VMWare 上的 Ubuntu 17 - 网络工作正常,突然不行。尝试了桥接和 NAT 无济于事,所以我正在考虑 linux 方面。
$ ifconfig -a
ens33: flags=4098<BROADCAST,MULTICAST> mtu 1500

在我看来,该接口已被禁用:
$ ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: ens33: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether 00:0c:29:f8:f7:47 brd ff:ff:ff:ff:ff:ff
但ifup
似乎不知道ens33
(或eth0
):
$ ifup ens33
Unknown interface ens33
$ ifup eth0
Unknown interface eth0
答案1
好吧,看来该界面并不“存在”。
将以下行添加到/etc/network/interfaces
:
iface ens33 inet dhcp
打开它(启用它):
sudo ifup ens33
好去吧:
ping google.com
耶!
