How to add IP under CentOS First, add a single IP method: # cd/etc/sysconfig/network-scripts # CP Ifcfg-eth0 ifcfg-eth0:0 # Nano ifcfg-eth0:0 Copy Code Copy a eth0 file with the CP command, the new file name is eth0:0, and then edit the file with the nano. Not used to using the Nano can be used with the VI command. Edit after opening file: device=eth0:0 #此处添加: 0, keeping the same file name, adding multiple IP increments sequentially Onboot=yes #是否开机激活 Bootproto=static #静态IP, please enter DHCP

network port in ifconfig: The ifconfig tool configures network interfaces through command parameters. We only need to specify the most common parameters; Ifconfig network port IP address HW * Instance 1:For example, we use ifconfig to debug the address of the eth0 Nic. [root@localhost ~]# ifconfig eth0 down [root@localhost ~]# ifconfig eth0 192.168.1.99 broadcast 192.168.1.255 netmask 255.255.255.0[root@localhost ~]# ifconfig eth0 up [root@localhost

). All packets using this route will Be gatewayed through "mango-GW". The device which will be actually be used for that route depends on how we Can reach "mango-GW"-the static route to "mango-GW" will have to be set up before. Format: Route add-net {network-address} netmask {netmask} Dev {interface-name} The routing rules added to the specified network. Parameter {network-address}: used to specify

change the system's configuration file about the NIC. If you want to fix the IP address of the network interface, there are currently three methods: one is to modify the IP address through the various distribution and version-specific tools; the other is to modify the network interface configuration file directly; The third is to modify specific files, add ifconfig instructions to specify the IP address of the network card, For example, in Redhat or Fedora, the Ifconfig's name is written into/e

In Linux, how do I set IP addresses? We can use commands to set the IP address, but the prerequisite for this method is that the user needs the root permission. The nic ip Address Configuration information is stored in the/etc/sysconfig/network-script/ifcfg-eth0 file of the Linux system. The specific format is:# Cat ifcfg-eth0 [root @ localhost network-Scripts] # Device = eth0 Bootproto = none Onboot = Yes Type = Ethernet Netmask = 255.255.2

In order for the device to access another subnet, you need to increase the routing to the sub-network in the device, here are some information. The basic operations are as follows:In general, to be able to access other subnets to set up the route, for example, your host is in 192.168.10.0/24, and you want to access the 192.168.20.0/24 network host, of course, you know a gateway IP, For example 192.168.10.1 (must be on the same subnet as your host), you can configure the route as such.Add routeRo

route command are as follows:Destination targetThe destination network or destination host. Target network or target host. GatewayThe gateway address or '*' If none set. gateway address, if not, an asterisk is displayed. genmask network mask The netmask for the destination net; '255. 255.255 'For A host destination and '0. 0.0.0 'for the default route. flags possible flags include flag, commonly used U and G. U (route is up) routing enabled

modify the specific file and add the ifconfig instruction to specify the IP address of the NIC. For example, in Redhat or Fedora, the name of the Ifconfig is written into the/etc/rc.d/rc.local file;Ifconfig How to configure network ports:Ifconfig tools to configure the network interface method is through the parameters of the directive to achieve the purpose, we only say the most commonly used parameters;Ifconfig Network port IP address HW MAC address netma
