Accommodation of sockets on BB10 (server) does not work. Advice?

I saw a server FTP application in the app store, so I tried it. It hosts an open port that I can connect to with my FTP client, which is great. However, when my own application (which is an application of indigenous waterfalls) try to host an open port, I can't connect to it. I get a "connection refused" on the client. During my connection attempts, my request (which was accepting connections and being debugged) do not unlock the State listen to because it never received the connection. This situation is evident, even I'm debugging or just run the application launch manually.

I can only conclude that there is a firewall any on the device that blocks incoming connections (and so, accommodation sockets). Or routing Sockets open is disabled somehow.

My question is: why android applications are allowed to host a srever socket while the applications of stunts are not? And above all, y at - it a solution?

EDIT: I enabled permission to acccess_internet.

Hello

I just created a test project and I can confirm that QTcpServer works using WiFi on Dev Alpha A:

Newspapers of the device:

15:58:04.371 may 08 server started

15:58:55.953 may 08 new connection

$ telnet 192.168.0.33 5335
192.168.0.33 by train...
Connected to 192.168.0.33.
[Escape character is ' ^]'.

This part of the code is not necessary. It blocks the event loop and the slot is not called:

while ( _server.isListening() ) // Server constantly waits
    {
        // If a new connection is available, onNewConnection() will be triggered
        _server.waitForNewConnection( -1 );
    }

Here is my code:

TestProj.hpp

#ifndef TestProj_HPP_
#define TestProj_HPP_

#include 
#include 

namespace bb { namespace cascades { class Application; }}

class TestProj : public QObject
{
    Q_OBJECT
public:
    TestProj(bb::cascades::Application *app);
    virtual ~TestProj() {}

protected slots:
    void onNewConnection();

protected:
    QTcpServer *tcpServer_;
};

#endif /* TestProj_HPP_ */

TestProj.cpp:

#include "TestProj.hpp"

#include 
#include 
#include 

using namespace bb::cascades;

TestProj::TestProj(bb::cascades::Application *app)
: QObject(app)
{
    QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);

    AbstractPane *root = qml->createRootObject();
    app->setScene(root);

    tcpServer_ = new QTcpServer(this);
    QObject::connect(tcpServer_, SIGNAL(newConnection()), this, SLOT(onNewConnection()));

    if (!tcpServer_->listen(QHostAddress::Any, 5335))
    {
        qDebug() << "Unable to start the server:" << tcpServer_->errorString();
    }
    else
    {
        qDebug() << "Server started";
    }
}

void TestProj::onNewConnection()
{
    qDebug() << "New connection";
}

  • VMWare Update Manager Server does not work after changing name of host/IP

    I have Virtual Center 2.5 update 4 and Manager Update on two separate servers.

    I had to rename and change the IP of the Server Manager to update, and now the Server Update Manager does not work.

    Here are two mistakes that I get, when you try to activate the plugin Update Manager:

    "The server took too long to respond" or "VMWare Update manager cannot accept applications because VirtualCenter.

    Server is not reachable, or it's the database is not reachable

    by train to stop'

    That's what I did to change the host name:

    -J' uninstalled virtual UpdateManager 1.0 Clients Center customer.

    -I stopped the Service VMware Update Manager on the update server

    -J' I renamed the update server changed its IP address and the host name and then rebooted the server (without starting the VMware Update Manager Service)

    -J' changed the value of the fields

    dbo. VPX_EXT_CLIENT. URL

    dbo. VPX_EXT_SERVER.UR

    -in the vCenter (on the vCenter server) database reflecting the new name of the server (the new hostnameis to pings to the vCenter server)

    -J' restarted the vCenter Server

    -J' started the Service VMware Update Manager on the update server

    -J' installed the client plugin update manager Virtual Infrastructure client

    -J' have TRIED to activate the plugin, but I got a warning about an untrusted certificate (I guess it happened also when I installed the client for the first time, and everything worked) and then I got two errors:

    sometimes "the server has taken too much time to react" and a few other times "the VMWare Update manager cannot accept applications because VirtualCenter.

    Server is not reachable, or it's the database is not reachable

    by train to stop'

    I think that there are a few other references to the host name of the Update Manager, which I have not changed, on the vCenter server or Manager Update server...

    Does anyone have an idea what do I do?

    Thank you in advance.

    I would try just reinstalling the update on existing installation manager.  Do not overwrite the database in the process so that you shouldn't really lose anything.  Not the plugin, but since the Update Manager vCenter installation media.

    Give that a try and let us know how it goes.

  • The virtual DHCP server does not work why?

    Hello

    I used the workstation to create a virtual machine with NAT connection. The virtual machine works well in my computer with WiFi, and it can get an IP address from the virtual DHCP server successfully. Then I copied it on another computer with no network connection (no wifi, no cable connection). After startup, the virtual machine cannot obtain an IP address from the DHCP server. In my opinion, if she has a physical or network connection, the DHCP server should work anywhere. I wonder why the server may not work.

    Also, is there any document to introduce inside the vmware network. Thank you!

    Yes, NAT is the network setting that allow you to generate ip which is pre defined in the virtual network Editor. and your virtual machine will also communicate to the outside network.

    On the contrary if you change host Only.The vm will get the ip address range but they will communicate within your host not the outside world. If no internet connection then. (No network connectivity don't require in this case)

  • Why my cron for primary/secondary server does not work, but worked at the prompt of

    Any help guru?

    Hello;

    Usually it is a question of the environment.

    The script works in command prompt, because when you signed on your chosen username environment of a profile settings, for example .bash_profile.

    A crontab task presents no environment. That's why you call hydev_env at the beginning of the script. If something things are missing in your env file especially likely.

    What I do is keep a file for each database in the environment to a place like this:

    / u01/app/Oracle/dba_tool/env (/ u01/app/oracle/dba_tool/env/PRIMARY.env)

    The PRIMARY.env file is .env

    What I keep in there, that's all I need a job like crontab background would need:

    ORACLE_BASE=/u01/app/oracle

ULIMIT=unlimited

ORACLE_SID=PRIMARY

ORACLE_HOME=$ORACLE_BASE/product/11.2.0.2

ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

LIBPATH=$LD_LIBRARY_PATH:/usr/lib

TNS_ADMIN=$ORACLE_HOME/network/admin

PATH=$ORACLE_HOME/bin:$ORACLE_BASE/dba_tool/bin:/bin:/usr/bin:/usr/ccs/bin:/etc:/usr/sbin:/usr/ucb:$HOME/bin:/usr/bin/X11:/sbin:/usr/lbin:/GNU/bin/make:/u01/app/oracle/dba_tool/bin:/home/oracle/utils/SCRIPTS:/usr/local/bin:.

export TERM=vt100

export ORACLE_BASE ORACLE_SID ORACLE_TERM ULIMIT

export ORACLE_HOME

export LIBPATH LD_LIBRARY_PATH ORA_NLS33

export TNS_ADMIN

export PATH

export MAILTO=

    Important If you are not sure, a setting on your system type "env" at a Linux prompt, when you are logged in as user where the script works. Change as needed in your file .env.

    I have here a script call in crontab to check the tablespaces

    #!/bin/bash
####################################################################
#

if [ "$1" ]
then DBNAME=$1
else
echo "basename $0 : Syntax error : use . quickcheck  "
exit 1
fi

#
# Set the Environmental variable for the instance
#
. /u01/app/oracle/dba_tool/env/${DBNAME}.env
#
#

$ORACLE_HOME/bin/sqlplus /nolog <

    Note how I passes the name of the comic as a parameter to the script if I can use the script with several database without changing.

  • My password for the integrated on my HP OfficeJet 8100 Web server does not work

    I entered my password, and kept the username by default (admin), but now I can't access the pages of EWS (locked).  How can I reset EWS (or the full printer) to the factory settings?

    Maybe my password is too long?  (20 characters)

    Thank you!

    Hello

    Please, make sure that you type the user as administrator when you type the password, then check to see if that can help you.

    If the same persists, reset the network settings, which will also reset the administrator password:

    If necessary, print a Network Setup page to find the IP address if it has changed, which can be done by pressing a second time the summary and the button wireless on the printer control panel.
