Python socket error occured
Question: I wrote this code.

    
    
    import socket
    
    host = 'localhost'
    port = 3794
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
    s.bind((host, port))
    while 1:
            print 'Type message you want to send...'
            msg = raw_input()
            if msg == '':
                    s.close()
                    break
        s.sendall(msg)
    

and next execute this code.

    
    
    Traceback (most recent call last):
      File "socket.py", line 11, in ?
        s.bind((host, port))
      File "<string>", line 1, in bind
    socket.error: (99, 'Cannot assign requested address')
    

What's wrong?

Do you know solutions?


Answer: This means that you already have a socket bound to 3794 port.

It may be another application or it means that port didn't got released yet
after the previous run of your own script (it happens, if script terminated
improperly).

Simply try to use another port number - I believe everything will work fine.
