Programs for the local network. Remote control programs for a local area network. Browser add-ons

Greetings to all readers.

Most computer games (even those that came out 10 years ago) support multiplayer games: either over the Internet or over a local network. This, of course, is good, if not for one "but" - in many cases, it will not work to connect to each other without using third-party programs.

There are many reasons for this:

For example, the game does not support playing over the Internet, but there is support for local mode. In this case, you must first organize such a network between two (or more) computers on the Internet, and then start the game;

Absence of a "white" ip address. It's more about organizing Internet access by your provider. Often, in this case, you cannot do without the use of software at all;

The inconvenience of constantly changing the IP address. Many users have a dynamic IP address that is constantly changing. So, in many games you need to specify the IP address of the server, and if the IP changes, you have to constantly drive in new numbers. In order not to do this, specials will come in handy. programs…

Actually, we will talk about such programs in this article.

GameRanger

Supports all popular Windows versions: XP, Vista, 7, 8 (32/64 bits)

GameRanger is one of the most popular programs for playing on the Internet. Supports all the most popular games, among them there are all the hits that I simply could not fail to mention in this review:

Age of Empires (The Rise of Rome, II, The Conquerors, Age of Kings, III), Age of Mythology, Call of Duty 4, Command & Conquer Generals, Diablo II, FIFA, Heroes 3, Starcraft, Stronghold, Warcraft III.

In addition, there is just a huge community of players from all over the World: more than 20,000 - 30,000 users online (even in the morning / night hours); about 1000 created games (rooms).

During the installation of the program, you will need to register by specifying a working email (this is mandatory, you will need to confirm the registration, moreover, if you forget your password, you will not be able to restore your account).

After the first launch, GameRanger will automatically find all installed games on your PC and you can see games created by other users.

By the way, it is very convenient to look at the server ping (marked with green stripes :): the more green stripes, the better the quality of the game will be (fewer lags and errors).

In the free version of the program, you can add 50 friends to your bookmarks - then you will always know who is online and when.

Works in: Windows XP, 7, 8 (32 + 64 bits)

A rapidly gaining popularity program for organizing network games. The principle of operation is somewhat different from GameRanger: if you enter the created room there, and then the server starts the game; then here for each game there are already its own rooms for 256 players - each of the players can start their own copy of the game, and the rest can connect to it as if they were on the same local network. Comfortable!

By the way, the program contains all the most popular (and not popular) games, for example, I made a screenshot of the strategies:

These room lists make it easy to find friends in many games. By the way, the program remembers "your rooms" that you entered. In addition, each room has a not bad chat that allows you to negotiate with all the players on the network.

Outcome: a good alternative to GameRanger (and perhaps soon GameRanger will be an alternative to Tungle, because Tungle is already used by more than 7 million players around the world!).

Of. site: http://www.langamepp.com/langame/

Full support for Windows XP, 7

This program was once unique in its kind: nothing could be found easier and faster in setting up. LanGame allows people from different networks to play games where such an opportunity is not provided. And for this you don't need an internet connection!

Well, for example, you and your comrades are connected to the Internet through the same provider, but in the network game mode, you cannot see each other. What to do?

Install LanGame on all computers, then add each other's IP addresses to the program (do not forget to turn off Windows firewall) - then all that remains is to start the game and try to turn on the network game mode again. Oddly enough - the game will start a multiplayer mode - i.e. you will see each other!

Although, with the development of high-speed Internet, this program is losing its relevance (because even with players from other cities you can play with very low ping, despite the absence of a LAN), it can still be popular in narrow circles for a long time.

Hamachi

Works in Windows XP, 7, 8 (32 + 64 bits)

Hamachi was once a very popular internet LAN program used in many multiplayer games. Moreover, there were very few worthy competitors.

Today Hamachi is more needed as a “safety net”: not all games are supported by GameRanger or Tungle. Sometimes, some games are so "capricious" due to the absence of a "white" IP address or the presence of NAT devices - that there are simply no alternatives to the game, except through "Hamachi"!

In general, a simple and reliable program that will remain relevant for a long time. Recommended for all fans of rare games and connected to the Internet through "problem" providers.

Alternative programs for playing on the network

Yes, of course, many popular programs did not make it to my list of the 4 programs above. However, I was based, firstly, on those programs with which I had experience to work, and, secondly, in many of them online players are too small to be considered seriously.

For example, GameArcade- a popular program, however, in my opinion - its popularity has been falling for a long time. In many games, there is simply no one to play with, the rooms are idle. Although, for hits and popular games, the picture is somewhat different.

Garena- is also a fairly popular program for playing on the Internet. True, the number of supported games is not that large (at least during my repeated tests - many games have not been launched. It is possible that now the situation has changed for the better). As for hit games, the program has gathered a fairly large community (Warcraft 3, Call of Duty, Counter Strike, etc.).

That's all, I will be grateful for interesting additions ...

There are many reasons why you need to connect 2 computers over a local network. For transferring files, for playing games, creating an access point and much more. In this article, we will analyze how to connect two computers without programs. And let's see programs for creating a local network over the Internet.

For all these operations, we need two or more computers, the Internet, and if you want to connect without programs, then you need a network card that supports Wi-Fi technology.

How to connect two computers without software?

For this we need:

• Go to the Network and Sharing Center, and click "Set up a new connection or network".

• Select "Configure a wireless network computer - computer" and click next.

• Choose a name, network type (WPA2 is better, since it will exclude a high probability of hacking your connection), write a password and click on the checkbox: "Save changes for this network".

• After setting, click next and close the window.

Go to the second computer, where you just need to connect to our network.

This method is suitable if 2 computers are nearby, but if they are far away, then, unfortunately, the signal will not be received.

But what if you need to communicate with a friend over a long distance?

To do this, you need to download one of the programs below.

Programs for creating a virtual local area network

If you do not have a license for the game, or you just do not want to suffer with constant copying and pasting of an IP-address, then you can simply download and install a LAN simulator - this is a program for connecting several computers. With the help of such programs, you can easily play pirated or even licensed games over the network, and sometimes find friends there.

There are actually enough such programs and everyone can find a suitable one. It also happens that one of the programs may not work or not support the desired game, as is often the case with Hamachi or other programs, so you can look for a solution to the problem on the Internet or use another program.

Hamachi

This program for creating a local network is presented to Windows users and was the most popular of this list until recently, when significant competitors appeared. It is in her that troubles can occur. "Tunnel through repeater" is a very common problem faced by many users of this program. The best solution would be to simply change it or adjust it in the right way, which is not always easy and not a fact that might work.

Tunngle

Quite a popular program for creating a local network via Wi-Fi and the Internet. With its help, you can connect to each other in the same way as with Hamachi. The principle of operation of this program is slightly different from others, because here you do not need to create a room for a separate server. These rooms are already created for each game, 255 people can enter each room. Quite convenient. This program contains almost all the games that you can play with your friends.

GameRanger

Probably the most popular program for creating and playing with friends. It supports all popular games, but there are also those that are not in the field of its reach. A lot of people are sitting in this program for days and you will definitely not be bored if your friends have gone to bed. The server has a ping, you can see how good or bad the user's connection is. When you first sign up, the program will automatically scan your computer for games. Further, on the main screen, all rooms created at the moment will be shown, as well as the nickname of the person who created the room. Some rooms can be password protected. This means that the user wants to play only with his friends and with no one else.

Evolve

The program is a good analogue of Tunngle, but it is less popular among the audience. But in this program there are no ads and pop-ups that annoy gamers so much. You don't have to mess with the settings right there, because everything is done automatically. But for all its advantages, there are also disadvantages. Evolve lacks the room finder that Tunngle does. Instead, there is something like smart search. You just need to go into the game, and the program itself will find all existing rooms to which you can connect.

Conclusion

There are, of course, many programs for creating a local network, but there is also a way to create a local network without using third-party programs. If you do not trust the Internet and only Microsoft programs are installed on your computer, then there is also a way for you to create a local network. Everything is completely simple and does not need an extra installation of software, however, there are some disadvantages, and it is difficult not to note them, namely: the connection can only occur via a Wi-Fi network, respectively, if you have a PC without an appropriate network card that does not support given technology, then you will not be able to connect to a local network without programs.

Free Virtual Network Computing (VNC) networking software.

& nbsp & nbsp Virtual Network Computing (VNC)- a system of remote access to a computer desktop using the RFB (Remote FrameBuffer) application layer protocol. A remote computer is controlled by transmitting keystrokes on the keyboard and moving the mouse pointer from one computer to another over the network. The VNC server part (VNC server) is used on the controlled computer, the client part (VNC viewer) on the control computer. VNC is independent of the systems on which it runs and, for example, a Linux client can connect to a VNC server running in a Windows environment. There are also implementations of VNC for Java, including for mobile phones.

The RFB protocol was developed relatively long ago and originally used a simple encoding method to transfer the screen buffer. Raw encoding- when the server transmitted screen points to the client in the order from left to right and from top to bottom. After the transmission of the first buffer in the future, to minimize traffic, only the changed pixels were transmitted. With this coding method and a small degree of image change, the traffic is minimal, however, for example, when watching a video, the load on the transmission channel increases sharply, since almost all pixels in the screen buffer will change. To minimize the exchange traffic, VNC systems began to use various methods of encoding and compressing the transmitted data. Not all methods are standard for every VNC implementation. If the RAW Encoding method can be used in any VNC system, then the specific methods (CopyRect, Zlib, CoRRE, etc.) depend on the software used and may differ for different VNC versions. The client and server negotiate the encoding of the transmitted data when the connection is established.

By default, the RFB protocol uses a range of TCP ports from 5900 to 5906. Each port has its own graphics server screen (in Linux - terminals 0 - 6 of the X server, in Windows - a desktop with display number 0 and TCP port 5900 ). In some VNC implementations, it is possible to connect back from the server to the client over TCP port 5500.

Many free VNC implementations have a commercial version with additional usability, security, and performance enhancements.

One of the simplest and most convenient members of the VNC family is Realvnc... The product is available in 3 versions:

- Free Edition- a free version with support for basic server and client features.
- Personal Edition- paid version for home use and small business. Added data encryption capabilities, chat, remote printing.
- Enterprise Edition- commercial version with improved authentication, data encryption, remote printing, chat, file transfer.

The installer includes both server and client parts. The server can be configured to run in User-Mode or as a system service (Service-Mode). In system service mode, the server starts automatically when Windows boots. In this mode, the VNC server is ready to accept incoming connections without the user logging in or taking any action. In user mode, the server is started manually or via autostart like a normal application program.

The VNC server is configured either by calling the context menu by right-clicking on the icon in the Windows taskbar (menu item "Options"), or by launching it using shortcuts in the menu "Programs" - "RealVNC" - "VNC-Server:" - "Configure VNC Server". In the process of configuring the server, the minimum settings are performed - the authentication method and the password for connection (the tab Authentication):

No Authentication- the password request is not performed when the client connects to the server.
VNC Password Authentication- connection to the server with a password check specified in the server settings. The password is set when the button is pressed Configure... Many free versions of VNC use an 8 character password. If you specify a longer password, the first 8 characters will still be used for verification, which makes such a server very vulnerable to brute-force attacks. Moreover, the number of attempts to enter a password is not checked. In the paid versions, security is significantly improved by using long passwords, data encryption, and access verification using Windows tools ( NT Logon Authentication mode)

Connection settings are made on the tab Connections:

Accept connection on port- accept connections on TCP port 5900. The port number, if necessary, can be changed.
Disconnect idle client after (seconds) - client inactivity time in seconds, after which the connection will be dropped.
Serve Java viewer via HTTP on port- Serve connections of Java-client, connecting via HTTP protocol on port 5800. When using this configuration item, connection to VNC - server is possible in a browser window with Java support.
In field Access Control you can set rules for handling connections for individual IP addresses or subnets. There are 3 options for a predefined action for each entry:

Allow- Allow the connection. In the window with a list of addresses, displayed with a sign + before the address.
Deny- Deny connection. In the window with a list of addresses, displayed with a sign - before the address.
Query- Issue a request for permission to connect .. In the window with a list of addresses, displayed with a sign ? before the address.

Client connection service modes are configured on the tab Sharing:

Always treat new connection as shared- always treat a new connection as shared.
Never treat new connection as shared- never treat a new connection as shared.
Use client "s preferred sharing settings- use client settings to define a shared connection.
Non shared connection replace existing ones- a non-shared connection replaces the existing one. When this mode is set, connecting a new client with the sign of an unshared connection, the server will reset all other connections. To connect multiple clients to one server, clear the checkbox.

Tab Desktop defines the parameters for processing the desktop buffer when VNC clients connect, and the actions to be performed after the last of them disconnects from the server. ...

While connected- actions when connecting a client to a VNC server
Setting the checkboxes for each of the fields reduces the traffic when exchanging the desktop buffer, but slightly simplifies its appearance. It is advisable to turn it on when the speed of the data transmission channel is low.

When last client disconnects- when the last client disconnects.
- Do nothing - do nothing.
- Lock Workstation - lock the desktop. The user session does not end, but the username and password must be entered to continue using the desktop.
- Logoff user — log off the user from the system.

Tab modes Inputs define the interaction between the client and the server when handling keyboard and mouse events. Disable local inputs while server in use disables the keyboard and mouse on the remote computer when connected to the VNC server.

Tab Capture method sets the processing mode of the desktop image when transferring data from the server to the client and the processing of transparent windows (Alpha - blended windows). Changing modes affects the amount of traffic between the client and the server, as well as the degree to which CPU resources are used when processing the desktop buffer.

RealVNC server settings are stored in a registry key HKLM \ SOFTWARE \ RealVNC \ WinVNC4

Customer Real VNC Viewer after starting it displays a window for connecting to the server. The input field uses the name or IP address of the remote computer and, if necessary, the port number, for example 5909:

Button Options allows you to configure the modes for the RealVNC client. The settings window has a tab Load / Save with which you can save the current settings to a file with the extension .vnc or load previously saved settings from a file. This allows you to have multiple configuration profiles to connect to different VNC servers. The default settings are based on average performance and average desktop display quality.

Tab Color & Encoding allows you to select the data encoding mode when transferring the desktop buffer and its color depth. It is possible to select one of the 3 preferred types of encoding or set the mode Auto Select- when the selection is made automatically when a connection to the VNC server is established.

Color depth Color Level determines the display quality of the remote desktop and the amount of data transferred from the server to the client. The lowest traffic and the worst image corresponds to the mode Very Low (8 colors

Tab settings Inputs are in many ways similar to the server settings and relate to the parameters of input devices - keyboard and mouse

Field Menu Key- defines a special key for invoking the client interaction menu with the remote desktop. Used to pass special key codes (CTRL, ALT, CTRL-ALT-DEL :) By default, the menu key is F8... In addition to transmitting special key codes, pressing F8 allows you to call the client settings menu, switch to full-screen mode, create a new connection and view information about the current one (Connection Info :). Current connection information includes the IP address and name of the remote server, screen resolution, pixel format, encoding method, protocol used, approximate data transfer rate.

& nbsp & nbsp To install the server part on a remote computer, you can use a free utility pushVNC... The program allows system administrators to install a VNC server on a remote computer over a local network without any end-user intervention.

An account with administrator rights is required to connect to a remote computer. In addition, the hidden network shares ADMIN $ and IPC $ must be available on the remote computer and the Remote Registry Service must be running. The program copies several of its files to create a VNC server to a remote computer, registers a new PushVNC service in the registry and starts it. Then a normal client connection is made to the remotely created server. If the mode is not set Leave Service, after the session ends, the created server and files copied over the network are deleted.

RealVNC is one of the simple and handy free VNC implementations. In addition to it, there are several dozen more, differing slightly. For example, the popular UltraVNC package has almost the same settings as RealVNC, but allows you to use more methods of data encoding, encryption even in the free version, you can use a special native driver to handle the desktop buffer. And just like RealVNC, the Free Edition UltraVNC Server truncates passwords to 8 characters. Below are links and a short description of the free VNC implementations on the SourceForge project.
