Tool L2Server Admin Socket


Recommended Posts

Hi,

 

As you know, there is no separate "Admin" socket for GM. But iv you send packet 00 (Version) with negative values, it will dump some information:

 

import socket
import struct 

port = 7777         # client accepting port
host = '127.0.0.1'  # game server IP

clientsocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
clientsocket.connect((host, port))

# Preparing request
my_bytes = bytearray()
# size
my_bytes.append(7)
my_bytes.append(0)

# packetId
my_bytes.append(0)

# -3
my_bytes.append(253)
my_bytes.append(255)
my_bytes.append(255)
my_bytes.append(255)


clientsocket.sendall(my_bytes)

# Response

unpacker = struct.Struct('h')
size = unpacker.unpack(clientsocket.recv(unpacker.size))[0] - 2
#print "got packet with payload's size: %s" % size

data = clientsocket.recv(size)
#print('Received', repr(data))

# format:                  cdddddS
unpacker = struct.Struct('<bIIIII')


# c        i              i              i          i            i
msgId, npcConnected, maxUsers, usersConnected, usersPlaying, privateStores = unpacker.unpack(data[0:unpacker.size])

str_unpacker = struct.Struct('%ss' % (size - unpacker.size))
stats = str_unpacker.unpack(data[unpacker.size:])[0].decode('utf-16')
                                                                            
print('msgId: %s, npcStatus (2 - Off, 1 - On): %s, maxUsers: %s, usersConnected: %s, usersPlaying: %s, privateStores: %s, stats (free memory, allocated objects, free pool slots, server Up time minutes): %s') % (msgId, npcConnected, maxUsers, usersConnected, usersPlaying, privateStores, stats)

 

And results:

 

Quote

msgId: 0, npcStatus (2 - Off, 1 - On): 2, maxUsers: 1, usersConnected: 0, usersPlaying: 0, privateStores: 0, stats (free memory, allocated objects, free pool slots, server Up time minutes): 2381589,24,2996,57

 

This doesn't work for C4, they changed format a bit. But if you have IDA, you can check yourself
