root@netmonster# ip addr help
Usage: ip addr {add|del} IFADDR dev STRING
ip addr {show|flush} [ dev STRING ] [ scope SCOPE-ID ]
[ to PREFIX ] [ FLAG-LIST ] [ label PATTERN ]
IFADDR := PREFIX | ADDR peer PREFIX
[ broadcast ADDR ] [ anycast ADDR ]
[ label STRING ] [ scope SCOPE-ID ]
SCOPE-ID := [ host | link | global | NUMBER ]
FLAG-LIST := [ FLAG-LIST ] FLAG
FLAG := [ permanent | dynamic | secondary | primary |
tentative | deprecated ]
Example - ip addr add 192.168.1.1/24 dev eth0
该命令将添加IP地址192.168.2.2/24到eth0网卡上.
下面看看ip route命令：
root@netmonster# ip route help
Usage: ip route { list | flush } SELECTOR
ip route get ADDRESS [ from ADDRESS iif STRING ]
[ oif STRING ] [ tos TOS ]
ip route { add | del | replace | change | append | replace |
monitor} ROUTE
SELECTOR := [ root PREFIX ] [ match PREFIX ] [ exact PREFIX ]
[ table TABLE_ID ] [ proto RTPROTO ]
[ type TYPE ] [ scope SCOPE ]
ROUTE := NODE_SPEC [ INFO_SPEC ]
NODE_SPEC := [ TYPE ] PREFIX [ tos TOS ]
[ table TABLE_ID ] [ proto RTPROTO ]
[ scope SCOPE ] [ metric METRIC ]
INFO_SPEC := NH OPTIONS FLAGS [ nexthop NH ]...
NH := [ via ADDRESS ] [ dev STRING ] [ weight NUMBER ] NHFLAGS
OPTIONS := FLAGS [ mtu NUMBER ] [ advmss NUMBER ]
[ rtt NUMBER ] [ rttvar NUMBER ]
[ window NUMBER] [ cwnd NUMBER ] [ ssthresh REALM ]
[ realms REALM ]
TYPE := [ unicast | local | broadcast | multicast | throw |
unreachable | prohibit | blackhole | nat ]
TABLE_ID := [ local | main | default | all | NUMBER ]
SCOPE := [ host | link | global | NUMBER ]
FLAGS := [ equalize ]
NHFLAGS := [ onlink | pervasive ]
RTPROTO := [ kernel | boot | static | NUMBER ]
Example - ip route add 192.168.2.0/24 via 192.168.1.254
该示例将添加一条通过192.168.1.254到网络192.168.2.0/24的路由。
最后，看看ip rule命令：
root@netmonster# ip rule help
Usage: ip rule [ list | add | del ] SELECTOR ACTION
SELECTOR := [ from PREFIX ] [ to PREFIX ] [ tos TOS ] [ fwmark FWMARK ]
[ dev STRING ] [ pref NUMBER ]
ACTION := [ table TABLE_ID ] [ nat ADDRESS ]
[ prohibit | reject | unreachable ]
[ realms [SRCREALM/]DSTREALM ]
TABLE_ID := [ local | main | default | NUMBER ]
Example - ip rule add from 192.168.2.0/24 prio 32777 reject
