LINUX Nic handwritten configuration file

LINUX Nic handwritten configuration file-Linux Enterprise Application-Linux server application information. The following is a detailed description. /Etc/sysconfig/network-scripts/ifcfg-interface-name

The configuration file ifcfg-interface-name contains most of the details required for the initialization interface. The interface-name varies according to the type and order of the network card. Generally, its names are eth0, eth1, and ppp0. eth indicates the Ethernet (eth0) network card, 0 indicates the first Nic, 1 indicates the second Nic, and ppp0 indicates the first point-to-poirt protocol network interface. The items defined in the ifcfg file depend on the interface type.

The following values are more common:

"DEVICE = name, where name is the name of the physical DEVICE.

IPADDR = addr, where addr is an IP address.

NETMASK = mask, where mask is the network mask value.

"NETWORK = addr, where addr is the NETWORK address.

"BROADCAST = addr, where addr is the BROADCAST address.

"GATEWAY = addr, where addr is the GATEWAY address.

ONBOOT = answer, where answer is yes (the device is activated during boot) or no (the device is not activated during boot)

USERCTL = answer, where answer is yes (non-root users can control this device) or no

"BOOTPROTO = proto, where, proto takes one of the following values: none, no protocol used for guidance; static allocation address; bootp, use BOOTP protocol, or dhcp, use DHCP protocol.

(2) According to the meaning of the above parameters, the setting file for the linpcl.lintec.edu.cn machine is as follows:

[Root @ linpcl root] # cat/etc/sysconfig/networking/devices/ifcfg-rth0

DEVICE = eth0

ONBOOT = yes

BOOTPROTO = static

IPADDR = 192.168.0.2

NETMASK = 255.255.255.0

GATEWAY = 192.168.0.1

(3) Save the file after the parameter configuration is complete, and restart the network device using the/etc/init. d/network restart command. The latest value will take effect.

[Root @ linpcl root] #/etc/rc. d/init. d/network restart

Closing interface eth0: [OK]

Disable the loop interface: [OK]

Set network parameters: [OK]

Pop-up loop interface: [OK]

Pop-up page eth0: [OK]

(4) run the ifconfig command to view the network device status.

[Root @ linpcl root] # ifconfig
