Hi again, I'm creating a chat system with PHP. So I've created the WebSocket server in PHP and the client using the built-in browser WebSocket API. Everything is working fine when I access the client using 'http' & 'ws' protocol, but my problem is when I access the client using 'https' & 'wss', I'm getting the error in firefox saying that: "Firefox can’t establish a connection to the server at wss://192.168.1.201:9000/server.php.". The files are located on https://192.168.1.201/socket/chat2/. Here are the codes: /socket/chat2/server.php: <?php $host = '192.168.1.201'; //host $port = '9000'; //port $null = NULL; //null var //Create TCP/IP sream socket $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); if ($socket === false) { echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) .

Okay, thanks. I hope Krydos sir will do something to allow users to park those domains. In case it takes too long, can you suggest me some other free domain providers (any type of domain would be good, except Freenom). Meanwhile, can you look at my another topic which is still not solved: https://www.helionet.org/index/topic/38541-development-of-an-apache-httpd-handler-module/?fromsearch=1

Okay, here is the domains I've set the nameservers to heliohost. But for FreeDNS I've registered 2 same domain for 2 nameservers as suggested by a user here. Here is a screenshot of the domain list page of freedns: ---freedns.afraid.org--- 1.) sgnetworks.mooo.com 2.) sgads.mooo.com ---nic.eu.org--- 1.) sgads.in.eu.org 2.) sgnetworks.in.eu.org

Okay, but what about https://freedns.afraid.org ? I'm facing the same issue with it too. After being guided by the community here, I've created another record with same domain with "ns2.heliohost.org", but still it's not working.

I don't know, but I've done what I've been instructed to do.

Okay thank you very much.

Okay after trying that, I'm getting the following error in cPanel which is as same as the eu.org:

Okay, let me try this.

I couldn't understand what you are saying. Can you please explain? I don't have any option to add two NS records for a domain in control panel of freedns.afraid.org.

@flazepe, What do you mean by that?

And one more thing, when I'm trying to add the domain in cPanel, I'm getting the following error:

I've already checked that, but there I can set only one Nameserver for a domain so I've set "NS1.HELIOHOST.ORG" and I don't have any options to set both the nameservers.

Okay, I got it, But the problem is, I need two domains if I can't setup eu.org domains then where I can get a new domain, and I don't want to spend money (as the websites will be under testing). I can't even register domains on Freenom because my account is flagged when I forgot to renew a domain and now the domain is declared as "FRAUD". I can use any type of domains whether it's a TLD/ccTLD/gTLD/2nd-level/3rd-level.

Nothing much to explain. Here is the logs showing when setting DNS records in nic.eu.org:

Hello, everyone! I'm going to start a new project which will be a programming language. The structure of the language will be like PHP & Java. It will be built using any one or more than one of the following languages. It will be an open-source application and run either via Console or Apache Module (later via IDE or Runner Application like Java). Anyone who wants to work with me and has knowledge in the following languages can contact me or comment below to discuss how to start and progress. The application will be built using C/C++ (and obviously the Apache Module). We'll start from a simple language by writing a simple Lexer, Tokenizer & Parser for the interpreter then we'll continue to improve the language constantly. If anyone wants to join me can give a reply to this post or send an email at sagnikganguly2012[at]rediffmail[dot]com along with his/her GitHub Username after that he/she can start contributing to the following repository: https://github.com/SGNetworksIndia/SGSP.

Okay, got it. Thank you for helping me out.

Hello Admins, I request you to change the document root of my main domain as I've too many addon-domains it will be better to keep them organized. So kindly give a response telling that if it's possible or not. Because I don't know how the websites are hosted in heliohost but if the websites are configured as VirtualHosts then it might be possible. I know that there are some rules for every request, I don't know if my request complies with the rules of heliohost as I've not seen such a rule there, it's also possible that I might be the first one here who's requesting to change the document root of the main domain.

Hello, I'm going to build a new programming language & interpreter. But for now I've compiled an open-source project named "Pinecone" which is not available for Windows. And built it for Windows and now I want it to be compatible with Apache HTTPD like PHP. So how can I develop a module like PHP for the "Pinecone" interpreter?

I understood what you've said. But the task I've been assigned by an IT company for whom I have given an interview for "Full-stack Web Developer" at first round of the telephonic interview. Now the HR Manager wants me to develop the app for my 2nd round of interview. They have allowed me to use any third-party libraries. But I'm not comfortable with any third-party libraries, that's why I've asked for without any framework or libraries.

Hi, I wat to build a scalable web app for login/register API in PHP without using any third-party frameworks or libraries as well as the API URLs for the app will be as follows: Signup URL: /user/signup Signin URL: /user/signin Profile URL: /user/profile Update profile URL: /user/profile/update After login/register the app should generate and return the access token which is required to access profile. How can I do it?

I have the following class: SGNBEResponseCode class: <?php namespace SGNBackend\SGNBEResponseCodes; class SGNBEResponseCode { public function __construct(){ print_r(__CLASS__); return __CLASS__; } } ?> <?php namespace SGNBackend\SGNBEResponseCodes; class Common extends SGNBEResponseCode { public const UNKNOWN_ERROR = -1; public const INVALID_REQUEST = 0; public const REQ_FAILED = 100; public const DB_QUERY_ERROR = 101; public const DB_COUNT_ERROR = 102; public const DB_FETCH_ERROR = 103; public const EMPTY_PARAM_VALUE = 104; public const INVALID_PARAM_VALUE = 105; public const REQ_DONE = 106; public function __construct(){ print_r(__CLASS__); return __CLASS__; } } ?> Here SGNBEResponse class: <?php namespace SGNBackend; class SGNBEResponse{ const response = array("error"=>true, "code"=>-1, "name"=>"UNKNOWN_ERROR", "message"=>"An unknown error has occurred"); public static function generateErrorFromCode(SGNBEResponseCode $code, string $args = null){ $c = debug_backtrace(); print_r($c); //return "test"; } } ?> And I'm trying to access the constants like this: <?php $sgnbe = new \SGNBackend\SGNBEResponse(); print_r(\SGNBackend\SGNBEResponse::generateErrorFromCode(\SGNBackend\SGNBEResponseCodes\Common::INVALID_REQUEST)); ?> And when I access the constants an instance of the class along with the name of the constant and value should be returned instead of the value of the constants. Can I do it? If yes then how?

Thank you so much!

Okay thanks! Let me try this.

Yes obviously, You can never add a domain without pointing it to the nameservers of HelioHost even you'll never be able to see this type of errors in cpanel. I think it's a cache related issue.

Okay, I'll change the name but to change the name I've to change lot of things. For now I just need to check if everything is working fine.
