Facing the same issue. Following.

Can you launch the same command with the option -vvvv for more output. please !

Thanks.
From your output, I see that you don't have any ansible_user specified :

<35.165.79.66> ESTABLISH SSH CONNECTION FOR USER: None

Cat you show the content of your inventory file too ?

# This is the default ansible 'hosts' file.
#
# It should live in /etc/ansible/hosts
#
#   - Comments begin with the '#' character
#   - Blank lines are ignored
#   - Groups of hosts are delimited by [header] elements
#   - You can enter hostnames or ip addresses
#   - A hostname/ip can be a member of multiple groups

# Ex 1: Ungrouped hosts, specify before any group headers.

## green.example.com
## blue.example.com
## 192.168.100.1
## 192.168.100.10

# Ex 2: A collection of hosts belonging to the 'webservers' group

[webservers]
35.165.79.66

# If you have multiple hosts following a pattern you can specify
# them like this:

## www[001:006].example.com

# Ex 3: A collection of database servers in the 'dbservers' group

## [dbservers]
## 
## db01.intranet.mydomain.net
## db02.intranet.mydomain.net
## 10.25.1.56
## 10.25.1.57

# Here's another example of host ranges, this time there are no
# leading 0s:

## db-[99:101]-node.example.com

ssh [email protected] connection will establish. but ansible command not able to complete.

Good,
It's a bit hard to debug when you specify all in your command.

Comment all lines in your hosts file add this line

[webserver]
35.165.79.66 ansible_user=ubuntu 

and try to run :

$: ansible webserver -m ping -vvv

And show me the output.

I changed the image disk in virtual box so the ssh key has been regenerated but from this moment I have an error message.

Could you help me ?

Generate the ssh key on the master node:

root@master:~# ssh-keygen -t rsa -C "[email protected]"

Then copy your public key to the servers with ssh-copy-id:

root@master:~# ssh-copy-id [email protected]
root@master:~# ssh-copy-id [email protected]

I got this informations on this website https://valdhaus.co/writings/ansible-post-install/ and it is working

@guruprasad85 it looks like you miss "python" on the remote machine (35.165.79.66).

Hi,
I have found the solution.
If you are using ami(ubuntu 16) OS then there is no python installed, so you need to install it. Use below command to install python -

sudo apt-get install python-minimal -y

or

you need to use ami(ubuntu 14)OS. It has python 2.7.

Note : confirm which version of OS you have in your system.

Glad you found the solution.

I'm trying to ping from an Ansible control machine (installed in a UBUNTU 14.04 VM), to a cent OS instance.
Both are google cloud instance (with python installed).
I'm unsure about the connection status between them. From the below results of ansible all -m ping I could see there is something wrong with my SSH.

Could you suggest me to achieve the connection between my VMs.

I am having the same problem @ganfotry . What is the cause of this issue ? Please direct me the right way.

I fixed it by generating keys in both the VMs and then copying the keys
viceversa inside authorized_keys.
I got the below response then:)

ansible -m ping all
127.0.0.1 | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
35.186.***.*** | SUCCESS => {
    "changed": false,
    "ping": "pong"

I was getting the same problem:

$ ansible local -m ping
127.0.0.1 | UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh: Permission denied (publickey,password).\r\n",
"unreachable": true
}

Solved the issue by installing sshpass using command:

sudo apt-get install sshpass

After installng sshpass, I executed this command:
`json ansible local -m ping --ask-pass SSH password: 127.0.0.1 | SUCCESS => { "changed": false, "ping": "pong" }
Hope this helps!!!

this worked for me, so may help you as well.
Try registering the private key to your keychain

ssh-agent bash
ssh-add <path to private key>

if this works, try adding the keys to your ~/.ssh/config file

Hi,
I am getting the below error while run the command in ansible tower GUI mode.

But I'm able to get the result in CLI mode on the server.

Thanks

Manually try to access the server on terminal, if you are able to ssh the remote server, then remove .ansible directory from local user's home directory. This works for me. (y)

Same for me!
I can ssh server via terminal without passing -i directive:

ssh [email protected]

works

Executing the command:

ansible all -m ping

I get the error:

    "msg": "Failed to connect to the host via ssh: Permission denied (publickey).\r\n",  
    "unreachable": true

@lkjangir removing .ansible directory didn't work also. =(

Try this, replace ec2-user with whatever username you set up.

ansible all -u ec2-user -m ping -vvv

@aelkz : in the /etc/ansible/hosts file, you could put: [email protected] instead of server.com and then try ansible all -m ping.
Otherwise, if you don't specified the user1 in /etc/ansible/hosts, you should specified the user in ansible command: ansible all -m ping -u user1
I had the same error and that solution solved my issue.

If i am not wrong , this is due to ssh key issue. Rene rate for new key or else convert your key to openssh formate to avoid error.

Using --ask-pass along with -u parameters worked for me.

@Hai-minhD Your solution worked for me, thanks. I was testing on hosts where I had the root user as the same user I was using in the control machine. In this specific host where I was getting the failure reported above, I have a different user. Solved adding the host with this username in it in the Ansible hosts file: username@host.

try-

ansible webserver -m ping --ask-pass -i path_to_local_hosts_file

Installed python on slave and it worked for me.

I have the same issue.
I find solution : I add /etc/ansible/hosts:
ansible_ssh_user= ansible_ssh_pass=.

Hope this helps.

root@ip-172-31-31-140:~/.ssh#

I had the same issue, ansible tries to connect using your current user name, so my way around it was overwriting the username, for example:
ansible all -m ping -u ec2-user

I faced two errors while running 'ansible all -m ping' and stumbled on this thread to t-shoot. I want to thank everyone for their inputs as it helped me figure this out.

:ERROR-1:
Steps to fix this message: "msg": "Failed to connect to the host via ssh: Permission denied (publickey,password).\r\n"
1)I modified fix configuration file at /etc/ansible/hosts to include the proper username 'ubuntu'
2)I passed the argument of '--private-key=/Users/my-user/.ssh/my-key.pem' so the command looked like this:
ansible all -m ping --private-key=/Users/my-user/.ssh/my-key.pem
This guide informed me on how to pass the key as an argument:
https://ansible-tips-and-tricks.readthedocs.io/en/latest/ansible/commands/

:ERROR 2:
"module_stdout": "/bin/sh: 1: /usr/bin/python: not found\r\n",
To fix I ran 'sudo apt-get update; sudo apt-get install python' on the remote host. I'm using an ec2 instance. Side note, running the install commands as part of the startup script would help resolve the second issue.

Cheers!

Looks like python was missing on our Ubuntu 16.04 servers. I installed it on all remote hosts and it fixed the issue:
sudo apt-get install python-minimal -y

SSH will connect with terminals but not with vsts and ansible, can any one help me

When I hit this I was using Ansible on OSX to connect to an aws box with a pem certificate. I did NOT have a ~/.ssh/config file. Once I created one and added no more than this:

Host *
IdentityFile ~/.ssh/id_rsa
AddKeysToAgent yes

Then I was magically able to execute playbooks.

i am getting the below error while trying to copy a file from control machine to a node.

COMMAND: sudo ansible dbservers -m copy -a "src=/etc/ansible/Taha dest=/etc/Taha"
Error:
52.186.71.70 | UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password,keyboard-interactive).\r\n",
"unreachable": true
}

I tried all the above listed steps, still no success....

try with passing inventory file and ssh key with a username. I don't have any user defined in inventory for nodes, so I pass with command and it always works for me. so the command will be like this -

sudo ansible dbservers -m -i inventory/inventory-file --user=ubuntu --private-key="private-key.pem" copy -a "src=/etc/ansible/Taha dest=/etc/Taha"

Thanks Lokesh for the help ...

As i am new to ansible, i just want to know where do i can save pem file on control server ? do i need to make changes in inventory-file ?

t Hi guys,
I had the same problem.
My devops user could ssh to all the servers but when I tried to runs, (with mysuer), ansible commands I always got the error ... UNREACHABLE! ...
I solved it by making , with "mysuer" ssh serverDestiny (the server that is in inventory file) note if you use fqdn you must make ssh to the FQDN.
example:
cat inventory
server1

[myuser@workstation ansible-deploy-cr] ssh-keygen
[myuser@workstation ansible-deploy-cr] ssh-copy-id -i devops@server1
test..
[myuser@workstation ansible-deploy-cr] ssh 'devops@server1

Hope this will help you.
if so, give a like 👍

Kindly help me out on this issue.. i guess we need to create ssh key's how to create step by steps process please i'm not expert

Kindly help

This is fixed by Adding the generate the ssh key to server and copying the same to client

Commands :

$ ssh-keygen -t rsa

hit enter

$ cd root/
$ la -la

copy id_rsa.pub to destination vm
$ssh-copy-id destination vm

ssh-copy-id -i user@localhost
ssh-copy-id -i user@servers_in_inventory

seems to work

This URL is the #1 Google hit for this error, so, although while this "issue" is closed, people will continue hitting this for the forseeable future. Here's how I fixed it for python3, ansible 2.5 (both are PIP versions, in a virutualenv), and OSX High Sierra.
Reporting my 'fix', for my scenario. Running:
$ python3 $(which ansible) localhost -m ping -vvvv

Would result in this error. -vvvv reveals it's a key/auth failure. Great. You can isolate Ansible from this by simply doing [email protected] and for me it failed (I'm considering a failure to login with SSH keys to be a failure).

Easy fix: at ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

I had the same problem and i get the solution by myself, i'm gonna tell you what's happening to me.
I get the same error and i solve it cz in the same proyect folder i had a hosts file, and for some reason, there was error so just with a rm -r hosts, i got solve it.
I expose to you if u have the same problem that i got.

Happy Christmas X) ,xoxo.

I had the same issue until I edited my inventory file with
[testserver]
<target_ip> ansible_user=<target_domain_name> ansible_ssh_pass=<target_pass>
Then to test:
ansible testserver -m ping

ubuntu@ip-172-31-1-85:/etc/ansible$ sudo ansible-playbook tomserver.yml

Are you trying to simply connect? What does your hosts file look like?

I have found the solution.
My operating system was Mac OS , and I change the 'ansible.cfg' in the line 'remote_user = root ' , the problem is solved.

Yup! I've had to do the same thing! Glad you solved it!

I ran the playbook with the following flags:

ansible-playbook playbook.yml --ask-pass - this helped.

In the hosts you could also do ansibleuser="user" ansiblepass="pass" right
next to the ip for the target. This allows me to run play books without any
extra password prompts.

try This

all servers - Works when both server's and client's user name are same (Passwordless)

ansible all -m ping

all servers - "raj" is managed node's user (Passwordless)

ansible all -u raj -m ping

OR

Only demo-servers group - "raj" is managed node's user (Passwordless)

ansible demo-servers -u raj -m ping

OR

If you use password authendication

ansible -m ping all -u raj --ask-pass

or you can follow this link for further information

What worked for me was to update my hosts file to have the path to the ssh key:

[webserver]
IP_ADDRESS ansible_user=ubuntu ansible_connection=ssh ansible_private_key_file=~/.ssh/key.pem

Nice solution. This would take care of multiple targets!

Two solutions we have : -

password less auth (you can refer google how to generate rsa key )
add ask_pass=true in ancible.cfg file. (This will ask password when you run ansible)

Please setup the SSH connection to the host machine and test it.
Once it's done, In the /etc/ansible/hosts file give the proper host IP.
Now to test the secure connection between ansible and guest machine use the below command:
-> ansible -i hosts -u vagrant --ask-pass -m ping all
hosts-> hosts file (give proper guest ip)
-u vagrant -> vagrant is my guest machine username
--ask-pass-> It allows you to enter the SSH password to connect to guest m/c.
Note: If i donot use --ask-pass it'll throw error.

Thank you if it helps :)

it is quite possible that your /etc/ansible/hosts is wrong

i am new to ansible, can anyone help me

Try to include the password for your target machine within your hosts file.
Typically, you will need to have had an existing ssh connection which
generates an RSA key for your host and your local machine. Try ssh into the
host then run ansible again.

When I use the ssh command from my local terminal I am able to connect to the ec2 instance. However when I run the ansible script I get the error.

With AWS ec2 instances, you must generate a public key through AWS,
download it, and point the ssh session to that key. There are tutorials for
this procedure online.

t Hi guys,
I had the same problem.
My devops user could ssh to all the servers but when I tried to runs, (with mysuer), ansible commands I always got the error ... UNREACHABLE! ...
I solved it by making , with "mysuer" ssh serverDestiny (the server that is in inventory file) note if you use fqdn you must make ssh to the FQDN.
example:
cat inventory
server1

[myuser@workstation ansible-deploy-cr] ssh-keygen
[myuser@workstation ansible-deploy-cr] ssh-copy-id -i devops@server1
test..
[myuser@workstation ansible-deploy-cr] ssh 'devops@server1

Hope this will help you.
if so, give a like 👍
Thanks,
MBrito

This fixed my issue in AWS on private VPC, I need the internal fqdn for all the servers

Hey guys,
I was facing the same issue for localhost and realised that '$ ssh localhost' was asking for a password. I solved it by moving the public key of 'user' on localhost to the authorized_key.

ssh-copy-id -i ~/.ssh/id_rsa.pub test@localhost

Just check if the authorized_key files have the necessary keys

test is the username

Wow.....I read through comments. Can not believe the issues still exist. I am on latest ansible. I guess this is one of the pain of using opensource.

SOLUTION

Alright, here is what worked for me -
I logged into the remote machine lb. edited the ~/.ssh/authorised_keys and added id_rsa.pub key of ansible master. Saved and exited. Bounced the sshd on lb.

This is not a perfect way, but it gets you going for initial testing.

Edit 1 - Also, you need to make sure the remote machine (client which will be managed by ansible) needs to have python installed.

PS - even the method of ssh-copy-id -i was failing for me with same error of permission denied (publickey)
