Packet List of Character 7.6

[sequeled]

can someone help me?
I am using the following structure to send the list of characters
for tibia client 7.6 in vb.net, sorry for the bad handling bytes hehehe but follows the code

            '2 bytes packet length
            '1 byte packet type (0x14)
            '2 bytes motd length
            'x bytes motd (id:0-255 + message, example: 123 + "\n\nyaddayadda")
            '0x64 (not sure what this is)
            '1 byte amount of characters
            '--- loop this
            '---2 bytes character name length
            '---x bytes character name
            '---2 bytes server name length
            '---x bytes server name
            '---4 bytes server ip
            '---2 bytes server port

            Dim mtd As String = "123 + \n\nyaddayadda"
            Dim characterName As String = "Duca Nuker"


            Dim PacketSize As Short
            Dim PackType(0) As Byte
            PacketType = BitConverter.GetBytes(Convert.ToInt16(&H14))
            Dim MotdLength As Short = Convert.ToInt16(Encoding.ASCII.GetBytes(mtd).Length)
            Dim Motd As [Byte]() = Encoding.ASCII.GetBytes(mtd)
            Dim CharListType As Short = &H64
            Dim AmmountOfChar As Byte = Convert.ToByte(1)
            Dim charNameLength As Short = Convert.ToInt16(Encoding.ASCII.GetBytes(characterName).Length)
            Dim charName As [Byte]() = Encoding.ASCII.GetBytes(characterName)
            Dim serverNameLength As Short = Convert.ToInt16(Encoding.ASCII.GetBytes(characterName).Length)
            Dim serverName As [Byte]() = Encoding.ASCII.GetBytes(characterName)
            Dim ipServer(3) As Byte
            ipServer = Encoding.ASCII.GetBytes("127.0.0.1")
            Dim portServer As Short = 7171
            Dim premDay As Short = 60

            PacketSize = Len(PacketSize) + Len(PacketType.Length) + Len(MotdLength) + Motd.Length + Len(CharListType) + Len(AmmountOfChar) + Len(charNameLength) + charName.Length + Len(serverNameLength) + serverName.Length + ipServer.Length + Len(portServer) + Len(premDay) 

The structure this done correctly? when I send the package nothing happens on the client tibia 7.6

You need to encrypt the packet with XTEA

[sequeled]

xtea in client 7.6 ? o.0

[Blaster_89]

xtea in client 7.6 ? o.0

I'm fairly sure XTEA was implemented then. I develop mostly for 7.72, and XTEA (and RSA) is implemented there.

Look at the packets with Wireshark

[sequeled]

good idea man ! thanks

[sequeled]

The packet, i'dont understand
someone translate for me the structure for this packet ?

1. you should be looking only at the tcp frame
2. apparently it doesn't use xtea

[sequeled]

yes, but I understand querria What do packet that contains exactly

[Farsa]

1. When does that packet show up? Figure that out

2. Is it reproduceable? Good. Based on when this packet shows up, try to figure what information it carries

3. Try to change the pre-condition for the appearance of this packet. Did the packet data change? Great. Repeat this process a bunch of times until you get several packets of this type with different data. Make sure you keep note of what you did differently each time to make difference in the packet

4. Compare the recorded packets. Try to find how the changed bytes of data correlate to the changes you kept note of.

That's how you figure the packet structure without debugging the client.
