This can be verified via the Client log. If the Agent is receiving UDP notifications, you will see lines containing “command received” such as the following in the logs:
- GatherActionMV command received
- GatherHash command received
- DownloadPing command received
Additionally, if you send the Client a refresh (right-click the computer in the Console and select ‘send refresh’), if the Agent is able to receive UDP notifications, you should see a line including:
- ForceRefresh command received
Note that aside from hardware firewalls, oftentimes the software firewalls associated with many newer OSes may block the UDP notification (Win7 has the Windows Firewall). We have a number of Fixlets in BES Support that might assist in identifying such cases as well as potentially re-configuring the firewall as needed to allow the traffic.
