ubuntu连不上网啊，求大神相助

[宿命就是命]

试过ubuntu12.10和12.04服务器版本的，ping不到网关，unreachable。以前装过有图形界面的版本，一设置就连上网了。我的是静态IP地址的。我装的是双系统的，win7就好好的能上网，ubuntu就折腾了n天，实在是没辙了，网上查了很多，按照正常的方式都设置过，没用。自己觉得仍然有疑点的地方，一个是可能ubuntu内部装了防火墙，一个可能是网卡驱动没装，不过我ping过127.0.0.1，能通，网上说这说明网卡没问题。
我好歹也算个初学者吧，我是搞建模计算的，不是卖电脑硬件设备的，更不是搞编程的，不至于为了联网把这些全都学精通了吧？嗯？
现在实在是不知道问题出在哪了，求神人相助！

试试用Wubi安装，能上的了网吗？
或者把Windows的互联网设置用记录下来，然后储存成文本文件，然后转到Linux一步一步调试。
还有：为什么装Server版，而不是适合一般电脑的Desktop版？

[j0ven]

先备份一下interfaces文件
以前在网上收集的：
网卡静态分配IP地址

　　$ sudo gedit /etc/network/interfaces

　　# 修改文件/etc/network/interfaces如下文

　　#-------------------------------------------------------------------------------

　　# 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（配置环回口）

　　auto lo # 开机自动激lo接口

　　iface lo inet loopback # 配置lo接口为环回口

　　# The primary network interface （配置主网络接口）

　　auto eth0 #开机自动激活eth0接口

　　iface eth0 inet static #配置eth0接口为静态设置IP地址

　　address 192.168.1.10

　　netmask 255.255.255.0

　　network 192.168.1.0

　　broadcast 192.168.1.255

　　gateway 192.168.1.1


然后设置DNS服务器
echo "nameserver 8.8.8.8" > /etc/resolv.conf

然后重启下网络（或者重启机器）
sudo /etc/init.d/networking restart
下边这个也许有用

我是用U盘安装的，我的电脑很高端，搞理论计算需要高配置，server版应该比desktop版更强大吧，我主机的机箱就是个服务器的。我目前装的64位的都只有终端形式。现在的当务之急是连不上网，如果能连上网，什么版本都行。但别告诉我是用什么虚拟机之类的，那样会让计算性能大大降低的。我学长说凡是有图形界面的版本，那种的性能就不高，不能用来搞计算。
以前装过desktop版的，桌面形式的，连上网了，但是是32位的，所以不行。
用过wubi安装的，现在安装系统没问题。

楼上的那些设置还不如我直接重装系统在那里填网络设置来得快，重装填过很多次了，不应该是填的设置出了问题，况且同一台机子上的win7就能正常上网，所以我想很可能是别处的问题。我这是买的新电脑，专门搞计算的，什么硬件软件都是新安装的，所以可能有遗漏的地方。我希望能通过一些命令检测逐渐缩小和排除问题的范围，具体我该怎么做啊？

[hunter108]

lspci
ifconfig

把相关信息发上来。。。。

[宿命就是命]

终端形式下怎么截图啊？PrintScreen？保存在哪里？

[hunter108]

终端形式下，都是文字，直接选中，右键中“复制”。。。。

[宿命就是命]

刚才我输入service network status
显示network:unrecognized service

[宿命就是命]

刚才我输入service network status
显示network:unrecognized service

[hunter108]

/etc/init.d/networking status
service networking status

以上二种方式都可以。。。我喜欢第一种，因为我记不住服务名字全名，记个大概。。。而用第一种可以用tab键补全

[宿命就是命]

选中不了啊，在终端形式下，又没鼠标，怎么全选，复制，粘贴到哪？txt吗？我看到网上有截图的，难道那是桌面版吗？
楼上的想说明什么啊？我显示出的那个命令是不是说我什么东西没装上啊？

[hunter108]

不好意思忘了你在纯终端下。。。不过你是直接在主机上 登陆的？如果只 有纯终端可以lspci > txt.file 形式把输出内容保存到文件txt.file中，再把文件copy出来，网上有截图可能是从其他主机ssh上去的，比如从winxp上用secureCRT等软件ssh上去，然后就可以在secureCRT中复制相关内容，当然也可以截图，因为本来就在winxp中嘛，还有那个network，ubuntu中那个服务名字叫"networking"，不是"network"

你主机上是不是有二块网卡？，如果有第二块网卡，把网线接到另一网卡上，ping下网关看一下能通不？
