macOS: the teacher and student modules are updated to the version 24.3

We are happy to announce today that the teacher and student modules of Net Control 2 Classroom and Professional for macOS are updated to the version 24.3

This version was compiled for better compatibility with macOS 14 (Sonoma), provides compatibility with high resolution displays, includes updated Chat, Whiteboard and other tools and features modified since the version 21.11.

The version is already available in the Downloads section of your customer area account, if your license is within the free maintenance period.

Version 24.0 for Windows

What’s new in the version 24.0

We are happy to announce today that a major update for Net Control ² Classroom, Net Control ² SmallClass and Net Control ² Professional for Windows, the version 24.0 is already available for download.

This update introduces significant changes in the internal structure of the student module, which will provide better compatibility with user mode settings and applications. The update is more focused on improving the usability of existing tools and features, tuning of the user interface details and constructing a base for further products development.

The new version includes the following changes:

Redesigned the Student Console:

Docked and Windowed modes. The Docked (classic) mode shows the console as a docked to the right side of the screen window. In the Windowed mode, the console is shown as a standard window on Desktop, which can be resized, minimized, restored by clicking the taskbar icon and so on. The windowed mode is more adapted for simultaneous work of students with the Student Console and other applications, and provides faster and more flexible access to Net Control 2 Student Console’s features.
Student Console displays information in a smarter way, adapting content to the screen and console dimensions.
Student Console’s blocks are redesigned to be more compact and informative.
New information blocks are available in the Student Console: license information, more detailed lesson information, connection time, detailed system and network information on the About page.

The file collection subsystem has been completely redesigned, allowing students to send files to teachers. Students can send files to teachers just by dragging them onto the Files panel of the Student Console. The classic AutoSend folder is also available.

The feature supports two modes: the simpler send-and-delete mode assumes that files placed to the folder will be sent and subsequently deleted from the folder; and the more sophisticated Keep and Synchronize mode keeps all files on the student computer with providing the necessary versioning.

The student module runs now under a user account, when a user is logged in in the system. This provides better compatibility and interoperability with other user-level applications, system settings and eliminates known restrictions of the system account.

The automatic update subsystem was completely redesigned for more frequent and transparent updates.

This update address also several improvements in the sound subsystem, which is used by different tools in the software, including lesser latency of the captured audio and support of the system audio capture in the Remote Desktop / Control tool.

Net Control 2 for Linux. Classroom Edition

We are proud to announce today a new product in the Net Control ² family of classroom management products – Net Control 2 for Linux.

Net Control 2 for Linux was designed for Debian branch Linux operating systems and adapted for Ubuntu operating systems running 64-bit x86-64 (amd64) architecture processors.

The product is currently only available in the Classroom edition, licensed under the same rules as Net Control 2 Classroom for Windows: with the volume licensing model, you can purchase separate licenses for teacher and student computers; unlimited educational site and organization-wide licenses are available for bulk licensing.

Throughout 2023, Net Control 2 for Linux will be licensed interchangeably with Net Control 2 Classroom Edition, and our customers will be able to use both products under a single Net Control 2 Classroom license for Windows, macOS and Linux in any combination, just preserving the total amount of licensed computers.

All Net Control 2 for Linux licenses purchased during 2023 include three years of free upgrades to any future versions of the software, instead of two years for Net Control 2 Classroom. The main condition here is to purchase a license specifically for Net Control 2 for Linux.

For more information about the product and features, please refer the product home page:

https://netcontrol2.com/linux

While the setup process is quite common for desktop Linux operating systems, we also recommend the Release Notes document, which briefly describes the main installation steps and the nuances of working on the platform:

Remote teaching and Net Control 2

In connection with the outbreak of the COVID-19 epidemic, many organizations and educational institutions are switching to different forms of remote work, teaching and training, and we receive many questions on how to implement and use Net Control 2 classroom management software in the remote education process.

In general, Net Control 2 products are designed and optimized only for use in local networks that offer better performance and low latency than Internet connections offer, lack of web servers for Internet gateways for its work and so on. Therefore, Net Control 2 software can utilize multiple different teaching and monitoring tools at a time without impact on the network resources. On the other hand, specialized remote access software for Internet, implements only a few of features that are available in Net Control 2, but is specially adapted for low speed connections and most often cannot be used without access to Internet.

In addition, the software that is designed for use in Internet must implement and use strong authentication, encryption and data protection mechanisms to prevent unauthorized access to computers in the web. While it is assumed that local networks are already protected from access from outside of the LAN with various software and hardware tools; the software that is designed for use in local networks may use more simple ways of authentication and data protection and concentrate efforts on the better usability and performance. So, Net Control 2 software is not intended for direct use in Internet and cannot connect teachers and students over this network.

However, if you need to organize the remote teaching process and use Net Control 2 software in the process of such training, several approaches are possible.

The purpose of this article is a general description of the possible algorithms. We do not describe each of the cases separately, since the implementation strongly depends on capabilities of the educational institution local network; and in any case the implementation of any of the methods must be done only by a qualified IT specialist who can correctly configure the existing equipment and software. Information provided below is not a step by step guide, it may be incomplete, and please use it on your own risk only.

Students connect existing classroom computers over Internet, using Windows Remote Desktop software. In this case, students work with the classroom computers as if they sit in front of them in the lab. This approach allows using the existing software environment including Net Control 2 software installed in the network. Net Control 2 software supports Windows terminal sessions, and most often, no additional configuration of Net Control 2 software is required. Despite the complexity of some initial configuration (compared to the Case 2), the costs are offset by greater reliability and performance.
This approach usually assumes the following requirements to the network environment of the organization.
- The OS on the classroom computers must support Windows Remote Desktop connection (e.g. for Microsoft Windows, Home editions do not support RDP, and Windows Professional or higher edition should be used).
- As a rule, you will need to set up static IP addresses for computers in the classroom, and configure “port forwarding” on the LAN router for each teacher and student computer (to forward “external” ports to 3389 local port of a concrete teacher or student computer).
- On student and teacher computers you will need to create user accounts with strong passwords and limit remote access by these accounts only .
- For security purposes, we recommend monitoring all incoming connections to the local network of the organization, and to turn off remote access services after end of the work.
In a similar way, remote access to classroom computers can be arranged with third-party software like Zoho Assist, join.me, TeamViewer, etc. To organize the remote access, create remote sessions, obtain IDs and submit them to students, this approach requires presence of a teacher or other specialist in the classroom. After gaining access to the classroom computers, students and teachers can use Net Control 2 software and other resources of the classroom computers for their work.
If you intend to organize a fully virtual classroom in which students and teachers use their personal “home” computers that are connected into a virtual network, you need to install the Net Control 2 software on the teacher and student computers, create a virtual network and configure the software to use resources of this virtual network. To organize a virtual LAN, you can use specialized software like Tunngle (free), LogMeIn Hamachi (free for up to 5 computers). If your organization has a dedicated server or a cloud virtual machine (AWS, Azure), you can install and configure OpenVPN software on the server and create accounts for students and teachers.
In all such cases, the virtual LAN connection provides a virtual IP address that may be used for connecting computers in the virtual LAN. This virtual IP address of the teacher computer should be set in the student module settings of student computers, and the further operation for Net Control 2 software will be the same as in a local network (except the network performance of course).
Using cloud platforms (Amazon AWS, Microsoft Azure and others) you can easily create a virtual Microsoft Windows Server machine in the cloud, set up user accounts on it and install the necessary software, including Net Control 2. Teachers and students can connect then the cloud virtual machine using Windows Remote Desktop, work on it as terminal clients and use software and resources of the server. This method assumes use paid services from cloud providers.

Of course, this article does not describe all possible situations and cases. If you need more information regarding any of the described above methods, please do not hesitate to contact our support team.

Net Control 2 version 20. What’s New.

The specified features concern Windows version of the software only. Availability of features may depend on the software edition.

File Manager

File Manager was redesigned from scratch. More stable and easy to use.

File operations are more predictable due to they are always apply to the currently selected computers (in previous versions File Manager had its own list).

Standard classic NC-style file management: files are displayed in side-by-side panels, in resizable columns, may be selected and managed with standard keyboard shortcuts (like Insert, F2..F10)

Messages

Messages tool. Messages can include special macros in the text to display some computer specific information, like a computer name, connection name, user name, random numbers, split a class to pairs, triples etc.

Polls

Improved user interface for the tool.

Instructor can customize polls using built-in scenarios. Currently included scenarios allow determining users that give the fastest correct replies on a poll.

Whiteboard

Realtime update for the pen tool. Faster response on user computers for other tools.

Other

Help requests: for received help requests, Instructor can initiate a remote desktop session in a click, directly from the help request dialog.

A special button on group icons in the groups list makes possible to wake up student computers of the group in a click.

New numbering of versions. The software versions represent now a year and month of the release, as year.month, e.g. 20.3 is a version released in March 2020.

Version 20 is coming soon!

We expect that a couple of next beta testing cycles in the coming weeks will complete the three-year development period of the new version. The new release introduces numerous improvements in the user interface, new features and multiple upgrades for the existing tools.

For better convenience of handling the software updates, more clear release version numbering, more predictable cycles of free updates, starting with this update, we decided to change the version numbering order.

Version numbers now include a year and month of the release, as also a unique build number. Thus, the next software version is 20.3!

A detailed list of changes will be published shortly.

In conclusion, we would like to remind you that all Net Control 2 SmallClass licenses includes one year, and Net Control 2 Classroom and PRO include two years of free updates to any future versions from the date of purchase. Within this period, all users of versions 11 and 12 will be able to upgrade their software to the version 20.3 at no additional cost.

Mac OS X Catalina and Net Control 2

(Updated) Net Control 2 Classroom and PRO version 20 already support macOS Catalina 10.15

Today, October 8th, 2019 Apple has released the next update for their operating system for desktop platforms Mac OS X 10.15 also known as “Catalina”. Among other great features, this version requires 64 bit support for all applications in the system. Despite Net Control 2 software just does not use large memory volumes and is optimized for the 32 bit model, with Catalina the presence of 64 bit versions of the software in a package is a mandatory requirement.

We are in the process of developing of the next major upgrade for Net Control 2 that will include full support of 64 bits for OS X, but meantime, please note, currently Net Control 2 Classroom and PRO for Mac OS X may not support OS X 10.15 Catalina. The preferred version is OS X 10.13 High Sierra.

Net Control 2 version 12.13

Based on a feedback from our customers, we are introducing with this minor update several improvements for Broadcast Desktop tool to make work with this tool even simpler and effective.

Now an Instructor or User who broadcasts his/her screen to other users, can enable a special Control Mode. When the mode is enabled, all users that are watching the presentation can participate in it and interact with the Instructor’s (or a broadcast source) screen remotely, using a keyboard and mouse.
In addition to the Control Mode, Instructors now can dynamically switch Broadcast Desktop Viewer window on user computers between the full-screen and windowed mode. This may be helpful, for example, for scenarios when a teacher explains some material first and then allows students to make some tasks on their computers not interrupting the broadcast desktop presentation.

This update also includes several other minor improvements and bug fixes.

Net Control 2 version 12.10

Net Control 2 Classroom, SmallClass and PRO for Windows are updated to version 12.10. This update includes several UI improvements and bug fixes in part of work with non-default workspaces; sorting groups in the groups list; significant improvements for the multi display environment and the appearance on a secondary screen.

This version introduces a new engine for automatic updates that should allow more smooth and effective update to newer versions. Beginning from the version 12.10, all minor and build updates will be automatically downloaded and installed, when allowed by the software settings.

Net Control 2 PRO supports setting up a custom domain for Active Directory authentication.

This version includes other bug fixes and minor improvements.
