First of all, my experience, I think Ubuntu Desktop version of the best way to configure the network is to use the Network-manager interface software, because the desktop version of the software is automatically launched. The reasons are as follows:

1. If you want this software to be set to not start the machine, you have to do:chkconfig network-manager off This command, but by default chkconfig This command is not installed , and use Apt-get to install the premise is you can Sisu network, and network normal!

2. In addition, as long as Network-manager this program is running, the content you add to/etc/resolv.conf will disappear after a reboot, which means that your DNS configuration is invalid, which could result in the inability to sisu the network!

In order to use Network-manager, do not manually set the ETH0 network address in the file/etc/network/interfaces, as I do, keep the content as follows:

[Plain] view plaincopy650) this.width=650; "src=" Https://code.csdn.net/assets/CODE_ico.png "width=" 12 " Height= "alt=" on code to view the chip "style=" Border:none; "/>650" this.width=650; "src=" Https://code.csdn.net/assets/ico _fork.svg "width=" height= "alt=" derived from My Code slice "style=" border:none; "/>

2. [[email protected] #4] $CAT interfaces

4. # This file describes the network interfaces available on your system

6. # and how to activate them. For more information, see Interfaces (5).

10. # The Loopback network interface

12. Auto Lo

14. Iface Lo inet Loopback

Next, you can open Network-manager to configure the network,

650) this.width=650; "src=" http://img.blog.csdn.net/20140901224727402 "style=" border:none; "/>

650) this.width=650; "src=" http://img.blog.csdn.net/20140901224914277 "style=" border:none; "/>

Because I have successfully added, so the window title in the picture is "edit", if it is added for the first time, I believe it should show "add".

This configuration, each boot, Network-manager will be set by your network parameters set to the system, but also easy to modify.

The network configuration added through Network-manager is also in the system as a file, see my running situation:

[Plain] view plaincopy650) this.width=650; "src=" Https://code.csdn.net/assets/CODE_ico.png "width=" 12 " Height= "alt=" on code to view the chip "style=" Border:none; "/>650" this.width=650; "src=" Https://code.csdn.net/assets/ico _fork.svg "width=" height= "alt=" derived from My Code slice "style=" border:none; "/>

2. [[email protected] #8] $CD networkmanager/

4. [email protected] #9] $ls

6. networkmanager.conf VPN DISPATCHER.D dnsmasq.d system-connections

8. [email protected] #10] $pwd

10. /etc/networkmanager

12. [email protected] #11] $ls

14. networkmanager.conf VPN DISPATCHER.D dnsmasq.d system-connections

16. [[email protected] #12] $CD system-connections/

18. [email protected] #13] $ls

20. Wired

22. [[email protected] #14] $cat Wired

24. Cat:Wired:Permission denied

26. [email protected] #15] $sudo cat Wired

28. [sudo] password for zcm:

30. [802-3-ethernet]

32. Duplex=full

34. Mac-address=00:0c:29:2d:ef:be

38. [Connection]

40. Id=wired

42. Uuid=bad1acb0-b4dc-4da9-b2cd-d20adf930bca

44. Type=802-3-ethernet

46. timestamp=1409583499

50. [IPv6]

52. Method=auto

56. [IPv4]

58. Method=manual

60. dns=192.168.1.1;

62. addresses1=192.168.1.79;24;192.168.1.1;

64. [Email protected] #16]$

The content in this file is exactly the same as the settings you made through the Network-manager interface. "Wired connection 1" In my diagram has been changed to "Wired".

Most of the solutions mentioned on the Web are directly modifying the/etc/network/interfaces file and adding DNS to the/etc/resolv.conf, but the premise is that there is no network-manager involved , Factor they use the version may be ubuntu-server version, this version is no graphical interface, so naturally there is no Network-manager program, so that the setting will take effect, and can be maintained after a reboot.
