NetworkManager 1.4.2 发布，网络管理软件
引用来自“amita”的评论RH系里，这个和network服务到底什么关系？Gnome的network-manager用于在"Linux桌面"上管理网络,提供有可视化操作界面和命令行工具nmcli. 以Ubuntu桌面为例:
dpkg -L network-manager|grep bin
dpkg -L network-manager-gnome|grep bin
nmcli - command‐line tool for controlling NetworkManager
nm-tool - utility to report NetworkManager state and devices
nm-online - ask NetworkManager whether the network is connected
NetworkManager - network management daemon
nm-applet: 系统托盘小程序(systray applet)
nm-connection-editor: network connection editor for NetworkManager
在命令行重启NetworkManager服务:
sudo service network-manager restart
也就是说,Linux桌面上,network-manager接管了网路,不需要用户操作命令配置.
对比:默认无桌面环境的Ubuntu Server重启eth0:
sudo ifdown eth0 && sudo ifup eth0
1.DHCP配置:
/etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
2.DNS相关配置:
/etc/hosts
/etc/resolv.conf
添加DNS:
sudo nano /etc/resolvconf/resolv.conf.d/head
nameserver x.x.x.x
重新生成resolv.conf:
sudo resolvconf -u
查看DNS:
nslookup server
