使用DHCPCD网络管理器

本文基于发布在Gentoo论坛的帖子 并解释了如何使用dhcpcd进行完整的网络堆栈管理。

设置

确保 dhcpcd 已经安装。接下来，将它添加到默认运行级别并启动服务：

root #rc-update add dhcpcd default

root #/etc/init.d/dhcpcd start

此设置偏离了Gentoo手册中的默认网络说明。 它具有在有线和无线网络接口之间提供自动切换的优点。

无线

For wireless use wpa_supplicant. Either

• copy the 10-wpa_supplicant hook into the dhcpcd-hooks directory and restart dhcpcd, or
• have wpa_supplicant configured with the CONFIG_MATCH_IFACE option and run it as a service

安装 hook ：

root #cp /usr/share/dhcpcd/hooks/10-wpa_supplicant /lib/dhcpcd/dhcpcd-hooks

root #/etc/init.d/dhcpcd restart

Important
Do not add wpa_supplicant to any runlevel if using the hook.

To use the wpa_supplicant approach, see the wpa_supplicant's Gentoo wiki page.

测试

Stop dhcpcd and wpa_supplicant, then start dhcpcd with debugging enabled and in the foreground to see dhcpcd starting the connection.

root #/etc/init.d/dhcpcd stop

root #killall wpa_supplicant

root #dhcpcd -dB

dhcpcd[23772]: version 6.4.5 starting
dhcpcd[23772]: udev: starting
dhcpcd[23772]: dev: loaded udev
...

静态IP地址

In case the network interface card should be configured with a static IP address, type it into the graphical user interface. Without the graphical user interface, entries can also be manually added to /etc/dhcpcd.conf as described in Dhcpcd#Static_IP_addresses.

从 Gentoo net.* 脚本迁移

When migrating from Gentoo's net.* scripts it is essential to remove the net.* scripts from the runlevels.

user $rc-config list | grep 'wpa_supplicant\|dhcpcd\|net.'

  net.wlp8s0                default
  dhcpcd                    default

Any match starting with net. must not have a runlevel assigned. In the above example, net.wlp8s0 needs to be removed.

root #rc-update del net.wlp8s0

root #/etc/init.d/net.wlp8s0 stop

Once the network setup works well, it is possible to completely remove the old Gentoo net.* scripts. To do so, disable the netifrc useflag, re-emerge OpenRC and finally unmerge net-misc/netifrc:

root #echo 'sys-apps/openrc -netifrc' >> /etc/portage/package.use

root #emerge --ask --newuse --oneshot sys-apps/openrc

root #emerge --ask --depclean net-misc/netifrc

还可以删除旧的配置文件和符号链接：

root #rm /etc/conf.d/net

root #rm /etc/init.d/net.*

网络依赖服务

Manipulating network dependent services by dhcpcd is no longer supported since openrc-0.16.4.

图形用户界面

A dhcpcd graphical user interface is provided by net-misc/dhcpcd-ui.
