sudo apt update && sudo apt upgrade -y sudo apt install openssh-server -y NOTE: you may login from Windows to Ubuntu with: ssh localhost
General ideal of the setup[edit]
[ssh client] ----> [ssh relay server] ----> [ssh target server] your Windows modified authorized_keys target machine machine in your Ubuntu VM using cedar 'smart' 'ubuntu' 'cedar'
Login to the ubuntu VM and create a custom_ssh folder[edit]
jaime@ubuntu:~$ cat custom_ssh/sshd_config Port 2222 HostKey /home/jaime/custom_ssh/ssh_host_ed25519_key HostKey /home/jaime/custom_ssh/ssh_host_rsa_key AuthorizedKeysFile /home/jaime/custom_ssh/authorized_keys ChallengeResponseAuthentication no UsePAM no #UsePrivilegeSeparation no Subsystem sftp /usr/lib/openssh/sftp-server PidFile /home/jaime/custom_ssh/sshd.pid NOTE: you may copy the ssh_host keys from /etc/ssh
Customize .ssh/config on ubuntu[edit]
