In computer science - especially official lingering view that properly the work performed must be performed locally. The employer feels safer seeing with my own eyes persons performing management or corrective sensitive network infrastructure or server. At this point one should ask the question - are you sure work in local mode is better than the so-called. telework - which increasingly popular in businesses and corporations being daily bread?

To answer this question we should consider what characteristics characterize both types of work. Local performing actions that require technicians arrival of a certain, domówionej between the company and employer time, the admission of persons engaged in repair work and oversight - especially when the necessary is the entrance to the premises distribution, server and so on. above aspects are not as mundane as it may seem - because most of the maintenance is performed after hours office work or business - when there is no traffic generated when no one use of services and can safely be performed in the event of machine restarts
necessary. Of course the time the work is the result of agreements between the parties, However, the need for local governance in many cases may prove to be not only a problem, but even barrier preventing properly perform their duties.

Local operation is, however, one advantage. In rare cases, it may happen that the device (server, network device) as a result of changes Setup stops responding. In this situation and in the situation complete failure of the device, of course, the personal presence is required technicians. But as long as everything is running smoothly you should consider the model so-called. teleworking. There are tools to work remotely supervising the IT department - so there is no fear that they will not do activities with integrity. In addition, telework does not necessarily mean risk for data. The current encryption protocols such as remote. VPN - AES256 are impossible to break. Not to mention on this occasion of the infamous gap SSL called Heatbleed - which was recently detected and immediately corrected in the SSL library, but these are situations sporadic and remote work has many advantages.

Consider two job prospects - the first is telecommuting as tool for employees, the other as a tool to support information company. Remote access is accomplished through the channels virtual private networks (so-called. VPN) encrypted and protected. This allows the connecting member is located anywhere with Internet access to the local network. of course, possible is the use of a wide range of restrictions and limitations as to the addresses of which is a merger in order to provide an even greater level of safety, although creating virtual networks filtrate enough secured. We are interested in the more remote management within the meaning of IT support companies and institutions. Of course, the most convenient tool is a private network - it allows plugging devices diagnostic and software for customer network and current monitoring her condition. Unfortunately, not everyone can afford to opening the access channel. Ways are usually lack of adequate equipment, lack of addressing (for small companies) connected to the public the lack of configuration options DDNS services and many others. Of course, for wanting nothing difficult - it is possible to use the tools forming numerous. dedicated private network, eg. Hamachi. there are other methods - such as remote desktop, and even services such as VNC enabling the acquisition of control over the user's desktop. it is extremely helpful - Although the use of Remote Desktop (RDP) integrated in MS Windows user disconnects and can not be to help him in an interactive way, this in turn enables the VNC protocol cooperation. This is the essence of remote assistance - the most common model is the application / VNC session connected with chat or telephone conversation. it solution works best solution to the problem and results in 95%. Similarly, applications that support remote-based architecture client - server example. TeamViewer, Ammy Admin and so on. This software has a crucial advantage over the VNC software. Now, programs like VNC operate only within the network or through a dedicated address public, and the type of software TeamViewer operates independently since held a public address on the basis of their own IDs and passwords. In short: The program starts both the target user as well Remote Assistance contractor. Applications on both sides to connect to the server Team Viewer, which gives them the ID and password. The connection does not take place directly, but through this server. Thanks to that, both machines voluntarily joined him he can establish a connection even if machines are on other networks, are protected by NAT, or whether they only private IP addresses. The only requirement is that both parties connections have enabled access to the Internet and running software. In addition, the software has the advantages of VNC - lets help the current user. There is also a whole range of dedicated software - dependent system based on various protocols such. SSH. From the choice of the color.

The software is encrypted and thus IT services takes place in a secure manner. Part of the software for example. SSH, VNC preserves the transparency - the company may carry out maintenance on active devices eg. network without disturbing the normal of the network. Of course, remote IT support, or so. teleworking requires self-discipline and extensive knowledge as well as skills predicting the consequences of actions. Must be performed in a manner prevent cutting off from the managed machine, otherwise it is not sense.
