Generating an SSH key pair using OpenSSH

You can generate an SSH key pair using OpenSSH.

Set up an RSA key pair on the AIX or Linux host and the clustered system:

Create an RSA key pair by issuing a command on the host that is similar to this command:
```
ssh-keygen -t rsa
```
You can also create a valid ECDSA key pair for authentication:
```
ssh-keygen -t ecdsa
```
Tip: Issue the command from the $HOME/.ssh directory.
This process generates two user named files. If you select the name key, the files are named key and key.pub. Where key is the name of the private key and key.pub is the name of the public key.
Associate the public key with a user on the clustered system using the management GUI.
