Readers can expect a comprehensive overview of Shadowsocks, including its setup, configuration, and practical applications. We will also discuss the technical aspects that make it a preferred choice for many users seeking privacy and security. By the end of this guide, you will be equipped with the knowledge to effectively utilize Shadowsocks in your online activities.

How To Use ShadowsocksR To Bypass The Chinese Firewall

Shadowsocks is open-source software that hides or obfuscates internet connections. It is widely used in mainland China to circumvent Internet censorship. Created in 2012 by a Chinese programmer named “clowwindy,” multiple protocol implementations have emerged since its inception. This guide will explore ShadowsocksR (SSR), its technical features, types, and how to set it up effectively to bypass the Great Firewall of China.

Understanding ShadowsocksR

ShadowsocksR is an enhanced version of the original Shadowsocks protocol, designed to provide better obfuscation and security. It allows users to create a secure tunnel for their internet traffic, making it harder for censors to detect and block connections. This is particularly useful in regions with strict internet censorship, such as China.

Technical Features of ShadowsocksR

ShadowsocksR offers several technical features that enhance its usability and security. Below is a comparison table highlighting these features:

Types of ShadowsocksR

There are various types of ShadowsocksR clients and implementations available, each catering to different platforms and user needs. The following table summarizes the main types:

Setting Up ShadowsocksR

Setting up ShadowsocksR involves several steps, from acquiring a Virtual Private Server (VPS) to configuring the client. Below is a detailed guide on how to set it up effectively.

Step 1: Get a VPS

To start, you need to rent a VPS. Popular providers include Vultr and DigitalOcean. Choose a server location that is geographically close to you for better performance.

1. Rent a VPS from your chosen provider.
2. Select the server type (e.g., Debian 7 x64).
3. Choose a package that fits your budget (e.g., $2.50 for 500GB traffic).
4. Enable IPv6 for better connectivity.

Step 2: Install ShadowsocksR

Once you have your VPS, log in using an SSH client like PuTTY. Execute the following commands to install ShadowsocksR:

bash
wget --no-check-certificate https://raw.githubusercontent.com/teddysun/shadowsocks_install/master/shadowsocks-all.sh
chmod +x shadowsocks-all.sh
./shadowsocks-all.sh 2>&1 | tee shadowsocks-all.log

Follow the prompts to select ShadowsocksR, set a password, and choose a port.

Step 3: Edit the Configuration

After installation, you need to edit the configuration file. Use the following command:

bash
vi /etc/shadowsocks-r/config.json

Change the protocol and obfuscation settings:

json
"protocol": "auth_sha1_v4",
"obfs": "tls1.2_ticket_auth"

Save the changes and restart the ShadowsocksR service:

bash
/etc/init.d/shadowsocks-r restart

Step 4: Download the Client

Download the appropriate ShadowsocksR client for your device. Options include:
– ShadowsocksR for Windows
– ShadowsocksR for Android
– ShadowsocksR for Mac
– iOS Potatso Lite
– iOS Shadowrocket

Install the client and enter your server details, including IP, port, password, and protocol settings.

Step 5: Protect Your SSH Access

To secure your server from brute-force attacks, configure iptables:

bash
iptables -I INPUT -p tcp --dport 22 -i eth0 -m state --state NEW -m recent --set
iptables -I INPUT -p tcp --dport 22 -i eth0 -m state --state NEW -m recent --update --seconds 60 --hitcount 4 -j DROP

This will block IP addresses that attempt to log in more than three times per minute.

Conclusion

ShadowsocksR is a powerful tool for bypassing internet censorship, particularly in regions like China. By following the steps outlined in this guide, you can set up your own ShadowsocksR server and enjoy unrestricted internet access. Whether you are a casual user or a developer, ShadowsocksR provides a reliable solution for navigating the complexities of internet censorship.
