公司网络，在win7下可以正常链接网络，在ubu下显示链接上但打不开网页？

ubuntu11.04离线升级系统和安装软件[备忘录]
以mirrors.163.com为例
1，按照以下目录结构下载（wget下载时，自动生成相应目录结构）
natty/ 27-Apr-2011 13:28 -
natty-backports/ 12-Oct-2010 14:25 -
natty-proposed/ 04-May-2011 13:48 -
natty-security/ 04-May-2011 13:48 -
natty-updates/ 04-May-2011 13:48

wget.exe -e robots=off -r -x -np -k -A * http://mirrors.163.com/ubuntu/dists/natty/
wget.exe -e robots=off -r -x -np -k -A * http://mirrors.163.com/ubuntu/dists/natty-backports/
wget.exe -e robots=off -r -x -np -k -A * http://mirrors.163.com/ubuntu/dists/natty-proposed/
wget.exe -e robots=off -r -x -np -k -A * http://mirrors.163.com/ubuntu/dists/natty-security/
wget.exe -e robots=off -r -x -np -k -A * http://mirrors.163.com/ubuntu/dists/natty-updates/

或者（还没试过行不行）
wget.exe -e robots=off -r -x -np -k -A * -i 163.list

文件163.lst内容如下：
http://mirrors.163.com/ubuntu/dists/natty/
http://mirrors.163.com/ubuntu/dists/natty-backports/
http://mirrors.163.com/ubuntu/dists/natty-proposed/
http://mirrors.163.com/ubuntu/dists/natty-security/
http://mirrors.163.com/ubuntu/dists/natty-updates/

下面按照 viewtopic.php?t=87977
做就可以了。
2，下载完后，修改sources.list(先备份)
$sudo cp /etc/apt/sources.list sources.list_backup
$sudo gedit /etc/apt/sources.list

wget递归下载 参考
