wpa_supplicant não conectando, porque SSL3 não é suportado

  • 772

Eu tenho um laptop rodando Debian GNU/Linux Unstable com Network Manager. Desde uma atualização do OpenSSL (1.1.1 eu acho), não consigo me conectar a uma rede Wi-Fi usando WPA2 Enterprise com PEAP (MSCHAPv2). Em /var/log/syslog, ele diz que SSL3 não é suportado:

O downgrade do OpenSSL corrige isso, é claro, mas não posso usar coisas que são compiladas para versões mais recentes do OpenSSL. Existe alguma maneira de se conectar à rede Wi-Fi?

debian openssl

    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=911389 parece ser relevante. Sugere editar as duas últimas linhas no formato /etc/ssl/openssl.conf. Certifique-se de usar o TLSv1.0, que é o que funcionou na minha horrível instalação do MS AD.

    Obviamente, deve-se pedir ao amigável SysAdmin que pare de usar software proprietário, ou pelo menos aceite versões de protocolo mais recentes.

  2. Para estender a resposta para usuários de outras distribuições Linux, o seguinte pode ajudar a resolver este problema no Fedora 33:

    sudo dnf install crypto-policies-scripts
update-crypto-policies --set LEGACY

    O daemon wpa_supplicant precisa ser reiniciado após a alteração:

    systemctl restart wpa_supplicant

    Para restaurar a configuração padrão, use

    update-crypto-policies --set DEFAULT
