public class Client {


public static void main(String args[])
{
String hostname = "";
String message = "";
String dnsserver_name = "10.0.7.218";
int dnsserver_port = 2020;
int server_port = 2010;

//create a buffered reader for reading the keyboard
BuffferedReader in = new BufferedReader(new InputStreamReader(System.in));
try{
System.out.print("Enter computer id:"));
hostname = in.readLine();
System.out.print("Enter messate to send");
message = in,readLine();
messate += " ";
System.out.pringln (Message);
