Ok, I’m back at my console.
From the BES Asset Discovery site, execute Task 21 “Change Nmap Asset Discovery Server Settings” and use the parameter “0” to include BES Clients.
A little more detail on the under-the-cover issue with finding BES clients…the NMap scan attempts a UDP connection to port 52311, where a BES Client should be listening for notifications about new content from the parent relay. The client does not send replies to the UDP message (and should not, based on how our notification process works), but … NMap is expecting an ICMP response for “port unavailable” if there was not process (BESClient) listening on the port.
Modern versions of Windows and Linux generally don’t send those ICMP “port unavailable” responses anymore, which breaks NMap’s ability to tell whether the BESClient process is running or not. So now we pretty much always need to set this option to include existing BigFix clients.
Now that you’ll be including the existing BES Clients as Unmanaged Assets, you may also want to use Task 31 “Change UAImporter Delete Mode” to manage what happens when you delete an unmanaged asset and it reappears again in a future scan. If you set “delete” mode, the info is removed from the database and if it’s found again in a future scan it is recreated; if you set “ignore” mode, the info stays in the database but it is marked as non-visible, and won’t come back to the console again if it appears in a future scan.
