A Python 3 script for querying Deus Ex master server info

Postby DxPlayer » Mon Mar 27, 17 4:40 am

Made this just for the sake of curiosity and nostalgia:

Code: Select all
import socket
import sys

# UDP Socket used for communications with each particular Deus Ex game servers
particularQuery = "\\info\\"
sockUDP = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sockUDP.settimeout(1.0)

def queryNormalDeusExServer(ip, port):
    try:
        sockUDP.sendto(bytes(particularQuery,"utf-8"), (ip, port))
        data = sockUDP.recvfrom(2048) # buffer size is 2048 bytes
        print("Received message ::: ", data[0])
    except:
        print("This server did not respond our query ::: ", ip, ":", port)
    return

# TCP/IP socket for communications with the Master Server
sockTCP = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
masterServerAddress = ('master.deusexnetwork.com', 28900)
masterServerAuth = '\\gamename\\deusex\\location\\0\\validate\\FZcjB4YA\\final\\'
masterServerQuery = '\\list\\\\gamename\\deusex\\final\\'


# Communications begin here ---->
print("Connecting to ", str(masterServerAddress), "...")
sockTCP.connect(masterServerAddress)

try:
    # Send TCP auth
    print("Sending authentication ::: ", masterServerAuth)
    sockTCP.sendall(bytes(masterServerAuth,"utf-8"))

    # Receive TCP ACK
    data = sockTCP.recv(1024)
    print("Received ack ::: ", data)

    # Send TCP query
    print("Sending query to master server ::: ", masterServerQuery)
    sockTCP.sendall(bytes(masterServerQuery,"utf-8"))

    # Receive servers Ips and ports by TCP from master server
    data = sockTCP.recv(4096)
    print("Received answer ::: ", data)

    # Master server sends stuff in a big string, each server info separated by \\
    arr = str(data).split('\\\\')

    # For each received server info, UDP queries for infos
    print('Now querying each Deus Ex server .... ')
    for i in arr:
        pos = str(i)
        # Received from master server a bunch of IP:Port
        svr = pos.split(':')
        if len(svr) == 2:
            queryNormalDeusExServer(svr[0],int(svr[1]))
    print("Closing Communication Socket used for normal game servers ...")
    sockUDP.close()

finally:
    print("Closing Communication Socket for Master Server ...")
    sockTCP.close()


This is a Python script that functions like the multiplayer game servers list inside Deus Ex. Queries the master server and lists each known game server and their status.

I used the original client, captured the packages it sent/received to/from the master server and normal game servers (using Wireshark, a network package sniffer) and studied them a little. DeusEx uses TCP for master server communications and UDP for querying each game server individually.

After the master server tells it where are the game servers (master server sends a single string, each game server address:port separated by "\\"), the game client sends a simple query to each server and expects the answer in the format of another simple char array, each information also separated by "\\".

Save this script and run into Python.

Output sample:
Code: Select all
PS C:\Users\eugen> python c:/Users/eugen/Desktop/script.py
>>

The nostalgia <3 The old gamespy protocol still lives on. I will admit though, I was surprised how long GS kept up their MS, good service in my opinion.

Considering it killed dozens of games multiplayers that were still active I think it's appalling what they did, DX was one of many that died following their decision, that I imagine didn't really save that much money.

by gamespy, i meant the original company, not who bought them out (Glu, who did the actual shutdowns are the ones I am not a fan of). The server usage would have been practically nothing for some of the older games too.

Was a shame, though, and even some more modern games were affected. I did email them many a time to try and get them to point master0.gamespy.com to 333 networks when we were testing their MS code back in 2014, fell on deaf ears, as we had seen this as a potential.

I also want to know that server status can now be played on the creeper.
