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 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
