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

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

I had some trouble with this on my Ubuntu 18.04, which uses netplan instead of /etc/network/interfaces

Instead, I modified /etc/netplan/50-cloud-init.yaml to the following (The 192.168.99.2 is the static IP address I chose.)

network:
    ethernets:
        enp0s3:
            dhcp4: true
        enp0s8:
            dhcp4: no
            addresses: [192.168.99.2/24]
    version: 2

After editing the file, run

sudo netplan try

That will allow you to verify it's working before changing the virtual machine's network settings.

@bigjoe2000 is correct. Just a add on to this: use tab in yaml file.

Are you doing on the VM's Settings or the VirtualBox preference? When I do an "+" I'm only seeing a new NAT connection created. Thanks!

When I'm trying to ssh in on my host, I'm asked for a password. Neither the host nor the guest pw will work, any idea?

Nice

VirtualBox UI had been redesigned, the UI for step #1 had been moved to File > Host Network Manager.

I'm not sure which version this change was introduced into, perhaps long time ago? I'm on v6.1.16 for MacOS.

End-to-end, enabling connection from MacOS to hosted RHEL8 in VirtualBox 6.1

In VirtualBox (6.1.x):
- File > Host Network Manager ...
- Create (vboxnet0)

For the particular instance of VM (powered off):
- Settings > Network > Adapter 2
- Enable Network Adapter (checked)
- Attached to: Host-only Adapter
- Name: vboxnet0

Start the VM and login as root:
# nmcli dev status
	// Will show that enp0s8 is down
# nmcli con up enp0s8
# nmcli dev set enp0s8 autoconnect yes managed no
# nmcli dev connect enp0s8
# nmcli dev status
	// Will show that enp0s8 is connected
# ifconfig
	// Shows an inet IP address (192.168.56.101)

From the host (Terminal on MacOS):
$ sudo vim /etc/hosts
		*****
		192.168.56.101  vbox.rhel8
		*****
	:wq
$ ping -c 3 vbox.rhel8
$ ssh-copy-id jubilee@vbox.rhel8
$ ssh jubilee@vbox.rhel8 (using SSH keys, passwordless)

When I'm trying to ssh in on my host, I'm asked for a password. Neither the host nor the guest pw will work, any idea?

I am getting permission denied when i try to log in. What password should i be trying? Thanks!

I had the same problem. The reason was: I used "root" user. So, I had added 2 lines into sshd_config (in VM):

PermitRootLogin yes
PasswordAuthentication yes

and then (in VM terminal)
systemctl restart sshd
