Procedure
Followed the procedure in Latest Releases Via Apt (Ubuntu) .
Resynchronize Package Index Files
The package index files were resynchronised with their sources as follows:
sudo apt-get -y update

Establish SSH Connectivity
After Ansible was successfully installed, SSH equivalency was established and Ansible was tested.
Establish SSH Credentials on AUBURN
The following command was used to establish SSH credentials on AUBURN :
ssh-keygen
The output was:
Generating public/private rsa key pair. Enter file in which to save the key (/home/douglas/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/douglas/.ssh/id_rsa. Your public key has been saved in /home/douglas/.ssh/id_rsa.pub. The key fingerprint is: SHA256:shjEH2qkzF+G4j+eNxAlULEyDUikdRuVVNH+HU10AmA douglas@auburn.yaocm.id.au The key's randomart image is: +---[RSA 2048]----+ |o++o=+ooooE.....o| |o. =.+o .. .o| |. o Bo. . o | | o *.+ . . . .| | = =.= S . . . | | . +.= o . . | | . o.. | | ...o | | .+o . | +----[SHA256]-----+
Propagate SSH Credentials to PENRITH
The following command was used to copy SSH credentials on AUBURN to PENRITH :
ssh-copy-id penrith.yaocm.id.au
The output was:

Propagate SSH Credentials to PENRITH
The following command was used to copy SSH credentials from AUBURN to PENRITH :
ssh penrith.yaocm.id.au
The output was:

Testing
Followed the procedure in Your first commands .
Establish Hosts Inventory
On AUBURN , the file /etc/ansible/hosts was set to contain the following:
# Client machines [clients] penrith.yaocm.id.au # Oracle RAC Nodes [oracle_rac] redfern1.yaocm.id.au redfern2.yaocm.id.au
Do PING Test
To test Ansible connectivity to the hosts, the following command was used:
ansible all -m ping
The output was:
redfern1.yaocm.id.au | SUCCESS => { "changed": false, "ping": "pong" } penrith.yaocm.id.au | SUCCESS => { "changed": false, "ping": "pong" } redfern2.yaocm.id.au | UNREACHABLE! => { "changed": false, "msg": "Failed to connect to the host via ssh: ssh: connect to host redfern2.yaocm.id.au port 22: No route to host\r\n", "unreachable": true }
