网卡问题

aluocn

安装linux时只有一块网卡RTL8139C,后来又插上一块同型号的网卡,本机无法与网内机器通信.后检查发现,只用一块网卡情况下,原网卡换个槽,运行service network restar 就会有如下提示:
Bringing up loopback interface: 8139too device eth0 does not seem to be present, delaying initialization. [FAILED]
Bringing up interface eth0: 8139too device eth0 does not seem to be present, delaying initialization. [FAILED]

高手帮忙看看怎么解决啊,困扰多日了,郁闷中...

The problem lies in the fact that ethernet MAC addresses are cached. You need to remove a file to clear the cached value:

sudo rm /etc/udev/rules.d/70-persistent-net.rulesAfter a restart of your server you should have networking back again.
