Erratic SSH Connection

[Manoj Govindan]

Consider the following two commands:

(1) ansible-playbook --limit dtest  --private-key=/path/to/private/key.pem test_stat.yml

(2) ansible-playbook --limit dtest test_stat.yml

The test_stat playbook is given below:

# An ANSIBLE playbook to execute stat

- name: Play - Stat

  hosts: all

  vars_files:

    - "ssh_server_static_keys/{{ inventory_hostname }}.yml"

  roles:

    - stat

I have a file named ssh_server_static_keys/dtest.yml that contains something like this.

ssh_host_rsa_key: |

    -----BEGIN RSA PRIVATE KEY-----

    .....

    -----END RSA PRIVATE KEY-----

If I execute the commands (1), followed by (2), both work. 

Executing (1) creates a socket named $HOME/.ansible/cp/ansible-ssh-<something>

As long as that socket is alive, (2) works. 

If I execute (2) alone, it doesn't work. I get the following error:

fatal: [dtest] => SSH Error: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

    while connecting to <host>:<port>

However, (2) alone works without any error for *another* host, which has a key in ssh_server_static_keys/something.yml.

What am I missing? 

Thanks,

Manoj

No, unless I'm missing something, this is how ssh works. ControlPersist/Master allows you to reuse the connection so you don't need to re-authenticate. But if you never authenticated ... there is nothing to reuse.
