I'm fairly thick about this stuff here - I'm not sure where to look to  
see if sshd is doing dns lookups.

Even if it were, all 3 machines in question (mine, 2 servers) are on  
the same private lan (192.168.0.x).  How would dns come into play here?

/etc/ssh/sshd_config is identical for both machines.
