Linux System Administration
SSH - Secure Shell
SSH-Agent
It can be a pain to have to enter your password every time you use one of these commands.
We can configure OpenSSH so we do not have to enter a password each time we try to connect to a remote system.
Here is what we need to do:
Generate a personal authentication key.
Place the public part of the key on the remote server.
Keep the private part of the key on the local client.
When you try to connect to the remote system, the system issues a challenge based on the public key.
The private part of the key is required to respond properly to the challenge.
When the local system provides the proper response, the remote system logs you in.
