Hi guys,

I am novice in linux.

I'm trying to access a linux machine.

https://187.84.228.66

But it returns the error message. ERR_CONNECTION_REFUSED

I used the a command to iptables -F and iptables -X. Even so, when I try to access it still gives the same error = ERR_CONNECTION_REFUSED

What can I do?

Thank.

Fernando

Hello team,

I need to urgently terminate a program because it is ending the deadline.

I developed a communication program using peer the following script.js

$(function(){  var messages = [];  var peer_id, name, conn;  var messages_template = Handlebars.compile($('#messages-template').html());  var peer = new Peer({ host: '187.84.228.139', port: 9000, path: '/peerjs', debug: 3, config: {'iceServers': [ { url: 'stun:stun1.l.google.com:19302' }, { url: 'turn:numb.viagenie.ca',  credential: 'muazkh', username: 'webrtc@live.com' } ]}  });  peer.on('open', function(){    $('#id').text(peer.id);  }); })

But at the moment of picking up the id the following messages occur:

Failed to load 187.84.228.139:9000/peerjs/peerjs/id?ts=15204245707800.6806042256269524 resource: net::ERR_TUNNEL_CONNECTION_FAILED
peer.js:1476 PeerJS:  ERROR Error retrieving ID undefined

peer.js:1476 PeerJS:  ERROR Error: Could not get an ID from the server.

peer.js:1476 PeerJS:  ERROR Aborting!
peer.js:1476 PeerJS:  ERROR Error: Could not get an ID from the server.

What is happening? How can I solve this problem?

I strongly urge a solution.

Thanks,

Fernando

Hello Guys,

I have a Java Script program as bellow:

var fs = require('fs'); var PeerServer = require('peer').PeerServer; var server = PeerServer({  port: 9000,  ssl: {    key: fs.readFileSync('/Certificados SSL/chave.key'),    cert: fs.readFileSync('/Certificados SSL/certificado.crt')  } });

When I run the program using node, with the command = node PeerSer.js, occurs the error message:

_tls_common.js:104
     c.context.setKey(options.key, options.passphrase);
               ^

Error: error:0906D066:PEM routines:PEM_read_bio:bad end line
   at Object.createSecureContext (_tls_common.js:104:17)
   at Server (_tls_wrap.js:803:25)
   at new Server (https.js:54:14)
   at Object.createServer (https.js:76:10)
   at PeerServer (C:\Conciliar\node_modules\peer\lib\index.js:76:20)
   at Object.<anonymous> (C:\Conciliar\PeerServer.js:4:14)

   at Object.Module._extensions..js (module.js:654:10)
   at Module.load (module.js:556:32)
   at tryModuleLoad (module.js:499:12)

What is wrong?

Thanks,

Hello Guys.

I'm trying to develop a "video-conference" site.

I'm using PeerJs.

The browsers require that the site page be HTTPS.

The problem is that when calling the PeerJs library, it has an HTTP call and not HTTPS inside.

Then it returns the error:

peer.js: 861 Mixed Content: The page at 'https://conciliar.org/conciliacao_v4.php?' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://0.peerjs.com:9000/tadjksnufvlvj9k9/id?ts=15174003570050.24148370874463132'. This request has been blocked; the content must be served over HTTPS

That is, the PeerJs library itself does not allow the site to be completed, since all calls should be HTTPS, and inside the PeerJs library it calls HTTP.

Has anyone ever had this situation using PeerJs or something similar to solve?

Is there another way to solve this problem?

Thank you,

Fernando

Hi Tim,

the problem is: this video conference is for company. I need to have the videos recorded for later conference. WebRTC allows to interact with HTML and javascript? Can I call the WebRTC from my site?

Hi Guys,

I have a website where I capture the camera image from the user's computer and display it on the site using javascript.

But I need to capture the camera from three different computers and display it on the site at the same time. That is, the three users see each other at the same time on the site. Just like a video conference.

Does anyone have any idea how I can do this?

Thanks,

Fernando

Hi Guys,

I need to develop a website that must capture the camera of the user´s computer and show it on the site in real time. Should be for multiple users, like a video-conference

Is this possible with Javascript?

Thanks.

Hello Guys,

I am runing a program in HTML where I need access Google maps.

But I am receiving the follow error message:

You have included the Google Maps API multiple times on this page. This may cause unexpected errors.

The code is bellow

<head> <?php header('Access-Control-Allow-Origin: *'); ?> <meta name="viewport" content="initial-scale=1.0, user-scalable=no"/> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <link href="http://code.google.com/apis/maps/documentation/javascript/examples/default.css" rel="stylesheet" type="text/css" /> <script async defer src="https://maps.googleapis.com/maps/api/js?key=AIzaSyDLQA97BhcJ6ccP6eAPp0ntUqMepGCoMJ0" type="text/javascript"> </script> <script async defer src="https://www.google.com/jsapi?key=AIzaSyDLQA97BhcJ6ccP6eAPp0ntUqMepGCoMJ0" type="text/javascript"> </script> <script   type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"> </script> <script language="Javascript" type="text/javascript">  //<![CDATA[    google.load("jquery"  , "1.6.2" );    google.load("jqueryui", "1.8.16");  //]]> </script>

How can I fix that error?

Hello Guys,

I have the following problem:

I have a python program where I call a ".bat" file (autentica.bat). This file, in turn, call a java program. Below the codes:

PYTHON

# -*- coding: utf-8 -*- import subprocess import codecs from subprocess import Popen, PIPE, STDOUT def autenticaProg(arquivo):   f = codecs.open("C:\\Nitgen\\arquivo.rec", "wb")   arquivo = arquivo.decode('hex')   f.write(arquivo)   f.close()   p = Popen(["C:\\Zope\\Instance\\2.11.4\\Extensions\\autentica.bat"], stdin=PIPE, stdout=PIPE, stderr=PIPE)   output = p.stdout.read()       return output

".BAT" FILE

java -Djava.library.path="C:\Nitgen" -jar C:\Nitgen\Busca3-N_java.jar C:\Nitgen\arquivo.rec

The return of this program should bring "ok" or "not ok".

But instead of receiving the return "ok" or "not ok", I get the command itself of ".bat" file. That means, the comand in Python "output = p.stdout.read()" is returning "java -Djava.library.path="C:\Nitgen" -jar C:\Nitgen\Busca3-N_java.jar C:\Nitgen\arquivo.rec" and and not the java program's returner that should be returning

Why is this happening? Why is Python returning the command itself in ".bat" and not the return it should be returning by Java?

Thanks,

Fernando

Hello Guys,

I have the following error message when using Ajax in Java:
XMLHttpRequest cannot load http://187.84.232.228:8080/autenticacao/autentica?arquivo=1b54836b092a30a56…    8b7dbbcc2896c1e98b7dbbcc2896c1e98b7dbbcc2896c1e98b7dbbcc2896c1e98b7dbbcc28.    No 'Access-Control-Allow-Origin' header is present on the requested resource.    Origin 'http://www.autbio.com' is therefore not allowed access.
How can I solve this problem?

Thanks,

Hello Guys,

A have the following problem:

I need to access a MySQL 5 database through the PHP language and the Java language.

When access using PHP does not occur any error.

But when accessing using Java, the following error message occurs:

java.sql.SQLException: Access denied for user 'autbio.com'@'187.84.232.228' (using password: YES)

I do not understand the cause of this problem using Java.
