How to bypass internet filters (like Aeroplanes or airports) using Shadowsocks proxy

Everything

Here’s a quick setup guide to use Shadowsocks proxy with obfuscation so you can use unfiltered internet access in Airports or Aeroplanes, etc.

I’ll be using Ubuntu 22.04 for this

Mandatory system update

apt update && apt upgrade -y

Install Shadowsocks

apt install shadowsocks-libev -y

After the installation edit the configuration file

/etc/shadowsocks-libev/config.json

{
    "server": "0.0.0.0",
    "server_port": 443,
    "password": "USE_A_STRONG_PASSWORD_HERE_FROM_YOUR_PASSWORD_MANAGER",
    "timeout": 300,
    "method": "aes-256-gcm",
    "fast_open": true,
    "mode": "tcp_and_udp",
    "plugin": "obfs-server",
    "plugin_opts": "obfs=http"

}

Install obfuscation

apt install simple-obfs -y

Start and enable Shadowsocks proxy server

systemctl enable shadowsocks-libev
systemctl start shadowsocks-libev

Check if it is running (should say active (running))

# systemctl status shadowsocks-libev.service
* shadowsocks-libev.service - Shadowsocks-libev Default Server Service

You can then use a basic configuration in your Shadowsocks proxy client like this:

  1. Server IP: your server’s IP
  2. Port: 443
  3. Password: same as in config
  4. Encryption: aes-256-gcm (or whatever you set)

Please check Reddit, etc for a client that you can use as many can contain malware.

Example of one I am using right now on OSX is:
