Once openssh-server package is installed in your Server, you can now see ssh service available under /etc/init.d directory. Now you can check the status of ssh service by using /etc/init.d/ssh status command as shown below.

Step 5: Login to Ubuntu 20.04 Using ssh Port 22

Now if you try to connect your Ubuntu 20.04 Server using ssh port 22 then you should be able to connect just like the way it is shown below.

In case if you are still not able to connect then i would suggest you to check and perform below steps :-

a) Check your /etc/ssh/sshd_config file and make sure Port 22 Line is uncommented there. If it is not uncommented, then you can uncomment it and restart the ssh service by using systemctl restart ssh or by using /etc/init.d/ssh restart command.

b) Make sure ssh is allowed from ufw firewall if you are running this firewall. If it is not allowed then you need to allow it and then try again to ssh the Ubuntu 20.04 Server. It should work.
