Traceroute 用于检查我的笔记本电脑和 google.com 之间的跳数

我是 Linux 新手，正在尝试在 ubuntu 终端中学习 traceroute 命令。我在终端中输入 ping 命令到 google.com，结果是：

vscoder@vscoder-VirtualBox:~$ ping google.com

vscoder@vscoder-VirtualBox:~$

但是当我跟踪路由到 google.com 时，它显示以下输出：

vscoder@vscoder-VirtualBox:~$ traceroute google.com

 11   *  *  *

 13   *  * ^C
vscoder@vscoder-VirtualBox:~$

我不知道为什么它没有向我显示跃点的 IP 地址。请在这里帮助我。

我尝试了“traceroute -I google.com”并且它有效。

vscoder@vscoder-VirtualBox:~$ traceroute -I google.com
traceroute to google.com (142.250.193.206), 64 hops max

vscoder@vscoder-VirtualBox:~$

traceroute -I, --icmp：指定使用ICMP ECHO作为探针。

尝试lft（“第四层跟踪路由，执行 TCP 跟踪路由，如traceroute -T”）

例子：-

sudo lft google.com  
Tracing .........**T
TTL LFT trace to lhr25s26-in-f14.1e100.net (172.217.169.14):80/tcp
