Shadowsocks with .pac (ss-pac)

A simple, home-ready solution for traffic routing using the Shadowsocks protocol. If you don't want to switch proxies just to access certain sites, this solution can help you.

You can configure the list of sites that you want to open through the proxy. The server returns a .pac file which you can use in your system settings.

Getting starting

Prerequisites: You need to have Docker and Docker Compose installed. If you are not familiar with these tools, please refer to this link.

Step-by-Step Installation

1. Install Docker and Docker Compose.
2. Fork the repository or download it to your PC.
3. Configure the ./outline/config.json file with your specific parameters. Explanation of this file here
4. Add sites that you want to open through the proxy:
   1. Open the file./pac-server/localproxy.pac
   2. Find the line const hosts = [ "place urls here" ]
   3. Add the URLs you need. For example, if you want add google.com and bing.com the hosts variable should look like this: const hosts = ["google.com", "bing.com"];
5. Run the following command in the terminal: docker compose up -d.
