Message:

I would like to create a chat server placed on my Nas Synology DS212J accessible by internet. I am not very competent in the field but I understood that it was necessary to use "websocket". I tried with Node.js but my nas does not allow me to install a fairly recent Node version apparently. So I am looking at "PHP Websocket".
I managed to find a code on: https: //github.com/Flynsarmy/PHPWebSocket-Chat which I deposited in the / web / chatLogPat folder of my Nas.
I managed to launch server.php in SSH but when I connect to my Chat page, I cannot establish a connection ... Putty (ssh) tells me all the time: "myconnectionIp has disconnected"

Can you help me please?

Thanks a lot !!!

my link to index.html is: https://serveurarchaux.synology.me/chatLogPat

My NAS is connected to my box in: 192.168.1.12

Here are my files:

server.php on web/chatLogPat

    <?php

// prevent the server from timing out

set_time_limit(0);



// include the web sockets server script (the server is started at the far bottom of this file)

require 'class.PHPWebSocket.php';



// when a client sends data to the server

function wsOnMessage($clientID, $message, $messageLength, $binary) {

    global $Server;

    $ip = long2ip( $Server->wsClients[$clientID][6] );



    // check if message length is 0

    if ($messageLength == 0) {

        $Server->wsClose($clientID);

        return;

    }



    //The speaker is the only person in the room. Don't let them feel lonely.

    if ( sizeof($Server->wsClients) == 1 )

        $Server->wsSend($clientID, "There isn't anyone else in the room, but I'll still listen to you. --Your Trusty Server");

    else

        //Send the message to everyone but the person who said it

        foreach ( $Server->wsClients as $id => $client )

            if ( $id != $clientID )

                $Server->wsSend($id, "Visitor $clientID ($ip) said \"$message\"");

}



// when a client connects

function wsOnOpen($clientID)

{

    global $Server;

    $ip = long2ip( $Server->wsClients[$clientID][6] );



    $Server->log( "$ip ($clientID) has connected." );



    //Send a join notice to everyone but the person who joined

    foreach ( $Server->wsClients as $id => $client )

        if ( $id != $clientID )

            $Server->wsSend($id, "Visitor $clientID ($ip) has joined the room.");

}



// when a client closes or lost connection

function wsOnClose($clientID, $status) {

    global $Server;

    $ip = long2ip( $Server->wsClients[$clientID][6] );



    $Server->log( "$ip ($clientID) has disconnected." );



    //Send a user left notice to everyone in the room

    foreach ( $Server->wsClients as $id => $client )

        $Server->wsSend($id, "Visitor $clientID ($ip) has left the room.");

}



// start the server

$Server = new PHPWebSocket();

$Server->bind('message', 'wsOnMessage');

$Server->bind('open', 'wsOnOpen');

$Server->bind('close', 'wsOnClose');

// for other computers to connect, you will probably need to change this to your LAN IP or external IP,

// alternatively use: gethostbyaddr(gethostbyname($_SERVER['SERVER_NAME']))

$Server->wsStartServer('192.168.1.12', 9300);

My question is : What should I put as host on the server.php and index.php ?
I tried "localhost", the server seems to connect but index.php seems to not connect...
I really need help !!! Pleaaaase !!

My Answer:
PHP and Websockets to achieve this. Can someone guide me on how to set this up on my Synology NAS? Thank you.
