Yggdrasil Discussion / Re: What is your practical use...
Last post by sdgathman - September 06, 2023, 04:49:48 PMYggdrasil does relay when you have 2 or more peers (otherwise there is no point).
My practical use is an an alternative to Cjdns that uses TCP instead of UDP (which evades different kinds of attempts to block vpns).
What did I use Cjdns for? The e2e encryption and IP authentication provide a simplified alternative to private certificate authority schemes with signed certs used by large corporations. For any service, I just list all the Cjdns/ygg ips authorized to use it. (E.g. using ipset.) An example would be nameservers. Recursive nameservers are hard to make public without getting DoSed.
Obviously, this doesn't scale - those lists of IPs become like /etc/hosts. This is why Big Corps use a private CA. The central authority also obviates the need for lists of ips on each service - the signed certs list what services they are authorized to access.
A key principle to take away is the distinction between authentication (not an imposter) and authorization (are you authorized to use this service).
You could scale the lists of IPs by providing a well known service that returns whether an IP is authorized for a service (or just return a list of authorized services which can be cached).
As for VPN use, yggdrasil fools firewalls that try to block vpns (by blocking UDP traffic), but allow websites (with possible blacklist). On the other hand, Cjdns connects from behind firewalls that block web traffic, but allow UDP sessions on random ports.

Yggdrasil Discussion / Accessing Yggdrasil in a web b...
Last post by wdc - August 04, 2023, 11:56:37 AMWeb browseer 1 is not using any proxy set inside it (is using system main networking, which is Wireguard VPN) -> it can display Yggdrasil site like http://[21a:34aa:c782:3ad2:1bf8:73f8:141:66e8]/
Web browser 2 is using SOCKS5 proxy 127.0.0.1:1080 which is shadowsocks (protocol) running thanks to V2Ray app/service. and on this browser, i can not display Yggdrasil site.
Question is what to do so it loads in Web browser 2 (Firefox-ESR) while keeping its proxy set like it is?
127.0.0.1:1080 links to remote server of mine with old CentOS + iptables.

Last post by wdc - August 04, 2023, 11:26:40 AMHi, I have setup a Yggdrasil on my server and home computer. Now i would like to be more useful part of this network.
I am not willing to host any yggdrasil site because i do not believe in single point of failure hosting (for that reason i am rather using decentralized Zeronet - https://github.com/zeronet-conservancy/#readme ).
Yggdrasil does not either seem to automatically serve as a relay unlike I2P router.

Last post by 4X_Pro - July 24, 2023, 04:14:24 PMМожно ли запустить на одном компьютере несколько экземпляров yggdrasil? Скажем, чтобы было два интерфейса — один был для подключения к публичным узлам, второй — только для связи между своими устройствами? Или будет конфликт из-за того, что используется один и тот же диапазон IPv6?

Last post by 4X_Pro - July 24, 2023, 04:09:24 PMQuote from: Revertron on October 03, 2022, 08:11:24 PMВсе узлы в сети равноправны. И если у каких-то узлов есть два и более соединения, то этот узел может передавать данные между другими узлами.А где-нибудь есть подробное описание того, как устроен алгоритм поиска нужного узла? То есть как один узел находит путь до другого, если прямой связи между ними нет?
Ты подключаешься к любому крайнему пиру, и получаешь доступ ко всей сети.
