Generate Ssh Key And Add To Remote Server
To be able to create SSH tunnel to that remote server you need to give your local server SSH access. You need to generate a key (or just use the existing one if you have) using ssh-keygen command. Before adding a new SSH key to the ssh-agent to manage your keys, you should have checked for existing SSH keys and generated a new SSH key. When adding your SSH key to the agent, use the default macOS ssh-add command, and not an application installed by macports. If you want to setup SSH keys to allow logging in without a password, you can do so with a single command. The first thing you’ll need to do is make sure you’ve run the keygen command to generate the keys: ssh-keygen -t rsa. Then use this command to push the key to the remote server, modifying it to match your server name.
Create the RSA Key Pair
Store the Keys and Passphrase
Once you have entered the Gen Key command, you will get a few more questions:
You can press enter here, saving the file to the user home (in this case, my example user is called demo).
It's up to you whether you want to use a passphrase.
Entering a passphrase does have its benefits: the security of a key, no matter how encrypted, still depends on the fact that it is not visible to anyone else. Should a passphrase-protected private key fall into an unauthorized users possession, they will be unable to log in to its associated accounts until they figure out the passphrase, buying the hacked user some extra time. The only downside, of course, to having a passphrase, is then having to type it in each time you use the Key Pair.

The entire key generation process looks like this:
Git Add Ssh Key
The public key is now located in /home/demo/.ssh/id_rsa.pub
The private key (identification) is now located in /home/demo/.ssh/id_rsa
Copy the Public Key
Once the key pair is generated, it's time to place the public key on the virtual server that we want to use.
You can copy the public key into the new machine's authorized_keys file with the ssh-copy-id command. Make sureto replace the example username and IP address below.
Alternatively, you can paste in the keys using SSH:
No matter which command you chose, you should see something like:
Now try logging into the machine, with:
and check in:
to make sure we haven't added extra keys that you weren't expecting.
Now you can go ahead and log into user@12.34.56.78 and you will not be prompted for a password. However, if you set a passphrase, you will be asked to enter the passphrase at that time (and whenever else you log in in the future).
Disable the Password for Root Login
Ssh Add Host
/generate-random-aes-key-swift.html. Once you have copied your SSH keys unto your server and ensured that you can log in with the SSH keys alone, you can go ahead and restrict the root login to only be permitted via SSH keys.
In order to do this, open up the SSH config file:
Within that file, find the line that includes PermitRootLogin and modify it to ensure that users can only connect with their SSH key:
Ssh Key Add Remote
