能ping,能上pldgin，能发email，但是不能wget,apt-get和上网页

kymlon

求救：什么问题？怎么解决~~
用IP也登陆不了网页，应该不是DNS的问题吧？

偶尔能打开网页 。。。偶尔掉线的人飘过

kymlon

对了，前几天更新路由了~有关系吗？

1）.  ifconfig结果如下：
eth0      Link encap:Ethernet  HWaddr 00:134:3C:85:1D  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

2）. /etc/host.conf文件内容为:

# The "order" line is only used by old versions of the C library.
order hosts,bind
multi on

3）.  /etc/resove.conf文件内容为：

search domain
nameserver 202.103.24.68
nameserver 202.103.44.150

4）.  /etc/network/interfaces内容为：

auto lo
iface lo inet loopback



iface eth1 inet dhcp

auto eth1


5）.这是我ping百度的结果：
wrante@wrante:~$ ping www.baidu.com

请大家帮忙啊~~重装了系统还是上不了网啊~是不是路由器的原因啊？

bufferfly

从现象上看，所有基于 http 协议的应用都不行。

难道往外连的 80 端口被禁止了？

kymlon

80端口被禁了？我也这样想啊~~
但是我的两个linux系统同时不能上网了，以下是：netstat -s的结果：
