What is a proxy server?
Proxy server is a server between the browser and Web server, when you surf the Internet through a proxy server, the browser is not directly to the Web server to retrieve the page, but to the proxy server to send a request, the proxy server to retrieve the information required by the browser, and sent to your browser.

What is a free proxy server?
When using software such as proxy hunter to search proxy server addresses, the words "to password" and "free" appear in the validation status bar. If you set the "free" address to a proxy server, you will find that you won't be required to enter the password when you visit the Web page. This is the "Free proxy server". For what
What happens to free? There are several situations:
1, is the system loophole, once was discovered by the network management will be blocked;
2, is the kind of network management and other people have the opportunity to approach the mainframe, the machine set up a proxy server;
3, is the real kind-hearted people, is their own machine as a free agent for the benefit of our colleagues. This is really
Worthy of admiration! But the seizure was shut down fastest.
4, is the ISP in order to improve the impact, in a period of time free open, generally very short.

Benefits of using a proxy server
Proxy Server (proxy) is an important security feature provided by Internet link-level gateways, primarily in the Open Systems Interconnection (OSI)-Type dialog layer, with the main features:
Break through your own IP access restrictions:
1, visit foreign sites. Education Network, 169 network and other network users can visit foreign websites through the agent.
2, access to some units or groups of internal resources, such as a university FTP (provided that the proxy address within the scope of the resources allowed), the use of Education Network Address section free proxy server, can be used to open the education network of various types of FTP download upload, as well as various types of data query sharing services.
3, the breakthrough of China Telecom IP blockade: China Telecom users have a lot of sites are restricted access, this restriction is man-made, different serve to address the blockade is different. So can not access when a foreign proxy server to try.
4, improve access speed: Usually the proxy server sets a large hard disk buffer, when there is outside information passed, but also save it to the buffer, when other users access the same information, then directly from the buffer out of information, passed to the user to improve access speed.
5, Hidden Real IP: Internet users can also hide their own IP in this way, from attack.
6, hehe, free full text.

Where to find an agent
The original approach is to use software to search for a network segment (now there are many search agents on the Web tools software), but this search proxy server is very time-consuming work. Usually people do not use their regular proxy server to tell others, because the use of more people will naturally slow. But there are many Web sites and BBS to provide free proxy server address, you can use your own search engine (such as Sohu, Sina) Check proxy or free agent, you can find a lot of similar sites.
When it comes to search agent software, the Agent Hunter, the wizard-style online help instructions, even if you are the first time to use should not have too much problem. The specific steps are as follows:
1, from the Internet to include as many proxy list (preferably available), save as a. txt suffix text file, format 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 for example, not necessarily available)
2, the use of Agent hunter to the Search results page, click "Import Results" to import the list of agents in the. txt format.
3, click the "System" button, select "Parameter settings."
4. Set the two timeout parameters in the validation settings entry on the Search Validation Settings page.
5, the last of course is the Internet calibration.

What kind of agent is a good agent
Agent easy to use the standard: fast, stable, of course, the premise is free.
In the agent Hunter more than 3.0 version, the Verification time bar is "The time characteristic", displays the situation to be similar: "0.9│1.3│2.6", "26.3│0.0│26.3", these three time in turn represent: The connection time, first receives the data time, the total verification time. Of course, the smaller the better. There are a number of factors that determine the speed of an agent, mainly:
1, the free proxy server is located in the network. We use proxy mainly to go abroad, therefore, the four networks of export bureau bandwidth directly determines the speed of the proxy.
2, the performance of the proxy server. The previous article mentions that proxy is only a large cache, so its hard disk size, bandwidth of the network will affect the speed. It's the same as your own machine.
3. The distance between the proxy server and your machine. Proxy is primarily for specific objects, and its geographical distribution is usually not too extensive. And the majority of netizens will not be with you use the distance between the proxy is how far. Naturally, the farther away the distance, the slower the speed.
4, the site you visit the situation. This is also the reason that affects the speed of proxy. You want to visit each other's site, naturally to the other side of the standard, like two different speeds of the same modem. Unfortunately, many netizens often overlook this point.

How to use a proxy to access a blocked web site
For some reasons, China Telecom has blocked some foreign websites, all domestic users can not visit, such as the former very prosperous money-making site (Speida), and some foreign websites prohibit China's IP access, the solution is to use foreign proxy server. However, the education network users can not visit foreign websites, all foreign agents can not be used for it, whether we could do nothing about it? No, we can refer to the following two times the use of agents to resolve.
1, to download a Sockscap32, fill in the Settings Socks Proxy server address.
2, drag the browser shortcut to the SOCKSCAP32 blank box.
After networking, start SOCKSCAP32 first. Then in the browser to fill out the address of foreign proxy server, in the SOCKSCAP32 run the browser can.

How to use Foxmail to receive letters via proxy
can be resolved using SOCKSCAP32. Premise: There is a good socks agent, through an accessible socks agent (SOCKS5 or Sock4 proxy), the Foxmail shortcut to the SocksCap32 of the blank box, your foxmail can be unimpeded. The same method also applies to cterm, sterm, such as Telnet software access to the education network of the major BBS site, speed up, but can hide the real IP address and so on. There are times when you cannot resolve a server address by using the ping pop.mail.yahoo.com command and then filling the resolved IP address into the Foxmal POP3 server option.
Another method: Suppose you have POP3 proxy server, for example: 203.95.7.196, your account number is Algam@21cn.com, then in outlookexpress or FOXMAIL30 should be set as follows: POP3 server address Fill in: Proxy server address, 203.95.7.196 (port need not set), SMTP server address is: The original SMTP server address, smtp.21cn.com (in fact, because you do not need to send a letter, so the SMTP server address can be easily filled in); Account number: Original Account algam# 21cn.com (both the ' # ' replaces the original ' @ ' symbol), the password is: the original account password.

QQ can use Agent?
One time the author's classmate in QQ said: "How did you run to Shenzhen, you are not in Shanghai?" "In fact, I know this guy love to show off, not just installed a can see the QQ version of IP, now there are a few people use QQ is not to see IP." QQ Use agent can hide real IP, this can avoid some unnecessary harassment. QQ members can be able to use the HTTP proxy function, but not members can only use the socks agent. Some companies can only surf the Internet browsing can not use QQ, mainly closed the socks port, to avoid employees to work with QQ chat. In fact, there are ways to solve this situation. First download a socksonline software, is the ordinary HTTP proxy conversion to "omnipotent" SOCKS5 agent tool, Socksonline Agent is the use of Commonline online communication capabilities, socks agent transfer. Socksonline proxy use is very simple, as long as the client application of the SOCKS5 proxy set to the Socksonline address, the client will be normal use.

Using proxies in ICQ
Suppose you have a SOCKS5 proxy server, for example: 202.96.58.241, then in the OICQ system menu ==> Preferences ==> Connection, select "I under the firewall or proxy" ==> Click "Firewall Settings" ==> Select I use the SOCKS5 proxy Server "==> next ==〉 fill in the proxy's address ==> port number in the SOCKS5 (firewall) host address (typically 1080), and if you are unsure whether the proxy server is available, press" Check my firewall/proxy settings. ==> click "Finish".

Using proxies in ICQ2000
Icq==>preferences==>connections==>firewall==>proxies/firewall==> Select Proxy Server type SOCKS4 or SOCKS5 or HTTPS = => the host address and Port ==> in the Proxy Server page and finally do not forget to choose Use Proxy to resolve hostnames. Note: No test, but according to some netizens said at the time of installation if not using a proxy server, later use may not use the proxy server ICQ.

Use Agent on OICQ
Suppose you have a SOCKS5 proxy server, for example: 202.96.58.241, then in the OICQ system menu ==> system parameters ==> Network settings, in front of the proxy Socks5 firewall to tick ==> Insert the address of the agent in the firewall address = = > Port number to fill in the SOCKS5 port number (typically 1080), if you are unsure whether the proxy server is available, you can test by checking the test button on the edge of the user's password.

Use FTP proxy server (upload/download document)
1, the General FTP software settings. Server bar: Proxy server address, account for: account @ Original FTP server address, Password: The original account password. Use the FTP proxy in cute FTP as an example. Menu bar "FPT" ==〉 "SETTINGS" ==〉 "Options" ==〉 "FIRE wall==〉host: Proxy server address ==〉port:21==〉type:useruser@site==〉 select" Enable Firewall ... "
2, cute FTP use of SOCKS proxy server. Take cute FTP4.0 as an example:edit==>settings...==>connection==>socks==> select "Socks4" or "SOCKS5" ==> Fill in the address of the SOCKS4 or SOCKS5 proxy server next to the host (in view of SOCKS5 is very tight, and unstable, please use SOCKS4 for good) ==> choose "Firewall" to "Enable Fire ac ..." The check box next to the hook is removed. ==> Click OK. Now you can use the SOCKS4 Proxy server to upload the homepage. (Although most socks agents can upload the home page, but some socks agents do not allow the same IP repeat join, may not upload, when this happens, please change a socks agent)

Use a proxy server to play games
Boring time like to the public cards, units have two computers (the same IP), because the public has a ban on the same IP players at the same table options, so play when a no agent, a socks agent, or use SOCKSCAP32, this kind of game is basically a victorious, hehe. Another way is to use a computer to play, with another computer through the agent to peek at the opponent's chess. These two methods are also suitable for friends in the Internet café. If you see a person called the author in the audience do not play with him, or you will die very miserably, the same method can also be in the Chinese game Center, such as the use of game sites. Run the "Network game World" ==> Click "Set proxy Server" ==〉 choose to use the SOCKS4 or SOCKS5 agent (because the SOCKS5 agent is very scarce, suggest playing games when using SOCKS4 agent) ==> in the "Proxy server address" Socks Proxy server address ==> port default 1080==> do not forget to select the check box "join the Internet through a proxy server." ==> "OK" ==> the IP address of the game server in "address" (if you do not know its IP address, take Shanghai branch as an example, you can copy the address sh.ourgame.com.) Then open "Start Menu" under the Msdos way to type "ping sh.ourgame.com", he will return the IP address ==> last click "Connection"

Chat on IRC using socks agent
In the mIRC menu "file" ==〉 "option" ==〉 "Connection" ==> "Firewall" ==> Select "Use Proxy Server" ==> choose "Socks4" or "SOCKS5" ==> in "host" To fill in the SOCKS4 or SOCKS5 proxy server IP address ==> port with 1080==> to determine

Use SOCKS5 agent in V2 voice chat software
System Settings ==> "Network" ==> "Connection mode" select "I am using a proxy server that supports the SOCKS protocol" ==> Proxy Server (proxy) ==> Select socks5==> Fill in the IP address and port of the SOCKS5 proxy server 1080==> "OK" ==> now you can use voice chat and call your friends.

Use Telnet proxy to access BBS in CTERM2000
File ==> Address Book ==> choose to go to the BBS or add their own new BBS station ==> will be placed in the "Address" column of the BBS address (such as: NetEase's bbs.nease.net) clip to the "Automatic Landing" column, The original place fills in the Telnet proxy server's IP address (for example: 203.93.37.248) ==> then it is best to add "\ n" to the "Auto login" field to indicate carriage return, You can also add other symbols and characters if you know what user name you need to type in when you enter. (You can see his help) ==> in order to facilitate, it is recommended to click the "Output to Document" button, the settings will be stored in the document to facilitate the use of ==> then you can press the "connection site." By the way: My impression of cterm2000 is very good, the use is very simple, it is recommended to use the BBS users.

Second-Class agent article

For the Education Network and the Science and technology network of Friends, download directly from abroad to pay high flow fees, or machines can not directly linked to go abroad, so to use foreign agents, you have to learn to use the level two agent. How to set up a secondary agent see the description article for "Httport". "Socks2http + sockscap" setting, see other proxy settings Web sites. One thing to note is that not all agents can be used as a first-level proxy, only the HTTP proxy that supports SSL. In one word: first-level agent with the free HTTP proxy for SSL, two agent with the download of foreign agents of the document!

Introduction to the Level two proxy settings in Httport
If you just want to use level two agents, this software is much more convenient than SOCKS2HTTP+SOCKSCAP32. As for the other functions of the httport, I slowly groping it, for this aspect of the inquiry, do not reply! Of course, there is a premise that you use the first level agent to support SSL, in fact, in the Socks2http agent also has this requirement. That's why some agents can't be used in socks2http. Take 202.120.25.36:8080 as an example, first in the proxy page will fill 202.120.25.36 in the hostname or IP address bar, do not forget to fill in the port. Check the authentication, fill in the username and password (free agent casually fill). User agent to select IE, using the SSL connection mode, the rest does not fill. The second level proxy is set in the Port mapping menu. "External HTTP Proxy" Below is the level two agent you want to use, such as 2.25.56.58:80. "Remote host" filled in 2.25.56.58, "Remote port" is 80, as for that "local port", such as 3128, then you set up an agent in IE localhost:3128. Click on the "Start" on the left of the line.

Httport Download: Http://202.38.64.10/~adamxc/zip/httport3.zip

HTTP proxy converted to SOCKS proxy
First, we recommend two software: Sockscap and Socks2http. Sockscap I think I don't have to say it, if you have socks agent, use this nature can achieve level two agent, but socks agent is not much. The socks2http is an HTTP proxy that simulates the SOCKS5 proxy. For example, use 202.38.64.4:8080 as socks agent, fill in your account number and password if you fill in the Socks2http setting. Click "Finish" again. When used, fill in the localhost, port 1080, in the SOCKS5 Agent section of the software you are using. So the nature you use is 202.38.64.4 's socks agent. or run Sockscap, in Socks proxy settings fill localhost, pay attention to only SOCKS5, can not do SOCKS4 agent. But the Socks Agent with HTTP emulation is limited to a few network software. HTTP browsing is no problem (note that IE4 does not support Sockacap), but telnet,ftp is not necessarily, as if only the software itself to support the socks agent. It is recommended that you use Sterm1.0 in Telnet and use ABSOLUTEFTP for FTP. (Note the need to use the two-level agent software, must be running in the Sockscap, you use the first level agent to be effective). With this way, the benefits can be many yo! Especially the heroes who use 64.4. Use it to telnet,ftp the previous described. When the education network that road broken, with 64.4 or can, in particular, can no longer have a few thread restrictions, there is nothing can not download MP3 and RM file restrictions, do not believe you try! It's just a shame you can't use this method to oicq!. I want to have this method, we no longer need to worry about what level two agent problem. Like if you use 64.4 analog into SOCKS5, according to the above method, and then use a domestic free agent, even go abroad, speed is not so-so, but your money will crash to the outflow less!

For some not out of school IP, only the school proxy friend, have to use level three agent. Set the level three agent will have to Httport +socks2http+ sockscap together. Search for agents available in the school, such as 202.120.25.36 (assuming), use the first level 202.120.25.36 in Httport, or apply for a domestic browsing server (note that you have to fill in your account number and password). The second level is set in the Httport "port mapping" => external HTTP proxy, using a free agent that supports SSL. Then use the proxy localhost in socks2http, and the port is the local port (202.120.25.36) You use in the "External HTTP proxy" above. The following is the use of Sockscap, in which to start IE, the agent can download the literature to the agent in IE to fill out the place.

Two-time Agent Advanced Chapter

In fact, two agent is two agents cascade, there are many proxy server is to support cascading, such as: WinProxy, Wingate, not our own agent, just use agents, so do not discuss this issue, (only discuss how to use agents, The problem of establishing an agent to see the description of Wingate and so on, very easy. First said to use a number of software, Sockscap, Httport, Mproxy, these several software can be easily found on the Internet, agent-cascade generally have HTTP proxy and socks agent for the basis of, commonly used agent-cascade is probably the following several ways:
1, the HTTP proxy between the cascading.
2, the socks between the agents of the Cascade.
3. Cascading of HTTP proxies and other proxies.
4, Socks agent and other agents of the cascade.
5, the tlenet between the agents of the Cascade.

Cascading between HTTP proxies
HTTP proxy cascade can be implemented in a number of ways, let me say the simple two, the simplest way is to use mproxy, it supports level three HTTP proxy cascade, support the input of the first level two proxy address and port can then use the local 127.0.0.1:888 as a proxy to access, The disadvantage of this method is not to support the authentication of HTTP proxy, the need to authenticate the HTTP proxy, another method to use Httport, in fact, this agent is very powerful, is now only used for the cascade between HTTP agents, open the Httport, Enter the address and port of the first level HTTP proxy on the proxy page, select Authentication if required, enter username and password, then go to Port Mapping page, click the Add button, appear in the list new mapping, and then in remote Host enter the second level of HTTP proxy address, Remote port input The second level of HTTP proxy port, local port input port, such as 3128, 8080 port, etc. You can use local 127.0.0.1:3128 as a proxy after the proxy page Point Start button, and it is important to note that the first level HTTP proxy must support SSL connections, otherwise the secondary HTTP proxy cannot be cascaded. (SSL refers to secure Sockets Layer, a set of Internet data security protocols developed by Netscape, with a current version of 3.0.) It has been widely used for identity authentication and encrypted data transmission between Web browsers and servers. It is important to note that although the content you are browsing is encrypted, the connection site is visible at the top of the proxy server. In addition, the URL and IP of the site are still visible on the proxy server. The agent to find SSL is very simple, you can use the software such as Aatools, you can also use the Flashgat to verify directly.

Need to add that, the above two times the agent can be used for others, because it is in the local all IP on the monitor, such as in your machine IP is 10.9.1.11, the local port is 888, others can access 10.9.0.11:888 as two times proxy use, So you can share your two times with others, the mproxy is not multiproxy,multiproxy is to do agent verification and scheduling.

Cascade between SOCKS agents
There are several ways to socks proxy cascading, often using sockscap to implement, in the Sockscap Setting dialog box, enter the SOCKS proxy address, port, if socks5 and user and password, Then add the software that can use the socks agent (free socks better!!) , such as IE, in the Internet option socks set two level socks proxy address and port, in the Sockscap run IE can use two times socks agent, like other FlashFXP, Sterm and leapftp in the same, Set up a level two socks agent on these software, then run in Sockscap can use two times socks agent, also can use Sksockserver to implement, this software supports the cascade of 256 level socks agent, itself can also act as SOCKS proxy Server to use, similar to Mproxy, just add all levels socks proxy address and port can, in addition Sockschain also do socks cascading tools.

Cascading of HTTP proxies and other agents
HTTP proxy with other proxy cascade, here with the above mentioned Httport, note that the first level of HTTP proxy must require SSL connection (must be SSL agent Ah, otherwise not!!) , enter the address and port of the HTTP proxy on the proxy page, and then add other agents to cascade on the port mapping page, such as the Telnet agent, and enter the address and port of the respective Telnet agent in the remote host and RemotePort, in the local Port input Local listening ports, such as 23, click on the proxy page start, so Telnet 127.0.0.1 23 is connected to two agents, and then enter the address and port to remote login, Cascade socks Agent is the same, in port Mapping the address, port, and local listening port (such as 1080) of the proxy two times, so that you can use 127.0.0.1:1080 as a two-time agent on other software, and other FTP, POP3 agents are the same as the two level agent and HTTP proxy.

Cascading of socks agents and other agents
Socks Agent with other agent Cascade, here is the Sockscap, as described above, in the Setting dialog box input SOCKS proxy address and port, and then add other need to use two agent software, such as Ie,oe and FLASHFXP software, As long as the Internet option to enter the second level of HTTP and FTP proxy address and port, in the Sockscap run IE can use the level two HTTP and FTP agent, the other software is the same, set up on the level two agent in the Sockscap run can use the level two agent.

Cascade between Tlenet Agents
In fact, the cascade between Telnet agent is very simple, the common Wingate Agent for example, when we telnet to the agent when the wingate> prompts, directly enter another Telnet agent address and Port can, is generally "IP port", some agents are "IP :p ort "(such as CSM proxy Server), the input can be connected to two times the agent, in two times the proxy input to Telnet login address on it.

The above introduces several common proxy's cascaded method, actually is the nimble use above Httport,
Sockscap, such as a few software, as long as proficient in the use of software, can play a lot of tricks, such as with other software use, as for foreign two times agent, HTTP agent can go to the homepage of Multiproxy to find, other agents can enter free on google Proxy HTTP socks to search, the latest software can go to the homepage of the software to obtain, and finally say, learn Httport software to use a great future, for those who only opened the HTTP agent, the other port was sealed by the people's Congress is useful, to everyone do not use these methods do bad things AH Proxy Server on the things you do record clearly, first find you things are not easy, just ... I just want to see a movie! ）

SOCKS4/5 Agent plus Sockscap
1, first find a domestic SOCKS4 or SOCKS5 agent, the reason is domestic, the main is to avoid international traffic. At the same time, the education network users should also pay attention to the different schools defined free flow of the IP section is different, in order to protect you from the huge flow fee, be sure to confirm the free socks agent is a freebie!
2, run sockscap-Files-settings-fill agent (distinguish between SOCKS4 and SOCKS5)
3, add: New-browse-you want to run the software (such as IE)------OK.

Remember, every time you run the software, it's only going to take effect from inside the SCOKSCAP!!!

Level Three Agent

With Httport + S2H + sockscap that is: In the Httport with the first level agent (note to fill in your account and password) the second level with SSL-enabled free agent, in the Httport "Port map---> External http Proxy" set. And then in the socks2http with the agent localhost port is you in the above "external HTTP proxy" in the local port you use the following steps is to use the Sockscap, in which to start IE, the agent can download the literature to IE to set up a proxy place to fill it.
