今天重裝了vmware後，再次使用原來的Ubuntu7.10文件，找不到網絡連接。
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
原來是新舊vmware的網卡不一樣，將eth0改為eth1，重啟網絡
sudo /etc/init.d/networking restart
一切OK了
順便講一下/etc/network/interfaces
如果是配置eth為靜態IP
（比如192.168.1.1）並且指定網關（如192.168.1.254），那麼如此配置：
auth eth0
iface eth0 inet staticaddress 192.168.1.1
netmask 255.255.255.0
gateway 192.168.1.254
如果是手動指定IP並且還需要訪問互聯網，比如wget下載，那麼還需要設置DNS：
$sudo pico /etc/resolv.conf向這裡添加配置內容：nameserver xxx.xxx.xxx.xxx保存即可。
