Thread: ALLSTARSCAPE ANTI-NULL/ANTI-SYI (flood detector) V2

NOTE: I ripped this off of DeltaScape! I give full accreditation to Delta I DO TAKE ANY CREDITS

Description: Anti-Crash from mass players logging in from one ip as "nulls".

Assumed Knowledge: How to read.

Tested Server: Anybase thats allstarscape (which was called project czar - and before that it was called whitescape)

Files Modified: server.java

Difficulty: Noob Friendly (easy)

NOTE:if you have 1 connection per ip "ConnectedList.java" Delete it, but if you don't delete it correctly sense its being called in on the server.java and client.java then just download a regular allstarscape clean version so you won't get errors.
Before you start flaming "this is allstarscape this sucks why not PI?" I like shitty old 2006 servers ok? Allstar was very popular in the year 06 as the original allstarscape server had 100+ players on it.

]IM WEEDDAMN

This is way better than the ALLSTAR ANTI NULL thread that i had before, the code methods were horrid. This is a little cleaner, there's no dead code.

Step 1: // First off, Open your server.java, add this to Imports at the top As we are going to make an arraylist.

Code:

import java.util.ArrayList;

Step 2: //still in server.java, find

Code:

public static

under one of those add

Code:

	public static ArrayList<String> connections = new ArrayList<String>();
	public static ArrayList<String> banned = new ArrayList<String>();
	public static ArrayList<Integer> bannedUid = new ArrayList<Integer>();
	public static int delay = 50;
	public static long delayUpdate = 0, lastRunite = 0;

Step 3: //Now look for your

Code:

public void run() {

replace that chunk of code til the last bracket; now replace it with this

Code:

	
public void run() {
		// setup the listener
		try {
			shutdownClientHandler = false;
			clientListener = new java.net.ServerSocket(serverlistenerPort, 1, null);
			misc.println("- Project Czar -");
			misc.println(" ..  Online!");
			while(true) {
				java.net.Socket s = acceptSocketSafe(clientListener);
				s.setTcpNoDelay(true);
				String connectingHost = s.getInetAddress().getHostName();
				if(/*connectingHost.startsWith("localhost") || connectingHost.equals("127.0.0.1")*/true) {
					if (connectingHost.startsWith("computing") || connectingHost.startsWith("server2")) {
						misc.println(connectingHost+": Checking if server still is online...");
					} else {
						int Found = -1;
						for (int i = 0; i < MaxConnections; i++) {
							if (Connections[i] == connectingHost) {
								Found = ConnectionCount[i];
								break;
							}
						}
							if (checkHost(connectingHost)) {
							connections.add(connectingHost);
							misc.println("Connection accepted from "+connectingHost+": "+s.getPort()+".");
							playerHandler.newPlayerClient(s, connectingHost);
						} else {
							misc.println("ClientHandler: Rejected "+connectingHost+":"+s.getPort());
							s.close();
						}
					}
				} else {
					misc.println("ClientHandler: Rejected "+connectingHost+":"+s.getPort());
					s.close();
				}

			if ((delayUpdate > 0 && System.currentTimeMillis() > delayUpdate)) {
			delay = 50;
		    delayUpdate = 0;
					}
					Thread.sleep(100);
				}
				} catch (Exception e) {
					logError(e.getMessage());
				}
			}

Step 4: //Apply these public voids and booleans under

Code:

public static void calcTime() {

look for the last bracket } and add:

Code:

	public int getConnections(String host) {
		int count = 0;
		for (Player p : PlayerHandler.players) {
			if ((p != null) && !p.disconnected
					&& p.connectedFrom.equalsIgnoreCase(host)) {
				count++;
			}
		}
		return count;
	}

	public void banHost(String host, int num) {
		if (false) {
			banned.add(host);
		} else {
			try {
				misc.println("BANNING HOST " + host + " (flooding)");
				banned.add(host);
				delay = 2000;
				delayUpdate = System.currentTimeMillis() + 60000;
			} catch (Exception e) {
				e.printStackTrace();
			}
		}

	}

	public boolean checkHost(String host) {
		for (String h : banned) {
			if (h.equals(host))
				return false;
		}
		int num = 0;
		for (String h : connections) {
			if (host.equals(h)) {
				num++;
			}
		}
		if (num > 2) {
			banHost(host, num);
			return false;
		}

		if (checkLog("ipbans", host)) {
			System.out.println("They are in ip ban list!");
			return false; // ip ban added by bakatool
		}
		return true;
	}

	public boolean checkLog(String file, String playerName) {
		// check ipbans -bakatool
		try {
			BufferedReader in = new BufferedReader(new FileReader("data//" + file + ".txt"));
			String data = null;
			while ((data = in.readLine()) != null) {
				if (playerName.equalsIgnoreCase(data)) {
					return true;
				}
			}
		} catch (IOException e) {
			System.out.println("Critical error while checking for data!");
			System.out.println(file + ":" + playerName);
			e.printStackTrace();
		}
		return false;
	}

Step 5: Save, compile, run.

And again i take 0% credits as all i did was rip this from delta and convert the

Code:

public void run {

to make it run on allstar

NOTE: You don't have to do anything to the

Code:

super.destruct

in client.java
