== 4.  Configure and Initialize ==

`omni` comes with a script, `readyToLogin` which finds the login information for nodes in your slice.

As of `omni` version 2.8, it has an `--ansible-inventory` flag which generates the Ansible inventory, which is a flat file which tells ansible the name and login information for your nodes.

{{{
#!div style="background: #ffd; border: 3px ridge; width: 800px;"
On your local machine:

   {{{
#!python
readyToLogin MYSLICE --useSliceAggregates --ansible-inventory -o
cat inventory
ansible all  -m ping -i inventory
   }}}

Here is example output of running these commands:
   {{{
$ readyToLogin ansible --useSliceAggregates --ansible-inventory -o
Host info saved in inventory file: /Users/jdoe/projects/GENI/hellogeni/inventory

$ cat inventory
client  ansible_ssh_host=pc3.instageni.clemson.edu  ansible_ssh_port=33850
server  ansible_ssh_host=pcvm3-6.instageni.clemson.edu

$ ansible all  -m ping -i inventory
client | success >> {
    "changed": false,
    "ping": "pong"
}

server | success >> {
    "changed": false,
    "ping": "pong"
}
   }}}
