By default, your freshly installed system will have no SSH service enabled, which means you won’t be able to connect to it remotely using SSH protocol (TCP port 22), therefore installing SSH server will be one of the first post-install steps on your system…
OpenSSH installation
root@ubuntu:~# sudo apt-get install openssh-server
Verify your SSH Sever installation
root@ubuntu:~# ps -aef | grep sshdroot
