Hello World

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

Server:

go run helloworld.go -listen 127.0.0.1:1234

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:

Server:

1. Open listener connection (pan.ListenUDP).
2. Read packets from connection (conn.ReadFrom).
3. Write reply packet (conn.WriteTo).
4. Close listener connection.

Client:

1. Open client connection (pan.Dial).
2. Write packet to connection (conn.Write).
3. Read reply packet (conn.Read), with timeout
4. Close client connection.
