- Sep 06, 2019 Keys can also be distributed using Ansible modules. The opensshkeypair module uses ssh-keygen to generate keys and the authorizedkey module adds and removes SSH authorized keys for particular user accounts. SSH key pairs are only one way to automate authentication without passwords.
- Nov 30, 2018 Sample set up for our RHEL 8 server. Where, You generate a key pair on your Linux/Unix/macOS desktop. Place the public key on RHEL 8 server. One can unlock public key using a private key stored on your desktop with the help of ssh command.

- I want to add a user to Red Hat Linux that will not use a password for logging in, but instead use a public key for ssh. This would be on the command line.
- You have recently installed Bitvise SSH Server.
- You have configured the SSH Server for access using SFTP, for Git access, or another purpose.
- You have installed Bitvise SSH Client on the computer from which you wish to connect.
- You wish to configure public key authentication between the SSH Server and Client.
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.
Before you configure public key authentication, it is important to understand:
- Public keys, in the way they are commonly used in SSH, are not X.509 certificates.
- Client authentication keys are separate from server authentication keys (host keys).
- A keypair consists of a private key and a public key, which are separate.
- A private key should never be sent to another party. It is private.
If this is the first time you are using public keys, we recommend the page Public keys in SSH.
Ssh Generate Key For User List
To use public key authentication, the client from which you are connecting needs to have a public/private keypair. To generate a keypair using Bitvise SSH Client, run the graphical SSH Client, and open the Client key manager:
Press the Generate button to generate a new keypair:
Guidelines:
Unless required for compatibility reasons, do not generate a DSA keypair. Only 1024-bit DSA keys are interoperable in SSH, and this key size is no longer considered adequate when using the DSA algorithm. Generate either an ECDSA keypair, or an RSA keypair of size 2048 bits or larger.
If you have saved a named SSH Client profile, the keypair generation interface will offer to store the keypair either in the profile, or globally.
When the keypair is stored globally, it is stored in the Windows registry for the current user, under HKCUSoftwareBitviseKeypairs.
It may be useful to store the keypair in a profile if the profile is going to be used on other computers, or by a job that runs as a different Windows account on the same computer. In SSH Client versions 7.xx and higher, the setting Sensitive information accessibility on the Login tab controls whether a keypair stored in the profile can be read by another Windows user, or on another computer.
You can choose a passphrase with which to protect the keypair. If you enter a passphrase, you will need to provide it every time the keypair is used for authentication.
Before you can use public key authentication, the public key for the keypair you have generated must be configured in the SSH Server. If you are able to connect to the SSH Server using password authentication, you can connect to the server and upload the public key using the Client key manager:
If the SSH Server does not allow you to connect using password authentication, or does not allow you to upload the key, you will need to send the public key to the server administrator using an alternate method of communication. To do this, export the public key using the Client key manager:
For help with importing the public key into Bitvise SSH Server, check the Public Key Authentication section of our SSH Server Usage FAQ.
Once the public key has been uploaded or imported for your account in the SSH Server, configure the SSH Client to enable public key authentication on the Login tab:

You should now be able to connect to the SSH Server using your public key:
Save the profile to preserve this configuration.
Our goals in this video are:
- Create a user
- Setup key-based login for the user
- Disallow root user login
Create a User
Let's create a new user and then setup some security.

Setup SSH Key Authentication
We can re-use the SSH key we created to allow us to log in as user root.
On our Mac, we can get the public key into our clipboard again:
Then over in the server, add that public key to user fideloper's authorized_keys file:
Disallow Root Login
First, we want user fideloper to be able to use sudo commands, so we don't need the root user to perform administrative tasks.
Sudo user
We can do this easily in Ubuntu by adding the user fideloper to the group sudo or admin (More explanation on that within the video). Ashampoo burning studio 12 key generator and activator.
Then log out, and log back in as user fideloper and you'll be able to use sudo commands.
Next, let's secure our server further and disallow root login.
Configure SSH
Now that user fideloper can do administrative tasks (things requiring super user access), let's edit the SSH daemon configuration to change this.
We'll do two things:
- Disallow password based authentication
- Disallow root user login
Do to that, we update the file /etc/ssh/sshd_config and change the following:
Then restart the SSH daemon:
And you're all set!
