Tag: Shadowsocks

Installing and configuring Shadowsocks on an Ubuntu machine involves several steps, including updating the system, installing necessary dependencies, downloading and setting up Shadowsocks, and configuring it to run as a service. Here’s a step-by-step guide to help you through the process:

Step 1: Update the System

First, ensure your system is up to date:

sudo apt update
sudo apt upgrade -y

Step 2: Install Necessary Dependencies

Shadowsocks requires Python and pip (Python package manager). Install them with:

sudo apt install python3 python3-pip -y

Step 3: Install Shadowsocks

Use pip to install Shadowsocks:

sudo pip3 install shadowsocks

Step 4: Configure Shadowsocks

Create a configuration file for Shadowsocks. The default location for the configuration file is /etc/shadowsocks/config.json. You might need to create the directory first:

sudo mkdir -p /etc/shadowsocks

Then create the configuration file:

sudo nano /etc/shadowsocks/config.json

Here’s a sample configuration:

{
    "server": "0.0.0.0",
    "server_port": 8388,
    "local_address": "127.0.0.1",
    "local_port": 1080,
    "password": "your_password",
    "timeout": 300,
    "method": "aes-256-cfb",
    "fast_open": false
}

Replace "your_password" with a strong password. You can also adjust the "server_port" and "method" as needed.

Step 5: Run Shadowsocks

To start Shadowsocks manually, use the following command:

sudo ssserver -c /etc/shadowsocks/config.json

Step 6: Configure Shadowsocks to Run as a Service

To ensure Shadowsocks starts automatically on system boot, create a systemd service file:

sudo nano /etc/systemd/system/shadowsocks.service

Add the following content to the file:

[Unit]
Description=Shadowsocks Proxy Server
After=network.target

[Service]
ExecStart=/usr/local/bin/ssserver -c /etc/shadowsocks/config.json
Restart=on-failure

[Install]
WantedBy=multi-user.target

Save and close the file. Then, enable and start the Shadowsocks service:

sudo systemctl enable shadowsocks
sudo systemctl start shadowsocks

Step 7: Verify the Service

Check the status of the Shadowsocks service to ensure it is running correctly:

sudo systemctl status shadowsocks

If everything is set up correctly, the status should indicate that Shadowsocks is active and running.

Additional Configuration

For enhanced security and performance, consider configuring additional settings such as:

Firewall Rules: Allow the Shadowsocks server port through the firewall.

sudo ufw allow 8388/tcp
sudo ufw allow 8388/udp
sudo ufw enable

• Optimizations: Adjust TCP settings or use fast_open if your kernel supports it.

By following these steps, you should have a fully functional Shadowsocks server running on your Ubuntu machine.
