There are many programs that help make a remote connection to a computer. Initially, the tool was used by local network administrators to work with a server or a faulty user computer. It was especially convenient to use remote access if the workstation is at a great distance.
Principle of operation
The principle of remote access is based on connecting one computer to another using a special protocol. Basic requirements: a stable connection to the Internet or local network. Remote connection to a computer opens a socket between two workstations. One of the free ports opens for the connection. In the standard application for Windows -
Remote Desktop Connection - a connection occurs between two known IP addresses. In practice, the situation is much more complicated. In the local network, workstations “hide” behind the IP addresses of the gateways without their own external address. It is impossible to connect to a computer on the local network from outside using such a program.
To do this, a number of applications have been developed that not only connect two computers with specific addresses, but can also forward data packets to an IP address on the local network. This made it possible to remotely connect to another computer from anywhere in the world. Connection is also available from mobile devices.
Remote Access Features
Remote access programs allow you to:
- See the desktop of the remote computer.
- Perform settings on a remote computer.
- Remotely install programs.
- Share files.
- Track the status of a remote workstation.
- Take pictures or record what is happening on the remote screen.
- Encrypt transmitted data.
Some applications have built-in text, audio or video chat. Modern tools for remote access provide the opportunity for conferences, connecting to a webcam and a remote projector, other network devices. You can make settings without connecting to the screen. Many programs allow you to use the command line or the Telnet protocol on a remote computer. The developers also offer server-side options for programs that allow you to organize remote access throughout the local network without much difficulty. Naturally, such programs monitor the status of the network, the number of computers and devices in it.
Application
Mostly, remote access is used for large corporate networks. With it, you can configure a computer that is at a distance. Thanks to remote access, the system administrator does not need to be present near the server. With remote access, the server can do without a monitor. The distance to the computer can be any. In the administration of computer networks, remote access is widely used for various purposes. The administrator can help the user, train him, troubleshoot.
Remote access is useful for using a shared resource. Work, obtaining information from the database, general documents - all this allows you to organize special programs.
More and more users are installing remote access programs on their computers. The main condition for remote access is a turned on computer and a running program. With a stable, high-speed Internet connection, you don’t have to regret that the connection to the remote computer is lost. With the latest applications, you can connect to your home network from a smartphone or tablet. Users can monitor the status of the home computer from a distance. Remote access programs are a good way to help a friend. Remote access can be used by parents to monitor the actions of a child at a computer. No matter what you think, software developers have already envisaged such an opportunity.
Teamviewer
One of the most popular programs for remote connection is TeamViewer. The principle of operation is simple - the same version of the program must be installed on both devices. Each user is given a personal identification number. Knowing him, you can connect to a remote computer. The application has a test and commercial version. The program for connecting the remote computer directly from the file is loaded, it does not need installation.
Ammy admin
Absolutely free program. Installation is not required, the application is launched from a file. It is necessary that the program is launched on both computers between which the connection is established. In addition, the first time you connect to a remote computer, a confirmation message appears. It is necessary to allow the connected series of actions. Remote connection to a computer works with a relatively slow Internet connection and does not break the connection.
R-admin
The program allows you to manage multiple computers on your network. The application uses internal IP addresses to connect. The program is often used for corporate networks, computer classes. Despite the fact that this is a serious tool, mastering the program is easy. The program is commercial, but has a trial version for 30 days.
LiteManager Pro
This is a modern program with support for Windows Aero. It works in complex networks. Has a 30-day free license and paid version. The program allows you to monitor the operation of the hardware of the remote computer, manage power. Remote connection to a computer occurs by identification numbers. Using the special NoIpServer application, you can configure the entire corporate network to work with LiteManeger.
Hidden administrator
This program allows you to run up to 256 computers on a network. It has a wide range of data protection tools - password protection, encryption, and the ability to differentiate access rights. The application supports clipboard transfer. This means that if you need text or a picture from a remote workstation, you can simply copy it to your computer. Not all remote access programs allow this. Usually it was required to save the file and use the data exchange function. There are test and commercial versions.
Anyplace control
This is a simple and easy program with a large set of useful functions. It does not “steal” computer memory at all and does not give a load on the network during operation. The application supports a high level of security and data encryption. Clipboard transfer facilitates data transfer. A trial version for 30 days is offered, as well as a full commercial license.
Conclusion
You can continue to list programs for remote access. There are many free applications for the home network, server-side enterprise applications. The choice always depends on the end use. The developers have solved most of the issues that arise when using remote access, but the problems remain. Most of the difficulties encountered during remote administration are related to the instability of the network connection. Cases when the inscription “the connection was closed by the remote computer” pops up are not uncommon in the work of network administrators.
Recall that all programs depend either on the connection on the local network or on the Internet connection. The truth of life is that the Internet sometimes breaks at the most inopportune moment. Work in remote access thus becomes impossible. This leads to a number of undesirable consequences:
- Damage to transmitted data.
- Loss of control over the computer.
- Communication breakdown during the conference.
- Inability to save documents.
- Failures in the settings.
- The need to re-create the connection.
It is almost impossible to avoid the gap. Sooner or later, the following message will appear on the screen: “the connection was disconnected by the remote computer earlier”. But something will still help ease the job. Clipboard transfer allows you to quickly copy small amounts of information - you will have a better chance that the connection at this point will not be interrupted. High file transfer speed is also important. Advantages are programs that do not load the network with their presence. Often, the connection is disconnected at a low Internet speed. Programs that support operation at low speeds are less likely to break the connection.
