Hi,
I have just installed Ansible for the first time and am attempting to
connect to a Cisco switch, this needs to be with username and password.
>From both an Ubuntu server and my Mac I can ssh to the box with the same
username and password I have configured in the ansible inventory.
I have attempted from an Ubuntu host and my Mac, however I am receiving the
following error:
===
:/etc/ansible$ ansible -m ping all
| UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh: Connection to 192.168.10.200
closed by remote host.\r\nConnection closed\r\n",
"unreachable": true
}
===
Ansible config:
host1 ansible_host=192.168.10.200 ansible_user= ansible_ssh_pass=
Debug from switch shows the succesful authentication and subsequent closing
of the connection:

Using a playbook:
:~/ansible/playbooks$ ansible-playbook tst.yml
PLAY [testdevices]
TASK [Gathering Facts]
fatal: [host1]: UNREACHABLE! => {"changed": false, "msg": "Failed to
connect to the host via ssh: Connection closed\r\nConnection to
192.168.10.200 closed by remote host.\r\n", "unreachable": true}
to retry, use: --limit @/home/exinadmin/ansible/playbooks/tst.retry
PLAY RECAP
: ok=0 changed=0 unreachable=1 failed=0
Any help will be greatly appreciated !
Phil.
