我正在尝试在与 WLAN 接入点连接的 Raspberry-Pi B 上设置 FreeRadius-Server。我创建了证书，就像在自述文件中描述的那样。当我尝试在接入点上登录时，我从服务器获得以下调试输出。

我将用户写入用户文件

ExampleUser Cleartext-Password := "PASSWORD"

困扰我的是用户密码和用户名似乎以加密格式发送到服务器，这可能是它不起作用的原因，但我不知道是什么原因造成的。我正在尝试在 Xubuntu 上使用 PEAP V0 MSCHAPv2 通过 WPA/WPA2 Enterprise 登录，这应该可以工作。如果我选择动态 WEP (802.1x)，Radius-Server 甚至不会收到请求（我正在使用 tshark 监控流量）。

用户名不是从服务器以加密格式发送的，用户密码是。FreeRADIUS 无法检查解密是否成功，因此您知道的唯一方法是解密的密码是否与用户密码匹配。

一个很好的提示是，如果密码包含大量不可打印的字符，就像上面的那样，那么很可能是 RADIUS 服务器和 NAS 之间的密码不正确。

如果你解决了这个问题，你应该在调试输出中看到实际的密码，然后你可以让服务器发送一个接受。
