In FTPS, the client connect to the server, the server sending a welcome message; thus, then client send command "AUTH TLS",the server set Certificate、PrivateKey and startServerEncryption; what should the client do to finish this ssl handshake?

Server:

if ("AUTH" == command && "TLS" == commandParameters.toUpper())

 auth();

---

void FtpControlConnection::auth()

 reply("234 Initializing SSL connection.");
 SslServer::setLocalCertificateAndPrivateKey(socket);
 socket->startServerEncryption();

---

void SslServer::setLocalCertificateAndPrivateKey(QSslSocket *socket)

 socket->setPrivateKey(":/ssl/server.key", QSsl::Rsa, QSsl::Pem, "1234");
 Q_ASSERT(!socket->privateKey().isNull());
 socket->setLocalCertificate(":/ssl/server.crt");
 Q_ASSERT(!socket->localCertificate().isNull());

---

void SslServer::incomingConnection(PortableSocketDescriptorType socketDescriptor)

 QSslSocket *socket = new QSslSocket(this);
 if (socket->setSocketDescriptor(socketDescriptor)) 
 addPendingConnection(socket);
 else 
 delete socket;
 

client

socket->connectToHost(hostNameEdit->text(), portBox->value());
socket->write("AUTH TLSrn");
socket->waitForConnected();
socket->startClientEncryption();
socket->waitForEncrypted();

I wish the client finish the ssl shakehand by using startClientEncryption, and then I can use the client socket to send command or file; but it does not work; I know the client socket and the server socket already connect, but how to add ssl on this?
