This put the socket into TIME_WAIT state.

Also check if you are binding to the right ip address (I am assuming it would be localhost) share|improve this answer answered Mar 4 '13 at 10:03 Techmonk 1,001318 It can also be that you are running a web de

"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 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 cli

Do "netstat -a" and look for it... Setting SO_REUSEADDR only lets you bind() if there are no other truly active listening sockets for that port... Typically, the only real use for it is to be able to bind() when there are still TIME_WAIT state sockets bound to that port, from a previous incarnation of the server... But, it won't let two active apps bind() to the same port (on the same IP), if that's what you're trying to do...

Actually i have terminated the program abnormally using ctrl+z. So the socket was not closed. Now if I run the program again it gives bind() failed:address already in use. when i do netstat -a it gives that, that particular socket is connected but not listening. I think i need to do some clean up to close the socket when the program terminated abnormally.. Is there any unix command that kills or closes the socket from command prompt.

Ie: it's still alive, but just 'stopped', and can be restarted again with "bg" or "fg"... So, your app i
