I believe that many students are worried about the high traffic costs of the campus network. The school is also constantly looking for ways to save traffic.
The school Internet is very painful, 3 gigabytes of free traffic per month, this is the first time to encounter the flow rate of the broadband network, so I found some ways to free Internet access through ipv6, now share it.
Note: These methods are implemented by ipv6 and must have ipv6 access.
First of all, how to confirm whether you can use ipv6.Open the network connection, open the network you use, you can see the status of the ipv6 connection, display the Internet, that is available, then you can continue to look down. If it is not available, give up, Sao Nian, find other ways to go.
Here to remind you, like the dormitory building of Xidian, you need to dial the broadband to connect to ipv6, so go to dial first. It should be noted that the general campus network is to calculate ipv4 traffic, after dialing, that is to say, your campus network has been logged in, you can go traffic, so pay attention to turn off ipv4.
Also open the network connection, find the broadband dial-up, as shown above, click on the properties, remove the checkmark in front of the ipv4 protocol, ok your campus network will not go traffic.
1. Campus v6 https://xiaoyuanv6.com/
This is a VPN using ShadowSocks, 3G traffic per month, can be checked in daily, the speed is OK, and it can be over the wall.
Need to download ShadowSocks, the tutorial is relatively simple, you can look at it.
2, immediately six http://MsDownload/
This is simpler than the campus v6, you only need to download the client registration to use, no need to configure anything. However, the speed of the network is unstable, the number of people used in the morning is small, the speed is very fast, you can get things down; the number of people who use it is very good, but it is enough to use the brushing webpage to find the information.
3, six speed dial http://
Similar to the current six, the same is true for use. Open the client to log in. It is better than the immediate six. The speed is very stable, but the member is limited to 50K per second. Very stable, can play LOL, very recommended.
In addition, you can also directly use ipv6 on google, youtube or something, you only need to ipv6 connection on the campus network, open these pages on the line, are not going to traffic, you can rest assured.
After finding a variety of solutions, I found that the scheme of renting a VPS to build a shadowsocks server is most operational.
ImplementationThis solution is to achieve the purpose of saving traffic by using the campus network to not charge IPv6 traffic. However, because there are too few websites supporting IPv6, it is impossible to directly access the website by IPv6. So we need to rely on an intermediary to help, this is the VPS (virtual server). It should be noted that this VPS needs to support IPv6, that is, the VPS service provider can allocate a public IPv6 address. The VPS accesses it with its own IPv4 address, and then communicates with the local machine through IPv6 (this part does not count traffic), which is actually equivalent to the traffic statistics being passed on to the VPS, instead of calculating the traffic to the campus network.
In order to be able to connect to the VPS from the local host, we also need to use the shadowsocks tool. The specific principle of shadowsocks is not covered here. Interested friends can go to the wiki to understand.
Tool preparationVPS
There are many service providers in the market to provide virtual server rental. Considering the cost performance, IPv6 and other factors, I will introduce the more popular VPS. The durian can purchase according to their own needs.
Recommended to move bricklayer "Bandwagonhost"
Official website address: Click to enter
This is a VPS strongly recommended by the wolf. In addition to its low price, it also supports a one-click configuration of the shadowsocks server. It is extremely convenient to operate and is suitable for people who are not familiar with Linux. However, the mover has only the US node, which cannot be satisfied for users with multiple nodes. At the same time, the US node also means a certain delay.
Pros: 1. The price is low, even if it is canceled the 3.99 knife annual fee package, it is still the cheapest of the three.
2. Support one-click configuration and reloading for beginners. It’s very cool to play after it’s broken.
3. Assign 3 IPv6 addresses at a time. (Some servers do not provide IPv6, you must see it when you purchase)
4. Support Alipay (it is simply a big death)
Cons:1. Only US nodes, poor diversity, high latency
2. One-click configuration omits a lot of details, which is not conducive to future configuration (I don't know where the configuration file is placed until now)
2. shadowsocks
Shadowsocks is a network transmission software based on the socks5 protocol communication. After deploying the ss server and ss client on the VPS and your own computer, you can use the agent network. At that time, your computer will use the VPS IP address for external network access.
Shadowsocks server version and client version. When it comes to pointing out, for the well-known reasons, the client of shadowsocks is not easy to find. Here are two methods for readers' reference:
1. Although the original author's ss project has been emptied, github also has other versions retained by the developer, including the ss client: https://github.com/shadowsocks/shadowsocks-windows/releases. This version of the ss client is developed for Windows and is still under maintenance. I am also using this client. However, it should be noted that the download of github is also mysterious. There is a high probability that the download will fail. A more reliable method is to give the project to the local.
2. The download address of the original client of ss is retained on the one-click installation interface of the bricklayer. After the actual measurement can still be downloaded, but the version number is still at 2.x, a bit old. If the win10 user may have problems connecting, it is recommended to find active projects on github.
The tools are all finished, let's talk about the installation and configuration process in detail. Because the configuration of the moving bricklayer is relatively simple, I will first introduce the whole process of moving the bricklayer from purchasing, installing the OS and installing the ss server. The installation configuration of digitalocean will be updated slowly in the future.
