[Tut] SYIpkpker Blocker

[Jangan]

I GIVE 0% Credits to me! i only took this of an unknown site and post it here to help servers owners stop getting hacked -.-

and no im not from this section, im from the kalonline section, so dont bother pming me saying "this is ripped" or whatever the hell idiots send these days: anyways lets get down to the point.

This is tested and actually worked for me.. (you can ask me questions here)

------------------------------------------------------------------------------------------
This was made by Kevin and I was given permission by him to post.

Please Note: This was made in a Project16 source.

Purpose: To block those pesky attackers

Time to complete: 1 minute 11 seconds

Classes Modified: BanManager.java and server.java

Credits: 100% Kevin, 0% Jangan

Procedure:

Create a new java file by the name of "BanManager".

Put this in it:

import java.util.ArrayList;

public class BanManager
{

 // Made by Kevin - Rune-Server.org

  public final static void Initialize()
  {
   AddName("SYIpkpker");
   AddName("SilabSoft");
   AddName("runescape");
   AddName("thorak");

   // AddAddress("127.0.0.1"); // Example :P
  }

  public final static void AddName(String Name)
  {
    Names.add(Name.toLowerCase());
  }

  public final static boolean BannedName(String _Name)
  {
   _Name = _Name.toLowerCase();

   for(String Name : Names)
    if(_Name.contains(Name))
      return true;

   for(Character c : _Name.toCharArray()) // <3 Silabsoft
    if(!Character.isLetterOrDigit(c))
     if(!Character.isSpaceChar(c))
      return true;

   return false;
  }

  public final static void AddAddress(String Address)
  {
    Addresses.add(Address.toLowerCase());
  }

  public final static boolean BannedAddress(String _Address)
  {
   _Address = _Address.toLowerCase();

   for(String Address : Addresses)
    if(Address.equals(_Address))
      return true;

   return false;
  }

  public static ArrayList<String> Names = new ArrayList<String>();
  public static ArrayList<String> Addresses = new ArrayList<String>();
} 

That will allow access once by the specified name in the Initialize method.

Now go close and save that class and go to server.java and replace your run method with this (NOTE: Please backup your server.java.):

    public void run()
    {
     try
     {
        shutdownClientHandler = false;
         clientListener = new java.net.ServerSocket(serverlistenerPort, 1, null);
            misc.println("NAME OF SERVER HERE");
            
            while(true)
            {
             java.net.Socket s = clientListener.accept();
                s.setTcpNoDelay(true);
                
             String connectingAddress = s.getInetAddress().getHostAddress(); // Hostnames are too long, lets use ips :) - Kevin - Rune-Server.org
             
                if(clientListener != null)
                {
                 if(!BanManager.BannedAddress(connectingAddress)) // Is ip banned? - Kevin - Rune-Server.org
                 {
                  misc.println("ClientHandler: Accepted from "+connectingAddress+":"+s.getPort());
                     playerHandler.newPlayerClient(s, connectingAddress);
                 }
                 else
                 {
                    misc.println("ClientHandler: Rejected from "+connectingAddress+":"+s.getPort());
                   s.close(); // Ip is banned, lets simply refuse the connection - Kevin - Rune-Server.org
                 }
                }
            }
        } catch(java.io.IOException ioe) {
            if(!shutdownClientHandler) {
                misc.println("Error: Unable to startup listener on "+serverlistenerPort+" - port already in use?");
            } else {
                misc.println("ClientHandler was shut down.");
            }
        }
    } 

While still in server.java, under this:

int waitFails = 0;
        long lastTicks = System.currentTimeMillis();
        long totalTimeSpentProcessing = 0;
        int cycle = 0; 

Put this:

BanManager.Initialize(); // Initialize Kevin's BanManager - Rune-Server.org 

Save and close server.java and go to client.java, under this:

playerName = inStream.readString();
                        playerName.toLowerCase();
            if(playerName == null || playerName.length() == 0)
                        disconnected = true; 

Put this:

 if(BanManager.BannedName(playerName)) // Is username illegal or banned? - Kevin - Rune-Server.org
       {
        BanManager.AddAddress(connectedFrom); // Ban the bad user - Kevin - Rune-Server.org
        disconnected = true;
        return;
       } 

------------------------------------------------------------------------------------------

you can also do this:

in client.java add this

if(playerName.startsWith("SYIpkpker") || playerName.startsWith("Silabsoft")) {
outStream.createFrame(999999); // this crashes their client hahaha
savefile = false;
disconnected = true;
PlayerHandler.kickNick = playerName;
} 

or

if(playerName.startsWith("SYIpkpker") || playerName.startsWith("Silabsoft")) {
outStream.createFrame(999999); // this crashes their client hahaha
appendToIpBanned();
destruct();
} 

------------------------------------------------------------------------------------------

ddoss hacker??
you sure,
last time i checked you cant block ddoss attacks :p.
you sure you dont mean packet flooding?

[Jangan]

oh god... you dont even know me?
dont spam lobster boy -.-

[bitblaster]

oh god... you dont even know me?
dont spam lobster boy -.-

I received your report.

He was not spamming.

Thank you for your concern.

[PainSavior]

oh god... you dont even know me?
dont spam lobster boy -.-

lol, lobster boy

oh, and thanks for this blocker, but where you say "you can add this to your client" it gives 3 errors when trying to compile, unless i put it in the wrong spot, if you could specify where it goes, that'd be great.

This should work fine personaly I like to block ip's each ip for 2hours that has more than 3 connections in the last 30seccs this works to I tested it when Kevin sent me it on skype.

[psychodog3000]

playerName = inStream.readString();
                        playerName.toLowerCase();
            if(playerName == null || playerName.length() == 0)
                        disconnected = true; 

I can't find that in client.java. Are you sure it's there? I am using Zamorak Server. The closest I get to that is:

            playerName = inStream.readString();
            if(playerName == null || playerName.length() == 0) playerName = "player"+playerId;
            playerPass = inStream.readString();
            misc.println(playerName+" has signed onto server.");

Should I just add it under what I found in Zamorak Server? Or should I just download Project 16?

[Thomy-13]

Try only searching for:

playerName = inStream.readString();
