Notify client about changes in database in Java

I’m working on a distributed client-server system that uses TCP. The program’s functions is to transfer money to an from the server, but also between the clients, a sort of MobilePay.

Async network programming using Reactive Extensions

After doing some (more-or-less) “low-level” async socket programming years ago (in an Event-based Asynchronous Pattern (EAP) fashion) and recently moving “up” to a TcpListener (Asynchronous Programming Model (APM)) and then trying to move to async/await (Task-based Asynchronous Pattern (TAP)) I’ve pretty much had it with keep having to bother with all this ‘low level plumbing’. So I was figuring; why not give RX a go (Reactive Extensions) since it might fit more snugly to my problem domain.

TCP Max SEQ number +1

I’m reading about TCP at the moment and there is a maximum sequence number 2 ^ 32, my question is what happens when the other host tries to send an acknowledgement for that sequence number 2 ^ 32 + 1?

listening to packets in promiscuous mode

I am working on an application that get packets that don’t belong to the pc,so i use promiscuous mode on my NIC,i need to read the packet and and handle it.
