Linux Basics-Network settings

Linux files that store network interface information and MAC address correspondence

Redhat 5:/etc/modprobe.conf

Redhat 6:/etc/udev/rules/70-persistent-net.rules

Temporarily Configure IP address information

Ifconfig

Ifconfig EthX Ip/mask [Up|down]

Ifconfig ethx:x Ip/mask [Up|down] Add multiple addresses under the same NIC

The configured address takes effect immediately, but fails when the network or host is restarted

#永久配置IP地址信息

Network configuration file

/etc/sysconfig/network

Network Interface configuration file

/etc/sysconfig/network-scripts/ifconfig-name

Device= "eth0" #设备名称 to match the name of the filename bootproto= "DHCP" #引导协议 {static|none|dhcp|boottp}, static: Static|nonenm_controlled= "Yes "#是否启用netwokmanagerONBOOT =" yes "#开机时是否自动启动TYPE =" Ethernet "#IPADDR =" "#IP地址NETMASK =" "#子网掩码GATEWAY =" "#默认网关HWADDR = "" #MAC地址, Userctl={yes|no} #是否允许普通用户控制此接口PEERDNS ={yes|no} can be omitted #是否在BOOTPROTO为dhcp是接受由dhcp服务器指定的DNS地址

/etc/sysconfig/network-scripts/ifconfig-ethx:x

Permanently add multiple addresses under one NIC

Network Services

redhat:/etc/init.d/network {Start|stop|restart|status}

#临时配置路由信息

Gateway Settings

Route

Add: Adding routes

-host: Adding host routes

-net: Adding network routes

-net 0.0.0.0

Route add-net|-host DEST GW Nexthop

Route add default GW nexthop

Del: Delete route

-host: Removing host routes

-net: Deleting network routes

Route Del-net 10.0.0.0/8

The configured address takes effect immediately, but fails when the network or host is restarted

#永久配置路由信息

/etc/sysconfig/network-scripts/route-ethx

Add format one:

Target network via next hop

Add format two:

address0=

netmask0=

gateway0=

/etc/sysconfig/network

Networking=yes #是否启用网络功能NETWORKING_IPV6 =yes #是否启动ipv6网络功能HOSTNAME =localhsot.localhost #主机名配置GATEWAY = #全局网关地址

IPROUTE2 module: A powerful IP management module

Command: IP

Link: Network Interface properties

Ip-s Link Show: View NIC interface information

IP Link set interface {up|down} enabled | Shutdown interface

Addr: Protocol Address

Route

IP route add to 10.0.0.0/8 Dev eth0 via 172.16.0.1

IP route flush to 10/8 clears the 10.0.0.0/8 route
