Installing

Before Installing

Open Shen is not ready to go out of the box. Before installing, understand you will need to self provide the following:

• An SSL certificate & private key for the host server
  • This isn't required if you are running Fiddler Classic to redirect traffic.
• Protobuffer definitions for the version of Yuan Shen you want to run
• Yuan Shen packet IDs for the version you want to run
• Dummy packet responses for the Yuan Shen version you want to run
  • These can be dumped from a tool like Iridium.

Prerequisites

• An SSL certificate & private key for the host server
• Protobuffer definitions for your Yuan Shen client
• Yuan Shen packet IDs for your client
• Dummy packet responses for your Yuan Shen client
• Access to your system's hosts file
  • You can avoid modifying the hosts file by using Fiddler to redirect traffic to the localhost.
• Port 443 and 80 and 22102 open (and forwarded if necessary) on the host server

Installation

To install Open Shen:

1. Download the latest version of Open Shen from GitHub Releases.
   1. Make sure you download the version for your operating system.
2. Place the downloaded executable in a directory on your host.
3. In the same directory, create the following directories and place the corresponding files in them.
   1. certs: Add your HTTPS certificate and private key to this directory.
   2. versions: Add a version config for your Yuan Shen client to this directory.
   3. protocol: Add the protobuffer definitions for your Yuan Shen client to this directory.
   4. packets/rawPackets: Add dummy packet responses for your Yuan Shen client to this directory.
4. Configure a version of Yuan Shen for the server to use.
   1. A guide to this can be found here.
5. Run Open Shen.

Connecting

With Open Shen running, use one of the following methods to connect.

System Hosts File (recommended)

Note: This method only works if you have access (usually root or administrator) to your system's hosts file.

On Windows

Run: notepad C:\Windows\System32\drivers\etc\hosts in an Administrator Command Prompt and add or remove the hosts block.

On macOS/Linux/UNIX-based Systems

Run: sudo vi /etc/hosts in a Terminal and add or remove the hosts block.

Using Open Shen's Configurator

Note: This method has not been completed. Come back to this later for a quick and easy way to configure your hosts file!
