Yggdrasil my computers


Yggdrasil is a thing of beauty. A smart and easy-to-use implementation of an overlay network.
I’ve equipped most of my servers, my PCs and my phone with this daemon, building a mesh network over all my beloved computers.

I’ll keep updated this list of my nice use cases.

Workaround the lack of IPv6

I don’t have IPv6 connectivity at home. Accessing my IPv6-only VPS would not be immediate. But with yggdrasil I just need to have a route to it, via another IPv4 VPS I can peer to.
Now I can psql into my backend (which doesn’t need IPv4 at all) across a securely encrypted tunnel, provided the middle peer stays up.
It also saves me the money needed to reserve a precious IPv4 address. \o/
