Phooey!  I was wrong.

>From compt1
$ ssh compt2
ssh: compt2: Name or service not known

$ ssh <compt2's IP>
The authenticity of host '<compt2's IP> (1<compt2's IP>)' can't be
established. ... Which, of course is just fine.

Any ideas about what I'm doing wrong and/or not doing (right)?  Surely
it is possible to to do ssh compt1 from compt2 and be logged on to
compt1.  In fact, I do it at my ISP.  Now if I could only figure out
_how_ they do it, I would be moderately happy. :)
