Matthew F Posted November 19, 2012 Share Posted November 19, 2012 I'd like to allow mobile clients to "register" their devices to allow access to a solution hosted on Filemaker Server. 'Get(SystemNICaddress)' seems to return the address of the server, not the client. Any suggestions for how to uniquely identify clients, or to store a local registration number? I'm looking for a convenient and reliable system, not high security. Link to comment Share on other sites More sharing options...
Ocean West Posted November 19, 2012 Share Posted November 19, 2012 Get(PersistentID) Returns text representing a unique identifier of the computer or device on which FileMaker is running. http://www.filemaker.com/12help/html/func_ref2.32.54.html Link to comment Share on other sites More sharing options...
Matthew F Posted November 19, 2012 Author Share Posted November 19, 2012 Thanks for your reply. I tried Get(PersistentID) but, in a Server/Client setup, it returns the same ID for each device. I assume it is the ID of the server, not the client. Link to comment Share on other sites More sharing options...
Steven H. Blackwell Posted November 19, 2012 Share Posted November 19, 2012 Are you sure that it does that? Is the calculation unstored? Also, the key word in the definition of Get(PersistentID) is representing. Steven Link to comment Share on other sites More sharing options...
Matthew F Posted November 21, 2012 Author Share Posted November 21, 2012 Thanks for your input. Changing the calculation from "Not indexed" to "Unstored" now gives me a different ID on different devices. I guess that was the issue. Link to comment Share on other sites More sharing options...
comment Posted November 21, 2012 Share Posted November 21, 2012 Also, the key word in the definition of Get(PersistentID) is representing. I wonder what that means. I wish FMI would provide better documentation; as it is now, the only way to find out which parts of the hardware are "represented" in the ID is to take them out and see if the result has changed (assuming only hardware affects the result - we can't even be sure of that).

Steven H. Blackwell Posted November 21, 2012 Share Posted November 21, 2012 What it means is that the Get(PersistentID) result is not a UUID from something on the hardware itself. It's a hashed result. It still returns the same value for each query to the same machine. IIRC, they made mention of this at the 2010 DevCon in San Diego.

comment Posted November 22, 2012 Share Posted November 22, 2012 It's a hashed result. Thanks, that's an interesting tidbit. I'd still like to know what exactly defines "the same machine". Link to comment Share on other sites More sharing options...
marioantonini Posted April 30, 2013 Share Posted April 30, 2013 I know this might be a bit old, but I would like to know if it has been explained somewhere what "the same machine" means? Specially regarding PCs running Windows. Link to comment Share on other sites More sharing options...
mikeym Posted May 17, 2013 Share Posted May 17, 2013 I also wouldn't mind knowing more about this function as well. Wouldn't it have to be at least partially hardware based? If not, would wiping a FMP install and re-installing result in a different PersistentID? Link to comment Share on other sites More sharing options...
