Host Unreachable

[Debojit]

Hi,

I'm running this on macOS 10.12.5, python 2.7.13, ansible 2.3.0.0. I get this error when I try to run the playbook:

$ ansible-playbook playbook.yml -i hosts --ask-pass --become -c paramiko
SSH password:

Hi ,
Facing the same issue : For traceability , I have added the Raspi's ip address in Hosts file, updated the wpa_supplicant.conf file and ran the command. Am I missing something?

[Nishanth-R]

Figured out what the Issue was , Raspbian switches off SSH by default now and hence this project wont work until you connect to peripherals and enable ssh.

You can just add an ssh file to the boot path

If you want to enable SSH, all you need to do is to put a file called ssh in the /boot/ directory. The contents of the file don’t matter: it can contain any text you like, or even nothing at all. When the Pi boots, it looks for this file; if it finds it, it enables SSH and then deletes the file.

the guide that @davidnquach posted worked for me regarding the connection failure, but now I'm getting this error:

{"changed": false, "msg": "host key mismatch for 192.168.1.xxx", "unreachable": true}

Any idea how to rectify this?

I'm not sure what to enter for the SSH Password and SSH Key for your new device prompts.

@Marto32

If this is your first time setting up; the default user is pi, and the password is raspberry.

Thanks @davidnquach. I think the problem is the ssh key prompt. What do you enter for please enter the SSH Key for your new device::?

I've tried blank and the one from my known_hosts file but I keep getting this error now:

fatal: [192.168.1.xxx]: UNREACHABLE! => {"changed": false, "msg": "Authentication failed.", "unreachable": true}

[davidnquach]

I don't believe I have run into that but have you generated an ssh key for your local machine? Also how are you running the ssh command? ssh [email protected] should just prompt you for the password and another prompt for you to agree that it is a safe machine to log into.

Got it working - thank you!
