package myservertrial1;

package myservertrial1;

import java.io.*;
import Proxy.Proxy;
 
public class Main {
 
    /**
     * @param args the command line arguments
     */
    static ServerSocket MainSocket = null;
    final static int defaultPort = 8080;
    final static int maxPort = 65536;
 
    public static void main(String[] args) {
        // TODO code application logic here
        int daemonPort;
 
        // Parse command line
        switch (args.length) {
            case 0:
                daemonPort = defaultPort;
                break;
 
            case 1:
                try {
                    daemonPort = Integer.parseInt(args[0]);
                } catch (NumberFormatException e) {
                    System.out.println("Error: Invalid daemon port");
                    return;
                }
                if (daemonPort > maxPort) {
