SSH server problem

[Gaetano]

I have installed mail in a box works perfect!!
Thank you very much for your big job.
In System Status Checks all is green only one is red and is that voice:
“ The SSH server on this machine permits password-based login. A more secure way to log in is using a public key. Add your SSH public key to $HOME/.ssh/authorized_keys, check that you can log in without a password, set the option ‘PasswordAuthentication no’ in /etc/ssh/sshd_config, and then restart the openssh via ‘sudo service ssh restart’.”

I have undertood that I have to insert the public key I have generated into “HOME/.ssh/authorized_keys”
Can I do using vim editor?
Can I do from another computer accessing my cloud server trough terminal?
Can you give me the command to use for editing that file?

Thanks in advance
Gaetano

Yes, and yes.

@Gaetano

With vi? No way … I use a much simpler and intuitive editor, nano.

You said that you generated the SSH keypair on your local system. Is you local system Windows or *nix based? If it is *nix based you simply use the ssh-copy-id command from the terminal.
