So at ArcGIS 10, ESRI adopted Flexera's FlexNet Publisher Trusted Storage module for secure exchange of license file "fulfillment records" and transfer of product activations.
Question what network traffic occurs and what corresponding firewall ports should be open to allow the traffic to pass? Also, what conflicts will arrise with other applications running the same FlexNet Publisher licensing tools--Autodesk, SolidWorks, Adobe, etc. and how best to make things coexist?
The FLexNet Publisher License Administration Guide doesn't address those specifics. And when looking at the ArcGIS 10 installations you'll now see a FLEXNetLicensingService.exe running and calls to libFNP.dll on license server and client. That in addition to the "old" FlexNet Publisher lmgrd.exe and ESRI's FlexNet ARCGIS.EXE Vendor daemon on the license server.
How does it all behave? And how do we fix it when collisions or version conflicts occur?
A very scary thing is that a number of Apps using FNP are placing configurations and executable files into the common directory:
C:\Program Files\Common Files\Macrovision Shared\FLEXnet Publisher
Where vendors can do what they want and update their FlexNet components at their convenience, without regard for release level of other applications present on the system. Looking at the FLEXERA site I don't have a sense that they make much of an effort to support the end users. License exchanges over VPN has been especially troublesome for end users.
