I choose different ports... Thanks for the help .. Thanks all. –TamiL Mar 4 '13 at 10:18 1 I faced the same issue when I closed the server program with client program still running. This put the socket into TIME_WAIT state. Here's an elaborate discussion of the problem: How to forcibly close a socket in TIME_WAIT? –Narendra Apr 5 at 6:10 add a comment| 4 Answers 4 active oldest votes up vote 12 down vote accepted The error usually means that the port you
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 bind failed address already in use iperf after the 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 address already in use socket 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, http://stackoverflow.com/questions/15198834/bind-failed-error-address-already-in-use 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 http://hea-www.harvard.edu/~fine/Tech/addrinuse.html 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 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 cou

"bind: Address already in use" Dear friends, I'm very new to Ubuntu address already in 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 this right and can I change that file in order to be abled to use the terminal client? And second: I would like to use the terminal client since this enables me to write a script and avoid annoying clicking and providing logincredentials every time I want to connect to the server. So is there a way to safely store the password within a script with the ab
