Usage and Config Platform
1

Hello All,
I’m facing issue in my environment that i.e action to few servers are going fast and on few servers actions are not reaching even after 14hrs. When i checked with PMR they are telling that issue is due to UDP and TCP port are blocked.

Is there any way to find which are the servers are blocked with TCP and UDP port 52311.
I have all flavours of OS in my environment AIX, Linux, Windows and Solaris.

Thanks in advance.

Also, you might consider enabling Command polling

Hi Aram, Problem in enabling Command polling, When patching activity going in server end suddenly command polling getting enabled and starts gathering. Patching activity puts on hold (patching window is limited). So we dont want to enable Command Polling.
Is there any way to find UDP and TCP port open in endpoints?

In my post above, I reference an analysis on bigfix.me that can give you an indication as to whether or not Clients are receiving notifications (i.e. if the Client is receiving UDP messages). This can be used by itself as a means to address Clients not receiving UDP messages due to firewalls, etc…without necessarily enabling command polling.
