/**
 * File transfer between master server and satellite server.
 * The connection should always be from satellite to master, because of
 * open port knowledge on master server.
 * 
 * For uploading file to master, satellite should send a request with
 * token "U" for want upload. --> start Uploader(IP, PORT).
 * 
 * For downloading a file from master, satellite should send a request
 * with token "D" for want download. --> start Downloader(IP, PORT).
 * 
 * Means the master server has to start the opposite part:
 * If master receives token "U" --> start Downloader(socket)
 * If master receives token "D" --> start Uploader(socket)
