What kind of scientific way should I choose to surf the Internet?

Should I buy a VPN, an airport, or a VPS self-built ladder?

Which way is more stable, safer and simpler to use?

That “wall” is actually short for the Great Firewall

The full English name is Great Firewall

There are also friends who call it Kung Fu Net or GFW

GFW is the abbreviation of Great Firewall

That “wall” is also aimed at the Internet in mainland China

A general term for the censorship system created

This review system started in 1998

When the user visits the website or the server’s IP in the Great Wall firewall list

The wall will block the communication with the server, and the user will not be able to access the target website

For example, Google, YouTube, etc. Here I want to tell everyone

Gfw list we often say

In fact, it is a blacklist, as long as it is a URL/domain name in the blacklist

Or the server IP, which cannot be accessed normally in Mainland China

In fact, this blacklist is a blacklist in the censorship system we are talking about

Its purpose is to filter out content that does not meet national regulations

We often talk about supporting the wall or surfing the Internet scientifically

Is to use special methods or tools

An act of browsing or using a website in GFW

Here, we do not discuss the necessity and pros and cons of its existence, etc.

I just want to “understand” it with everyone and learn how to “bypass” it

Or to reduce its impact on our access to information

So as to obtain valuable information to oneself and improve one’s own cognition

To help us better understand “over the wall”

Let’s first understand what is a principle of basic web browsing

Actually when we visit a website

Actually visit this website

Data of the website on the corresponding IP address server

To put it simply, for example, we entered baidu.com on the browser

In fact, we visit the baidu.com domain name and the website data on the (corresponding) IP server

The ladders, blog sites, and personal websites we usually build

DNS domain name resolution for corporate website

The purpose is to point the domain name to the IP address of this server

As long as we enter the visited website or domain name in the browser after the request

The DNS server of the local broadband operator

Will resolve the server IP corresponding to this domain name

And visit the directory where website data is stored

Then the data will be transferred to each other

Then we can open this website

In other words, visit the data of the website on this server

You may also be curious why we don’t directly

Enter the IP of the server to access this website data

Instead, enter this website or domain name to visit

That’s because the IP address numbers are too complicated

Websites and domain names are easier to remember than IP addresses

So, the shorter the domain name or website, the higher its value

If you want to know more details or information

You can click to watch the video tutorial of this issue of “Cheese”

Because of the existence of the “wall”, in fact, the operator’s DNS server

After receiving our visit request

In fact, it has to go through the GFW, which is this wall

And then go to the target website

When our target website or service is in the GFW List

It’s also the blacklist we just mentioned

At this time, the “wall” will block the communication with the target server

Cause us to be unable to access the website or use the service

We often say “over the wall”

In fact, it is through various technical means to bypass the active detection or blocking of the wall

So that we can normally or use the websites or services in the gfw list

Simply put, it is the VPN we enabled locally

Or after the node added in the client, it came to take over

At this point we only need to enter youtube.com or google.com in the browser

Local computer, it will disguise the request as

To visit our “source” server in a foreign country

Or the open source (program/node) that has been deployed on the VPS

Because the IP of the server or the domain name we use here

It is not in the gfw list, so the “wall” will release (access) requests

The foreign “source” server, after receiving the communication request

He will go to check, what to check?

Verify the node configuration information in the client or VPN

Server address, password, encryption method, port, etc. deployed with the server

Determine if they are the same

If the confirmation is correct

The server (review) access request is reasonable, and then I go to visit the target website

For example, this is the youtube.com just entered

Then after visiting the website directory corresponding to YouTube

And then send the data back to our computer

This time we can bypass the wall

And can access blocked websites or services normally

It’s the tubing we just entered or Google or XXXhub

Of course, is it against the law after all over the wall?

If you mean, the following types of over-the-walls must be “yes”

Next, let’s take a look again, what is a VPN?

VPN, its full name is virtual private network

Because of my English pronunciation (bad), I won’t read it here

In fact, it is a kind of encrypted communication technology

At the beginning of the design, it was not born for overcoming the wall

It is only used for data transmission security and network anonymity

Most of the application scenarios are when we connect to free public WiFi

Or when using a home network, to hide your IP address

At the same time, make sure that your sensitive information will not be leaked

For example, your browsing activity, password, email information and other information

In fact, from the perspective of overcoming the wall, VPN technology has many problems (spoken mistakes)

The most serious problem is that its traffic characteristics are too obvious

At present, the wall has been able to accurately identify most of

(Use) the flow characteristics of VPN technology and block it (spoken error)

So, VPN is basically out of date

Especially in the special sensitive period

In the last few days, most VPN service providers have stopped their services

In fact, there are also some VPN providers

For the convenience of promotion, it named the client or APP XXXVPN

In fact, it uses v2ray

Nodes built by open source programs such as shadowsocoks and shadowsocoksR

Also because of their high prices and easy use

VPN has become the way most of the small partners first come into contact with the wall

Of course also myself

Slowly, some small partners understand VPN as a general term for “wall circumvention tools”

The so-called airport does not refer to the airport where we go on a daily flight.

But some special service providers or platforms that provide private access to the Internet

At first because of the service provider or platform

All protocols used are shadowsocoks and shadowsocoksR

The logo of the client used is the pattern of a paper airplane

Therefore, the airport has become a collective term for service providers that provide scientific Internet access or circumvent the wall.

Because airport service providers also need larger operating costs

So, most airports will set up different package services

Corresponding to different service contents

For example, the flow limit used, whether to unlock the streaming media node

Whether it is a transit line, IPLC, IEPL line, etc.

Is to distinguish these (services)

In layman’s terms, the airport is similar to the mobile, China Unicom, and telecommunications operators we use.

Users will be based on their needs and budget

Choose different operators and corresponding service packages

In fact, we are talking about self-built ladders or VPS building nodes

It is a program to deploy open source network tools on foreign servers

For example, Shadowsocks, V2Ray, Trojan, Xray

And generate the corresponding server address, port, password, encryption method and other configuration information

This is why in the video we demonstrated

There are always these configuration information out, that’s why

Then, our users install a client that supports open source programs on the computer

Enter the configuration information of the server to connect

And create a local proxy

Then the software on the server side and the computer client side will require each other

Provide server address, password, encryption method, etc.

Wait for the two parties to verify the agreement before they can connect successfully, so as to realize “Proxy Internet access”

For more information, please refer to the chapter on principle of overturning the wall

We often talk about Xray, shadowsocks, v2ray, trojan, etc.

They are the program names of open source network tools

Are developed in different programming languages

The main realization (method) is to use certain licenses

I will not give an overview one by one here

Interested friends can find out

The server side we are talking about is actually our VPS

We only need to buy a VPS service provider to mention VPS

Common VPS service providers, such as Bricklayer, Vultr or Google Cloud, etc.

The client is what we often call Qv2ray, Clash, v2rayN

v2rayNG, Shadowrocket, etc., even soft routing system plug-in passwall

Or SSR plus, Openclash

Hello World plug-in, etc., can be used as this client

That agreement is actually what we often call vmess, vless, trojan, shadowsocks

They use different encrypted transmission protocols to encrypt data

In order to avoid the sniffing of the “wall” reasonably

Before that, I will give you a principle

No matter you use or choose any scientific method or way of surfing the Internet

Don’t touch or comment on sensitive topics

In order to avoid risks to the greatest extent

Because most of the friends can’t avoid

Or block input method or anti-virus software

Or the airport collects your personal data or information

Faced with so many airports or so many agreements, how should I choose?

Here I share my personal opinion, there are 5 points in total

You can also refer to this table

I’ll talk about this form later

First, you must take 5 minutes to write about your needs for scientific Internet access

Or the budget is to look at xxxxhub, youtube

Facebook or tikkok, netflix

According to my own needs

Then go to choose a different airport package or VPS server

If you have these requirements (above), VPN recommends that you not consider it.

Second, if your budget is sufficient, try to choose an old airport

There is also a website dedicated to evaluating airports, called Poisons website for short.

Everyone can click to watch

There are many reviews of these airports on this website

You can refer to it

The third one, no matter you buy any airport packages or services

I suggest you buy it for a month and 免费翻墙软件 try it

Even if you try it for the first month

The overall speed or service is very ok

I don’t recommend your package here. A single renewal lasts more than three months.

After all, no one knows what the future development of the airport will look like

Fourth, we must be alert to large-scale promotions at the airport

Because airports have fixed operating costs

It is impossible to reduce the package cost without special circumstances to reduce your own profits

After all, ordinary airport owners have to make profits or make money

In order to provide quality service and stable lines

An airport that blindly makes profits and reduces its own profits

Everyone carefully considers and carefully tastes

Point 5, if your budget is sufficient

You see, I mentioned another budget here

In fact, budget is the biggest factor that affects your choice

It is recommended to buy more than two airports, one of which can be the main force can be shared

In addition, it can be used as a backup in case of special circumstances.

For example, recently

Actually the airport I have on hand can be used now

Both main and backup are available

Let me tell you about it

There will be bad airport service providers or airport owners who will choose to run away at a certain time

Then change the website or name and re-operate

This is why I suggest a renewal period for a single package in the third point.

Don’t exceed three months, this is the root cause, everyone should pay attention!

Here I briefly talk about this form

First, if the VPN budget is acceptable to you (spoken language)

Then it can stand its slower speed

It has the disadvantage that it cannot be used in sensitive periods, it is recommended to use VPN

If your budget for a month can be less than 60 yuan

I suggest you go directly to the airport

Because the airport has stable and good routes

Although it has traffic restrictions, it supports more services

But it’s easy to get started

Because of it, after all, it will involve some client settings

There are also some client-side tutorials in my channel

If you are interested, you can check it out

The third, self-built ladder is for some small partners

They actually have a certain amount of hands-on ability, they can buy a VPS (build a ladder)

However, TA has several disadvantages

The first one is that it is difficult to get started

Because you are going to register a domain name\buy a VPS\you have to run the script

Second, TA takes more time, what does it mean?

If you bought a VPS and built a good node, suddenly this node can’t be used

You have to (re)build the node again, and so on

You spend too much time on a scientific online behavior

Don’t spend time if you can spend money to solve things

This is my opinion

For the computer client, I suggest you use Qv2ray

Here you can click to jump

If you want to use VPS to build a ladder

Suggest (use) Xray open source program

Third, if you still think the airport side is more suitable for your needs

You can also take a look at the masonry mover’s official airport just my socks

You can click to understand

Of course, before that, I still want to emphasize one point for everyone

Just my socks airport, it has a shortcoming, it will be cut off

The specific situation, the picture (below) has been written very clearly

If you can accept the cut-off situation, you can try it

(After all, it) supports 7 days no reason to refund
