[chef] Re: Re: Calling Chef::Knife::Ssh directly(?)

[Seth Chisamore < >]

It appears you have a conflict between the node_name associated with your 
client_key and the one you are setting with:

knife_ssh.config[:node_name]

The client key is most likely being picked up in the config file passed in 
with:

knife_ssh.config[:config_file]

You should make a choice to either set all values in the config file...or 
punt and set all values manually (ie node_name, client_key, chef_server_url 
etc.) in the knfe_ssh.config hash.
