Bind Failed Address Already In Use Iperf
vote favorite 10 I have a question regarding client socket on TCP/IP network. Let's say I use try: comSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) comSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) except socket.error, msg: sys.stderr.write("[ERROR] %s\n" % msg[1]) sys.exit(1) try: comSocket.bind(('', 5555)) comSocket.connect() except socket.error, msg: sys.stderr.write("[ERROR] %s\n" % msg[1]) sys.exit(2) The socket created will be bound to port 5555. The problem is that after ending the connection comSocket.shutdown(1) comSocket.close() Using wireshark, I see bind address already in use ssh the socket closed with FIN,ACK and ACK from both sides, I can't use the port again. I get the following error: [ERROR] Address already in use I wonder how can I clear the port right away so that next time I still can use that same port. comSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) setsockopt doesn't seem to be able to resolve the problem Thank you! python sockets tcp port share|improve this question edited Dec 31 '13 at 19:49 asked Jun 17 '11 at 0:12 Tu Hoang 95372235 Why does a client need a specific port? –AJ. Jun 17 '11 at 0:17 Because I have to put that into a production server, and in that server, all outgoing connections are blocked. I need to specify a specific port to the socket so that they can set up a rule on the firewalls that allows the connection to go through. –Tu Hoang Jun 17 '11 at 0:46 I suggest you copy & paste the actual code. What you wrote above has an obvious error that would prevent you from seeing the behavior you claim to have seen. This leaves readers with no idea what else you have neglected to tell us that
and both ends must ACK (acknowledge) each other's FIN packets. The FIN packets are initiated by the application performing a close(), a shutdown(), or an exit(). The ACKs are handled by the kernel after python socketserver reuse address the close() has completed. Because of this, it is possible for the process to complete

before the kernel has released the associated network resource, and this port cannot be bound to another process until the kernel has decided

that it is done. Figure 1 Figure 1 shows all of the possible states that can occur during a normal closure, depending on the order in which things happen. Note that if you initiate closure, there is http://stackoverflow.com/questions/6380057/python-binding-socket-address-already-in-use a TIME_WAIT state that is absent from the other side. This TIME_WAIT is necessary in case the ACK you sent wasn't received, or in case spurious packets show up for other reasons. I'm really not sure why this state isn't necessary on the other side, when the remote end initiates closure, but this is definitely the case. TIME_WAIT is the state that typically ties up the port for several minutes after the process has completed. The http://hea-www.harvard.edu/~fine/Tech/addrinuse.html length of the associated timeout varies on different operating systems, and may be dynamic on some operating systems, however typical values are in the range of one to four minutes. If both ends send a FIN before either end receives it, both ends will have to go through TIME_WAIT. Normal Closure of Listen Sockets A socket which is listening for connections can be closed immediately if there are no connections pending, and the state proceeds directly to CLOSED. If connections are pending however, FIN_WAIT_1 is entered, and a TIME_WAIT is inevitable. Note that it is impossible to completely guarantee a clean closure here. While you can check the connections using a select() call before closure, a tiny but real possibility exists that a connection could arrive after the select() but before the close(). Abnormal Closure If the remote application dies unexpectedly while the connection is established, the local end will have to initiate closure. In this case TIME_WAIT is unavoidable. If the remote end disappears due to a network failure, or the remote machine reboots (both are rare), the local port will be tied up until each state times out. Worse, some older operating systems do not implement a timeout for FIN_WAIT_2, and it is possible to get stuck there forever, in which case restarting your server could require a reboot. If the loc
