试试Linux下的ip命令ifconfig已经过时了
================================================================================
linux的**ip**命令和**ifconfig**类似但前者功能更强大并旨在取代后者。使用ip命令只需一个命令你就能很轻松地执行一些网络管理任务。ifconfig是net-tools中已被废弃使用的一个命令许多年前就已经没有维护了。iproute2套件里提供了许多增强功能的命令ip命令即是其中之一。
![Net tools vs Iproute2](http://linoxide.com/wp-content/uploads/2014/05/Linux-Nettools-vs-Iproute2.png)
要安装ip请[点击这里][1]下载**iproute2套装工具** 。不过大多数Linux发行版已经预装了iproute2工具。
你也可以使用git命令来下载最新源代码来编译
$ git clone https://kernel.googlesource.com/pub/scm/linux/kernel/git/shemminger/iproute2.git
![iproute2 git clone](http://linoxide.com/wp-content/uploads/2014/04/iproute2-git-clone.png)
### 设置和删除Ip地址 ###
要给你的机器设置一个IP地址可以使用下列ip命令
$ sudo ip addr add 192.168.0.193/24 dev wlan0
请注意IP地址要有一个后缀比如/24。这种用法用于在无类域内路由选择CIDR中来显示所用的子网掩码。在这个例子中子网掩码是255.255.255.0。
在你按照上述方式设置好IP地址后需要查看是否已经生效。
$ ip addr show wlan0
![set ip address](http://linoxide.com/wp-content/uploads/2014/04/set-ip-address.png)
你也可以使用相同的方式来删除IP地址只需用del代替add。
$ sudo ip addr del 192.168.0.193/24 dev wlan0
![delete ip address](http://linoxide.com/wp-content/uploads/2014/04/delete-ip-address.png)
### 列出路由表条目 ###
ip命令的路由对象的参数还可以帮助你查看网络中的路由数据并设置你的路由表。第一个条目是默认的路由条目你可以随意改动它。
在这个例子中有几个路由条目。这个结果显示有几个设备通过不同的网络接口连接起来。它们包括WIFI、以太网和一个点对点连接。
$ ip route show
![ip route show](http://linoxide.com/wp-content/uploads/2014/04/ip-route-show.png)
假设现在你有一个IP地址你需要知道路由包从哪里来。可以使用下面的路由选项译注列出了路由所使用的接口等
$ ip route get 10.42.0.47
![ip route get](http://linoxide.com/wp-content/uploads/2014/04/ip-route-get.png)
### 更改默认路由 ###
要更改默认路由使用下面ip命令
$ sudo ip route add default via 192.168.0.196
![default route](http://linoxide.com/wp-content/uploads/2014/04/default-route.png)
### 显示网络统计数据 ###
使用ip命令还可以显示不同网络接口的统计数据。
![ip statistics all interfaces](http://linoxide.com/wp-content/uploads/2014/04/ip-statistics-all-interfaces.png)
当你需要获取一个特定网络接口的信息时,在网络接口名字后面添加选项**ls**即可。使用多个选项**-s**会给你这个特定接口更详细的信息。特别是在排除网络连接故障时,这会非常有用。
$ ip -s -s link ls p2p1
![ip link statistics](http://linoxide.com/wp-content/uploads/2014/04/ip-link-statistics-.png)
### ARP条目 ###
地址解析协议ARP用于将一个IP地址转换成它对应的物理地址也就是通常所说的MAC地址。使用ip命令的neigh或者neighbour选项你可以查看接入你所在的局域网的设备的MAC地址。
$ ip neighbour
![ip neighbour](http://linoxide.com/wp-content/uploads/2014/04/ip-neighbour.png)
### 监控netlink消息 ###
也可以使用ip命令查看netlink消息。monitor选项允许你查看网络设备的状态。比如所在局域网的一台电脑根据它的状态可以被分类成REACHABLE或者STALE。使用下面的命令
$ ip monitor all
![ip monitor all](http://linoxide.com/wp-content/uploads/2014/04/ip-monitor-all.png)
### 激活和停止网络接口 ###
你可以使用ip命令的up和down选项来激某个特定的接口就像ifconfig的用法一样。
在这个例子中当ppp0接口被激活和在它被停止和再次激活之后你可以看到相应的路由表条目。这个接口可能是wlan0或者eth0。将ppp0更改为你可用的任意接口即可。
$ sudo ip link set ppp0 down
$ sudo ip link set ppp0 up
![ip link set up and down](http://linoxide.com/wp-content/uploads/2014/04/ip-link-set-up-and-down.png)
### 获取帮助 ###
当你陷入困境不知道某一个特定的选项怎么用的时候你可以使用help选项。man页面并不会提供许多关于如何使用ip选项的信息因此这里就是获取帮助的地方。
比如想知道关于route选项更多的信息
$ ip route help
![ip route help](http://linoxide.com/wp-content/uploads/2014/04/ip-route-help.png)
### 小结 ###
对于网络管理员们和所有的Linux使用者们ip命令是必备工具。是时候抛弃ifconfig命令了特别是当你写脚本时。
