Class UFTPServer

java.lang.Object

eu.unicore.uftp.server.UFTPServer

All Implemented Interfaces:

Runnable

public class UFTPServer
extends Object
implements Runnable

Server for sending/receiving data using dynamic port opening in firewalls via a pseudo-FTP connection. A ServerThread is started, which waits for incoming client requests. At the same time, the server listens on a command-socket, waiting for UFTPTransferRequest requests. Client requests are linked to jobs, i.e. only clients announced via a Job are accepted.
Authorization:
Each job has an associated "secret", which the client has to know.
