U Merzheviy OS you can see a few parts:
- features of managing local WS resources – functions for distributing RAM between processes, scheduling and dispatching processes, managing processors in multiprocessor machines, managing peripheral devices and other functions for managing local OS resources;
- Features of the provision of power resources and services in the dormitory - Server part of the OS (server). These are ways to ensure, for example, blocking of files and records, which is necessary for your personal blog; entering the names of border resources; processing requests for remote access to the local file system and database; bathing with cups of water from distant cores to their peripheral devices;
- How to request access to distant resources and services - Client part of the OS (redirector). This part consists of recognition and redirection of requests to remote resources from programs and users. In this case, you are asked to enter the program in a local form, and it is transferred to the next form in another form, which corresponds to the capabilities of the server. The client part also accepts input from servers and converts them into a local format, so that the input of local and remote inputs is not affected;
- communication features of health care, For any assistance, an exchange of information is required. This part ensures addressing and buffering of notifications, selection of transmission routes, reliability of transmission, etc. є special information about transportation.
Remote PC cleaning programs are well known to any system administrator or technical support worker, as part of their daily activities, the smell gradually fades away from the admin tasks. construction of servers and PCs of local users. The most advanced utility for remote PC management is, of course, Remote Desktop Connection, which is included with the Windows operating system. This fact is explained not so much by functional possibilities as by the fact that it is a stock OS, and it is not strictly necessary to download it. Although the functionality of this utility is lacking, in practice it is insufficient, so specialized software packages from third-party vendors are often used. In this article we will look at specialized software packages for remote maintenance of computers.
If you try to classify remote computer programs, you can mentally divide them into two types: utilities that provide access to the desktop of a remote PC, and utilities that provide access to the command line of a remote PC. The first of them will ensure that clients are able to work from a remote PC as well as from a local one. Utilities of another type allow you to automate the work of networks, launching the same different programs on several selected computers, and, for example, create a schedule for launching programs on remote PCs. It’s completely worthwhile to compare these two types of utilities, which are used in different situations and for different purposes.
It is significant that most programs for remote management of functions operate on the “client-server” principle, so that the server and client parts of the programs are respected, which are installed on a hardware computer. and a PC from which control is carried out. To regain control over a remote PC, it is necessary for the external program module (server part) to be running on the new PC. Remote server utilities allow you to remotely install the server part (subject to the availability of specific administrative rights), and this procedure is absolutely transparent for the local PC user (depending on which version of the server part you install it in) There is a service on a remote PC). These utilities also require “manual” installation of the server part of the program.
This article pays attention to remote control programs oriented towards Windows platforms. Please note that in the process of preparing the publication, we looked at dozens of utilities for remote PC management (fortunately, they are easy to find on the Internet). However, as it was clear, not all tools are practical and will contribute to the riddle. Therefore, we focus less on these of them, which are truly effective and have been verified by us at a real local level.

Access Remote PC 4.12.2 provides two modes of operation: the mode of full control of the remote PC and the monitoring mode.
To a limited extent, this utility can be explained by the impossibility of remote, one-hour backup of a single PC using a single interface. You can then immediately launch a single session connection (on the same screen), and this will allow you to control your computer on remote computers. Another drawback of the program is the impossibility of remote installation of the server part.

Small 8. Main window of the EMCO Remote Desktop Professional utility
Before starting the program, you can activate the boundary scanner, which allows you to collect reporting information about all computers in the local boundary, about the programs installed on them, about the running of processes, about the version of the operating system, about the installed hardware, etc. In addition to automatically collecting information about computers (which takes a long time to process), PCs can be added to the list manually.
The package allows you to remotely start and stop services, restart and modify your computer. The most important feature of this program is the ability to gain full control over a remote computer - for which it is enough to see the required computer in the list and go to the Viewer tab. If you want to use your computer first, you must install the NetServer service on the remote PC. This procedure can be carried out remotely and is completely unnoticeable for the local doctor. Once the NetServer service is running on the remote PC, you can log in, relinquish control over the servers, and then work with the remote PC in the same way as with the local one. In case of a remote computer, the computer of the local accountant's robot is not blocked; True, if you immediately vikorist Misha, then it’s unlikely that you’ll be able to see it.
The local client does not remove any information about the fact that the computer is backed up, the EMCO Remote Desktop Professional software package can be effectively used for secret visibility of the activities of the client.
Another important advantage of the program is that it allows you to quickly and remotely use a single PC. In this case, a special window is displayed for each session when connecting to a remote computer.
With a few programs, it is significantly difficult to set up under the hour of installing Windows XP SP2 on a ceramic PC. Moreover, as practice shows, the need for adjustment is due to the fact that the patches are installed. Naturally, the program provides detailed instructions for the changes that will need to be made in this situation (more precisely, the program provides the corresponding instructions from the site), but it is cumbersome and impractical to complete.
The demo version of the program is licensed for 30 days and supports up to 25 computers in the local network. The price of the package is based on the number of computers at the limit: 50 computers (minimum number) – 135 dollars; 1000 computers – 1295 dollars.
Radmin 3.0 Remote Control (www.radmin.com)
Of all the products we reviewed, the Radmin 3.0 Remote Control utility from Famatech is the newest - its new version was released in 2007.
This utility is designed to maintain and maintain complete control over the removal of PCs from a local storage area.
Radmin 3.0 Remote Control is equipped with the most necessary features for managing remote PCs and is even easier to set up (Fig. 9). It’s difficult for anyone to master this. The utility works on the principle of a client-server application and includes two parts: the first (server) part is installed on a ceramic PC, and the other - on the PC on which the computer is running.
Small 9. Main window of the Radmin 3.0 Remote Control utility
Before a few programs, you can see that there are a number of options available for remote installation of the server part (Radmin Server) on a hardware PC, so if you need to take back control of any PC, you will first have to install it locally on a new connection module.
In our opinion, the most serious shortcoming of this utility is the presence of a built-in scanner, which does not allow you to select the list of PCs that you can connect to.
Well, the remaining shortcoming, which was revealed during the testing of these programs, suggests that for correct operation of the utility it is necessary to configure or simply enable the Firewall on the ceramic PC in the case where Windows XP SP2 is running on the new one. .
The utility operates in several modes: file transfer, external browsing, browsing, Telnet, and command line mode. A file manager is required, which helps files to be transferred from one PC to another. The program keeps traffic statistics and can encrypt data.
With the help of Radmin 3.0 Remote Control, you can operate both on one remote computer and on a desktop computer, and you can set your own password for each one. To ensure an advanced level of security, you can make additional steps: turn on the password brute-force protection and compile a list of blocked IP addresses.
The remaining version of the program has a lot of new features:
- Windows Vista support;
- text and voice chat with the possibility of holding a conference and exchanging special messages and password protection;
- advances the security system, which will ensure protection from attacks and protection of active data from the border;
- different rights of access for each individual;
- IP filters for limiting access to different IP addresses and submersions.
Please note that this utility shares its functionality with similar utilities in remote kernel. The presence of a built-in edge scanner, the need for local installation of the Radmin Server module – all of this completely interconnects its functional capabilities.
What is most important is that the Radmin 3.0 Remote Control license price is $49. per PC.
Atelier Web Remote Commander 5.59 (www.atelierweb.com)
Atelier Web Remote Commander 5.59 (Fig. 10) is a small utility that, by design, is designed to ensure complete control of a remote PC. It consists of two parts and follows the “client/server” principle. In addition, it is possible to remotely collect information about the hardware configuration of the PC and others. At the same time, it is unlikely to overextend all the possibilities of the utility in this situation, since there are still a lot of sires left that it is unlikely to be successful in using it quickly.
Small 10. Information window utility
Atelier Web Remote Commander 5.59
The obvious shortcomings can be called the lack of completion. In addition, the program does not have a built-in boundary scanner, through which you have to explicitly enter the name or IP address of the computer before you need to connect, which is very manual. However, the main drawback lies in the fact that in order to implement a connection to a remote PC on a new PC, you must first install an additional program module (in which case there are no options for remote installation) and thus configure yoga.
Unfortunately, since we had not set up the program, we were not able to create a remote connection (the connection was made through a local network between two computers running the Windows XP SP2 operating system). The program is paid (the demo version may be the same term), but it is absolutely worthless. Our verdict – “at the heart” is the same program.

Today on forums you can increasingly find topics such as “Show programs for system administrators”, “Which edge programs are better”, “Help selecting programs for a network that consists of N-number of computers” in, servers and such a large number of customers" and etc. .d. What sense is put into the concept of “margin programs” and why are they needed?
Merezhevi programs- This is a security program that ensures the stable operation of the organization’s computer park. I think there is no sense in explaining that all computers in an organization are connected to a single local edge, so programs of this kind are called edge.
Merezha signs with the company two main functions. First of all, it allows the company’s military personnel to work as a single team. And, in other words, the measure helps to more effectively utilize available resources, and helps to share shared and expensive resources between military personnel. For example, a skin-based printer is expensive and ineffective. Using the printer at its best allows you to ensure ease of use.
Merezhev programs are likely to have a lot of problems associated with the network, such as: problems with equipment, hardware and software, information security of the company, inventory of equipment. nya, organization of the underground file system of the enterprise and much more. And although the diversity of computer networks is immediately great, the problems arise from the very same ones. Merezhevi programs can deal with them as quickly as possible.
It is necessary to protect the network against external threats: hacker attacks, viruses, sniffers, etc. Most importantly, the system administrator of the node has to protect the data from internal accounts. People think that if they have seen a personal computer, have been given access to the Internet and access to documents, they can work in a variety of ways without succumbing to everyday criticism and punishment. Well, for example, watch a bunch of films. Well, the Internet in the organization is unlimited, a gigabyte more, a gigabyte less, what's the difference? Or take the new video card home and install your old one at the place. Still, she doesn’t know anyone, which means she doesn’t know. Merezhevi programs are recognized.
You can fix the system without any knowledge, without any second thought. For example, bring infected files to a flash drive from home and drop them into your bedroom folder. Viruses have the potential to spread uncontrollably as the light winds down, and relief from them usually appears a day or two later. Information security activists have already realized that hacker technologies are constantly being developed by hackers, and computer criminals are always ahead of the curve. Therefore, new techniques will increasingly focus on preventive detection of damage to information systems.
In order for the administrator to be aware of what is happening in his computer park, the programs are responsible for responding to all emergencies in the meantime. For example, it will be overdue for any installation, because... You can tell about either a breakdown or a failure of an important service.
Merezha programs are responsible for responding to the movement of the traffic limit seen on the organization or office, or to a drop in the speed of the Internet connection. The reasons for these phenomena may be unidentified: from not a dull sleeper who watches movies during the working day and watches the channel, and problems with network services, to an unreasonable provider.
Most often in the organization of monitoring programs, clicks help the system administrator or IT manager to carry out an inventory of assets and review them. In this situation, when it comes to the company's intangible assets and power, it is important to inform the system administrator about problems that have arisen. We also talk about the honesty and trustworthiness of the soldiers!
With all of this said, there is a very obvious follow-up: don’t avoid the breakdown of your equipment, but resolve all the problems that arise in the boundary, and immediately notify the administrator about the problem that has occurred - even before besides, how on your head will the cries from the korystuvachs fall on you about those , scho “do not work”, “do not enter”, “galmu”.
Vector 2D editor CADE for Windows developed by a company that specializes in CAD robots. The program allows you to easily create a report diagram. One of the most useful functions, in my opinion, is the ability to sign an IP address, a serial number and the name of the manufacturing company for a skin device at a time. CADE includes all the templates necessary for folding diagrams and can be used absolutely without any hassle.
Concept Draw Pro is one of the most powerful business tools for creating diagrams, and not less than that. It takes at least an hour to master the program - all operations involve simple tightening. Concept Draw Pro comes with a new set of border symbols, all aspects of the diagrams can be personalized. Variety of programs – 249 dollars.
Dia - open the software to create diagrams, the main drawback of which is an outdated interface and a primitive character set. Then the program is very easy to use, without having to rely on everyday third-party services. Dia expands cost-free and works on virtually all desktop Linux distributions.
Diagram Designer is another cost-free utility with an outdated interface, but it is very easy to use, which is exactly what rich hackers like. Under Dia, the program offers a significantly wider selection of symbols and icons. The only thing that Diagram Designer did not suit me was the need to manually draw connections between computers, for which a sufficient form is provided in the program. This is a small shortcoming, DD is a complete decision.
eDraw Max is one of the most powerful tools on this list, obviously Visio. The program is easy to learn, user-friendly, and has the best user interface among all the options available. eDraw Max is a semi-functional tool for creating business diagrams for any purpose, and not just outline diagrams. The price of the solution is 99.95 dollars per license, and the more licenses, the cheaper the cost of them.
There are a lot of programs out there, and GoVisual Diagram Editor is one of them. This is a foldable tool that will provide far from satisfactory results. If you want to use this help, you can still put together a diagram of the fence, but it won’t be very easy to read, but the GoVisual Diagram Editor has all sorts of basic functions - frames, icons of edge devices. If anyone needs a cost-free program for creating diagrams for any purpose, GoVisual is just the right option, because it expands for free.
I turned on LanFlow until the number of the last ones. The program has a wonderful interface, offers a rich selection of boundary objects and allows you to easily create local, telecommunication, external boundary schemes, as well as computer diagrams. LanFlow has two different templates for border diagrams: a 3D diagram and a black and white one. To create a diagram, all you need to do is select a template and drag it onto new subordinate objects that can be grouped and deleted. A single-cost license for the program costs 89 dollars, so LanFlow can rightfully be called one of the best budget alternatives to Visio.
Although NetProbe can be used for complex schemes, the main purpose of the program is monitoring of edge devices in real time. The main advantage of NetProbe, as a feature for dynamic diagrams, lies in the fact that intermediate devices can be added to the diagram if necessary, and sent from afar. There is no need to do it manually - once installed, the NetProbe component automatically scans the network and creates a list of all devices available for the network. The Standard version is cost-free, and can be combined with all hosts. The Pro version costs just $40 and is available for 20 hosts, while the Enterprise version, which allows monitoring of 400 hosts, costs $295.
Network Notepad (literally “margin notebook”) is exactly what the name suggests - a notepad for creating grid diagrams. Despite its simplicity, the program has a lot of capabilities, including interactive functions (Telnet, monitoring, pinging, etc.). Network Notepad has a simple drag-and-drop interface and automatically detects Cisco devices. The program is running smoothly throughout.
Visio is, of course, the de facto standard on the market of add-ons for drawing diagrams on Windows. The program allows you to easily create beautiful border schemes and provide easy access to them via a web browser. Visio includes a wide range of templates, including for data processing centers, help desks, and boundary risers; for office consolidation, enterprise-scale planning, data center and home office; for folding wood faults, plan scorching, ventilation, air conditioning etc. Premium 2010. A report on the possible versions can be read on the official Visio website.

Cost-free Virtual Network Computing (VNC) programs.
Virtual Network Computing (VNC)- a system for remote access to the computer desktop, which uses the RFB (Remote FrameBuffer) application level protocol. Connection with a remote computer is accomplished by transferring keystrokes on the keyboard and moving the mouse pointer from one computer to another through a gap. On a computer, the server part of VNC (VNC server) is used, on a computer, the client part (VNC viewer) is used. VNC does not exist on systems that run it and, for example, a client for Linux can connect to a VNC server that runs in a Windows environment. There are also sales of VNC for Java, including for mobile phones.
The RFB protocol was developed quite a long time ago and was first used to transfer a buffer to the screen using a simple coding method. Raw Encoding- if the server transfers the screen points to the client in the order of left to right and downward. After transmitting the first buffer, only the pixels that changed were transmitted to minimize traffic. With this method of encoding and a small step of changing the image, traffic is minimal, however, for example, when watching a video, the demand on the transmission channel increases sharply, the fragments in the screen buffer will change almost all pixels. To minimize exchange traffic, VNC systems began to use different methods of encoding and compressing the data that is transmitted. Not all methods are standard for skin-to-skin implementation of VNC. Since the RAW Encoding method can be modified in any VNC system, specific methods (CopyRect, Zlib, CoRRE, etc.) are included in the software that is modified, and may vary for different versions of VNC . The ability to encode the data that is transmitted between the client and the server depends on the established connection.
For data exchange, the RFB protocol uses a range of TCP ports from 5900 to 5906. Each port is assigned its own screen of the graphics server (for Linux - terminals 0 - 6 of the X server, Windows - desktop number display 0 and TCP port 5900) . Some VNC implementations allow a return connection from the server to the client via TCP port 5500.
Many cost-free sales of VNC may be a commercial option that offers additional opportunities to ensure reliability, increased security and productivity.
One of the simplest and most useful representatives of the VNC family is RealVNC. The product is available in 3 variants:
- Free Edition- Cost-free version with support for the basic capabilities of the server and client parts.
- Personal Edition- paid version for use at home and in small businesses. Add the possibility of encrypting data, chat, and remote friends.
- Enterprise Edition- commercial version with improved authentication, data encryption, remote communication, chat, file transfer.
The installer includes both server and client parts. The server can be configured to run in user mode (User-Mode) or as a system service (Service-Mode). In the system service mode, the server startup is canceled automatically when Windows starts up. In this mode, the VNC server is ready to accept input connections without logging in to the system and any other actions. In the server mode, the server is started manually or through autostart, as a primary application program.
The configuration of the VNC server is configured either by clicking the context menu by clicking the right mouse button on the icon at the end in the Windows command panel (menu item "Options"), or by launching from the shortcuts in the menu "Programs" - "RealVNC" - "VNC-Server: " - "Configure VNC Server" . During the server configuration process, minimal settings are required - authentication method and password for connection (tab Authentication):
No Authentication- Requiring a password when the client is connected to the server does not change.
VNC Password Authentication- Connection to the server with verification of the password specified by the configured server. The password is set when pressing the button Configure. In many low-cost versions of VNC, the password for the password is 8 characters. If you set a password for a long time, then the first 8 characters will be used to verify the password, so we will not be able to break the server for malicious password selection. Moreover, the number of attempts to enter the password is not verified. In paid versions, the security is significantly improved, since you can break old passwords, encrypt data and verify access using additional Windows features ( NT Logon Authentication mode)
Connected settings are listed on the tab Connections:
Accept connection on port- accept connections on TCP 5900. The port number can be changed as required.
Disconnect idle client after (seconds) - the hour of client inactivity in seconds, after any connection will be disconnected.
Serve Java viewer via HTTP on port- maintain the connection of a Java client that connects via the HTTP protocol to port 5800. If this configuration item is selected, connection to the VNC server is possible in a browser window with Java support.
In the field Access Control You can set connection processing rules for certain IP addresses or connections. For skin recording, there are 3 options for treatment:
Allow- Allow connection. In the window with the list, the address is displayed with a sign +
before the address.
Deny- Protect your connection. In the window with the list, the address is displayed with a sign -
before the address.
Query- Looks like it will ask for permission to connect. In the window with the list, the address is displayed with a sign ?
before the address.
Service modes for connecting clients can be adjusted on the tab Sharing:
Always treat new connection as shared- Always treat the new connection as if it were a lie.
Never treat new connection as shared- Don’t interpret the new connection as a lie.
Use client's preferred sharing settings- Configure the client settings for the designated connection that is shared.
Non shared connection replace existing ones- The connection that is not separated replaces the original. When this mode is installed, a new client connects with a connection sign that is not separated, the server ends and drops all other connections. To connect multiple clients to one, the server needs to remove the order.
Tab Desktop Indicates the parameters for processing the desktop buffer when VNC clients are connected, and what to save after connecting to the remaining server. .
While connected- actions when the client is connected to the VNC server
Setting the proportions for the skin fields will change the traffic during the exchange of the buffer on the desktop, and will also slightly simplify your new appearance. It should be turned on when the speed of the data transmission channel is low.
When last client disconnects- if the remaining client gets involved.
- Do nothing - don’t do anything.
- Lock Workstation – lock the work table. The user's session will not end, unless you enter the user's name and password to continue working at the desktop.
- Logoff user – log out the client from the system.
Tab Modes Inputs indicate the interaction between the client and the server when processing the keyboard and the bear. The "Disable local inputs while server in use" mode will vibrate the keyboard and mouse on the remote computer during the hour of connection to the VNC server.
Tab Capture method sets the desktop image processing mode for the hour of data transfer from the server to the client and processing of clear windows (Alpha - blended windows). Changing modes increases the traffic between the client and the server, as well as the consumption of central processor resources when processing the desktop buffer.
RealVNC server settings are saved in the registry section HKLM\SOFTWARE\RealVNC\WinVNC4
Client Real VNC Viewer After launch, a window for connecting to the server appears. The entry field contains the name of the IP address of the remote computer, and, if necessary, the port number, for example 5909:
Button Options allows you to configure modes for the client part of RealVNC. The Settings window has a tab Load/Save For additional help you can save precise adjustments to files with extensions .vnc Or save the settings to the file before saving. This allows you to create multiple installation profiles for connecting to different VNC servers. The work is adjusted to average productivity and average brightness on the desktop.
Tab Color & Encoding Allows you to select the data encoding mode during the transfer of the desktop buffer and the depth of your color. You can select one of 3 types of coding or set the mode Auto Select- if you select it, it will be selected automatically when the connection to the VNC server is established.
Glibina coloru Color Level This means the display capacity of the remote desktop and the data transferred from the server to the client. Minimal traffic and the best images correspond to the mode Very Low (8 colors)
Setting up the tabs Inputs Much like setting up the server and accessing the parameters of input devices - keyboards and mice
Field Menu Key- Designates a special key for clicking the menu for interaction between the client and the remote desktop. Vikoryized to send special key codes (CTRL, ALT, CTRL-ALT-DEL:) Behind the scenes as a menu key is vikorized F8. How to transmit special key codes, pressing F8 Allows you to click on the client setup menu, switch to full-screen mode, create a new connection and view more detailed information (Connection Info:). Information about the connection includes the IP address and name of the remote server, screen size, pixel format, encoding method, coding protocol, and approximate speed of data exchange.
To install the server part on a remote computer, you can quickly use a no-cost utility pushVNC. The program allows system administrators to install a VNC server installed on a remote computer onto a local network without any need for an end user.
To connect to a remote computer, you need a cloud account with administrator rights. In addition, on the remote computer, the ADMIN$ and IPC$ edge resources may be available, and the remote registry maintenance service may run. The program copies a number of files for creating a VNC server to a remote computer, registers a new PushVNC service in the registry and finally launches it. Then the initial client connection to the remote server is connected. If the mode is not set Leave Service, then after the creation session is completed, the server and the copied video files are deleted.
RealVNC is one of the simplest and most cost-free implementations of VNC. In addition, there are still a few dozen that are divided into insignificant quantities. For example, the popular UltraVNC package has practically the same setup as RealVNC, but allows you to use more data encoding methods, encrypt data in the computer-free version, you can use a special power driver for processing the desktop buffer . And just like RealVNC, the UltraVNC server in the no-cost edition will shorten the password to 8 characters. Below is a short description of cost-free VNC implementations on the SourceForge project.
