It worked and did the job for me. At the end of the code I close the socket as well. The very next instant I run my code again and bind address already in use ssh it shows me that the address is already in use. I have printed the meaning of error values strerror(errno); to see if my code working properly at each point. To check if the port is free I checked it using netstat but it shows that port number 8000 is free. It has happened with me a lot of times. Every time I then wait for a few more secs and then it starts working again. I am using c language. So what is he reason for this behavior by my OS. After a few more secs I run the code and then it works. anirudh@anirudh-Aspire-5920:~/Desktop/testing$ sudo ./a.out Socket Creation: Success File open: Success Socket Bind: Address already in use Socket Listen: Address already in use ^C anirudh@anirudh-Aspire-5920:~/Desktop/testing$ sudo netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1348/lighttpd tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 984/sshd tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN 1131/cupsd tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 1211/mysqld tcp6 0 0 :::22 :::* LISTEN 984/sshd tcp6 0 0 ::1:631 :::* LISTEN 1131/cupsd anirudh@anirudh-Aspire-5920:~/Desktop/testing$ sudo ./a.out Socket Cre

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 http://stackoverflow.com/questions/5106674/error-address-already-in-use-while-binding-socket-with-address-but-the-port-num 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 http://hea-www.harvard.edu/~fine/Tech/addrinuse.html 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 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,
