Ubuntu Ethereum main network

1. The description is not very clear
I don't understand your purpose

eth0 is the device name. Eh0 is connected to an Ethernet network

if you mean you can't connect to the Internet
it depends on the network condition of your home
if you want to use PPOE, you can click on the link to change the configuration of the linked device, and you need to enter the password you set at the time of installation. Then add PPOE

2.

See the article:

< pre t = "code" L = "HTML" > http://www.yyearth.com/article/14-04/network.html

3. There is a space in the middle: ifconfig-a network card name is not necessarily eth0, it may be other name. If you don't see the network card, it means that the system doesn't recognize it, and you need to install another driver

4. You want a network card device, right
/ etc / network / interfaces
sudo VI / etc / network / interfaces
you can edit it and replace the line about eth0 with the following line:
? The primary network interface - use DHCP to find our address
auto eth0
Iface eth0 INET DHCP

use the following command to make the network settings effective:
sudo / etc / in It.d/networking restart
you can also directly enter the following command from the command line to get the address

5.

The network configuration files of Ubuntu mainly include: IP address configuration file, host name configuration file and DNS configuration file. The solution is as follows:

1. First check the initial network state

6. 如果ethtool eth0显示的信息类似与下面Settings for eth0:Supported ports: [ TP ]Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/FullSupports auto-negotiation: YesAdvertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full说明eth0是千兆网卡，如果ethtool eth0显示的信息类似与下面Settings for eth0:Supported ports: [ TP ]Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/FullSupports auto-negotiation: YesAdvertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full说明eth0是百兆网卡对网络进行设置，可以编辑vi /etc/network/interfaces,类似与下# This file describes the network interfaces available on your system# and how to activate them. For more information, see interfaces(5).# The loopback network interfaceauto loiface lo inet loopbackauto eth0 #设置eth0iface eth0 inet static address 192.168.37.76 netmask 255.255.255.0 network 192.168.37.0 broadcast 192.168.37.255 gateway 192.168.37.254 dns-nameservers 192.168.37.254 #auto eth1 #设置eth1#iface eth1 inet static#address xxx #auto eth0:1 #单网卡设置多个IP#iface eth0:1 inet static#address 192.168.1.60#netmask 255.255.255.0#network x.x.x.x#broadcast x.x.x.x#gateway x.x.x.x设置完后重启网络/etc/init.d/networking restart

7. $ ifconfig eth0 | sed -r -n 's/.*inet addr:(\S+).*Mask:(.*)/\1 \2/p'

8. Unknown_Error

9. Intel HD integrated graphics card also depends on what model, but generally speaking, it's not comparable. You can see the ladder diagram of graphics card
260 is just a little bit better. Second hand card 20 yuan is excusable.
