Hello,

     Am trying to write a program using crypt library, which can connect to
ssh server and execute commands remotely.

     I was successful in creating ssh session and writing data to the
session. But, i couldnt able to read data from the session.

     Below is the code which i used for creating, writing and reading
output back from ssh session.

     Please let me know your thoughts and correct me.

    cryptInit();

    CRYPT_SESSION cryptSession;


    int bytesCopied, status;

    /* Create a client session */

    status = cryptCreateSession( &cryptSession, CRYPT_UNUSED /* CRYPT_UNUSED */,

    CRYPT_SESSION_SSH );

    if( cryptStatusError( status ) )

    {

        qDebug() << "Couldnt able to create session";

    }


    /* Set servername and password to the session */

    const char c_username[30] = "ssh://[email protected]";

    const char c_password[10] = "xx";

    status = cryptSetAttributeString( cryptSession, CRYPT_SESSINFO_SERVER_NAME,

    c_username, strlen(c_username) );

    if( cryptStatusError( status ) )

    {

        cryptDestroySession( cryptSession );

        qDebug() << "Couldnt able to input servername to the session";

    }

    status = cryptSetAttributeString( cryptSession, CRYPT_SESSINFO_PASSWORD,

    c_password, strlen(c_password) );

    if( cryptStatusError( status ) )

    {

        cryptDestroySession( cryptSession );

        qDebug() << "Couldnt able to input password to the session";

    }

    else

    {

        qDebug() << "Success";

    }


    /* Activate the session */

    status = cryptSetAttribute( cryptSession, CRYPT_SESSINFO_ACTIVE, TRUE );

    if( cryptStatusError( status ) )

    {

        cryptDestroySession( cryptSession );

        if ( status = CRYPT_ERROR_WRONGKEY)

            qDebug() << "Couldnt able to activate session" << status;

    }

    else

    {

        qDebug() << "Session activated";

    }


    /* Send a command to the remote system */

    char command[30] = "ls -l\r\n";

    status = cryptPushData( cryptSession, command, strlen( command ),
&bytesCopied );

    if( cryptStatusOK( status ) )

    {

        if( bytesCopied != ( int ) strlen( command ) )

            status = -1; /* Not all data was processed */

        else

        {

            status = cryptFlushData( cryptSession );

            qDebug() << "Flushed Data"<< status;

        }

    }



    /* Read back the response */

    int *outDataLength = 0, outDataMaxLength = 500;

    char outData[499];


    status = cryptPopData( cryptSession, outData, outDataMaxLength,
outDataLength );

    if( cryptStatusError( status ) )

    {

        cryptDestroySession( cryptSession );

        qDebug() << "Error Reading data" << status;

    }


    //cryptDestroySession( cryptSession );

    qDebug() << "Return Value:"<<outData;

    qDebug() << "Bytes Copied:"<<*outDataLength;


    cryptDestroySession( cryptSession );

    cryptEnd();
