Tool L2Server Admin Socket

[MasterToma]

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
