Java networking: how to simulate two different computers?

Question

I want to start network programming in Java. What's the best way to go about it in terms of testing? If I write a client and server program, I'd obviously want to test them in either a real or simulated network environment, but I only have one computer.

Am I missing something or is there a standard tool used for this?

Answer 1

Use local port for both server and clients to connect to. You can simulate multiple machines easily.

Answer 2

您可以尝试使用虚拟机，例如VirtualBox 。

Answer 3

如果您无法获得另一台计算机，那么我将首先使客户端和服务器都在同一台计算机上工作，并且也许最终会使用一个或多个vmware映像来进行更多模拟。

Answer 4

You don't need a virtual machine; you can create a virtual interface, that's much easier and won't eat half of your RAM.
