我刚刚Ubuntu 16.04
在一台机器上安装了最新版本VirtualBox
。我想拥有两个不同的网络接口:
- 第一个使用 ssh 从主机访问客户机;为此,我安装了适配器
Host-only Adapter
1 - 第二个能够从主机连接到互联网,所以我安装了一个基本的
NAT
适配器 2
但是,即使两个网络适配器都被正确识别,也只有第一个可以访问。
$ ls /sys/class/net/
enp0s3 enp0s8 lo
$ ifconfig
enp0s3 Link encap:Ethernet HWaddr 08:00:27:47:52:7b
inet addr:192.168.56.101 Bcast:192.168.56.255 Mask:255.255.255.0

我怎样才能让系统也识别第二张卡?
答案1
我已经解决了添加的问题
# The secondary network interface
auto enp0s8
iface enp0s8 inet dhcp
到/etc/network/interfaces
(使用 获取新接口名称ifconfig -a
)
并使用 重新启动网络sudo service networking restart
。
现在,这是结果
$ ifconfig enp0s3 Link encap:Ethernet HWaddr 08:00:27:47:52:7b
inet addr:192.168.56.101 Bcast:192.168.56.255 Mask:255.255.255.0

答案2
Ubuntu Server 的新版本使用netplan
而不是ifup
。
您必须编辑/etc/netplan/00-installer-config.yaml
:
network:
ethernets:
enp0s3:
dhcp4: true
enp0s8:
dhcp4: true
version: 2
然后运行:
netplan apply
然后它就会弹出!
