Hi all,

I’m trying to use ansible with hosts located inside a DMZ. All the remote hosts have PasswordAuthentication no, RSAAuthentication ye,s and PubkeyAuthentication yes. So, when I try to connect using my playbook I got: [http://pastebin.com/hg2HQNVc](http://pastebin.com/hg2HQNVc)

Also:

$cat ~/.ssh/config

ControlMaster auto  
ControlPath /tmp/ssh-mux-%h-%p-%r  
ControlPersist 4h  
ForwardAgent yes  
ServerAliveInterval 30  
ServerAliveCountMax 120

Host bastionhost  
HostName [example.com](http://example.com)  
User testuser  
Port 22  
IdentityFile /home/localuser/.ssh/id\_rsa

Host remotehost  
Hostname 192.168.1.20  
User testuser  
Port 22  
IdentityFile /home/localuser/.ssh/id\_rsa  
ProxyCommand ssh bastionhost -W %h:%p
