SETUP AND CONFIGURATION OF DDOS-PROOF FRP AND CADDY SERVERS WITH REST API INTEGRATION

We are seeking an experienced system administrator to set up and configure a cloud-based Linux server with FRP (Fast Reverse Proxy) and Caddy.
The server must support dynamic configuration of HTTPS subdomains pointing to local web servers running on client machines.
The solution should be designed to scale efficiently, starting with a test for 100 subdomains and the potential to handle or more subdomains in the future.
--- Project Requirements.
1.
Linux Server Setup.
- Recommend and set up the most suitable Linux distribution (e.
., Ubuntu, CentOS).
- Configure the server to securely host both FRP and Caddy.
2.
FRP Configuration.
- Set up the FRP server to accept connections from multiple clients.
- Enable dynamic creation of customer connections via a REST API, ensuring.
- Unique secure tokens for each client.
- Configuration of specific ports for local services (e.
., localhost:) to be exposed through the server.
- Example API call for adding a customer connection.
POST /api/frp Content-Type.
application/json "customer_name".
"customera", "token".
"secure-token", "local_port".
, "remote_port".
- The system must be able to handle 100 customer connections during the initial test and be scalable to support or more connections.
3.
Caddy Server Configuration.
- Install and configure Caddy as a reverse proxy.
- Use Caddy's REST API to dynamically add and manage subdomains with Let's Encrypt certificates for HTTPS.
- Subdomains will automatically point to the corresponding FRP remote ports.
- Example API call for adding a subdomain.
POST /api/caddy Content-Type.
application/json "subdomain".
"[login to view URL]", "proxy_target".
"http://localhost:.
Scalability Requirements.
- The server must support 100 subdomains with individual local web servers during the initial test phase.
- The design should allow easy scaling to or more subdomains without significant performance degradation.
5.
Security Measures.
- Implement robust DDoS protection for the server.
- Harden the Linux server with industry best practices (e.
., firewall rules, secure configurations).
- Secure all REST API endpoints with proper authentication (e.
., API keys or OAuth).
6.
Testing.
- Verify that a local web server running on a client machine (e.
., `localhost.
) can be accessed via a subdomain (e.
., `[login to view URL]`).
- Test the automation of subdomain configuration, certificate issuance, and scalability to handle multiple connections.
--- Deliverables.
- A fully operational cloud-based Linux server configured with.
- FRP server to handle customer connections dynamically via REST API.
- Caddy server to manage HTTPS subdomains dynamically with Let's Encrypt.
- Documentation detailing.
- The setup process.
- REST API usage for FRP and Caddy configurations.
- Security measures implemented for DDoS protection and server hardening.
- Recommendations for scaling beyond subdomains.
--- Qualifications.
- Proven experience in Linux server administration and cloud-based setups.
- Expertise in configuring and managing FRP and Caddy servers.
- Familiarity with REST API configuration and security best practices.
- Experience with DDoS protection and secure server configurations.
- Excellent documentation and communication skills.
--- Additional Information.
- We will provision the Linux cloud server according to your recommendations.
- Subdomain generation is automated externally and not part of this task.
- Please include in your proposal.
- The Linux distribution you recommend and why.
- Your approach to configuring REST APIs for FRP and Caddy.
- Methods to ensure server security, particularly against DDoS attacks.
- How you plan to design the solution to scale efficiently for or more subdomains.
- Examples of similar projects you’ve completed (if available).
We look forward to working with a skilled professional who can deliver a robust, secure, and scalable solution.
