尝试以symfony中的访问权限禁止的方式访问套接字

Question

Hello I'm newbie for symfony frame work.

currently using Symfony version 3.4.

I'm implementing websockets to my project using Gos Web Socket Bundle (https://github.com/GeniusesOfSymfony/WebSocketBundle) and documentation also.

after run this command

`php bin/console gos:websocket:server`

getting message like this.

`Failed to listen on "tcp://127.0.0.1:8080": An attempt was made to access a socket in a way forbidden by its access
   permissions.`

in config.yml added this

`# Web Socket Configuration
gos_web_socket:
    server:
        port: 8080        #The port the socket server will listen on
        host: 127.0.0.1   #The host ip to bind to`

If I changed port no 8080 to 80 I will get any error from command prompt but in browser it doesn't work. If I used 8080 websocket server is not running. Help me out! spent whole full day on this.

Without being a root (or via sudo) you are not allowed to listen to privileged ports (<1024).

As for the port 8080 check if there is another service already running on it:

lsof -i :8080

Have you tried selecting another port, for example, 8888?

Hope this helps...
