to the listed server port
- the server port listed is a TCP port (rather than a UDP port)
- most of the ports in the table are constantly open. Some applications (such as FTP, or the NiagaraAX web server) may constantly keep a port open, which means the port is scannable by a port scanner. Other ports (such as the host Admin port) only are shown when they are in use.
