更改默认以太网卡

更改默认以太网卡

我有一个 Ubuntu Server 14.04 和 2 个以太网卡。

我现在只使用 eth1,所以我想更改我的配置,因为我现在无法使用我的服务器访问互联网。

我已经更改了文件 /etc/network/interfaces

# The primary network interface for Internet
auto eth1
iface eth1 inet static
        address 192.168.1.254
        network 192.168.1.0
        netmask 255.255.255.0
        broadcast 192.168.1.255
        gateway 192.168.1.1
        dns-nameservers 109.88.203.3,62.197.111.140

# The secondary network interface for local network
auto eth0
iface eth0 inet static
address 192.168.0.201
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255
dns-nameservers 192.168.1.254

我还更改了文件 /etc/dhcp/dhclient.conf 并添加了以下行:

supersede routers 192.168.1.1

如果我跑

ping 8.8.8.8

有用

PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

rtt min/avg/max/mdev = 18.238/19.803/21.928/1.523 ms

但是当我运行 sudo apt-get update 时它不起作用:

W: Failed to fetch http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu/dists/precise/main/i18n/Translation-en  Something wicked happened resolving 'ppa.launchpad.net:http' (-5 - No address associated with hostname)

我能做些什么 ?

提前致谢。

没关系,

我修改了文件 /etc/network/interfaces

# The primary network interface for Internet
auto eth1
iface eth1 inet dhcp

现在可以了
