TERA Server Proxy (Allowing GM commands for specific accounts)
TERA Server Side Proxy for patch 92.03, 92.04 and 100.02

TERA Server Proxy: https://github.com/justkeepquiet/tera-proxy-server

ArbiterServer 100.02 patch: https://disk.yandex.ru/d/A_axHdDfY8A-ng
ArbiterServer 92.03 patch: https://disk.yandex.ru/d/lP9C7mD5zvi-rQ

Network proxy program written on node.js, designed to work on the TERA server side. Based on the Tera Private Toolbox, forked by me with support for modular architecture. In addition to allowing GM (QA) commands, you can install many proxy modules on the side of the server, expanding its functionality, and also fixes some critical server vulnerabilities. There is also support for built-in commands for managing installed proxy modules (it work only in QA mode), you need to use the "~" prefix for input.

UPD: Since the latest versions, the TERA Server Proxy no longer processes packets with the packet integrity algorithm (rehashing packet headers). This should make the program work faster. If necessary, integrity algorithm can be enabled in the config file.

Allowing GM commands for specific accounts

This method is an alternative to the ArbiterHook used in version 92.03.

The implementation allows you to allow GM (QA) commands to certain accounts by proxying connection to the TERA Server with the block of the C_ADMIN packet. It will also need to replace original ArbiterServer.exe to allow QA commands on qaServer disabled mode.

How to install:
1. Unpack the tera-proxy-server to your server directory.
2. Unpack the ArbiterServer_m1.exe to your Bin directory of TERA Server
  (for patch 92.03 you need to use ArbiterServer_m3.exe included in distribution).
3. Open the 1. ArbiterServer.bat file and change ArbiterServer to ArbiterServer_m1
  (or to ArbiterServer_m3 for patch 92.03).
4. Open the DeploymentConfig.xml file, change port 7801 to 7701, and set the qaServer param to false.
5. Start the TERA servers (Arbiter, World, etc.).
6. Run tera-proxy-server\Start.bat.
7. Go to TERA API Admin Panel and set the Privilege value for the account you want to grant commands.
8. Make sure that port 7701 is not available for external user connections.
Privilege values:
- 31 - Only QA commands allowed.
- 32 - Only GM panel allowed (Alt+A).
- 33 - QA commands and GM panel are allowed.
Important note:
Since this method uses proxying, it will no longer be possible to obtain user's real IP address, so IP bans in TERA API will not work. To resolve this problem, update TERA API to the latest version and set parameter API_ARBITER_USE_IP_FROM_LAUNCHER as true. When using the Launcher (Portal API) behind a proxy like nginx or Cloudflare, set parameter LOG_IP_ADDRESSES_FORWARDED_FOR as true.

Does it? I installed it but the server no longer shows up in the client for me to connect, and everything is running.
Did I miss something?

@dziobus The display of the server in server list depends on the API settings. Make sure you have the server enabled and available.

it is, works fine if I do not use the proxy, no issues.
But I noticed there is an error when i launch it saying my Nodejs version is not supported while I did download the latest one from the link you provided.

@dziobus You need to rebuild the libraries for your version of node.js as described in the instructions above.

Without rebuilding, it should work on node v18.4.0 and higher.

I did. So, after installing the latest nodejs I use the cmd command per instruction and get below:

Microsoft Windows [Version 10.0.19042.331]
(c) - WhiteDeath - 2020. All rights reserved.
C:\Users\TeraSV>npm install -g node-gyp
changed 94 packages, and audited 95 packages in 4s
5 packages are looking for funding
run `npm fund` for details
found 0 vulnerabilities

Then when I try to run the build batch file it gives me an error but dissapears immediately. and the Start.bat does not do anything and Tera api broke xD

Had to start from the fresh VM again cause nothing worked after this anymore lol. Not sure what happened or where did i do it wrong. I am using shadows VM if that helps.

Install latest node v18.9.0 and try commands:

Code:

cd your_path_to_tera_server_proxy npm install -g node-gyp npm rebuild

Where your_path_to_tera_server_proxy - specify path to your tera-server-proxy installation.

- - - Updated - - -

If there is a problem with tera-api, delete folder tera-api\node_modules and run install.bat in tera-api folder, then the problem should be solved.

@dziobus Just use node v18.9.0, rebuild is needed only if you have a version below v18.0.0.

Acha....skipping running the build part solves it now it works without issues. Thank you for your help.

No, GM rights are set and meant to be that way that the GM cannot play the game.
Its created like this in Tera.
So if you wanna play and attack you need to only enable QA commands and not the GM panel

i original author for it (asura)
and i notice all of secure issue for this method!

It combines packets with a network protocol and allows you to push a packet with a command after any other=(

I use other code.. but this have problem (stop from unhandled network errors)

I just updated the tera-crypto library for the new version of node.js, no other changes were made.
Thanks for the explanation and the link.

Tera Server Proxy has been updated.

Download: https://github.com/justkeepquiet/tera-proxy-server

Now it is based on TeraToolbox with support for modular architecture.
The fork was made by me, based on the well-known Tera Private Toolbox, which supports patches 92 and 100. There is also support for built-in commands for managing installed proxy modules (it work only in QA mode), you need to use the "~" prefix for input.

Thanks to @sasha5434 (Tera Asura Project) for the information, fake-ping module and provided full opcodes for patch 92.04.

Instructions are not clear enough and leave a lot of room for interpretation:

- What is a "TERA Api" admin panel? There is no such thing. There's steer admin, box admin, server admin.
- Do I unpack the proxy folder itself into my server directory or the contents of the proxy folder? Both can be understood as "unpack the proxy folder in your server directory". Does it even matter?
- How do I know if it is working correctly? Does it output any errors if it's not working correctly?

Clarifying little details like this helps to minimize the troubleshooting needed. The instructions in this thread also miss the step about the ArbiterServer_m1.exe file. That step itself is mentioned on the Github page but the owner of said page has the step false too. The correct location is NOT TeraServers\bin as there is no such thing as a "bin" folder with the 100.02 official release that shadow66 packed up neatly in a virtual machine. The correct location is the root of TeraServers, the folder itself, where ArbiterServer.exe is located. Or at least I assume so. Again, there is a total lack of documentation to confirm this. But the lack of errors from the proxy server's command prompt makes me think that the exe is in the correct location.

- Do I unpack the proxy folder itself into my server directory or the contents of the proxy folder? it doesn't matter while you unpack the files into your server location
- How do I know if it is working correctly? When you start the proxy and an account reach the lobby it prints the output redirection in the cmd window from 7801 to 7701

https://i.ibb.co/z6QCG6c/Screenshot-60.png

The instructions in this thread also miss the step about the ArbiterServer_m1.exe file: I clearly see it

How to install:
2. Open the 1. ArbiterServer.bat file and change ArbiterServer to ArbiterServer_m1.

This guide is really well writen, keep in mind you're speaking about the configuration of the pre-made vm that was maded by someone else

in the original leak (non vm), the server has the following structure

With the patched arbiter, the 92.03 version with proxy is not working propertly...even with 33 as privilege it only allows to use the gm panel but not the gm commands...just does nothing when you type it
28-09-22
hsdn

@argeus99 I think you are using the wrong arbiter file. You need to use ArbiterServer_m3.exe from the leaked server 92.03.
I also confirm that the proxy works fine on server 92.04 (with 300+ players online).

Thanks for clarifying, the structure is indeed different. I suppose the VM creator is to blame because one should never change the folder structure of a release from its original state unless a software error requires that. It only leads to confusion and issues when one guy has a different layout from what's commonly accepted as the original.

I can also confirm that GM commands appear to work on my privilege 31 account. Not all of them though. I could add exp to my character walk speed has no effect in the game. The server proxy prompt however reports the commands correctly:

Quote:

[10984] [12:28:35.608] QA Command Success: add_exp 1
[10984] [12:28:41.389] QA Command Success: invincible
[10984] [12:28:45.521] QA Command Success: invincible on
[10984] [12:28:58.799] QA Command Success: invincible off
[10984] [12:29:12.783] QA Command Success: invincible
[10984] [12:29:17.341] QA Command Success: invincible
[10984] [12:31:41.186] QA Command Success: set_walk_speed 1
[10984] [12:31:44.580] QA Command Success: set_walk_speed 10
[10984] [12:31:48.729] QA Command Success: set_walk_speed 2
[10984] [12:31:57.171] QA Command Success: set_walk_speed
[10984] [12:32:03.237] QA Command Success: set_walk_speed 2

At least setting invincible does work. There's no confirm feedback from the prompt but in the game, I take no damage when hit with the command active.

For move speed try /@speed 2 that will make your character walk faster.

hello, lately this error is appearing and the proxy server crashes, what is the cause?

I think, this problem is due to the fact that vmware incorrectly synchronizes the clock of the virtual machine with the PC, so the task queue in node.js does not work correctly. Check this: https://bootpanic.com/how-to-fix-ass...ine-309-error/
