谁监听端口

谁监听端口

我的邮件服务器和另一个服务之间存在冲突。

netstat -ltnp | grep -w ': 25'

结论：

(Not all processes could be identified, non-owned process info
  will not be shown, you would have to be root to see it all.)
tcp6 0 0 ::: 25 ::: * LISTEN -
The problem is that I do not know who is listening on port 25. How can this be determined?

我修好了它：

sudo netstat -tulpn | grep LISTEN

如果您不是 root 并且不是进程所有者，那么您无法在 deprecated netstat（或 current ）输出中看到进程。ss

要查看所有进程的进程信息，你需要以 root 身份运行它，例如使用sudo。例如：

sudo netstat -ltnp | grep -w ': 25'
