求助..无法获取IP

[wu1990]

学校宿舍

windows下
adsl拨号后出外网，不拨号的话自动获取IP只能进内网。

ubuntu下
不拨号获取不到IP了。。手动IP是不行的（试过，我从win下获取IP然后ubuntu下手动IP都不行）。。。。

不知道扫描原因。。

ubuntu有图形化的界面的配置方法

用dhclient命令能成功获取IP么？

当然也可以修改/etc/network/interfaces文件
一个典型的自动获取IP的文件内容应该是这样的

代码： 全选

# 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

你是不是校园网什么的啊

[wu1990]

是，但是却是用电信adsl出外网。。

win7里vmware转个ubuntu,桥接确又可以获取到IP...

彻底晕掉

网络和你用什么系统关系不大吧
