Lançado o OpenVPN 2.6 beta1 com dezena de correções e melhorias, confira.
OpenVPN 2.6 beta1
O OpenVPN é um software livre e open-source para criar redes privadas virtuais do tipo ponto-a-ponto ou server-to-multiclient através de túneis criptografados entre computadores. Wikipédia
Houve uma série de novos recursos e melhorias:
- Suporte de aceleração do kernel Data Channel Offload (DCO) para Windows, Linux e FreeBSD.
- Suporte OpenSSL 3.
- Manipulação aprimorada de MTU de túnel, incluindo suporte para MTU pushable.
- Handshake TLS retrabalhado, tornando o OpenVPN imune a ataques de esgotamento do estado do pacote de repetição.
- Adicionado o modo --peer-fingerprint para uma configuração e verificação de certificado mais simplista.
- Negociação de protocolo aprimorada, levando a uma configuração de conexão mais rápida.
