SSR over the wall tutorial

0 Comments | 2024年05月28日

This article discusses SSR over the wall, compares SSR node types including free SSR nodes, SSR subscriptions, and SSR account purchases, I’ll recommend good SSR airports, teach you how to set up SSR servers with services such as Google, Tile Movers, Vultr, and where to download SSR clients.

To read this article, it may require users to have a bit of technical knowledge, if you are a non-technical user, you should consider commercial airports with higher usability: JustMySocks, or directly use a VPN to flip the wall, such as ExpressVPN, Astrill VPN. there are already mature commercial based SSR-like software on the market, such as PandaVPN, although the name is called VPN, actually using SSR-like proxy technology. In fact, the use of SSR-like proxy technology, you want to use SSR to flip the wall, is not the same as have to go to the rack server, see why white users do not build their own SS R.

SSR Over the Wall Reminder

SSR isn’t perfect.

There are two biggest difficulties for ordinary people to use SSR for scientific Internet access, one is to find a reliable server, and the other is to configure the client. Many SSR users are not willing to spend money on commercial SSR nodes, and the result of using free servers is that they have to manually update them every few days, because free servers are what everyone wants to use, so the free nodes are always quickly overloaded and lose their practical value. Even some popular websites claiming to be free high-speed SSRs are not able to consistently provide high-quality SSR nodes. Another problem encountered by non-technical users is the client configuration, and the mature VPN client is different, the current ShadowSocksR client still needs a little manual configuration, in the degree of ease of use is still a little bit worse, the ordinary user mistakenly configured successfully, but if you find that the configuration can not be used, it will be a big headache. ssr and vpn are the same, they are not perfect.

Don’t share SSRs on the public network

Definitely don’t do SSR sharing on the domestic public network as a big favor, especially on servers you’ve set up yourself, there have been individuals who have been invited to tea and paid fines because of this, men have been convicted of selling SS, and the author of the teaser base has been prosecuted.The open source and technologically more flexible nature of the server-side of SSR makes it a better proliferator than VPNs, but it also makes it more dangerous because of it. Don’t offer anything SSR download related on your domestic network, whether it’s a node address, a subscription address or an SSR script, remember!

Use free SSR nodes with caution

If you want to use SSR to flip the wall more stably in the long run, it’s better not to use free SSR. It’s not that free SSR nodes can’t be used, but most of them can’t be used for a long time, and their connectivity and speed can’t be guaranteed. Because these node IP addresses are shared on public websites, a lot of people use them, and the IPs are blocked very quickly, so they often need to be updated manually frequently, and many free SSR airports don’t offer subscriptions, which makes it very troublesome to update them manually frequently.

Understand the limitations of self-build

Build your own SSR has special advantages, for example, in certain sensitive periods often because of the privacy of the self-built server and traffic characteristics of the small instead of being walled — at this time the vast majority of well-known wall-flipping tools will basically rest. However, self-built servers also have great limitations, I do not build their own VPN or SSR in the white said, here to repeat. Self-built server single IP is difficult to fight against the firewall for a long time, even if now lucky, the probability of being blocked in the future is still very high, although the VPS vendors are providing IP replacement services, but the IP replacement is not unlimited, at most, you can change the IP for free once, and then you have to pay for it, not only spend money but also time consuming, even if the change of the IP is good, it is still a single IP to go through the wall, and the trouble in the future is not much smaller.

SSR node type

Free SSR nodes (manual update)

Free SSR nodes are shared everywhere on the internet, especially in the coder’s circle, sometimes when you open some personal blogs, there are SSR related pages in the menu. Unfortunately, basically when you see these pages, the free SSR nodes shared in them are not available anymore, this is the reason why we don’t recommend to use the SSR free nodes, it’s not easy to find the ones that are available, and most of the ones that are available are not available. This is the reason we don’t recommend using SSR free nodes. Even the ones that do work at the time lose availability due to overcrowded servers.

Slightly better free SSR airports are also available, such as, which offers nodes in Tokyo and Los Angeles server rooms, updated weekly. We have measured these free nodes, are available, only the speed is not very ideal, such as the oil pipe thumbnail loading and video caching is slow (mostly because of the free SSR nodes used by a large number of people’s sake), but used to Google search, gmail, on a twitter, facebook enough. It’s a pity that the website doesn’t provide SSR subscription address, so it’s a bit troublesome to update SSR nodes manually every week. There are also SSR widgets, but these sites are basically inaccessible in China.

Subscribing to an address with SSR (auto-update) recommended various subscription source address, did not carefully test the availability of the comments, these free and public nodes fail very quickly. ssr subscription address is active in many stations and telegraph group, if you can access Google, search “ssr subscription” can be found in a pile of searches, such as Free SSR node subscription source updates, SSR free node subscription address, page. The author of this article does not have the time to confirm that the subscription address is available (the subscription address is also easy to be walled), subscribe to the updated SSR nodes can not be used, but according to my past experience, can be used probably not more than half.

Buy SSR Account, SSR Airport Recommendation

I think this is by far the most reliable way to get SSR nodes: buy SSR accounts outright and use paid SSR airports.

More and more people are beginning to realize that opening SSR airports is a profitable business, and in fact it is also the case that a large number of vendors have entered this market in the past two years to start a fight, and at present there are estimated to be a few hundred SSR airports, both well-known and unknown, and the vast majority of them are operated by Chinese, all of them provide Chinese language services, and some of them have even completed their registration and operation in China (I don’t know how they do it), and the paid SSR accounts are becoming cheaper and cheaper under the saturated competition. Saturated competition is becoming cheaper and cheaper, because vendors set up servers can be efficiently reused, so the cost of individual users to buy SSR nodes is often lower than the cost of individuals to buy a separate VPS to build their own. For example, JustMySocks, a subsidiary of Tile Movers, has long had airports for around 100 RMB a year.

In this article, we will continue to recommend inexpensive SSR airports.

Build your own SSR node

Installation of SSR server side

I assume that people who use SSR to climb over the wall are technically savvy, so I won’t ramble on about how to install SSR server-side, I recommend the installation method from the SSR official website, I think it’s safer, there are a lot of one-click installation scripts and their variants popular on the Internet, of course these scripts are very useful, but because they need ROOT privileges to run, I don’t have time to review them one by one to check their safety. I don’t have the time to review each of these scripts for safety, so I don’t recommend them for now. If you don’t mind, you can search for “SSR one-click installer”. The operation method is similar, first SSH to the server, and then execute the command line sequence, the most used host to build SSR is to move tile work, Vultr.

SSR Client

The client is divided into several versions according to different platforms. Currently, the available platforms of SSR client are: router version, Windows version, Android version, IOS version, MAC version, which basically cover our daily use environment.

Windows (computer)

Windows SSR Client Download

SSR download is complete, unzip, and then run ShadowsocksR-dotnet2.0.exe or ShadowsocksR-dotnet4.0.exe can be. SSR Windows client run, need to support the .net environment, generally speaking, Win7 or above system can run directly. If you get an error when running SSR, you need to install Microsoft .NET Framework 4 first.


Android SSR Client Download

The original SSR mobile client, for various reasons, has stopped updating. The latest Android mobile client, which was updated by the developer based on the original version, the author added an extra R to the name, called ShadowsocksRR or SSRR, which is actually still SSR, and the latest version is currently 3.5.4.


iOS SSR client download (must be opened in Safari)

Open Safari on your iOS device, open this page, click the link above and follow the prompts to complete the installation of ShadowRocket (Little Rocket), and for those readers who are able to, the download link on the App Store is here.


Mac SSR Client Download

SSR MAC client is mainly used for Apple computer settings, such as iMAC, Macbook. there are two main versions of Shadowsocks MAC client: ShadowsocksX and ShadowsocksX-NG, of which ShadowsocksX-NG is the latest version of ShadowsocksX . Currently these two versions only support SS original version, and do not support SSR obfuscation. The ShadowsocksR MAC client, however, is derived from the above two versions and has multiple R’s after its name: ShadowsocksX-R and Shadowsocks-NG-R. The versions with R’s support SSR obfuscation. It is currently more recommended to install the Shadowsocks-NG-R version.

router (computing)

Router SSR Client Download, SSR-PLUS

This type of tool has not been used much by the author, so readers are referred to the outbound article.

Why novice users should not set up their own VPNs or SSRs

If you’re a techie who doesn’t even know what Linux is, it’s better not to set up your own, I think a VPN that can be installed for dummies is more suitable for you, if so, see China VPN Recommendations.

It’s only a matter of time before single node IPs are blocked

IP (or port) is blocked is a common thing. GWF’s DPI (DEEP PACKET INSPECTION) has a very strong traffic identification ability, once the IP is detected is blocked, their own set up VPN or SSR VPS immediately scrapped. Your tool is evolutionary, the wall’s algorithm is also evolutionary, and evolution is fast, open source tools have a few people to maintain, the wall has how many people to maintain, long-term which prevails?

Costs associated with changing IPs

It is true that there are VPS that you can change IP, even for free, but how do you know that the new IP is usable, at least you have to spend time to test it, right? Even if it works, how do you know that the new IP will not be blocked? Even if it works, how do you know that the new IP is not blocked? What do you do if the new IP is blocked, and then change the IP? In fact, the vast majority of VPS vendors can change IP for free, but only the second IP for free, the third and later IP have to pay for it.

Configuration and upgrades are a burden

Maybe you think the big deal is to change the host, can be, but set up VPN and SSR (or any other open source wall tools) need some manual configuration, you have more time, willing to go back and forth with your own, software upgrades also need to take some time, you just want a tool to science Internet, the results of their own half a day of tossing the tool, the time to spend down the cost-effective?

Characteristic flows and externalities

Moreover, the popular self-shelf VPS often have a large number of users like you, IP is a circular allocation, the new VPS to get the IP may be used by others to be walled, the more users of a server room self-shelf tool, the more obvious the traffic characteristics, the greater the probability of a normal IP is blocked, the extreme case is that the entire IP address segment is blocked, how do you change the IP is useless.

The external effect is that, originally a foreign room can still be used to put a normal website and other normal applications, we all flock to set up a VPN or SSR, resulting in access to normal applications packet loss rate increases, the probability of being walled increased, the traffic over the wall of the traffic death of the normal traffic, a large piece of the IP lineup, a large piece of the website deceleration, you are not happy? You don’t do your own website, maybe you don’t care, but one day you or your friends want to use such a host to do something serious, and found that the foot can not be stretched into the following are all sludge and muddy water.

The line cannot be optimized

The VPN or SSR can not do line optimization, because the vast majority of users like to self-frame actually do not understand the technology, you think that the choice of a nearby server room, buy a cheap host, loaded with a VPN or SSR software, a few lines of command to get it done, stability and speed seems to be okay. Sometimes it is true, but this is because you are lucky, a few lines of command did not get it done users, either the IP can not, or with the use of the wall, for reasons mentioned earlier, there are also installed and found that the speed is very average, because you only choose the host, and can not be optimized for the line, and this is exactly the VPN vendors can do a good job of it, they will also be used in the VPS, but they are carefully selected. The same is the Singapore server room, you choose your own big deal when you choose a server room, the vendor to choose, but can be selected to optimize the line and host as much as possible, the vendor can even deploy their own physical servers to achieve the optimal line, you can not.

Why do so many people enjoy it?

There are rumors online that paid VPNs don’t work, but the webmaster of this site has always used paid VPNs, so how come they always work? If it doesn’t work, why did a certain foreign first-tier VPN vendor triple its mainland traffic in 2018?

Is it because you didn’t buy the official release at all, but “downloaded” the tool from an unofficial source just to get it for “free”? Or you didn’t configure it properly? Or do you have P2P downloads on every day? Either way, it’s absolute bullshit to say that paid VPNs don’t work.

I know that there are people who feel that paid VPN is too expensive, set up their own cheap, then we can calculate, a VPS at least a dozen dollars a month or to run into the IP is blocked, change the IP or change the server, will bring more costs, and the price of paid VPN a month is just a few tens of dollars, the price is really that big a difference?

Besides, paid VPNs offer zero manual configuration of the client, Android, iPhone, Windows, Mac can be installed for dummies, installed and ready to use, automatic updates, is not the cost of time much lower than setting up your own? Do the math yourself.

I’ve been using ExpressVPN + Lantern I’ve been using ExpressVPN + Lantern (Blue Lantern) for several years. I’ve been using it for several years now. I can switch to another one if one of them is not working well, so I can always go through the wall, no matter what device I use, even during the time of the year when I have a meeting, I’ve never encountered a situation where I can’t get online, but the big thing is that the speed is just a little bit slower than usual during that time. How much does it cost per year? Only a few hundred yuan, is it expensive?

A combination of paid tools like this is currently the only solution that guarantees long-term wall-flipping stability and speed, bar none. I know that new open-source software for my own setup is popping up all over the place, and I’ve never considered it. One, my solution was already good, and there’s no need to change it, and two, how long can we count on an open-source wall-flipping tool to be rock-solid?
