如标题所示，有没有一种方法可以使用 inotify/inotify-tools 通知最近打开的套接字？据我所知，inotify 仅适用于 inode，并且专门测试这些 inode 是否是套接字并不是 inotify 实际上能够做到的。除此之外，我似乎无法找到套接字 FD 的存储位置。我只能看到它们的文件描述符，它们是符号链接：

# ls -l /proc/29711/fd/10 
lrwx------ 1 root root 64 Mar  6 17:04 /proc/29711/fd/10 -> socket:[750728]

# stat /proc/29711/fd/10
  File: `/proc/29711/fd/10' -> `socket:[750728]'

我在服务器上安装了有效证书，并且在将 -CApath 选项与 OpenSSL 一起使用时，证书链有效。但是，如果我不提供 -CApath 选项，我会收到：

19:self signed certificate in certificate chain

当我在没有 -CApath 的情况下尝试使用 Google 的 HTTPS 端口时，OpenSSL 返回：

20:unable to get local issuer certificate

两者有什么区别？

标题说明了一切。这是在 Xen 管理程序上运行的全新 Fedora 17 系统。不知道为什么它不会启动
