Finger Protocol problem

[DeNiS_M]

Hello guys.

I'm writing a simple finger client.
Here is the code:

/**
 * Project: SocketExamples
 * File: JFinger.java
 * Created on: 19 Sep 2011
 */
package example1;

import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.Socket;

/**
 * @author denis
 */
public class JFinger
{
	private static final int DEFAULT_PORT = 79;
	private static String host;

	
	/**
	 * @param args
	 */
	public static void main(String[] args)
	{
		Socket connection = null;
		try
		{
			host = args[0];
			connection = new Socket(host, DEFAULT_PORT);
			OutputStreamWriter out =
				new OutputStreamWriter(connection.getOutputStream(), "8859_1");
			out.write("finger "+host);
			InputStreamReader in =
				new InputStreamReader(connection.getInputStream());
			int c = 0;
			while ((c = in.read()) != -1)
			{
				System.out.println((char) c);
			}
			in.close();
			out.close();
		}
		catch (IOException ioe)
		{
			System.out.println("Exception opening connection: "+ioe.getMessage());
                        ioe.printStackTrace();
		}
		catch (ArrayIndexOutOfBoundsException aiobe)
		{
			System.out.println(aiobe.getMessage());
		}
		finally
		{
			try
			{
				if (connection != null)
					connection.close();
			}
			catch (IOException e)
			{
				System.out.println("Exception closing socket: "
					+ e.getMessage());
			}
		}
	}

}

The problem i suspect lies in the fact that i can't bind the connection object in port 79
resulting in an IOException (line 47) although i run the program in super user mode.
I used netstat to see if an other service listen on that port but no one would.

I can't think what might be wrong so i would like your help to solve this issue.

Thanks

Here is the output of my tests.
