ERROR - RateLimit : close session about araknemu

[vincent4vx]

Hello,
can you enable TRACE logs by changing root level on log4j2.xml :

        <Root level="INFO">
            <AppenderRef ref="STDOUT" level="TRACE"/>
            <AppenderRef ref="errors" level="ERROR" />
        </Root>

to :

        <Root level="TRACE">
            <AppenderRef ref="STDOUT" level="TRACE"/>
            <AppenderRef ref="errors" level="WARN" />
        </Root>

and see exchanged packets ?

Here this is the log after enabled TRACE when I try to connect to the account:

For your issue, this is caused by the spamming of Af packet. This is probably due to invalid SWF redirection : the configuration item C.DELAY_WAIT_QUEUE_REFRESH cannot be loaded from lang_xxx_xx.swf, so il will ask for que position (i.e. Af packet) with an interval of 0 ms.

For the two other messages it's not an issue : it's simply means that netty cannot access to some optimisation because of JVM version or configuration.

Thanks for your answer.
Actually, I'm not really sure of how to configure lang in the client.

After some research, this is what I did:

• I download lang folder in local with this code
• I start a web server to serve the lang folder, I update config.xml file from the client like this:

<conf name="localhost">
  <connserver name="localhost" ip="127.0.0.1" port="4444"/>
  <dataserver url="http://127.0.0.1:9000/dofus/" priority="1" />
  <dataserver url="data/" type="local" priority="0" />
</conf>

• My client load the lang and start, the lang is well loaded. But after few seconds it crash, I think when it's load the news or something like this. So I can't login.
  And if I check my web server logs, files are well loaded without error:

127.0.0.1 - - [01/May/2022 19:03:20] "GET /dofus/lang/versions.swf HTTP/1.1" 200 -
127.0.0.1 - - [01/May/2022 19:03:20] "GET /dofus/lang/versions_en.txt?wtf=0.179472817108035 HTTP/1.1" 200 -
127.0.0.1 - - [01/May/2022 19:03:20] "GET /dofus/lang/swf/lang_en_1077.swf HTTP/1.1" 200 -
127.0.0.1 - - [01/May/2022 19:03:39] "GET /dofus/lang/versions.swf HTTP/1.1" 200 -
127.0.0.1 - - [01/May/2022 19:03:39] "GET /dofus/lang/versions_en.txt?wtf=0.632525463588536 HTTP/1.1" 200 -

I know that is client configuration and, it's maybe out of scope. I will try to find a solution by myself. But if you have any idea, it can be really useful to me.

EDIT:

I found an archive with all lang, I served this files, now it's work! The authentication works well 👍. Following this, I have 2 questions:

• Does that mean we have to launch a web server in parallel, to serve some .swf files (lang files)? If yes, this server is not include in the project?
• Do we have a dataset to insert in database? Even if it's "stupid" data. If it's not the case, I will try to build one.

Thanks.

For your first question, yes it's required to have a server which provide lang files. But you can use official ankama URL if you don't want to run your own web server. But it's totally out of the scope of the game server : it's for client.
For the basic data set I can send you a dump by email if you want.

Ok, I was thinking that is mandatory to run a server in local to serve those files, so in this case that make sense to add some documentation in the project. But i misunderstood. Thanks to take time to solve my issue.

PS: I just send you an email for the dataset, on your gmail address (it's a protonmail address)
