    Hi Slartybardfast 

    I suspect what you are seeing is a known issue with OpsCenter which is looking to intererogate all known clients via the master server. If this is the case there is a EEB available for this - log a support call and reference ET3983346 (assuming you are on 8.1.2, or ET3980658 for 8.2). 

    You should be able to test this theory by disabling OpsCenter for a period and observe whether you see the suprious connections. If you don't have OpsCenter installed and monitoring the environment, then I'm not sure what it could be.

    I first saw this back in Dec 2019 with a new NetBackup customer (predominantly VMware) who was wondering exactly the same as you.

    Hope this helps
    David

    Good Morning David,

    Yes we do have OpsCenter 8.2 installed. Wow you learn something new every day. I would have never have suspected or even looked at OpsCenter. I will log a call and get the EEB you referenced in your reply. Thank you good Sir :)
