您好,这是我的ifconfig输出：

如您所见,eth0下没有数据包.如果我尝试监视以太网活动,那么图表根本就没有做任何事情.如果我尝试使用wifi它工作得很好.

我连接到互联网的方式是：路由器 – >开关 – >我的以太网端口.我正在运行Xubuntu 14.04.

编辑：

ip route：

default via 10.0.0.138 dev eth0  proto static 
10.0.0.0/24 dev eth0  proto kernel  scope link  src 10.0.0.6  metric 1 

路线：

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         10.0.0.138      0.0.0.0         UG    0      0        0 eth0
10.0.0.0        *               255.255.255.0   U     1      0        0 eth0

我可以ping 10.0.0.138

解决方法:

好这个问题的解决方案是将内核从3.13升级到3.14.

非常感谢@garethTheRed带领我解决这个问题.
