ss是Socket Statistics的缩写，用来替代旧的netstat工具，功能更强大，执行更快。它用于查看系统的ss="tags" href="/tags/WangLuo.html" title=网络>网络连接情况，包括TCP、UDP等协议的信息。

一. 命令解析：

ss="prism language-bash">ss="token function">sudo ss ss="token parameter variable">-tulwnp

ss (Socket Statistics)：替代 netstat 的工具，用于查看ss="tags" href="/tags/WangLuo.html" title=网络>网络连接、路由表、接口统计等。
-t：显示 TCP 套接字。
-u：显示 UDP 套接字。
-l：仅显示监听（LISTEN）状态的套接字。
-w：显示 RAW 套接字（较少使用）。
-n：禁用域名解析，直接显示 IP 和ss="tags" href="/tags/DuanKou.html" title=端口>端口号。
-p：显示关联的进程信息（需 sudo 权限）。
sudo：提升权限以查看所有进程的ss="tags" href="/tags/WangLuo.html" title=网络>网络信息。

二. 输出结果

总结：

  • 用途：快速定位系统中所有监听ss="tags" href="/tags/DuanKou.html" title=端口>端口的进程，用于排查ss="tags" href="/tags/DuanKou.html" title=端口>端口冲突、识别不明服务或监控ss="tags" href="/tags/WangLuo.html" title=网络>网络活动。
  • 重点关注：
    • 监听在 0.0.0.0（所有接口）或公网 IP 的ss="tags" href="/tags/DuanKou.html" title=端口>端口，可能存在安全风险。
    • 未知进程或非预期ss="tags" href="/tags/DuanKou.html" title=端口>端口，需进一步检查是否为恶意软件。
