Setting up passwordless authentication

About this task

You can set up passwordless authentication from the management machine to other machines where PingIntelligence components are installed.

On the management machine, run the following command.

The management machine is the machine from which the automated deployment script is run to deploy the various PingIntelligence software.
```
# ssh-keygen -t rsa
```
Result:

This command generates the ssh-keys.
Accept all the default options. Make sure that you do not set the password for the key.
You have two options for configuring passwordless authentication:

Choose from:
- Run the ssh-copy-id command for each host machine but not the management machine:
  # ssh-copy-id pi-user@<ping-machine IPv4 address>
  For example (ping-ase):
  ssh-copy-id pi-user@192.168.11.148
- Copy and add the ssh-keys manually:
  1. Fetch the generated key in step 1 from /home/$USER/.ssh/id_rsa.pub.
  2. Copy the key and add it to the /home/$USER/.ssh/authrorized_keys file on all the host machines where PingIntelligence components are installed.
    
    If configuring passwordless authentication does not succeed, contact your system administrator.
