重装linux 连不上网,重装Vmware造成Ubuntu网络问题

今天重装了vmware后，再次使用原来的Ubuntu7.10文件，找不到网络连接。

web@Ubuntu8:~$ ifconfig

eth1 Link encap:Ethernet HWaddr 00:0C:29:ED:F3:C2

inet addr:0 Bcast:0 Mask:0

Interrupt:16 Base address:0x2000

lo Link encap:Local Loopback

inet addr:127.0.0.1 Mask:255.0.0.0

inet6 addr: ::1/128 Scope:Host

UP LOOPBACK RUNNING MTU:16436 Metric:1

RX packets:0 errors:0 dropped:0 overruns:0 frame:0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

sudo vim /etc/network/interfaces

# This file describes the network interfaces available on your system

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

# The loopback network interface

auto lo

iface lo inet loopback

# The primary network interface

auto eth0

iface eth0 inet dhcp

原来是新旧vmware的网卡不一样，将eth0改为eth1，重启网络

sudo /etc/init.d/networking restart

一切OK了

顺便讲一下/etc/network/interfaces

如果是配置eth为静态IP

(比如192.168.1.1)并且指定网关(如192.168.1.254)，那么如此配置：

auth eth0

iface eth0 inet staticaddress 192.168.1.1

netmask 255.255.255.0

gateway 192.168.1.254

如果是手动指定IP并且还需要访问互联网，比如wget下载，那么还需要设置DNS：

$sudo pico /etc/resolv.conf向这里添加配置内容：nameserver xxx.xxx.xxx.xxx保存即可。
