Bind Address Already Use Error

and both ends must ACK (acknowledge) each other's FIN packets. The FIN packets are initiated by the application performing a close(), a bind address already in use ssh shutdown(), or an exit(). The ACKs are handled by the kernel after the address already in use linux 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 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 bind: address already in use docker 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, the local end will have to initi

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 http://stackoverflow.com/questions/5106674/error-address-already-in-use-while-binding-socket-with-address-but-the-port-num 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 Creation: Success File open: Success Socket Bind: Address already in use Socket Listen: Address already in use ^C anirudh@anirudh-Aspire-5920:~/Desktop/testing$ c linux sockets share|improve this question edited Dec 18 '15 at 20:40 iharob 39.3k42851 asked Feb 24 '11 at 15:25 Durin 68731227 add a comment| 5 Answers 5 active oldest votes up vote 34 down vote accepted I've run into that same issue as well.

"bind: Address already in use" Dear friends, I'm very new to Ubuntu and not very firm with the terminal syntax and system settings yet. I hope someone can advice me on two issues regarding SSH and the secure use of scripts in the terminal. So yesterday I sucessfully set up a ssh tunnel with PuTTY SSH Client defining Source Pourt and Destination under -> SSH ->Tunnels. And today I tried to do the same but using the build-in SSH client in the terminal. I entered the following syntax: ssh -f -L 5432:localhost:5433 someAccountname@someIPaddress sleep 10 I was prompted to enter a password. After entering the password the following error message appeared: "bind: Address already in use" So I guessed that PuTTY was still using the local port. After deinstalling PuTTY the same errormessage came up and after reinstalling PuTTY all configuration was still there. So I guess that PuTTY somehow changes a config file that controls sistemwide port-uses. So first:Is th
