ssh-keygen . password-less SSH login.
SSH is often used to login from one system to another without requiring passwords.
A number of methods may be used for that to work properly, one of which is to setup a file (permission 600) with its content being the name of the remote system you trust, followed by the username your trust: cantin would mean you trust user cantin from to connect to your account, without requiring a password.
But for that to work, SSH itself must be configured to trust files (which it does not for most OpenSSH installations - but we do on most systems RCSG maintains), and the private/public key pair of each system must be properly set in the system-wide ssh_known_hosts public key file.
This, of course, requires help from the local systems administrator.
The second method does not require any help from the systems administrator. And it does not require modifications to the file. Instead, it requires you generate your own personal set of private/public pair.
ssh-keygen is used to generate that key pair for you. Here is a session where your own personal private/public key pair is created.
The command ssh-keygen -t rsa initiated the creation of the key pair.
No passphrase was entered ( Enter key was pressed instead.
The private key was saved in . This file is read-only and only for you. No one else must see the content of that file, as it is used to decrypt all correspondence encrypted with the public key.
The public key is save in.
In this case, the content of file is.
It is one line in length.
Its content is then copied in file of the system you wish to SSH to without being prompted for a password.
The example shown here generated keys on sodium by user cantin . If the public key generated, file . was copied to your account, file on . then user cantin@sodium is allowed to SSH into your own account on without the use of a password.
To summarize, a personal private/public key pair is generated using the ssh-keygen command. The public key is then copied onto a remote systems' file. And you can now SSH to the remote systems's account without the use of a password.
