Did you forget the domain name...

[Xenon]

I know this question has been asked countless times here, and I've
read through all the archives and sites that I could find related to
this error, but I'm still having a problem and am not able to find a
solution.

Presently just trying to get things working with 1 server and 1
client, I get the "Host authentication failed. Did you forget the
domain name or IP/DNS address registration (for ipv4 or ipv6)?" error,
from both the server and client.

I have a very simple setup currently, just trying to copy a single
file from the server to the client.

Here are the files, I've changed the IP's and hostname's to protect
the innocent and the guilty. Some of the configurations have been
taken from an existing CFEngine configuration working in another part
of the company. I am currently just trying to get the files to
transfer, after that I will work out securing everything, etc.
Running CFEngine version 2.1.5

I'm brand new to all of this and somewhat overwhelmed, any help that
you can provide is much appreciated.

The things that I've done so far, after searching around for this
error, I've found the possible solutions below and have checked and
tried them.

Possible: Forward and reverse DNS not working, use SkipVerify and/or
SkipIdentify to make CFEngine not care about DNS. (I tried both of
these, on both ends, get same error) (also verified and fixed the
forward and reverse DNS for the 2 systems, and now both can forward
and reverse DNS each other.)

Possible: User not allowed? (Though I did not get this specific error,
it seemed to be one of the causes of the error that I did get, so I
verified that the AllowUsers directive is being used)

Possible: Keys are not correct or not shared, etc (Verified the keys
have been generated and are in the proper directory, also from the
debug output of the command you can see that the key is accepted
before it gets the error)
