How to disconnect from localhost?

Question

Is it possible to disconnect from localhost?

I'm writing a Node.js WebSocket server, and I want to test locally what would happen if the connection closes erroneously.

If I were testing remotely, I'd just Turn Wi-Fi Off, but that doesn't disconnect my connection to localhost.

Thoughts?

Answer 1

localhost is just an alias in your hosts file. If you remove that alias then you'll be effectively "disconnecting" from localhost.

Answer 2

I don't know of any way you would do what your asking except perhaps to block the ports or the program you are running on your localhost via its firewall.
