# Go Client-Server Test App
## What is This?
This application is a learning exercise for making a very simple UDP client and server in GoLang.
## How to Use
1. Install Go
1. Run the **server** with `./server.sh` (if you have bash) or `go run core.go udp-server.go`
* Optionally add a param for port, e.g. `./server.sh 40000`
* The server will start up and wait for data from the client(s).
* Server is very dumb, and just echoes data that it receives.
1. Run the **client** with `./client.sh` or `go run core.go udp-client.go` on a separate machine or separate terminal.
* Optionally add a param for host and port like `./client.sh example.com:40000` (default is localhost `127.0.0.1:40000`)
* The client will start up and await for your commands.
1. Enter any text, e.g., `Hello world`, on the client and hit enter. You should see the text sent from client to server, then echoed back from server to client.
1. Enter `STOP` to stop both the client and the server.
1. Enter `SEND` to begin continually sending data from the client to the server for 10 minutes.
* Purpose of this is to test the packet drop-rate.
* After the cycle stops the number of expected and received packets and bytes should be shown, and a `STOP` command will be issued.
* (Note: This is untested in a real environment.)
