查看“IP Linux command line”的源代码

本文提供了开始使用Linux内核工具ip <ref>https://linux.die.net/man/8/ip</ref>所需的基本信息。

=简介=
:ip命令用来 <ref>https://linux.die.net/man/8/ip</ref>显示/操纵网络接口的路由，设备，策略路由和隧道。 

=开始使用=

*检查网络接口

<syntaxhighlight lang="bash">
Board $> ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: can0: <NOARP,ECHO> mtu 16 qdisc noop state DOWN group default qlen 10
    link/can 
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:80:e1:42:43:65 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.237/22 brd 192.168.3.255 scope global dynamic eth0
       valid_lft 172057sec preferred_lft 172057sec
    inet 192.168.0.4/32 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::280:e1ff:fe42:4365/64 scope link 
       valid_lft forever preferred_lft forever
4: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN group default qlen 1000
    link/sit 0.0.0.0 brd 0.0.0.0
</syntaxhighlight>

*为指定网络接口分配IP地址
 Board $> ip addr add 192.168.1.53 dev eth0

*删除IP地址
 Board $> ip addr del 192.168.1.53 dev eth0
*禁用接口
 Board $> ip link set eth0 down
*启用接口
 Board $> ip link set eth0 up

*检查路由表
 Board $> ip route show
 default via 192.168.3.254 dev eth0 proto dhcp src 192.168.1.237 metric 1024 
 192.168.0.0/22 dev eth0 proto kernel scope link src 192.168.1.237 
 192.168.3.254 dev eth0 proto dhcp scope link src 192.168.1.237 metric 1024 
*增加静态路由
 Board $> ip route add 192.168.2.0/16 via 192.168.1.1 dev eth0

*移除静态路由
 Board $> ip route del 192.168.2.0/16
*设置默认网关
 Board $> ip route add default via 192.168.1.1
