WorldSocket::handle_input_header: client sent malformed packet size

[iisdev]

Hi,

I'm sorry to bother you but I'm having trouble finding a definitive answer to this. I'm getting repeating errors every couple of minutes in my logs and I'm not sure what is causing it.

I just did a fresh OS install on my test server, compiled MaNGOS (rev 9999 - no errors) and created the databases restoring only the characters database that we had used previously. We're using UDB (update pack 391). The ports are open correctly and I'm able to connect and play without any problems so far. No disconnects - just this repeating error in the logs.

Also - I haven't announced to anyone that the server is back up; I'm the only one connecting to it right now. The error still happen even after I log out of the game and close the game client.

Is the client that the error states the game client? How is it still repeating even after the game client is closed?

Does anyone know what cmds 1952981076 and -381661184 are?

Thanks in advance!

Perhaps it would be helpful if this message contained the IP address.

-        sLog.outError ("WorldSocket::handle_input_header: client sent malformed packet size = %d , cmd = %d",
-                       header.size, header.cmd);
+        sLog.outError ("WorldSocket::handle_input_header: client '%s' sent malformed packet size = %d , cmd = %d",
+                       GetRemoteAddress().c_str(), header.size, header.cmd);

^Not tested, but should do it.

I think some website function may cause this when the website is accessed and it checks if the server is online.

Thank you very much thanks to your correction I have the address IP which causes this concern: 221.192.199.48

This is usless have any IP address in this case. Error related to client reaction at long disconnected state and later attempt connect to server.

Not mangos problem. Just client wrong data send in described case. Just need close client and start new copy. Ofc, possible another cases of error but this 99% cases of it.

This is not first time answered.

Resolute problem by installing a firewall check. In fact these errors came from attack of robots.

and these attacks of robots all come from China

In fact same error i see at local computer with client and server often But i agree another source fake packets.
