It worked and did the job for me. At the end of the code I close bind failed address already in use iperf 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.

"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 https://ubuntuforums.org/showthread.php?t=2175004 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 above syntax? If yes how would the syntax look like and how can I safely secure the script from thirdparties? Ithought of maybe encrypting all scripts that contain password information with a master password. Like this I would not need to remember all login-information for

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 is still alive and holding the socket open... If your app truly terminated, then the OS would've closed the socket for you automatically... Is there any unix command that kills or closes the socket from command prompt. Well, it doesn't make sense to talk about killing a socket... You can kill the app that has the socket open, however... Just use "kill" or "killall" or whatever... Doing that will close the socket...
