SSH between Mac OS X host and Virtual Box guest

gistfile1.md

On Mac OS (host):

Shutdown your VM and do:

VirtualBox > Settings > Network > Add (you will get vboxnet0)

On a terminal ifconfig will show you new interface vboxnet0

VM's Settings > System > check "Enable I/O APIC." VM's Settings > Network > Adapter 2 > host-only vboxnet0

On Ubuntu (guest):

Install OpenSSH Server

$ sudo apt install openssh-server

Since 17.10

First: create /etc/netplan/02-netcfg.yaml file to append the following lines:

network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s8:                             // `ip address` will show three adapter: lo, enp0s3, enp0s8. enp0s3 is the NAT adapter with ip 10.0.2.15/24(maybe different on your vm), so enp0s8 is the host-only adapter
      addresses:
              - 192.168.99.200/24       //you can change this static ip by yourself
      dhcp4: no

then:

$ sudo netplan generate
$ sudo netplan apply

Older version

Edit /etc/network/interfaces file to append the following lines:

auto eth1
iface eth1 inet static
address 192.168.56.10
netmask 255.255.255.0

Run sudo ifup eth1 from the Ubuntu command line. SSH server should be up and running. Switch to your host terminal and enter ssh 192.168.56.10
