Ex.

    uint  1
}
Has a virtual size of 6.

But a physical size of 12.

That means when the client receives the packet it will read the first 6 bytes and then the second half of the first uint will be a new packet to the client and will most likely be read as an invalid size since it obviously isn't the size of a packet.

Instead that packet should have been:
Code:
{
    ushort: 12 (size)
    ushort: 2
    uint: 1
    uint  1
}
---

That's also why I said debug and log the packets. Check what the server is actually sending to the client.

Definitely not a race condition, or at least it shouldn't be since it doesn't send anything across threads to the client during login which is when this happens.

And even when it does it's concurrent and shouldn't cause any race conditions.

Doesn't seem to be.

It’s too difficult for me. can you tell me how to fix it? thank you.

turk55 · 04/26/2019, 18:50

I already did.

Super Aids · 04/26/2019, 19:39

I'd say start by breakpointing the send method and slowly resume after each packet until it disconnects. Then you'll know exactly what packet disconnected you and you'll be able to peek at the data.

I can already tell it looks like something with 10010.

can't find it through breakpoint, this is why I'm here to ask for help.

The problem maybe in the turk55 said checks to the packet reader/writer class.
but I can't find any problems there.

Breakpoint here and check the packets send.

You will be able to see exactly what packet disconnected you.

Check the data sent too and make sure it's not incorrect at any point.

Check send encryption. Maybe if you're not re-creating the packet everytime you send (always sending the same packet), depending on how you're handling encryption, it might be encrypting the packet and if you send it again it will re-encrypt and then make a packet with great size.

It's not an encryption issue since you have no access to the encrypted buffer.

See:

Code:

		/// <summary>
		/// Sends a packet to the client.
		/// </summary>
		/// <param name="packet">The packet to send.</param>
		public void Send(byte[] packet)
		{
			if (Socket == null || packet == null)
			{
				return;
			}
			
			try
			{
				lock (Locks.NetworkLock)
				{
					byte[] pbuffer = packet;
					byte[] buffer = packet;
					
					if (Suffix != null)
					{
						Array.Resize(ref buffer, buffer.Length + Suffix.Length);
						System.Buffer.BlockCopy(Suffix, 0, buffer, buffer.Length - Suffix.Length, Suffix.Length);
						pbuffer = buffer;
					}
					
					if (Cryptography != null)
					{
						buffer = new byte[pbuffer.Length];
						System.Buffer.BlockCopy(pbuffer, 0, buffer, 0, buffer.Length);
						buffer = Cryptography.Encrypt(buffer);
					}
					
					if (Socket.Connected)
					{
						Socket.Send(buffer);
					}
				}
			}
			catch (Exception e)
			{
				#if DEBUG
				#if TRACE
				ErrorLogger.Log(StackTracing.GetCurrentMethod().Name, e);
				#else
				ErrorLogger.Log(Messages.Errors.FATAL_NETWORK_ERROR_TITLE, e);
				#endif
				#else
				Global.Message(e.ToString());
				#endif
				
				Disconnect(Messages.Errors.FATAL_NETWORK_ERROR_TITLE);
			}
		}

Just a guess

I am running into somewhat of a similar issue.

Steps to reproduce:

Open two v5517 conquer clients (make sure you haven't logged in previously, this is important as it doesn't seem to happen otherwise)
Log in two accounts simultaneously
One account will successfully login while the second will disconnect with a "[N-5]The received packet's virtual size is too big." console message

Debugging shows that the disconnection happens after sending the key exchange packet as outlined here

This is strange because it ONLY happens with a newly opened Conquer client where you're logging in for the first time. Any help would be appreciated.

Will look into it at some point as it looks like it might be the key exchange that fails somehow.

Not entirely sure what and why (didn't look into it much.)

I've never come across this issue and many others hasn't either so not sure what's up now.
