socket_bind() unable to bind address
linux, php, webserver, websocket
Solution
I'm guessing the issue is on the Linux server.
Run the `netstat -a -p -n` command under root (e.g. with `sudo`) to understand which process is using that port. Then perhaps do a setsockopt(2) with `SO_REUSEADDR` (see socket(7) for more).
The TCP protocol has some specified delays in minutes (eg keepalive, etc etc...). See e.g. tcp(7)
I do suggest reading a good book on Linux system programming like Advanced Linux Programming and perhaps some material on network programming.
Problem
I'm trying to create a Web Socket Server for a small project I am working on. I have set up the server (located at home) and have port forwarded 80 and 22. I read this tutorial: here And whenever I ssh into my server to run "startDarmon.php" I get the following error: ``` PHP Warning: socket_bind(): unable to bind address [98]: Address already in use in /var/www/server/socket.class.php on line 48 2013-02-23 14:15:38 System: Socket bound to localhost:8000. 2013-02-23 14:15:38 System: Start listening on Socket ``` This is what i think is preventing my client from connecting to the server. So in the startDarmon.php file I have: ``` $WebSocket = new socketWebSocket('MY_IP_NOT_LAN_IP',8000); ``` And inside my client file, I have: ``` var host = "ws://MY_IP_NOT_LAN:8000/server/startDaemon.php"; ``` Does anyone have any suggestions to why this is not allowing me to establish a connection?
