SSH Connection Failure in Ansible
Solution: To resolve this error, please follow the following steps below
– Ensure the inventory file is configured properly and ensure that the “ansible_connection=winrm” is included in your inventory. Domain authentication requires using krb5. On how to configure kerberos, see the following article https://techdirectarchive.com/2020/03/14/configuring-kerberos-for-ansible-authentication/
[win] 192.168.178.43 [win:vars] ansible_user=administrator ansible_password=xxxxxxxxxxx ansible_port = 5986 ansible_connection=winrm ansible_winrm_server_cert_validation=ignore
When this is configured correctly, the following error will disappear.
– Configure the remote host system to connect with the Ansible Control node(SSH Connection Failure in Ansible). This will permit the connection between the Windows host system and the Ansible server.
