The comprehensive Internet is an intricate multi-level connection of a huge number of computers from around the world, so the name "network" characterizes this concept as well as possible. All the information that can be found on the Internet is stored in just all of these machines, many of which are powerful servers that support and support the operation of a large number of services and sites. In all this interweaving of electronics and technology, anyone can access absolutely any machine connected to the Internet.
To prevent this from happening, various protective tools were developed at one time, including antiviruses, firewalls, password-protected access and so on, which continue to develop to this day. Yes, and they are unlikely to stop, since the means and methods of hacking and penetration also become more every minute. The eternal confrontation of the shield and the sword, what can I say. Thus, among the many protections should be highlighted the use of a proxy server.
A proxy server is a complex of programs and technical tools that allows clients to make requests to other network services, as a link between the client and a specific server. In simple terms, the proxy server is a kind of intermediary between the supplier and the recipient, a kind of dealer. This is precisely its protective function - the client cannot access the server directly, but only through such an “intermediary”. Therefore, even bypassing all other protection levels and cracking the proxy, the attacker tears it from the destination server and does not gain access to the information stored on it. This is a simplified but understandable explanation of the proxy.
Proxies can also be used in the opposite direction, that is, to “hide” not your server machine, but your own, not allowing it to leave traces of its IP address on the network. The principle is the same - they cannot calculate you, since formally it is not you who visited a server at all, but a proxy. Here his traces can be calculated quite simply, but there is little sense in this, most often. And in order to allow someone access to your car, you will not be required to do anything except find out your port and tell your friend. Often, as a member of a corporate network, you access the Internet through such a proxy server.
The difficulty is that some programs for setting up their work may “want” to find out their proxy server port - that is, the address through which you access the network. How to find out your port? Very simple - open the properties of your connection on the local network, select the Internet protocol TCP / IP, go to its properties, and if the addresses in the column are not standard 192.168 ..., but something else, then this is your port.
How to find out your proxy port without being a member of the corporate network? Also not very difficult. To do this, download the Mozilla Firefox browser from the manufacturers website, launch it, go to the “Settings” menu item, select the “Advanced” tab and click on “Network”. There will be a full description of your proxy server, if you, of course, use it. The same procedures can be done with the Internet-Explorer browser.
Yes, very often to configure the same programs (for example, FlashGet), in addition to finding out your port, you also need to specify a proxy host. It can also be viewed in IE and Mozilla browsers.
If you still find it difficult to answer the question of how to find out your port, then it is best for you to contact the administrator who serves your network and explain to him the features of the situation. If everything is in order, then he will be able to help you.
