Before you begin any configuration related to Aloha Spy, you must identify an available TCP port for Aloha Spy to use for cross-network communication. Although TCP port 3999, the example used in this document, is almost always available, you should verify its availability before you use it.

NCR Voyix provides a utility called NetInfo.exe that you can use to verify a port is available, and to identify unused ports. This utility is available in the \Misc\NetInfo directory on an Aloha software installation CD, and from the Aloha FTP site. Copy the utility to the Aloha Back-of-House (BOH) file server, prior to use.

To test a specific port number for availability:

• Double-click Netinfo.exe to display the Network Information dialog box.
• Verify TCP is selected as the mask setting.
• Type the number of a port you want to use in the Port Number text box.
• Click Query Port to determine if the port is currently in use. The message, ‘No Service on this Port,’ appears in the Result text box if the port is not in use.If the port is currently in use, information appears in the Result text box indicating the port is in use. If individual ports queried using the previous procedure are in use, you can use the NetInfo utility to identify an unused port.

To identify an unused port:

• Click Get Service by Ports (TCP) in the NetInfo utility user interface. A list of ports in use appears in the list box below the button. This operation takes several seconds to complete.

• Select a port number not currently listed for use with Aloha Spy.

  Tip: We recommend a port in the range of 3000-3999.

• Click Exit.
