I have just install Debian via VirtualBox in macbook, set NAT connection
between VM Debian and Host macOS.
So, if I need to remotely login VM Debian by macOS, macOS have to be the
SSH client, VM Debian have to be the SSH server, VirtualBox have to be the
SSH connection translation bridge.
Click VirtualBox logo and enter that, found out virtual machine OS
linux_Debian_11, single right click, choose and click Setting,than enter
linux_Debian_11 - General, choose and click Network, make sure your default
adapter 1 was NAT, and then click Advanced, click Port Forwarding
button, edit Guest Port to 22, edit Host Port to 22 or 22222, edit
Name to SSH, edit Host IP to 127.0.0.1, edit Guest IP to 10.0.2.15.
Just liking:
Name Protocol Host IP Host Port Guest IP Guest Port
SSH SSH 127.0.0.1 22222 10.0.2.15 22

In this SSH connections, VM Debian active as the SSH server. So, the VM Debian
Settings is that the SSH server setting.
No matter you are Debian or even Ubuntu, just use:
sudo apt update
sudo apt install openssh-server
Check out whether the server of SSH has opened:
ps -e | grep ssh
If you saw sshd, then the server of SSH was opening; Or, just use the code to
start the server of SSH:
sudo /etc/init.d/ssh start
Just set SSH port to 22 via comment the # before #Port 22 at
/etc/ssh/sshd_config, use VIM to open and edit via
sudo vim /etc/ssh/sshd_config, and edit that Port line to:
Port 22 # if set port forwarding at Host was 22, then -p do not need to write
Just use one of the codes to make sure the IP of VM/Guest Debian/Ubuntu and
keep it in mind: hostname -I; hostname -I | awk '{print $1}';
ip route get 1.2.3.4 | awk '{print $7}'.
E.g: hostname -I:
10.0.2.15
the IP was that you need to set that Guest IP at Step1:
VirtualBox Manager: Port Forwarding.

4.Chapter 6. Virtual Networking.
In this SSH connections, Host macOS active as the SSH client. So, the VM Debian
Settings is that the SSH client setting.
All modern Macs running macOS or Mac OS X come with SSH pre-installed by
default.
Just use the code to connect with VM Debian/Ubuntu:
ssh -p 22222 [email protected]
Then,you got:
The authenticity of host '127.0.0.1 (127.0.0.1)' can't be established.
ECDSA key fingerprint is SHA256:xxx.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '127.0.0.1' (ECDSA) to the list of known hosts.
[email protected]'s password:
then input my debian user password: my_debian_user_password, then got:
Linux device_Name X.YZ.Z-ZZ-amd64 #1 SMP Debian X.YZ.XYZ-X (20XX-0X-XX) x86_64

my_debian_user_name@device_Name:
Just exit to quit the remote login.
my_debian_user_name@device_Name:exit
logout
Connection to 127.0.0.1 closed.
We need togenerate a pair of RSA public/private key.
E.g: I just use ssh-keygen -t rsa -b 4096 -C "macos_login_debian_via_ssh" to
product a pair of RSA key store under /User/my_mac_usr_name/.ssh/ with name
macos_login_debian_id_rsa and macos_login_debian_id_rsa.pub.
And I push that public key to VM debian:
ssh-copy-id -p [email protected]
Or use this code to push the generated public key to VM debian:
ssh-copy-id -f -p [email protected]
Or just use this to push:
ssh-copy-id [email protected]
then you will see an new generated file name authorized_keys under your VM
debian /home/my_debian_user_name/.ssh, and the file authorized_keys's text
is that the generated public key macos_login_debian_id_rsa.pub's text.
Just use this code: eval "$(ssh-agent -s)"; That terminal prompt:
> Agent pid 59566.
3.3.2.2Configure SSH config file
cd && cd /Users/user_name/.ssh && vim config
Add the below to /Users/user_name/.ssh/config, save and active:
Host debian
Hostname 127.0.0.1
User my_debian_user_name
AddKeysToAgent yes
UseKeychain yes
IdentityFile /Users/my_mac_usr_name/.ssh/macos_login_debian_id_rsa
ssh-add -K /Users/my_mac_usr_name/.ssh/macos_login_debian_id_rsa
That terminal prompt: 4096 SHA256:.../Users/my_mac_usr_name/.ssh/macos_login_debian_id_rsa(RSA).
If you are using Zsh, just edit ~/.zshrc and add the below code line, and active
via source ~/.zshrc:
alias debian="ssh -p 22222 my_debian_user_name@debian"
Or if you are using Bash, just edit ~/.bashrc, add the below, and active
via source ~/.bashrc:
alias debian="ssh -p 22222 my_debian_user_name@debian"
Now, you could just use debian to remote login VM Debian in Macbook's terminal.

Running files on Cloud/VM Debian could use ssh command, while transmit files
on Cloud/VM Debian should be use scp command.
Write project on local host Macbook, run program in free remote cloud/VM Debian
via ssh the program to there. E.g: a program test.py under ~/ in my local
Macbook, just use this code to run in remote cloud/VM(e.g:Debian):
ssh -p port_target [email protected] python3 < ~/test.py
