Obfuscated SSH Service - Server

This project sets up an SSH service with obfuscated SSH support. It uses Docker to containerize the service and provides an example of how to connect using a client with SSH obfuscation.

If you are looking for Obfuscated SSH Service - Client, go to https://github.com/teal33t/obfuscated-openssh-client

Getting Started

Prerequisites

• Docker and Docker Compose installed
• A basic understanding of SSH
• Installing Obfuscated OpenSSH on your client

Installation

1. Clone the repository:

   git clone https://github.com/teal33t/obfuscated-openssh-tunnel
   cd https://github.com/teal33t/obfuscated-openssh-tunnel

2. Build and start the container:

   docker-compose up --build -d

Configuration

• Ports:

  • Standard SSH port: 2223
  • Obfuscated SSH port: 8443

• Volumes:

  • ./sshd_config:/etc/ssh/sshd_config:ro - The SSH configuration file is mounted read-only from the host.

Connecting with an SSH Client

To connect to the obfuscated SSH service, you should install obfuscated-ssh on your client machine

apt-add-repository ppa:zinglau/obfuscated-openssh
apt-get update
apt-get install ssh

And for connecting:

ssh -p 8443 -o ObfuscateKeyword=123qwer -D 0.0.0.0:1080 sshuser@your-server-ip

• -p 8443: Specifies the port to connect to (obfuscated port)
• -o ObfuscateKeyword=123qwer: Uses the obfuscation keyword configured in sshd_config, change it use a secure phrase.
• -D 0.0.0.0:1080: Sets up a SOCKS proxy on port 1080
• sshuser@your-server-ip: Connects to the SSH service as sshuser

Troubleshooting

• Ensure Docker is running.
• Verify that ports 2223 and 8443 are open and not used by other services.
• Check the logs for any errors:

  docker logs <container-id>
