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?
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);
