查找 VPN 客户端的本地 IP

查找 VPN 客户端的本地 IP

我有两台服务器服务器A和服务器B。服务器B是服务器A的VPN。当服务器A位于服务器B的VPN后面时,如何在服务器B上找到服务器A的本地IP?我认为当我发出命令“ifconfig”时应该列出它,但我不太确定当时我正在寻找哪个IP。

ifconfig -a 的输出

答案1

从标签来看,我猜您正在运行 OpenVPN。 OpenVPN 使用 tun 或 tap 隧道,因此tun0.那么你的本地 IP(在 VPN 上)是 10.8.0.1,这很奇怪(因为它让我觉得是一个配置错误)也是对等 IP。

BTW:在 Linux 上,ifconfig(朋友)基本上已经过时并被ip命令取代。ip addr ls会给你所有的地址。
