Ansible 1.9.1 SSH Error from ping module to Junos

Good afternoon all, my apologies for posting but I have been stopped at this point with no result for a few days. I have installed Ansible 1.9.1 and , I believe, all required dependencies on CentOS 7 , I am looking to use Ansible to manage Junos equpment and installed the Juniper.junos module along with its dependencies.

When I try to connect to my hosts via ansible ping module I am having an SSH issue. From my Ansible server I can directly SSH to the Junos devices that I want to manage using the public rsa key loaded into my Junos config for login “matt”. But when I run the ping module I am unable to complete the test. Here is my output…

[root@localhost /]# ansible all -m ping -vvvv

}

I also tried ping as root to the Junos devices using the -u and -k options, again I can connect directly via SSH, but when I run “ping” or a playbook referencing “ping” then enter the password I also cannot connect.

Can someone help?

So, after continuing to look at this it appears that SSH / paramiko are working but the ping module is failing to load the python interpreter. There are symbolic links already created from /usr/bin/python —> /usr/bin/python2.7 … I tried specifying the direct path to the hosts file

10.71.16.2 ansible_python_interpreter=usr/bin/python2.7

This produced the following error (at least referencing the new location for python interpreter)

10.71.16.2 | FAILED >> {
“failed”: true,
“msg”: “/usr/bin/python2.7: not found\n”,
“parsed”: false
}

Any help would be greatly appreciated.

the ping module uses the python on the target machine (it is not a
network ping), do the junos switches have python on them?

Hi Matt,

in the /etc/ansible/hosts
host1 ansible_connection=local ansible_ssh_host=10.71.16.5

hope this may help you

This got it for me!
Ansible threw out so many weird errors, once local connection was specified… they all went away.
