Why does 'ssh' and 'scp' work to one and not another?

[kitepilot at kitepilot.com]

OK, this is what we know:
>> joe:x:500:500:Joe:/home/joe:/bin/bash
You can log in with a valid shell. 

>> ssh -v localhost (on 73)
It doesn't say in your message that .73 accepted the password, but:
a.- If you could not complete the login because it refused the password, 
then you have a problem local to .73
b.- If you logged in successfully, then your problem is most likely outside 
the .73 machine, unless you are running xinetd (ps aux|grep inetd) 

Now I apologize, because:
>> ssh -v <73> -- and post that too
Actually meant:
>> ssh -v <place here the full IP address of .73> -- and post that too
:) 

I still don't know what the problem is.
But I know what it is not...   :)
If you grant me access to .73 I'll help you debug it over the phone, this 
could be a long array of issues, and maybe more than 1.
