NIC configuration for Linux

Linux network card can be a life temporarily modified, or can be a GUI modification, but our most commonly used is to edit the configuration file to make it permanent, so that we do not need to be like a temporary modification of every boot to reset so much trouble, then let's look at this not troublesome network adapter configuration method It!

2. First we enter the configuration file for the NIC:

   
   [[Email protected]~]# vi/etc/sysconfig/network-scripts/ifcfg-eth0//Enter edit

   
   

   Device=eth0

   hwaddr=00:0c:29:d0:00:08

   Type=ethernet

   uuid=3849f187-d7be-4641-9321-11786a83277e

   Onboot=yes//self-booting, here means allow

   Nm_controlled=yes

   Bootproto=static//Here is the protocol, we set to static, the default is DHCP (dynamic)

   ipaddr=192.168.12.12//Here is your IP

   NETMASK =255.255.255.0//Here is the mask

4. Press ESC, and then press and hold shift+: Enter to save the

   : Wq

6. Enter service network restart restart NIC

   [Email protected] Desktop]# service network restart

   Shutting down interface eth0: [OK]

   Close Loopback interface: [OK]

   Eject loopback interface: [OK]

   Popup interface eth0: Active connection Status: activated

   Active connection path:/ORG/FREEDESKTOP/NETWORKMANAGER/ACTIVECONNECTION/1

   Determine

7. Input ifconfig view network card parameters

   
   

   [[Email protected] Desktop]# ifconfig

   Eth0 Link encap:ethernet HWaddr 00:0c:29:d0:00:08

   inet addr:192.168.136.130 bcast:192.168.136.255 mask:255.255.255.0

   Lo Link encap:local Loopback

   inet addr:127.0.0.1 mask:255.0.0.0

   Inet6 addr::: 1/128 scope:host
