Someone raised a couple of good questions in a private email to me, so I
thought I'd go ahead and send my response to the whole list. I didn't know if
they'd want me to forward their response to the list, so I've omitted their
response, just to be safe. :) My apologies if you prefer attribution, feel free
to reply to this if that is the case.
First, I verified my trustkeysfrom and @(def.acl) settings were correct. As for
the second point, my remote_copy_with_backup body already has trust enabled.
body copy_from remote_copy_with_backup(filename, hostname) {
source => "$(filename)";
servers => { "$(hostname)" };
compare => "digest";
copy_backup => "true";
trustkey => "true";
}
As for my goal, I had shortened my original email to make it easier to
understand but the response made me realize that I took out an important point.
My goal is to have all systems trust lum so that they can retrieve the sudoers
file, though some systems don't need to fetch that sudoers file. However, I do
have an edit_line bundle (promiser is "$(root_homedir)/.ssh/authorized_keys")
that defines a variable by calling remotescalar(), which is a function specific
to Cfengine Nova and does not include a key exchange mechanism.
"remote_user_public_key" string => remotescalar(
"$(user)_public_ssh_key_access", "$(host)", "yes"
);
When $(host) is lum (which is the only way I'm calling this bundle right now),
it's not trusted by clients that don't retrieve sudoers and thus those systems
couldn't get lum's public ssh key. I had no other way of ensuring all systems
could successfully use the remotescalar call to get lum's public SSH key.
