3.5/3.7 Chat Server Help

**whiteone** · 04-04-13

Was wondering if anyone might have some idea's as to why my chat servers seem's to be in a authentication loop. Been messing with it for a few days and no luck I've added some logging on the chat server side and here is what i'm getting.

Game Server Console

Code:

02:16:12.627 INFO [pool-3-thread-6]: - Connected to ChatServer!
02:16:12.657 INFO [pool-4-thread-3]: - GameServer authed successfully IP : 192.168.1.100 Port: 10241

I've also tried localhost and 127.0.0.1 it connects fine but still the same results

Chat Server Console

Code:

INFO [04 Apr 02:28:02,405] Player registered from server side 98964
INFO [04 Apr 02:28:02,405] SM_PLAYER_AUTH_RESPONSE opcode and token
INFO [04 Apr 02:28:16,662] Player registered from server side 98964
INFO [04 Apr 02:28:16,663] SM_PLAYER_AUTH_RESPONSE opcode and token
WARN [04 Apr 02:28:29,516] Received logout event without client authentication for player 98964
INFO [04 Apr 02:28:29,517] Player logout 98964

Repeats every 10 seconds minus the logout

Packet Samurai

Code:

144	+9707 ms	10	CM_CHAT_AUTH
1E6	+9707 ms	52	SM_CHAT_INIT

Repeats every 10 seconds and the packet structs look right.

As you can see from the chat server console it is talking but it seems to be failing on the client authentication.

When running wireshark i'm not seeing any traffic on ports (tcp.port == 10241) || (tcp.port == 9021) between the client and Chat Server.

Please, go take a look in your Chat server folder. I've been coding a very long time and just stepped into the Aion area yesterday.
But I've downloaded and examined over 5 versions of these different emu's. Still trying to find a decent setup, not had the time to test each of these, just examine them. I've also noticed that in 2 of these, that inside one of the startup scripts for the Chat server itself, that the script does in fact refresh every 10 seconds. It is how it monitors Chat.

If you don't mind, could you please look inside those files found in your primary Chat server folder (startup folder) with the files ending in .bat and .sh. Open them in notepad or whatever your favorite editor of choice may be. Look for where it mentions that it refreshes every 10 seconds. If you find this, you'll see it was designed to monitor chat at this speed.

This may or may not be the case for you, again I just started examining the code yesterday.
I plan on finding one 3.0.x solution and going with it.

On a side note, I have an additional question:
Do your mobs respawn if you loot the corpses right away?
If yes, would you be so kind as to point me to which version of the emu your using?
Thank you in advance for your responses.

*For those that do not know me*
I'm an older guy, over 40, been writing emulators' for very large mmo's for nearly 27 years, I hope to be of use in this section.

----------Edit with snippet-----------
For example Aion-Lightning-2 from code.google blah blah
(Notice the sleep command for 10 seconds here as an example)

The following is found in trunk\AL-CServer\dist\cserver_loop.sh

Code:

#!/bin/bash

err=1
until [ $err == 0 ];
do
	/home/java/bin/java -Xmx512m -cp ./libs/*:al-cserver-1.0.0.jar com.aionemu.chatserver.ChatServer > log/stdout.log 2>&1
	err=$?
	sleep 10
done

PS, it could very well be built into the packet samurai jar file.

From looking through the code some more the CM_CHAT_AUTH & SM_CHAT_INIT should only be sent once every time you log into the game world which is leading me to believe that the client is not authorizing at some point. Did some packet capturing of live and a few other PS which have chat working and it's only sending them once. So need to find which step it failing at.

Someone older then me LOL just kidding i turn 40 in a few months. I mainly have worked with C++ & lua this is my first time working on a java built EMU really doing it more to learn it so it has been interesting.

Do your mobs respawn if you loot the corpses right away?

Not right away they respawn about the same rate as live.

If yes, would you be so kind as to point me to which version of the emu your using?

I'm using a 3.5 core converted to handle 3.7 so i can actually log in with the current live aion client.

I'm using the following two download. They do need some work to get working correctly mainly just updated opcodes and some struct changes so far nothing to bad except for the ChatServer.

Server
File-Upload.net - 3.5.0-server.rar ** Click the download button above where it say's Tip: Upload Pic!

ChatServer
File-Upload.net - chatserver.zip ** Click the download button above where it say's Tip: Upload Pic!

Core
3.5.0.rar — Yandex.Disk

Here is the thread i got the two links from to give them credit.
Anarchy 3.5.0 ls gs - page 2 - Other Release projects Aion-Finish 3.7 Dev Team

I also had to use Java SDK 6U41 i got the 64bit version from the following since java site was being difficult with there older version.

Thank you very much.
I'll download and start looking through this as well.
May as well have two people digging through it than one. :-)
Give me a couple hours to get this downloaded, configured, and some time to examine how its behaving.

Cheers

PS Yes, I left the age comment alone lolol :-)

Here it is in 3.5.0\Game\src\com\aionemu\gameserver\network\aion\clientpackets\CM_CHAT_AUTH.java

Code:

package com.aionemu.gameserver.network.aion.clientpackets;

import com.aionemu.gameserver.configs.main.GSConfig;
import com.aionemu.gameserver.model.gameobjects.player.Player;
import com.aionemu.gameserver.network.aion.AionClientPacket;
import com.aionemu.gameserver.network.aion.AionConnection.State;
import com.aionemu.gameserver.network.chatserver.ChatServer;

/**
 * Client sends this only once.
 * 
 * @author Luno
 */
public class CM_CHAT_AUTH extends AionClientPacket {

	/**
	 * Constructor
	 * 
	 * @param opcode
	 */
	public CM_CHAT_AUTH(int opcode, State state, State... restStates) {
		super(opcode, state, restStates);
	}

	@Override
	protected void readImpl() {
		@SuppressWarnings("unused")
		int objectId = readD(); // lol NC
		@SuppressWarnings("unused")
		byte[] macAddress = readB(6);
	}

	@Override
	protected void runImpl() {
		if (GSConfig.ENABLE_CHAT_SERVER) {
			// this packet is sent sometimes after logout from world
			Player player = getConnection().getActivePlayer();
			if (!player.isInPrison()) {
				ChatServer.getInstance().sendPlayerLoginRequst(player);
			}
		}
	}
}

I'm wondering if it's not liking the token that is sent back in SM_CHAT_INIT from the chatserver.

Your positive your using the same opcode for Chat as you are in (Game and Login)?
I know you mentioned more up to date with current client, could be the issue.

**whiteone** · 04-04-13

Ops i forgot the most important part the chatserver i don't remember where i got the original link from but here it is.

ChatServer
File-Upload.net - chatserver.zip

That opcode is only set in the Game Server and is just used for the initial communication then it get's handed off to the chat server which is on a different port 10241 & 9021 with it's own set of opcodes and from what i can tell by capturing them on live and live compatible private servers with wireshark those look fine since those are not encrypted.

I just downloaded the other pieces and was looking lol.
Give me a bit to grab lunch and setup up the configs and I'll give it a whirl.

Not spamming every 10 seconds.

I can click on each of the channels and it will switch unlike with Chat server off.
I am not level 11 yet, but it is successfully logging.

What worked / didn't work:
(Click me) Opens new window/tab with thread relevant to this topic.
This server runs fine with chat server, but not the one I downloaded from you. So it is something in the source files. Definitely game server library file related. At least its a starting point for narrowing it down. Compare libraries between the two builds that have to do with communication.

What did work:
Ran it against Aion-Lightning 3.0 from the link a few lines up. Worked perfectly.

Output from my chat window after logging into the game:

Spoiler:

Ahh i should have thought about trying a lower client version. Humm now the fun part trying to get it to work with the live client. This helps at least i know the chatserver works. :)

**DNC** · 04-04-13

I was wrong bro, look at my edit. I had accidentally ran the wrong server.
Tested with yours failed.
Tested with the edited post one, worked flawlessly.

EDIT Not sure about client yet, I do not have a fully built one to test with. My client is 3.0.0.8

**whiteone** · 04-04-13

I'm leaning toward this in the ChatService.java going to throw some more logging in there when i get home tonight can't really do it since i'm at work.

Code:

public void registerPlayerConnection(int playerId, byte[] token, byte[] identifier, ClientChannelHandler channelHandler)
	{
		ChatClient chatClient = players.get(playerId);
		log.info("chatservice get player" + playerId);
		if(chatClient != null)
		{
			byte[] regToken = chatClient.getToken();
			log.info("chatservice get token" + playerId);
			if(Arrays.equals(regToken, token))
			{
				chatClient.setIdentifier(identifier);
				chatClient.setChannelHandler(channelHandler);
				channelHandler.sendPacket(new SM_PLAYER_AUTH_RESPONSE());
				channelHandler.setState(State.AUTHED);
				channelHandler.setChatClient(chatClient);
				BroadcastService.getInstance().addClient(chatClient);
				log.info("Player registered from client request " + playerId);
			}
		}
	}

Between Game and Chat servers yes, it is going to be a matter of tweaking one or the other to work properly.
Wish I had not uninstalled NCSoft and kept the 3.5 version. Really don't want to be here patching for hours again he he.

api documentation link:
http://www.mediafire.com/?9p9ekdipwzu4xxd
this is from http://aion-lightning-2.googlecode.com/svn/trunk/doc
but should be useful

Edited 9 PM EST
I've just built u3j-aion build 504 which is up to March 23, 2013. They put in a temporary dropservice.
I'm going to go ahead and test with this and see about submitting some solutions to issues.
I did get the cash shop setup fully versus the 4 wings that come default, among a few other corrections.

I'll work on this one this weekend, but for now just going to play and relax. Have no time until Saturday to truly dig into the communication layer. It is going to be a bit more than just the jar file you mentioned, I don't believe too much more. But I'm tired and want to just relax for the evening.
I'll keep updates here and hope you do likewise whiteone.
Cheers

Still no luck with getting the chat server working really leaning toward the token tho since everything else look's right. Going to keep messing with it till either one pops up that works or i get it to work. :)
