O projeto Headscale desenvolve uma implementa\u00e7\u00e3o aberta do componente de servidor da rede VPN Tailscale, permitindo criar redes VPN semelhantes \u00e0s da Tailscale em suas pr\u00f3prias infraestruturas, sem depender de servi\u00e7os de terceiros. O c\u00f3digo do Headscale \u00e9 escrito na linguagem Go e distribu\u00eddo sob a licen\u00e7a BSD. O projeto \u00e9 liderado por Juan Font Alonso, da Ag\u00eancia Espacial Europeia. <\/p>\n

A Tailscale permite conectar um n\u00famero arbitr\u00e1rio de hosts espacialmente dispersos em uma \u00fanica rede, constru\u00edda de maneira semelhante a uma rede mesh, onde cada n\u00f3 interage diretamente com outros n\u00f3s (P2P) ou atrav\u00e9s de n\u00f3s vizinhos, sem transmitir tr\u00e1fego por servidores externos centralizados. VPN<\/a>-provedor. O gerenciamento de acesso e rotas baseado em ACL \u00e9 suportado. Para estabelecer canais de comunica\u00e7\u00e3o em condi\u00e7\u00f5es de uso de tradutores de endere\u00e7os (NAT), s\u00e3o fornecidos suporte para mecanismos STUN, ICE e DERP (semelhante ao TURN, mas baseado em HTTPS). Em caso de bloqueio do canal de comunica\u00e7\u00e3o entre determinados n\u00f3s, a rede pode reestruturar a rotea\u00e7\u00e3o para direcionar o tr\u00e1fego atrav\u00e9s de outros n\u00f3s.

\"O<\/center> <\/p>\n

O Tailscale se diferencia do projeto Nebula, tamb\u00e9m destinado \u00e0 cria\u00e7\u00e3o de redes VPN distribu\u00eddas com rotea\u00e7\u00e3o mesh, pelo uso do protocolo Wireguard para a transmiss\u00e3o de dados entre n\u00f3s, enquanto no Nebula s\u00e3o utilizadas as contribui\u00e7\u00f5es do projeto Tinc, que utiliza o algoritmo AES-256-GSM para criptografar pacotes (o Wireguard utiliza o cript\u00f3grafo ChaCha20, que em testes demonstra uma capacidade e responsividade superiores). <\/p>\n

Um projeto semelhante chamado Innernet tamb\u00e9m est\u00e1 em desenvolvimento, onde o protocolo Wireguard \u00e9 utilizado para a troca de dados entre os n\u00f3s. Ao contr\u00e1rio do Tailscale e do Nebula, o Innernet utiliza um sistema diferente de controle de acesso, que n\u00e3o se baseia em ACL com anexa\u00e7\u00e3o de tags a n\u00f3s individuais, mas sim na divis\u00e3o de sub-redes e na aloca\u00e7\u00e3o de diferentes intervalos. endere\u00e7os IP<\/a>, como em redes de internet convencionais. Al\u00e9m disso, em vez da linguagem Go, o Innernet utiliza a linguagem Rust. H\u00e1 tr\u00eas dias foi publicada a atualiza\u00e7\u00e3o do Innernet 1.5 com melhorias no suporte \u00e0 supera\u00e7\u00e3o de NAT. H\u00e1 tamb\u00e9m o projeto Netmaker, que permite unir redes com topologias diferentes usando o Wireguard, mas seu c\u00f3digo \u00e9 fornecido sob a licen\u00e7a SSPL (Server Side Public License), que n\u00e3o \u00e9 aberta devido a exig\u00eancias discriminat\u00f3rias. <\/p>\n

O Tailscale \u00e9 distribu\u00eddo sob um modelo Freemium, permitindo o uso gratuito para indiv\u00edduos e acesso pago para empresas e equipes. Os componentes cliente do Tailscale, com exce\u00e7\u00e3o dos aplicativos gr\u00e1ficos para Windows e macOS, s\u00e3o desenvolvidos como projetos abertos sob a licen\u00e7a BSD. O software servidor, operado pela empresa Tailscale, que fornece autentica\u00e7\u00e3o ao conectar novos clientes, coordena o gerenciamento de chaves e organiza a intera\u00e7\u00e3o entre os n\u00f3s, \u00e9 propriet\u00e1rio. O projeto Headscale elimina essa limita\u00e7\u00e3o e oferece uma implementa\u00e7\u00e3o aberta independente dos componentes servidor do Tailscale.

\"O<\/center> <\/p>\n

O Headscale assume as fun\u00e7\u00f5es de troca de chaves p\u00fablicas entre os n\u00f3s, al\u00e9m de realizar opera\u00e7\u00f5es de atribui\u00e7\u00e3o de endere\u00e7os IP e dissemina\u00e7\u00e3o de tabelas de roteamento entre os n\u00f3s. Na sua forma atual, o Headscale implementa todas as principais funcionalidades do servidor de controle, exceto o suporte a MagicDNS e Smart DNS. Em particular, s\u00e3o suportadas fun\u00e7\u00f5es de registro de n\u00f3s (incluindo via web), adapta\u00e7\u00e3o da rede \u00e0 adi\u00e7\u00e3o ou remo\u00e7\u00e3o de n\u00f3s, particionamento de subredes por meio de namespaces (uma rede VPN pode ser criada para v\u00e1rios usu\u00e1rios), organiza\u00e7\u00e3o do acesso dos n\u00f3s a subredes em diferentes namespaces, gerenciamento de roteamento (incluindo a atribui\u00e7\u00e3o de n\u00f3s de sa\u00edda para acesso ao mundo externo), segrega\u00e7\u00e3o de acesso atrav\u00e9s de ACL e funcionamento do servi\u00e7o DNS.
