What is a SlipStream server?

A SlipStream server is the backend component that enables secure VPN tunneling for SlipStream GUI clients. It acts as an encrypted tunnel endpoint, routing your traffic through a remote server to provide privacy and circumvent network restrictions. The server creates a SOCKS5 proxy endpoint that clients connect to through an encrypted tunnel, ensuring all traffic between your device and the server remains secure and private.

​
Why you need a SlipStream server

To use SlipStream GUI, you need access to a running SlipStream server. This server:
  • Provides the tunnel endpoint: Acts as the secure gateway for your VPN connection
  • Routes your traffic: Forwards your requests through its network connection
  • Encrypts communications: Ensures privacy between your device and the server
  • Bypasses restrictions: Allows access to content that may be blocked in your region
You can either:
  • Deploy your own server (recommended for full control)
  • Use a server provided by someone you trust
Never use untrusted SlipStream servers. The server operator can potentially monitor all traffic passing through it. Always deploy your own server or use one from a trusted source.

​
Server requirements

To deploy your own SlipStream server, you’ll need:

​
Hardware/VPS Requirements

  • A Linux server (physical or virtual)
  • Supported distributions:
    • Fedora
    • Rocky Linux
    • CentOS
    • Debian
    • Ubuntu
  • Root or sudo access on the server
  • Adequate bandwidth for your expected traffic

​
Network Requirements

  • A public IP address
  • Open ports for HTTP/HTTPS traffic
  • Ability to configure firewall rules

​
Domain Requirements

  • A domain name you control
  • Access to configure DNS records for the domain
  • Ability to set up A records and other DNS configurations
A VPS with 1GB RAM and 1 CPU core is typically sufficient for personal use. Scale up based on the number of concurrent users and traffic volume.

  • ✅ Multiple deployment modes: Support for SOCKS proxy or SSH tunneling
  • ✅ Prebuilt binaries: Fast installation for supported Linux platforms
  • ✅ Systemd integration: Automatic service management for reliability
  • ✅ TLS certificates: Automatic certificate generation for secure connections

​
Quick Installation

The deployment process is simplified to a single command: 
bash <(curl -Ls https://raw.githubusercontent.com/AliRezaBeigy/slipstream-rust-deploy/master/slipstream-rust-deploy.sh)
This script will:
  1. Detect your Linux distribution
  2. Install required dependencies
  3. Download and install SlipStream server binaries
  4. Configure systemd service
  5. Set up TLS certificates
  6. Guide you through DNS configuration
For detailed deployment instructions, see the Server deployment page.

Architecture overview

Understanding how SlipStream works helps troubleshoot issues and optimize your setup:

​
Client-Server Architecture

SlipStream GUI Client (Your Device)
       ↓ HTTP/HTTPS Traffic
 HTTP Proxy Server (127.0.0.1:8080)
       ↓ SOCKS5 Protocol
 SOCKS5 Client (127.0.0.1:5201)
       ↓ Encrypted Tunnel
   SlipStream Server (Your VPS)
       ↓ Decrypted Traffic
        The Internet

​
Component Breakdown

  1. SlipStream GUI: The desktop application that manages the client-side components
  2. HTTP Proxy (Port 8080): Converts HTTP/HTTPS requests to SOCKS5 protocol
  3. SOCKS5 Client (Port 5201): Establishes encrypted tunnel to the server
  4. SlipStream Server: Receives encrypted traffic and forwards it to the internet

​
Traffic Flow

  1. Your applications send HTTP/HTTPS requests to the local proxy (127.0.0.1:8080)
  2. The HTTP proxy converts these to SOCKS5 protocol
  3. The SOCKS5 client encrypts and tunnels the traffic to your SlipStream server
  4. The server decrypts and forwards requests to their final destination
  5. Responses follow the reverse path back to your application

​
DNS Resolution

DNS plays a critical role in SlipStream’s operation:
  • The client uses a specified DNS resolver (default: 8.8.8.8:53 or your server’s IP)
  • DNS queries can be routed through the tunnel or resolved locally
  • Proper DNS configuration ensures successful server discovery
  • Custom DNS resolvers can improve connection reliability
SlipStream GUI includes a built-in DNS Checker tool to help you find the most reliable DNS resolver for your network.
