New Proxy Server Application Guide

First, I want to explain that the Proxy here is the Proxy Server. Its English name is Proxy Server. In general, there are three roles for ordinary Internet users (not to mention some advanced functions, because we may not use them)

First, we can access websites that we cannot visit at ordinary times. If you don't believe it, you can open your browser and enter the URL "www.geocities.com. How? You don't have to wait for the browser here. It's not that your network speed is slow or you don't have this website, but that you cannot access it (there are many such types of websites on the network ). Why can't I access it? This is a problem... there are many kinds of arguments, most of which say that the domestic network is restricted to access, so some websites cannot go. How can I access these websites? After reading this article, you will know!

Second, we can use it to speed up browsing certain websites. Sometimes we access some foreign or Hong Kong and Taiwan websites, and the speed is as slow as a snail bait. However, as long as you select the proxy server correctly, the speed can be improved. Sometimes the speed improvement is obvious!

The third is to connect the Internet to the Intranet and act as a firewall (firewall): Because All Intranet users access the outside world through the proxy server, only one IP address is mapped, so the outside world cannot directly access the Intranet; at the same time, you can set IP address filtering to restrict Intranet access to external networks. In addition, two Intranets without interconnectivity can also exchange information through third-party proxy servers.

If you have seen the above situations in the previous browsing process, it seems necessary to try to use the proxy server.

Why can I use a proxy server to access some websites that cannot be accessed? Why is it faster to use it to browse foreign websites? The proxy server is a transfer station for network information. In general, when we use a web browser to directly connect to other Internet sites to obtain network information, we must send a Request signal to obtain the answer, and then the other Party sends the information back in bit mode.

The proxy server is a server between the browser and the Web server. With this server, the browser does not directly go to the Web server to retrieve the Web page, but sends a request to the proxy server, the Request signal will be sent to the proxy server first. The proxy server will retrieve the information required by the browser and send it to your browser. In addition, most proxy servers have the buffer function, which is like a large Cache, which has a large storage space and constantly stores new acquired data in its local memory, if the data requested by the browser already exists and is up-to-date on its local memory, it will not retrieve data from the Web server again, directly transfer the data in the memory to the user's browser, which can significantly improve the browsing speed and efficiency (the speed will change with the geographical location of the proxy server and the network transmission situation ), in addition, most of the foreign networks do not restrict access to websites or are different, so we have a great opportunity to access those websites that could not have been accessed through the proxy server.

More importantly, the Proxy Server is an important security function provided by the Internet link-level gateway. It mainly works in the Open System Interconnection (OSI) the dialog layer of the model.
Proxy is so useful to us, so how can we find these servers on the novogene network? This depends on some software that specifically looks for proxy. Below is an introduction to several common software:

1. Proxy Hunter
This is the old brother of the Proxy search software. since its launch in 1.0, it has been favored by netizens all over the country. The current version is 3.0. What are the characteristics of this Proxy Hunter? The search speed is the first among similar software and provides the ability to predict the time when a search task is completed. Besides the education network, the search IP address range is not limited, it also supports search and verification of HTTP and SOCKS proxies, and provides advanced functions such as managing, using, automatic scheduling, and re-verification of the searched Proxy addresses. When there are a lot of proxies and you don't know which one to use, you need the automatic scheduling function to set the Proxy of the network software to the local IP address (127.0.0.1), port 8080, then, in the Proxy Hunter search result list, right-click the Proxy you want to use and set it to "Enable". In this way, Proxy Hunter will speed up and down each Proxy at that time, it is convenient to select one or more instances.

2. Proxy NOW Series
This is developed by the author of the Update NOW software for the website. It consists of three parts: HTTP Proxy NOW, SOCKS Proxy NOW, and FTP Proxy NOW. As the name suggests, the functions are used to search for the above three types of proxies. If they can be integrated into one software, the advantage of the Proxy NOW series is that there is absolutely no restriction on the search IP range, but there will be a delay when you do not register for the entry, but only a few seconds, no problem, and the search speed is acceptable. The disadvantage is that the functions are scattered and there are few configurable items, the verification is not so complete.

3. SOCKS Cat
This is a dedicated SOCKS Proxy search, which also does not limit the search IP address range and is faster. According to the author, it is only slower than Proxy Hunter, however, it is necessary to do a good job in verifying SOCKS Proxy. It also supports searching and verifying SOCKS S4 and SOCKS5 Proxy, setting the webpage for verification, setting the maximum number of connections, etc. After actual use, the effect is good, it may be better if you can add the search and verification functions for HTTP Proxy.

Conclusion: the three methods use Proxy Hunter as a better choice, but they cannot be hanged by a tree. We should analyze the specific situation and select a suitable one.

Of course, some search experience should also be mastered, search Proxy, such as haystack, do not master the essentials, but to eat a big loss. Large-scale search, good results, but high cost, long time consumption, is not recommended. After practice, it is better to search IP address fluctuation in some regions. For example, if you have a large ISP or ICP in your location and assume that the IP address is 202.96.123.123, then take the total number of 1275 (255 × 5) as the fluctuation range, calculate the search range from 202.96.121.0 to 202.96.125.255. Good luck! There is also a longer connection time, and note that adding the following port 8080 (HTTP) 3128 (HTTP) 80 (HTTP) 1080 (SOCKS) will not cause any leakage.

The following uses ProxyHunter as an example to explain how to search for a proxy.

After filling in the task, return to the main interface and press the blue start key, so that ProxyHunter will start searching for the proxy. What you need to do now is to keep an eye on the search results bar and wait patiently.

Server address: the IP address of the proxy server you searched for appears.

Port: This is the port it uses.

Type: the Proxy type.

Verification status: This is the most important. The status is listed in several States. If the proxy is successfully searched, it is displayed as "FREE ", then you can directly use this proxy. If it is displayed as "Password required", you can delete this proxy, unless you have the ability to crack the password ...; if other statuses such as "connection timeout" or "connection failure" are displayed, your current network may be busy or the proxy may be temporarily disabled, you can verify it again later.

Time Characteristics: This value affects the proxy speed. It shows the time when your machine is connected to the proxy. If you have multiple proxies for your choice, select a smaller value. The smaller the connection time, the faster the porxy.

After the previous search, you must have searched several proxies with the "Free" attribute? Congratulations ~

So how can we use these proxies? In fact, it is very simple. Most software has software attributes, such as "Setting" and "Preferences. In these options, the "Proxy" option is usually available. You only need to fill in the "Proxy" option with the port of the Proxy IP address you searched, then you can use this Proxy. If the software is Chinese, it is simpler. You just need to fill in "set Proxy Server.

Take IE 6 as an example:
1. Open "Internet Options" in "Tools ".

2. Click "connection.

3. If you use dial-up Internet access, select "Settings ". If you are using a LAN, select "LAN Settings ".

4. There is the "Proxy Server" setting in it. Click "use Proxy server" first, then fill in the Proxy IP address on the "Address", and fill in the port on the "Port! Success.

Proxy server search and Verification

I. Common server ports
Each host (Hosts) on the Internet has a unique IP address, but the same host may provide more than one service at the same time, for example, for FTP service and WWW Service, each service occupies a PORT of the host ).

Common ports on the proxy server include:

HTTP Proxy: 80/8080/3128/8081/9080

SOCKS Proxy: 1080

FTP Proxy: 21

Telnet proxy: 23

2. How to search for proxy servers
From the above content, we know that finding a Proxy server is actually to find out the server's IP address, service type, and port used. We can use the "Proxy Hunter" software to search.

Briefly introduces how to use the Agent Hunter:

1. Start the proxy Hunter and enter the starting address and ending address in the "IP address range" in the upper-left corner. For example, if you want to find the proxy server in the IP address segment 210.62.0.0 --> 210.63.0.0, enter 210.62.0.0 in the left column, enter 10.63.0.0 in the right column. Click the [add address] button, and the address segment will be added to the search task.

2. Select the port range. The proxy hunter supports searching for HTTP proxy and SOCKS proxy. You can add frequently used ports of the two proxies listed above. Add method: Enter "8080" in the first blank column of "port range", enter "8080" in the second column, select "HTTP" for the type, and click the [add Port] button, you will find "8080 | 8080 | HTTP" in the port list ". Add the following ports as follows: "80 | 80 | HTTP", "3128 | 3128 | HTTP", "8081 | 8081 | HTTP", "9080 | 9080 | HTTP", "1080 | 1080 | SOCKS ".

3. Click the [parameter settings] button and change "connection timeout" of {search verification settings} to 6, "Verification timeout" to 30, and "concurrent connection count" to 100; change "connection timeout time" of {verification settings} to 45, and "Verification timeout time" to 90. If these values are too small, the proxy address cannot be found completely. If the value is too large, it will waste time = money. Return after confirmation.

4. Click the [start search] button. The proxy server is displayed in the list at the bottom left, free proxy servers are available only when the verification status is displayed as "Free x seconds.

Iii. How to verify the Proxy Server
The proxy server can be said to be not very stable. Some of them were used well yesterday and cannot be used today, or they need a password. To find out whether the proxy is still Free, we need to use the "Agent Hunter" verification function. There are eight buttons at the bottom right of the Agent Hunter. The first one is "test" and the second is "test all". We can press [test all] to verify whether all agents in the list can be used, you can also select one or more proxy addresses in the list and click [verify] to verify that only these proxies are usable. After the verification is complete, click "Verify Status" in the title of the List to arrange the available proxy servers in front of the list for easy search.

4. How to export and import results
In the text file of the volume (use the proxy hunter version 3.0 to note that at least the "type" under "Content Setting" should be selected during export and exported together ), then pass the file to your friends. After obtaining this file, your friend can use the [import result] button to introduce these addresses to his "Agent Hunter" list (Use Agent Hunter 3.0 to note that, when using the import results, when the select file dialog box is displayed, You must select the "avoid repeated import items" at the bottom to avoid duplicate addresses in the list ).

If you find the proxy address posted by a netizen on the internet, how can you import the address to "Agent Hunter? The method is as follows:

1. Open a text editor (for example, a Windows notepad ).

2. Enter an address in the format of "Address: Port @ Type". Each address occupies one row. Note: ":" and "@" are both English Punctuation Marks, and Chinese Punctuation Marks cannot be used. If the type is @ HTTP, it can be omitted as "Address: Port" instead of "@ HTTP. For example:

210.77.125.90: 1080 @ SOCKS5
210.62.225.8: 3128
200.77.125.146: 21 @ FTP
61.173.65.126: 3128
211.78.26.35: 80
132.162.17.194: 21 @ FTP
202.104.141.130: 80
218.63.120.31: 8080
61.78.60.10: 1080 @ SOCKS5

3. Save the file by any name, such as proxy.txt.

4. Start the Agent Hunter, select "Export Import result", find the Newly Edited proxy.txt file, and import it (remember to select "avoid repeated import items ").

5. Select the import result and click [test]. It is clear if it can be used.

5. Tips
When you search for a proxy server, the Entered IP address range is very important. Generally, when you set up a proxy server to a large number of economically developed regions, you can find the IP addresses of each province and city in China, then perform targeted search.
