FAQ

[Arceliar]

I think we should work on improving the FAQ page. We tend to repeat ourselves a lot when answering people's questions, and it would be good if we had that in shape where we could point people to it first.

Maybe we can collect questions (and start working on answers) as comments to this issue.

[Mikaela]

What is the root node, isn't that centralisation?

How does my traffic move on the map? Why do I only have one link while I have more peers?

[Mikaela]

Why are there so many public/private keys in yggdrasil.conf? What do they do / How do they differ?

[Mikaela]

Do I need a firewall with Yggdrasil?

What is peering? How do I get puurs? How should I pick them, where should they be located? How many do I need?

How does autopeering work?

[Mikaela]

Optimal node amount and peering policy was discussed again and I found these links, but they should be in FAQ

I hope I got to at least to the correct direction 😁

---

What is the root node, isn't that centralisation?

The root node is the node with the strongest key and the network is arranged around it. If it changes, there will be a moment while the network readjusts.

How does my traffic move on the map? Why do I only have one link while I have more peers?

The map only shows the tree which is the worst case scenario. Generally the traffic jumps to the closest peer to the destination taking shortcuts across the tree.

Do I need a firewall with Yggdrasil?

Yggdrasil includes a session firewall that is disabled by default, but running an IPv6 firewall is generally recommended or all ports on your system may be open to the network.

What is peering? How do I get puurs? How should I pick them, where should they be located? How many do I need?

Peers are connections between nodes in the network. You can find public peers on https://github.com/yggdrasil-network/public-peers, three to four would be a good amount and they should be located as close as possible. It's recommended that public peers peer with each other.

[Mikaela]

Duplicated/Anycast nodes cannot share any common peer?

They can as long as the signing keys are different
The best way to guarantee that is just to remove the SigningPrivateKey and SigningPublicKey options from the config file altogether, as Yggdrasil will fill them in with random sane defaults each time it starts

(This is an untested configuration.)
