IP information as a network path or IP address and netmask

You can define a trust based on the IP information of the computer that runs the PI interface or client application that you want to trust. To find the necessary information, you can run pidiag -host on the interface (or client) computer. This returns the connection credentials as retrieved from the local operating system.

You can specify IP information as a network path or IP address and netmask:

• Network Path. The fully-qualified domain name. For example, my_laptop.my_company.com

• IP Address. IP address of the interface computer (for static IP address only).

• NetMask. If you specify an IP address, you must also explicitly provide a netmask value. Failure to do so will generate an error. If you are requiring an exact match on an IP address, specify the netmask as 255.255.255.255. If you are specifying a Class C subnet, specify the netmask as 255.255.255.0 and the fourth field of the IP address as 0.

  Note: When applications run on machines with multiple network cards, it is unpredictable which credentials are sent to the Data Archive server for the trust authorization. AVEVA recommends that you either avoid such configurations, or create a PI trust for every IP address on the machine where the application runs.
