DOTYCAT TUNNEL - Auto Script for VPN Services

DOTYCAT TUNNEL is an automation script designed to simplify the process of deploying and managing VPN services on Linux servers. With this tool, users can quickly set up advanced VPN protocols such as VLESS, VMESS, TROJAN, and SOCKS, all with full support for WebSocket TLS, Non-TLS, and gRPC. Additionally, DOTYCAT TUNNEL extends its functionality to SSH-based services like Stunnel, Dropbear, BadVPN, and WebSocket with TLS and Non-TLS, making it a powerful all-in-one solution for private tunneling and secure internet connections.

Supported Protocols

DOTYCAT TUNNEL integrates multiple tunneling protocols to meet various needs:

• VLESS - Lightweight and efficient protocol for Xray core.
• VMESS - Reliable protocol designed for secure tunneling.
• TROJAN - TLS-based protocol that mimics HTTPS traffic.
• SOCKS - Flexible proxy for general usage.
• SSH (Stunnel, Dropbear, WebSocket) - Classic and stable secure shell access.
• BadVPN - Provides UDP tunneling for gaming and real-time applications.

Connection Modes

This script allows different connection modes to ensure compatibility with ISPs and network conditions:

• WebSocket TLS on port 443
• WebSocket Non-TLS on port 80
• gRPC running on port 443
• Direct SSH and Stunnel on port 443
• Dropbear and Non-TLS WebSocket on port 80

Key Features

DOTYCAT TUNNEL includes essential functions for server and domain management:

• Check Server Status - Monitor uptime and resource usage easily.
• Change Domain - Replace or update the server domain name.
• Renew SSL - Automatically renew SSL certificates for secure connections.
• Custom DNS - Configure or switch to preferred DNS resolvers.
• Multi-protocol Management - Install, remove, and manage VPN accounts.

Ports and Security

All TLS-based connections are configured to use port 443, ensuring compatibility with HTTPS traffic and bypassing many ISP restrictions. Non-TLS connections are set to port 80, allowing easy access in environments where TLS traffic might be restricted. gRPC connections also run on port 443, making them secure and stable for modern tunneling.

Advantages of Using DOTYCAT TUNNEL

With its comprehensive protocol support, DOTYCAT TUNNEL is highly suitable for users who want flexible and secure connections. It is especially beneficial for:

• Bypassing internet restrictions and censorship.
• Enhancing security with SSL/TLS encryption.
• Supporting multiple tunneling methods in one script.
• Easy management of domains, SSL, and DNS settings.
• Providing stable and optimized performance for browsing, streaming, and gaming.
