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 the close() has completed. Because of this, it error binding socket (3420) 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 http://stackoverflow.com/questions/15198834/bind-failed-error-address-already-in-use which things happen. Note that if you initiate closure, there is 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 http://hea-www.harvard.edu/~fine/Tech/addrinuse.html is the state that typically ties up the port for several minutes after the process has completed. The 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 t

Try to gess what, among all the ports your app uses, is the one in use. To do so, use lsof if it's available on your system or netstat if it's not. Regards.

Someone is still handling the port. You can either wait for it to clear (a minute or so), or add code to your program allowing it to reuse the port: Code: int tr=1; // kill "Address already in use" error message if (setsockopt(listener,SOL_SOCKET,SO_REUSEADDR,&tr,sizeof(int)) == -1) { perror("setsockopt"); exit(1); } Remove advertisements Sponsored Links Hitori View Public Profile Visit Hitori's homepage!
