I LIKE JAVA!

DO YOU?

If you don't it's o.k, nobody's perfect.

Nobody's perfect.

Nobody.

a quick portscan program in java (to make sure you don't have any loose ports on your computer).

import java.net.*;
public class Portscan{
 public static void main(String args[]){
  Socket socket;
  int port;
  boolean listen;      
  System.out.println( "Scanning all ports" );
   for( int i = 109; i<65535; i++){
    try{
     socket = new Socket( "localhost" , i );
     System.out.println( "Port " + socket.getPort() + " is NOT
secure.");
     socket.close();
    }catch( Exception e){
     System.out.println( "Port " + i + " is secure." );
    }
   }
  }
}

GUYS WITH HONOR

• Things I DID NOT do with this code
  1. Use it to scan all the ports on a host other than my own
  2. Add documentation
  3. Use a debugger
  4. Handle errors very well

Some of my favorite words
