[Solved] Python Error: socket.error [Errno 9] Bad file descriptor

To learn Python Network programming, I wrote two small programs on the server and the client according to the book, and found that an error was reported:

Traceback (most recent call last):

File “./tsTserv.py”, line 20, in

data = tcpCliSock.recv(BUFSIZ)

File “/usr/lib/python2.6/socket.py”, line 165, in _dummy

raise error(EBADF, ‘Bad file descriptor’)

socket.error: [Errno 9] Bad file descriptor

The source code of the server side is as follows:

while True:
        print 'waiting for connection...'
        tcpCliSock,addr = tcpSerSock.accept()
        print '...connected from:',addr
        while True:
                data = tcpCliSock.recv(BUFSIZ)
                if not data:
                        break
                tcpCliSock.send('[%s] %s' %(ctime(),data))
        tcpCliSock.close()
tcpSerSock.close()

Solution:

tcpCliSock.close() is placed in the second while loop, causing tcpCliSock to be closed after receiving data once, and this statement should be placed in the outer loop
