Virtual private services with tsnet

Tailscale offers a versatile virtual private network solution that enables secure connections between devices on a network, referred to as a tailnet, allowing users to access services like NAS, RDP, and SSH from anywhere. The tool extends its functionality through a library called tsnet, which can be embedded in Go programs, enabling the creation of virtual private services that operate within the same system without requiring root permissions or exposing services to the public internet. These services, each with their own IP address and DNS name, benefit from Tailscale's encrypted tunnels and can obtain HTTPS certificates from Let’s Encrypt. This setup allows hosting multiple services with different confidentiality levels on the same machine, simplifying access control and enhancing security. The blog post details the process of setting up a basic "hello" server using tsnet and provides examples of its practical applications, such as supporting team operations and integrating with tools like Grafana or Minecraft, illustrating the flexibility and security of using tsnet in various contexts.
