Shadowsocks

Available in Classic

Shadowsocks is a service platform to set up a Virtual Private Network (VPN) utilizing the Shadowsocks server while using Linux as an OS. It is automatically configured on NAVER Cloud Platform's Compute infrastructure service and can be instantly put into service through a configuration process with only a few steps.

The advantages of using Shadowsocks are as follows:

• You can use a stable VPN service utilizing the infrastructure services of NAVER Cloud Platform.
• You can select a server image and specifications to automatically install and use the Shadowsocks server.

Creating and accessing server

The method for creating and accessing the server is the same as creating a regular server on NAVER Cloud Platform. The following are detailed procedures and reference guides:

Using server

When the server is created, the Shadowsocks service is automatically installed, so you can use the service immediately.
Check if the service is installed successfully using the following methods, and then edit the configuration file, if necessary.

• Check Shadowsocks service process

root@shdscks:~# ps -ef | grep ss-server
shadows+  1004     1  0 11:28 ?        00:00:00 /usr/local/bin/ss-server -c /etc/shadowsocks/shadowsocks.json -a shadowsocks -v start

• Check Shadowsocks service port status

root@shdscks:~# netstat -na | grep 8388
tcp        0      0 0.0.0.0:8388            0.0.0.0:*               LISTEN

While connected to the server, you can run the following commands if necessary.

• Stop service: systemctl stop shadowsocks
• Run service: systemctl start shadowsocks
• Check and edit the content of the Shadowsocks configuration file: vi /etc/shadowsocks/shadowsocks.json
  • Description of configuration file item and how to edit it
    | Item | Description |
    | :-- | :--- |
    | server | The default value is 0.0.0.0
    Enter the public IP address of the server |
    | server_port | The default value is 8388 |
    | password | Access password
    Set a highly secure password |
    | timeout | Access timeout time |
    | method | Encryption method
    Using an AEAD algorithm is recommended (see AEAD ciphers) |
    | fast_open | Reduce wait time when starting
    Set true or false |

Using Shadowsocks Client

To use the service, you need to install Shadowsocks Client and register the created Shadowsocks server.
Install a client suitable for the OS you are using. This guide is based on the Outline application.
