wpa_supplicant 未连接，因为不支持 SSL3

我有一台运行带有网络管理器的 Debian GNU/Linux 不稳定的笔记本电脑。自从 OpenSSL 更新（我认为是 1.1.1）以来，我无法使用带有 PEAP (MSCHAPv2) 的 WPA2 Enterprise 连接到 Wi-Fi 网络。在 中/var/log/syslog，它表示不支持 SSL3：

降级 OpenSSL 当然可以解决这个问题，但是我无法使用编译为较新版本的 OpenSSL 的东西。有什么办法可以连接到 Wi-Fi 网络吗？

答案1

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=911389似乎是相关的。它建议编辑 中的最后两行/etc/ssl/openssl.conf。请务必使用 TLSv1.0，这在我糟糕的 MS AD 安装中起作用。

显然，人们应该要求友好的系统管理员停止使用专有软件，或者至少接受更新的协议版本。

答案2

为了向其他 Linux 发行版的用户扩展答案，以下内容可以帮助解决 Fedora 33 中的此问题：

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

更改后需要重新启动 wpa_supplicant 守护进程：

systemctl restart wpa_supplicant

要恢复默认配置，请使用

update-crypto-policies --set DEFAULT

答案3

在我的 ubuntu 22.04 上
