Bind Address Already In Use Ssh
socket() returns success and hence forth bind() and listen(), accept() and hence recv() - All fine till here. 2nd instance throw error while binding "Address already in use" I went through all the post earlier on this and i dont see any specific solution provided on the same. My code is as below :- if((status = getaddrinfo(NULL,"8080",&hints,&servinfo))!=0){ ALOGE("Socket:: getaddrinfo failed %s\n",strerror(errno)); return NULL; } server_sockfd = socket(servinfo->ai_family, servinfo->ai_socktype, servinfo->ai_protocol); if(server_sockfd == -1) { ALOGE("Socket:: Scoket System Call failed %s\n",strerror(errno)); return NULL; } if ((setsockopt(server_sockfd, SOL_SOCKET, SO_REUSEADDR, &opt, sizeof(int))) < 0) { ALOGE("Socket:: setsockopt failed %s\n",strerror(errno)); return NULL; } ret = bind(server_sockfd, servinfo->ai_addr,servinfo->ai_addrlen); if(ret!=0) { ALOGE("Socket:: Error Binding on socket %s\n",strerror(errno)); return NULL; } This code runs on android platform. I have properly closed each session before opening a new session as below :- ret = shutdown(client_sockfd,0); if(ret != 0) ALOGE("Socket:: Shutdown Called%s\n",strerror(errno)); I tried with close as well b

"bind: Address already in use" Dear friends, I'm very new to Ubuntu and not very firm address already in 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 above syntax? If yes how would the syntax

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, i
