Hi Tom,
The Ubuntu is on Azure, So is it possible port scanning app is automatically installed by azure in ubuntu?
Regarding tcp values, do i need to keep current values or do you have any recommended values?
Thanks

Something port-scanning your server, perhaps? None of those
protocol numbers match anything that Postgres-related code
would use.
