[Development] ModuleFilter

Hello, I've been working with @DevTekVE; and we've completely rewritten his [Only registered and activated users can see links. Click Here To Register...] to make it less goofy.


The new plugin system allows us to write code specific to their modules and packets accuring between them. We still have a lot of work to do, like UI to distinguish between modules and their packets but the current state already allows us to redirect and therefor analyze or filter every connections between any module in one application.

We're aiming to replace the original GatewayServer and AgentServer with custom ones (replaces filter) and the analysis of this data will let us accomplish that in near time. We still don't know the FULL capabilities of the modular injection, but so far we can say that will allow us to modify more of the server behavior without the need of ASM.

We are hoping you contribute to the project as this is a way to start developing a much bigger and stable framework that all of us can us for our servers, for researches and developments. Let's try to give to the Silkroad development community a new focus, and a new purpose.

Here is an example of how the architecture looks like:

nice release :) 2 notes tho, in PluginBase.cs
was useful to me to be able to spoof the NodeType too :D
and as i've noticed, for csro-r files at least :p the AgentServer does not certify against the GameServer, it's the other way around :D any ideas ? did ya try using a multi-agent and multi-game setup ?

Spoofing NodeType was just debug code. I had problems certifying when hosting the ModuleFilter on a dev machine.

Not familiar with CSRO-R but the architecture should be similar if not the same. A mistake your certification would be my first guess.

No, but it should work by adding related services. That's how the structure was planned.

Yet, this application is not usable outside of development scope as dispatched encrypted packets (for example 0x704C - ITEM_USE_REQ) are incorrectly handled by current [Only registered and activated users can see links. Click Here To Register...] implementation. Iwa's [Only registered and activated users can see links. Click Here To Register...] bypasses this problem being a hook instead of a proxy.

sry for the late reply

works perfectly fine, i've just tested it :D tho i have it configured on the same machine ... for ex i have my gameserver on machineid 2 and the shard on machineid 1, the filter will be on machineid 2 so it's spoofin the 1 into 2 :p

i've kinda miss-worded the problem, i didn't mean anything about the actual certification :) i was referring to the server cords :p more specifically the parent - child relation :) and well i've just tested it :D running 2 agentservers and 3 gameservers :p the only configuration that works is having each of the gameservers be child to farm, shard and the 2 agentservers :D and the agentservers be child to farm, shard and the other agentserver :p note it won't work if it's as u have it now (agentserver being child to gameserver not the other way around) if there are more than 1 gameservers or agenservers :D

sadly didn't know that :) and seems u guys have given up on it :p will give it a few more tries myself tho :)

le: got it workin :p most likely ur packet didn't get accepted and u got dc due to not padding it :D

Hi, sorry for bumping this thread, but I get interessted by filter packet between module, I got the idea by reading your post. My main purpose was to spawn monster without any char logged in. We know that the /spawnmonster_all command is run by the Shard which send the information to the GameServer so I decided to sniff packet between them,

Like @[Only registered and activated users can see links. Click Here To Register...] said, it's really fun to handle 0xA003 packet then spoof any port :D

The main problem using this method is:
- All monster spawn with Unique Status
- All monster spawn with the message "[Monster] has appared.."

And you can spawn NPC also, so for making event is pretty nice system without using any bot for TP then spawn ect..

Here: as you can all unique in radar + Npc spawn from the function

Here the packet structure which I sniffed:

SR_GameServer -> SR_ShardManager Service
PING_PACKET
0x7CDC
1 byte uk

SR_ShardManager Service -> SR_GameServer
PONG_PACKET
0xBCDC
empty



+ Bonus spawning 400 NPC

Unintentionally leaking an exploit :lul:

While this tool helps to sniff packets I'd advice against using it for a real server. Insert a new custom module into the server certification architecture and just send your packets to which ever module you want.

I would like to know what are those packets mean if you have a documentation or smth, as i get this randomally which causes shardmanager to crash

The others should be some ShardManager > GameServer packets, which are not public

great project
