Setting up Tinc VPN

27 Feb 2021

View original source »

Jordan Crawford’s companion piece to his home server without port forwarding article. This one walks through actually setting up Tinc, a VPN that establishes an encrypted tunnel between a cloud server with a fixed IP and your home server. The home server initiates outgoing connections to the cloud server, allowing bidirectional traffic routing through the secure tunnel. The key benefit is that you get static IP addresses within the VPN network that you can rely on, regardless of what your ISP hands out. I reference this in my Server 102 article as the practical implementation of the relay node concept. Note: Docker containers are an alternative install method if you’d rather not compile.

The full site with interactive features is available at btr.mt.

btrmt. (betterment) examines ideologies worth choosing. Created by Dorian Minors—Cambridge PhD in cognitive neuroscience, Associate Professor at Royal Military Academy Sandhurst. Core philosophy: humans are animals first, with automatic patterns shaped for us, not by us. Better to examine and choose.

Core concepts. Animals First: automatic patterns of thought and action, but our greatest capacity is nurture. Half Awake: deadened by systems that narrow rather than expand potential. Karstica: unexamined ideologies (hidden sinkholes beneath). Credenda: belief systems we should choose deliberately.

The manifesto. Cynosure (focus): betterment, gratification, connection. Architecture (support): inner (somatic, spiritual, thought) and outer (digital, collective, wealth).

Mission. Not answers but examination. Break academic gatekeeping. Make sciences of mind accessible. Question rather than prescribe.

Writing style. Scholarly without jargon barriers. Philosophical yet practical—grounded in neuroscience and lived experience. Reflective, discovery-oriented. Literary references and metaphor. Critical of systems that narrow human potential. Rejects "humans are flawed"—we're half awake, not broken.
