What is a proxy server?
The proxy server is a server between the browser and the web server, when you pass the proxy server
When online browsing, the browser is not directly to the web server to retrieve the web, but issued to the proxy server.
Request, by the proxy server to retrieve the information required by the browser and transfer it to your browser.
What is a free proxy server
When using a software search for the proxy hunter, it will appear in the verification status bar.
Password "," free "and other words. If you set the" free "address to the proxy server, then you will
Will not ask you to enter your password when accessing the webpage. This is the "free proxy server". why
What will free? There are several situations:
1. It is a system vulnerability, once the network management discovery will be blocked;
2. It is a kind network management and other people who have the opportunity to approach the host, set the machine to a proxy server;
3. It is a real kind person, it is to use your own machine as a free agent, and benefit our colleagues. This truth
Good admiration! But it is also the fastest to be closed.
4. It is ISP business to improve impact, it is free to open in a period of time.
Benefits to use proxy servers
Proxy Server is an important security feature provided by the Internet link level gateway, it
The work is primarily in the open system interconnect (OSI) dialogue, the main functions are:
Break through its own IP access restrictions:
1. Access foreign sites. Network users such as education network, 169 networks can access foreign websites through the agent.
2. Visit some units or group internal resources, such as a university FTP (premise is the agent address in this resource
Within the access range), you can use the Detail of the Delivery Server for the Educational Network.
All kinds of FTP downloads open from the Internet are uploaded, as well as services such as all kinds of information query.
3. Break through China Telecom's IP blockade: China Telecom users have many websites being restricted, this
The limit is human, and the blockade of the different serve is different. So you can't access a country when you visit
A proxy server trial.
4. Improve access speed: Usually the agent server sets a larger hard disk buffer when there is an external world
When the information passes, it is also saved to the buffer, and when other users have access to the same information,
Then take information directly from the buffer to transmit it to the user to improve access speed.
5. Hide real IP: Internet access can also hide your IP through this method, free from attack.
6. Hey, free full text.
Going to:
The setup method for the agent in Internet Explorer (for users directly on the Internet, otherwise see the second or multiple agents)
1. Proxy setting method in IE4.0:
Select "View" → "Internet Options" on the main menu → "Access the Internet by Proxy Server", and fill in the proxy server address and port you find, and then click "OK", you can pass the agent. The server browsses the web.
2. IE5.0 agent setting method:
Select "Tools" → "Internet Options" on the main menu → "Settings" → "Using Proxy Server", then fill in the proxy server address and port you find (Figure 1).
Tip: For local area network users, click "The 'LiteNage Network Settings below the' Label" to set the agent.
3. Netscape 4.x proxy setting method:
Select "Edit" → "Preferences" → "Advanced" → "PROXIES" → "Manual Proxy Configuration" → "Manual Proxy Configuration" → "Manual Proxy Configuration" → "View", fill in the proxy server address and port you found, and press "OK".
4. Opera's proxy setting method:
Select "Settings" → "Proxy Options" on the main menu and fill in the proxy server address and port you find.
5. Network ants agent setting method:
Select "Option Settings" → "Parameter Settings" → "Agent" → "Add" on the main menu, and then fill the available proxy server, if the server needs to enter the username and password, select the proxy server option. "Certification" and fill in. Most download software's proxy settings are similar to the network ant, such as flashget.
Advanced:
Where can I find a proxy?
The most original method is to search for a network segment (now there are many search agents on the Internet), but this search proxy server is very time consuming. Usually, everyone will not tell others about the proxy server you use, because people used more speed will naturally be slow. However, there are also many websites and BBS on the Internet to provide the address of the free agent server. You can find a similar website with your search engine (such as Sohu, Swong) to check the proxy or free agent.
Say the search agent software, the first agent hunter, the guide online help, even if you are the first time, there should be no big problem. Specific steps are as follows:
1. From the Internet to as many agent lists (preferably available), save as a .txt suffix text file, the format is as follows:
10.19.193.109:1080@socks4
10.19.193.109:1080@socks5
10.19.193.109:21@ftp
10.19.193.109:80@http
10.19.193.109:8080@http
......
(The above address is exemplified, not necessarily available)
2. Using the Proxy Hunter to the Search Results page, click "Import Results" to import .TXT format a list of proxy.
3. Click the "System" button to select "Parameter Settings".
4. Set the two timeout time parameters in the Verification Settings item in the Search Verification Settings page.
5. Finally, it is of course the check of the Internet.
What kind of agent is a good agent
The standard for agents: fast, stable, of course, the premise is free.
In the agent hunter 3.0 or more, the verification time bar is "time characteristics", the display is similar to this: "0.9│1.0│26.3", "26.3│0.0│26.3", these three times in turn: connection time, first receive data Time, total verification time. Of course, the smaller it is, the better. There are a lot of factors that determine the speed of a proxy, mainly:
1. The network where the free proxy server is located. The big house use proxy mainly to go abroad, and thus, the bandwidth of the export bureau of the four major networks directly determines the speed of Proxy.
2. The performance of the proxy server. The previous article mentioned that Proxy is just a big Cache, so its hard drive size, the bandwidth of the network will affect the speed. This is the same as your own machine.
3. The distance between proxy servers and your machine. Proxy is mainly for a particular object, and its geographical distribution is usually not too wide. And the majority of netizens will not be how far the distance between the proxy you use. Natural, the farther distance, the slower the speed.
4. The situation of the site you visit. This is also the cause of the proxy speed. You have to visit the other party's site, naturally, it is based on the standard of the other party, just like the two speeds of MODEM. Unfortunately, many netizens often ignore this.

How to use the agent to access the blocked website
For some reason, China Telecom shields some foreign websites. All domestic users cannot access it, such as the previous very popular Money Site (SpeIDA), and some foreign websites prohibit China's IP access, the solution is to use Foreign proxy servers. However, if education network users cannot access foreign websites, all foreign agents cannot use it, is we doing power? No, we can solve the use of the secondary agent below. 1. Go to Download a Sockscap32 and fill in the SOCKS proxy server address in the settings.
2. Drag the browser shortcut to the blank box of Sockscap32.
After the networked, start SOCKSCAP32 first. Then fill in the address of the foreign agent server in the browser, run the browser in Sockscap32.
How to use Foxmail to receive through the agent
Can be solved using Sockscap32. Prerequisites: There is a good SOCKS agent that drags the foxmail shortcut to the blank box of the Sockscap32 through a SOCKS agent (SOCKS5 or SOCK4 agent) that can be accessed, and your foxmail can be unimpeded. The same method is also applicable to the Telnet software such as CTERM, STERM to access major BBS sites within the education network, speed up the speed, and hide the real IP address, etc. Sometimes you can resolve the server address, you can use the ping pop.mail.yahoo.com command, then fill the resolved IP address into the Foxmal POP3 server option.
Another law: Suppose you have a POP3 proxy server, such as: 203.95.7.196, your account is
http://mail.ustc.edu.cn/~adamxc/zip/sockscap32.zip
For some friends who have no school IP, only the school proxy, you have to use a three-level agent. Setting up a three-level agent to use HTTPORT SOCKS2HTTP SOCKSCAP to be used together. First search the agent available in the campus, for example: 202.120.25.36 (assuming), use the first level 202.120.25.36 in HTTPORT; or apply for domestic browsing servers (note to fill your account and password). The second level is set to support SSL's free agents in HTTPORT "---> External HTTP Agent". Then use the agent localhost in Socks2HTTP, the port is you "external HTTP proxy" target = " _BLANK "target =" _ blank "target =" _ blank "> WinProxy, Wingate, not our own agent, just use the agent, so do not discuss this problem, (only to discuss how to use the agent, establish a proxy problem to see Wingate, etc. ,Easy.)
Let's talk about some of the software, sockscap, httport, mproxy, these software can be online.
It is very convenient to find that the agent level generally has an HTTP agent and the SOCKS agent for the basis.
There are about the following ways:
1. Cascading between HTTP proxy.
2, cascading between the SOCKS agent.
3, HTTP proxy and cascading of other agents.
4, the cascading of the SOCKS proxy and other agents.
5, cascading between the TLENET agent.
First, the cascading between HTTP proxy
HTTP Agent Class can have a variety of ways, I talk about two kinds, the simplest method is
With MPROXY, it supports the three-level HTTP Agent cascade, supports the address and port of the first two agents, and then use local 127.0.0.1:888 as a proxy to access, it is not as good as the shortcomings of this method
HTTP proxy certification, you can't use the authentication HTTP agent; another method uses httport, actually
This agent is very powerful, now just the cascading between HTTP agents, open HTTPORT, in the Proxy page
Enter the address and port of the first level HTTP agent, if you need to authenticate, select the authentication, enter your username and password.
Then go to the port mapping page, click the Add button, appear in the list, then in Remote
Enter the address of the second-level HTTP agent in Host, enter the port of the second level HTTP agent in the Remote Port.
Enter local listening ports, such as 3128, 8080 and other ports, in the Proxy page Start button
After the local 127.0.0.1:3128 can be used as a proxy, you need to pay attention to the first level HTTP proxy
The SSL connection must be supported, otherwise the second-level HTTP proxy is not allowed.
(The so-called SSL means that Secure Sockets Layer is a set of Internet data security protocols developed by Netscape. The current version is 3.0. It has been widely used for identity authentication and encrypted data transfer between web browsers and servers. It should be noted that although the content you browse is encrypted, the connection site is visible on the proxy server. In addition, the URL and IP of the site are still visible on the proxy server. It is very simple to find SSL agents, you can Use software such as AATools, you can also verify directly with FlashGat)
What needs to be added is that the secondary agent above can be used by others because it is on all local IPs.
The rows listen, if you are 10.9.1.11 in your machine, the local port is 888, others can visit 10.9.0.11:888
As a secondary agent, you can share your secondary age with others, and MProxy introduced here is not
MultiProxy, Multiproxy is made by proxy verification and scheduling.
Second, the cascading between the SOCKS agent
There are several ways to use SOCKS Agent Calcles, and the common method is to use Sockscap to be implemented in Sockscap.
In the Setting dialog box, enter the Socks proxy address, port, such as SOCKS5, and the user and password, then join
Software that can be used with SOCKS agents (free Socks is better !!), such as IE, set the address of the secondary SOCKS agent in the Internet option
And ports, running IE in Sockscap, you can use the second SOCKS agent, like other flashfxp,
Sterm and LeaPFTP are also the same, set the secondary SOCKS agent on these software, then run in Sockscap
You can use the second SOCKS agent; you can also use SKSOCKSERVER to implement, this software support 256
The cascading of the SOCKS agent, it can also be used as Socks Proxy Server, and MPROXY is almost.
Just add the SOCKS proxy address and port at all levels, and the other Sockschain is also a tool for SOCKS cascading.
(The SOCKS agent itself is high. For example, the Ding Ziyuan said that even if you use the agent, you can also find your true IP, but if you ......... ! 嘿!) Third, HTTP Agent and Other Agents Cascade
The HTTP agent is associated with other agents, here is the HTTPOR mentioned above, pay attention to the first HTTP agent
Be sure to be required to connect (must be an agent agent, otherwise !!), enter the address and port of the HTTP agent at the Proxy page, then add other agents to cascaded, such as Telnet agent, in Remote Host Remote
Enter the address and port of the Telnet agent, enter the local listener port in the Local Port, such as 23,
Click Start in the Proxy page, so Telnet 127.0.0.1 23 is connected to the secondary agent, then enter
To remotely log in to the address and port, the cascaded SOCKS agent is also the same, enter the secondary agent in the port mapping page
Address, port, local listener port (such as 1080) so you can use 127.0.0.1:1080 on other software
As a secondary agent, other ftps, POP3 agents are also the same as the secondary agent and HTTP Agent cascade.
Fourth, the cascading of SOCKS agents and other agents
Socks agent and other agent cascade, introduced here is Sockscap, the same as the above, in Setting
Enter the address and port of the SOCKS agent in the dialog, then add other software, such as IE, OE.
And FlashFXP, etc., as long as you enter the address and port of the second level HTTP and FTP proxy in the Internet option,
Running IE in Sockscap, you can use the second level of HTTP and FTP proxy, the same, the other software is the same, set the second level
The agent can use the secondary agent in Sockscap.
5. Cascades between TLENET proxy
In fact, the cascading between the Telnet agent is very simple, with the common Wingate agent as an example, when we telnet
Agent
Wingate>
Tips, enter the address and port of another Telnet agent directly, generally "IP port", some generation
It is "iPort" (such as CSM Proxy Server), you can connect to the secondary agent, enter the secondary agent
The address to be telnet is available.
The above-mentioned number of commonly used agents is introduced, in fact, it is flexible to use HTTPORT above.
Sockscap and other software, as long as you master the use of software, you can play a lot of tricks, such as following
Other software cooperates, as for foreign secondary agents, HTTP proxy can go to Multiproxy's homepage
Go, other agents can enter free proxy http socks on Google to search, latest software
You can get to the home page of the software, finally say, learn from the use of HTTPORT software, for those
Only the HTTP agent, the people who have been sealed in other ports is very useful, don't use these methods to do bad things.
Don't forget to tell me any other good way to tell me Veslin @ SMTH.
(What bad things do you do? The clearing thing to record your work on the proxy server is not easy, just ....... just I want to see movie!)

Can you explain the "SOCKS4 / 5 agent plus SOCKSCAP" upstairs? Because I tried, it is not very successful ...
--------------------------------
1. First find a domestic SOCKS4 or SOCKS5 agent, the reason why it is, mainly to avoid international traffic. At the same time, users in the education network must pay attention to, and different school defined free traffic IP sections are different. In order to protect you from huge traffic expenses, be sure to confirm that the free Socks agent is free! ! !
2. Run SOCKSCAP ---------- File ----------- Set ---- Fill in the agent (distinguish SOCKS4 and SOCKS5)
3. Fill in: New - Browse --- Software you have to run (such as IE) ---- Determine.
Remember, each time you have to run the software, only running from scokscap! ! !
Three-level agent:
Three-level agent
Use HTTPORT S2H SOCKSCAP: Use the first level agent in HTTPORT (note to fill in your account and password) Second level to support SSL's free agent, "port mapping" in HTTPORT ---> External HTTP Setting upon agents.
Then in Socks2HTTP, the Localhost port is the local port you use in the "external HTTP proxy". The following steps are to use Sockscap, launch IE inside, the agent who can download the literature, add agency to IE Fill it.
