</div>

the syntax for ssh-copy-id is: ssh-copy-id -i ~/.ssh/mykey user@host

And i want: from Host1 to Host2  
and from host2 to host1

I don’t know how to specify the other host in a such a scenario

Do one host first then the other if you are doing this manually. If you are trying to use ansible to exactly do this steps then use the user module and authorized\_key

I found a solution:

In my inventory files i put the remote IP and the remote ssh key.  
In my task main.yml i use:

- name: copy the ssh key  
authorized\_key:  
user: root  
state: present  
key: “{{ remote\_key }}”

that solve my problem.

Thanx for the help
