我试图弄清楚为什么我的英特尔 NUC 上的 CentOS 7 上的 WiFi 继续死机。作为信息，我有 5 个节点的 Hadoop 集群，它们都配置相同（据我所知），但是，WiFi 上的其他机器不会崩溃。我不知道这台机器出了什么问题。

这是来自 的错误/var/log/messages。这是我经常看到的相同消息，因为我已经观察了这个问题好几天了。

我应该从哪里开始尝试调试？我可以编辑带有更新的原始帖子。

以下是一些我认为可能会有所帮助的事情：

我试图让 Kerberos PAM 在 CentOS 7 上的 RStudio 登录后提取票证而不是销毁它。

我的rstudio文件/etc/pam.d/看起来像：

    #%PAM-1.0
    auth    required        pam_krb5.so retain_after_close debug
    session requisite       pam_krb5.so retain_after_close debug
    account required        pam_krb5.so debug

我知道 RStudio 与 PAM 堆栈通信良好，因为如果我删除第一行，RStudio 将无法登录。我还做了其他操作，让我知道两者是同步的。

根据 RStudio 文档，如果我运行以下命令： pamtester --verbose rstudio <user> authenticate setcred open_session

输入我的密码后，会在/tmp调用中创建一张票，krb5cc_(uid)这是我所期望的。setcred我可以通过删除告诉我这是关键组件的标志来使上述 pamtester 行无法拉票。

在 Keberos PAM 文档中查看说，它的执行与命令标志session相同，auth但它使用命令pam_setcred(PAM_ESTABLISH_CRED)标志运行，这正是我想要的。相同的文档说，如果我添加，retain_after_close那么应该保留票。然而，这并没有发生，我什至不确定它是否真的在拉票。

感谢您提供任何帮助，我已经尽可能尝试了 PAM 文件中标志和参数的所有组合，但无济于事。Kerberos 是一场噩梦。LMK 我还有什么可以帮助的。不幸的是，日志文件没有用，因为如果不理解某行，PAM 会“静默失败”，因此它们不会记录错误。
