New submission from George,Y:
I need to know the IP address on the other side of a broken TCP/IP connection.
"socket.getpeername()" fails to do the job sometimes because the connection has
been closed, and Windows Error 10038 tells the connection is no longer a socket
so that the method getpeername is wrongly used.
Here goes the code in main thread:
mailbox = queue.Queue()
read_sockets, write_sockets, error_sockets =
for sock in read_sockets:
mailbox.put( (("sock_err",sock), 'localhost') )
The sub thread get this message from mailbox and try to analyze the broken
socket, to simplify I put the code and output together:
<socket.socket [closed] fd=-1, family=AFNET, type=SOCKSTREAM, proto=0>
OS.Error[WinError10038]an operation was attempted on something that is not a
Surprisingly, this kind of error happen occasionally - sometimes the socket
object is normal and getpeername() works fine.
So once a connection is broken, there is no way to tell the address to whom it
