新安装14.04服务器网络无法工作

Question

我刚刚安装了14.04服务器，安装程序能够连接到互联网来完成安装。但是，在安装结束时重新启动后，我无法连接到网络。安装程序无法自动设置网络连接，所以我已经手动设置了。现在，我不能在本地网络上打开路由器或任何其他计算机。有人对从哪里开始有建议吗？

这就是我的/etc/网络/接口文件的样子：

# 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 eth1
iface eth1 inet static
    address 192.168.0.9
    netmask 255.255.255.0
    network 192.168.0.0
    broadcast 192.168.0.255
gateway 192.168.0.1

这是eth1的输出：

这是sudo lshw -C网络的输出：

Answer 1

你确定你把网络电缆插上了吗？

UBUNTU基础安装为IPaddresses分配DHCP。除非在安装过程中，$USER分配了一个静态IPaddress。

从最初的岗位。

输出lshw -C network

*-网络:1个逻辑名称：eth1

输出ethtool eth1：

eth1的设置：

Link detected: no

1. 检查一下网络电缆。
2. 从shell提示符中输入命令ifconfig

“发布输出”。IPaddress, NETWORK, SUBNETMASK, GATEWAY, BROADCAST, DNS,

1. 从shell提示符中输入命令hostname -I

“发布输出”。

1. 登录到路由器/调制解调器/网桥并获得路由器的IPaddress, NETWORK, SUBNETMASK, GATEWAY (S)，假设你只有一个路由器？

发送路由器的“私有IPaddress, NETWORK, SUBNETMASK, GATEWAY__”。

注意：“移除”路由器的公共IP地址：X.X.X.X它可以在“我的IP地址”页面找到。(从连接到您的局域网的另一台计算机)

例如，如果您的家庭中有多台计算机，您可能希望在您的家庭内的每台计算机的私有IP地址。

路由器获取公共IP地址，连接到路由器的计算机、平板电脑和智能手机(通过有线或wifi)通过DHCP协议或静态分配从路由器或服务器获得私有IP地址。这超出了问题的范围。
