本文介绍了用于激活和关闭网络接口的控制脚本及其功能。这些脚本位于/etc/sysconfig/network-scripts/目录下，支持IPv4和IPv6的配置与管理，包括IP别名、PPP、USB接口及无线网络等的启动与关闭。

接口控制脚本

这两个脚本在网络接口打开的时间执行初始化操作

/etc/sysconfig/network-scripts/中所有被引用的控制脚本

ifup-aliases — Configures IP aliases from interface configuration files when more than one IP address is associated with an interface.
ifup-ippp and ifdown-ippp — Brings ISDN interfaces up and down.
ifup-ipsec and ifdown-ipsec — Brings IPsec interfaces up and down.
ifup-ipv6 and ifdown-ipv6 — Brings IPv6 interfaces up and down.
ifup-ipx — Brings up an IPX interface.
ifup-plip — Brings up a PLIP interface.
ifup-plusb — Brings up a USB interface for network connections.
ifup-post and ifdown-post — Contains commands to be executed after an interface is brought up or down.
ifup-ppp and ifdown-ppp — Brings a PPP interface up or down.
ifup-routes — Adds static routes for a device as its interface is brought up.
ifdown-sit and ifup-sit — Contains function calls related to bringing up and down an IPv6 tunnel within an IPv4 connection.
ifup-sl and ifdown-sl — Brings a SLIP interface up or down.
ifup-wireless — Brings up a wireless interface.

在所有接口上执行这两个操作相当于执行 /etc/init.d/network start 或stop

网络功能文件

RHEL/Fedora包含几个重要的打开,关闭网络接口的通用功能文件,它们包含每个接口控制脚本需要调用的功能.

/etc/sysconfig/network-scripts/network-functions中的文件负责IPV4网络的通用功能,所完成的功能包含通知应用程序接口状态改变,设置主机名,寻找网关,添加默认路由,或者其它的功能

/etc/sysconfig/network-scripts/network-functions-ipv6中的文件负责IPV6方面的功能,包括配置和删除静态IPV6路由,创建和删除通道,添加和移除接口的IPV6地址
