[Release] AntiNameChanger

[zxz0O0]

As requested a plugin against name changers. It checks every 4-12 seconds if a player changed his name. When he did it a specific time an action will be taken.

Requires @Nukem's Server Addon 1.290+

sv_config.ini entries:

Code:

[NameChange] //After how many name changes action should be taken Changes=3 //Which action should be taken (kickClient, tempbanClient, banClient) Command=kickClient //Message to be displayed on server when an action is being taken, valid placeholder {0} = last name {1} = xuid //Example: Player {0} with the XUID {1} has been kicked ServerMsg= //Reason for action (displayed to the client when action is being taken) CommandMsg=

Source code

Code:

using System; using System.Collections.Generic; using System.Text; using Addon; using System.Threading; namespace AntiNameChanger { public class Class1 : CPlugin { //Store old names Dictionary<string, string> OldNames = new Dictionary<string, string>(); //Store name changes Dictionary<string, int> NameChanges = new Dictionary<string, int>(); //How many changes to take action int Changes = 3; string command = "kickClient"; string commandMsg = string.Empty; string srvMsg = string.Empty; public override void OnFastRestart() { OnMapChange(); } public override void OnMapChange() { OldNames.Clear(); NameChanges.Clear(); } public override void OnServerLoad() { try { ServerPrint("\n AntiNameChanger loaded \n Author: zxz0O0 \n Thanks to Nukem, Jariz and Pozzuh\n"); ServerPrint(" youtube.com/zxz0O0 \n itsmods.com\n"); Changes = int.Parse(GetServerCFG("NameChange", "Changes", "3")); command = GetServerCFG("NameChange", "Command", "kickClient"); srvMsg = GetServerCFG("NameChange", "ServerMsg", string.Empty); ThreadPool.QueueUserWorkItem(new WaitCallback(CheckWorker)); } catch (Exception e) { ServerPrint(e.Message); } } private void CheckWorker(object o) { Random i = new Random(); while (true) { int q = i.Next(0, 80); Thread.Sleep(4000 + q*100); CheckNames(); } } private void CheckNames() { try { foreach (ServerClient c in GetClients()) { //If player is already registred if (OldNames.ContainsKey(c.XUID)) { //If name didn't change if (OldNames[c.XUID] == c.Name) continue; //Else add to NameChanges int else { //If already stored increase value if (NameChanges.ContainsKey(c.XUID)) NameChanges[c.XUID]++; else NameChanges.Add(c.XUID, 1); //Store new name again OldNames[c.XUID] = c.Name; //Check if action should be taken if (Changes <= NameChanges[c.XUID]) { if (!string.IsNullOrEmpty(srvMsg)) ServerSay(string.Format(srvMsg, c.Name, c.XUID), false); ServerPrint("AntiNameChanger executed: " + command + " " + c.ClientNum + " \"" + commandMsg + "\""); ServerPrint("AntiNameChanger Last Name: " + c.Name); ServerCommand(command + " " + c.ClientNum + " \"" + commandMsg + "\""); } } } else OldNames.Add(c.XUID, c.Name); } } catch (Exception e) { ServerPrint(e.Message); } } } }

He said he would bypass this in a second. But this will work for the other 99%.

How can he bypass it when I use a random wait period

He is @SuperNovaAO He can do whatever sh#t he wants to...

Thanks Barata...

[surtek]

He can make a hack which randomly guesses these periods

thankyou

Weird that this hasn't been made before, good job!

Random() is pseudo random and the seed the server starts with can be calculated.

Then I make a Random()-generator with the same seed -> same random numbers.

But my server crash exploit is much more fun now.

Also, have you tried it?
