SpectroSERVER and OneClick Web Server Communication Across Firewalls

The OneClick web server communicates with processes on the ss host system to gather data to display in OneClick clients. The OneClick web server typically initiates this communication.

The OneClick web server communicates with processes on the
SpectroSERVER
host system to gather data to display in OneClick clients. The OneClick web server typically initiates this communication.
The OneClick web server establishes connections to specific
SpectroSERVER
host-side TCP ports. The web server uses these ports for sending requests and receiving responses. However, OneClick uses a single listening port (default 14001). The
SpectroSERVER
initiates the connection to that port. As a result, modifying firewall configuration is often necessary. The
SpectroSERVER
uses bidirectional IIOP (Internet Inter-ORB protocol) to communicate with its CORBA clients.
The following diagram illustrates the IP connectivity that is required for a OneClick web server to communicate with a
SpectroSERVER
. In all cases where TCP is used, the connections are established from a random port to a specific, fixed port.

In a Fault-Tolerant configuration, the same ports must be opened between the OneClick Server Host and the secondary SpectroSERVER Host, including port 14003 if running a secondary Archive Manager.
