Hello World

A simple application using SCION that sends one packet from a client to a server.

Server:

go run helloworld.go -port 1234

Client:

go run helloworld.go -remote 17-ffaa:1:a,[127.0.0.1]:1234

Replace 17-ffaa:1:a with the address of the AS in which the server is running.

Walkthrough:

This SCION application is very simple, and it demonstrates what is needed to send data using SCION:

1. Validate command-line arguments.

Server: 2. Open listener connection (appnet.ListenPort). 3. Read packets from connection. 4. Close listener connection.

Client: 2. Open client connection (appnet.Dial). 3. Write packet to connection. 4. Close client connection.
