【问题描述】:
我想将 RPI (Raspbian Stretch) 的 eth0 设置为 DHCP,我的目标是当我连接任何使用 TCP/IP 协议进行通信的设备时,该设备将收到一个 IP 地址。
我发现许多指南都导致将 eth0 ip 地址设为静态,这不是我的意图。
当前有一个设备通过 eth0 连接,ifconfig 说它有一些 IP 但 ping 设备的主机名没有得到回复。 wlan0 通过 wifi 连接。
这里有一些信息:
pi@raspberrypi:~ $ ifconfig

pi@raspberrypi:~ $ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
任何关于如何实现我的目标的建议都会很高兴收到。
