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 transport error 202 bind failed address already in use tomcat close() has completed. Because of this, it is possible for the process to complete before transport error 202 bind failed address already in use weblogic the kernel has released the associated network resource, and this port cannot be bound to another process until the kernel has decided that transport error 202 bind failed address already in use jboss 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 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 length of bind failed address already in use faceniff 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 local application dies while a connect

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 messag

After the 1st nc execution , for the remaining of all the lines I am getting below mentioned error message. nc: bind failed: Address already in use nc: bind failed: Address already in address already in use nc: bind failed: Address already in use Is there any way of avoiding this situation? networking tcp netcat share|improve this question edited Dec 9 '14 at 14:48 Eric Leschinski 6991615 asked Mar 24 '14 at 21:27 saurav 1641211 add a comment| 2 Answers 2 active oldest votes up vote 7 down vote accepted Background When you're attempting to use nc in this manner it's continuing to keep the TCP port open, waiting for the destination to acknowledge the receiving of the done request. This is highlighted in the TCP article on Wikipedia. TIME-WAIT (either server or client) represents waiting for enough time to pass to be sure the remote TCP received the acknowledgment of its connection termination request. [According to RFC 793 a connection can stay in TIME-WAIT for a maximum of four minutes known as a MSL (maximum segment lifetime).] You can see the effects of this when I use nc similarly: $ nc -p 8140 -v -n 192.168.1.105 80 Looking at the state of port 8140: $ netstat -anpt | grep 8140 tcp 0 0 192.168.1.3:8140 192.168.1.105:80 TIME_WAIT - In fact on most Linux systems this TIME_WAIT is set to 60 seconds. $ cat /proc/sys/net/ipv4/tcp_fin_timeout 60 If you want to see the effect yourself you can use this snippet to watch when the port becomes released. $ date; nc -p 8140 -v -n 192.168.1.105 80 -w 1; date; \ while netstat -anpt | grep 8140; do date; sleep 10; done; date Tue Mar 25 09:46:59 EDT 2014 Connection to 192.168.1.105 80 port [tcp/*] succeeded!
