Question regarding ssh login message

[Michael Hopkins]

Hi all

When I login using ssh to a FreeBSD box (Athlon) running amd64 5.3 from an
OS X laptop on the local network, I always get this message:

reverse mapping checking getaddrinfo for athlon failed - POSSIBLE BREAKIN
ATTEMPT!

...but then everything works fine afterwards.

People have suggested a mis-configured named setup, so now that is switched
off and all hostnames are stored in /etc/hosts.  The local network is small
(3 machines) and all external access is via the combined network router/ADSL
modem which links everything together.  The IP for this router is the only
entry in /etc/resolv.conf at each end.

I'm not sure if the ssh setup at one or both ends is to blame or if it's
somewhere in the network setup.  Does anyone have any suggestions on where
to look for the problem or diagnostic tools/logs that will help point to the
solution?  

TIA

Michael
