ubuntu 14.10上的网络错误

Question

我有一个ubuntu14.10服务器，它需要很长时间才能启动，当它启动的时候，它没有使用网络(它给了我很长的启动延迟)。dmesg | tail给

[  225.013622] init: networking pre-start process (1401) terminated with status 1
[  225.015451] init: networking post-stop process (1405) terminated with status 100
[  228.512454] init: networking pre-start process (1415) terminated with status 1
[  228.514132] init: networking post-stop process (1419) terminated with status 100

谷歌一下，这个问题似乎与文件/etc/网络/接口有关，以下是文件的内容：(em1是唯一以太网接口的名称)

# 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 em1
iface em1 inet DHCP

# This is an autoconfigured IPv6 interface

我必须连接显示器和键盘，输入ifconfig em1; dhclient em1才能正常工作。太不方便了。有什么想法吗？谢谢。

我认为你应该将"DHCP“改为"dhcp”：

# 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 em1
iface em1 inet dhcp

# This is an autoconfigured IPv6 interface

并重新启动网络：

sudo /etc/init.d/networking restart
