Program working fine on windows but not running on linux

Adnan hajar

I've been trying to creat a server - client program where the client send a message to the server.

The problem i m having is that when i try to connect to the server on linux it wont connect.
On the other hand if I try to do it on windows it works.

I m not sure if it s a problem with the setting of the computer or it s a part of the code;
please reply with your suggestion of what might be the problem.

attach to this message a useful chunk of code:

void Dialog::on_pushButtonConnect_clicked()
{
    m_pClientsocket->connectToHost(ui->textEditIP->toPlainText(),quint16(ui->textEditPort->toPlainText().toInt()));
    connect (m_pClientsocket,SIGNAL(error(QAbstractSocket::SocketError)),this,SLOT(displayError(QAbstractSocket::SocketError)));
}

Any information about the error itself?

Is the IP local (127.0.0.1) or on another computer. If it is not local maybe you have a firewall problem?

@Rondog in both cases it is not working my client part works if i run the server part on another laptop but the server part is not capable of accepting incoming connection from other laptops

Hi,

Like @Rondog suggested, do you have a firewall blocking incoming connections ? Are you using a reserved port number ?
