msg Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this

Question

Hi Guys,

I am trying to ping all the managed nodes using Ansible, but it is showing me the below error.

 "msg": "Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this.  Please add this host's fingerprint to your known_hosts file to manage this host."

Answer 1

Hi@akhtar,

You are getting this error because when we do SSH in the remote system it will ask yes or no. But Ansible doesn't have the capability to ask this in run time. So you need to disable host_key_checking in your ansible.conf file as shown below.

[root@localhost ~]# vim /etc/ansible/ansible.cfg
[defaults]
inventory = /etc/hostfile.txt
host_key_checking = False

Answer 2

vi /etc/ansible/ansible.cfg

[defaults]
host_key_checking = false
