Dynamic Host Configuration Protocol Client Daemon (net-misc/dhcpcd)是一个能够处理 IPv4 和 IPv6 配置的流行 DHCP 客户端。

安装

USE 标记

USE flags for net-misc/dhcpcd A fully featured, yet light weight RFC2131 compliant DHCP client

debug Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
embedded Embed the definitions of dhcp options in the dhcpcd executable
ipv6 Add support for IP version 6
privsep Enable support for privilege separation
udev Enable virtual/udev integration (device discovery, power and storage device support, etc)

Emerge

使用以下命令安装dhcpcd:

root #emerge --ask net-misc/dhcpcd

配置

文件

所有 dhcpcd 配置都可以在 /etc/dhcpcd.conf 文件中设置,但如今大多数计算机都通过路由或运行 DHCP 服务的接入点连接网络,因此 dhcpcd 在大多数安装中可以开箱即用。如果需要高级配置,man 5 dhcpcd.conf[1] 将会有所帮助。

静态IP地址

如果网络适配器需要配置静态IP地址,需要将相应数据添加到 /etc/dhcpcd.conf[1] 以下是编辑 DHCPCD 配置文件来手动添加静态地址、路由和 DNS 的示例:

FILE /etc/dhcpcd.conf
static ip_address=192.168.0.10/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1

一次性 DHCP

要为网络接口配置一次性 DHCP,使用以下命令:

root #dhcpcd eth0

确保将上述命令中的 eth0 替换为适当的网络接口名称。
