Question reverse mapping checking getaddrinfo failed when ssh to newly named host


I receive an error:

Next authentication method: gssapi-with-mic
reverse mapping checking getaddrinfo for [ipofserver].slicehost.net [ipofserver] failed - POSSIBLE BREAK-IN ATTEMPT!

when sshing to a new server I setup. I just created a DNS entry to it and when I ssh to it using the DNS domain it takes a while for the ssh to succeed and I get that error.

Any help in resolving this issue would be appreciated.

It sounds as though SSH is trying to validate your hostname/IP pairing with public DNS records, not your local ones. I recommend that you use a different validation scheme, or learn a lot about DNS so SSH isn't confused about where to look for validation.
