用路由器上网Ubuntu无法连接但是虚拟机里的XP却可以连接?[已解决:重启路由器]

#1

帖子 zwdnet » 2010-12-01 20:31

我用的是Ubuntu10.04,内核2.6.36-1,电脑是华硕EeePC1000H。
我上网是在大学宿舍里面,通过路由器7个人共享上网的,之前网络正常,一插上网线就可以连上了,IP地址是192.168.1.103之类的。今天网上,我上着上着网,突然一下子就断线了,再手动连接连不上了。其他人的网络正常。于是我就重启,但是重启后仍然连接不上。在断线的当时,我是开了浏览器,开了pps在看电影,同时开了wget在下载东西,另外我在终端里用"sudo nmap -O"命令想试试百度谷歌他们用什么操作系统,百度的试了,刚把谷歌的敲进去执行网络就断了,就再也连接不上了。不知道跟这个有没有关系。
重启后还连接不上,这是syslog里的相关日志:

我就想开XP看看,于是启动了VirtualBox里的XP,没想到可以连接上的。我现在就是在虚拟机里的XP里发帖。windows的本地连接状态里的连接信息为:

再点详细信息为:

而我的/etc/network/interfaces的内容就两行:

代码: 全选

auto lo
iface lo inet loopback
我在网上找了下,发现这个帖子http://forum.ubuntu.org.cn/viewtopic.php?f=116&t=162276 照其意思,改成

代码: 全选

auto lo
auto eth0
iface lo inet loopback
iface eth0 inet dhcp
netmask 255.255.255.0
gateway 192.168.1.1
然后执行

再用鼠标左键单击托盘区的网络图标,选"Auto eth0",还是连接不上。
我没辙了,特来请教,还要设置哪里啊?谢谢了!

唉,搞来搞去,把/etc/network/interfaces恢复原状,浏览器里输192.168.1.1登陆路由器,重启路由器,连上了!
您好,请多关照!
