服务器评测
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

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。
