Currently I have a small problem, but that takes a lot of time.
This is the control of network flows. Specifically, check that every time I have a new machine, flows and ports have also been opened to other machines.
The problem therefore is not only to verify that the flow is present, but also to simulate it. For example, if server A needs to talk to server B via port 9191, I need to be able to test this flow without the need to actually install the application.
I know that there is nc that can simulate listening to a port, but I would like to know if it exists in ansible, or if you have used a tool that allows you to check and test these flows.
Also because the problem is to define all the relationships between the servers and their ports.
I thank you for the time you want to dedicate to me
