Your problem might be that the host you are logging on to does not know
who or what your machine is.  Check what your machine sees by the 
following.  Remote shell into the target machine and type in the following:

% whoami
   tim
% who | grep tim | awk '{print $6}'

	(myname.sub.domain.)   or (1.2.3.4)

More than likely your entry in .rhosts does not match the return
from who.  If it gives a name, place it in .rhosts.  I suspect it
only knows the address.

If your target machine is a host table driven beast, put an entry into
/etc/hosts corresponding to your machine.  If it is a domain nameserver
driven sort, the deal becomes a little more difficult (but not much).
Ask your local network guru to 	enter a record into the zone tables 
corresponding to your machine.  Typically, the zone tables are listed
as hosts and hosts.rev in the directory [/usr]/etc/named.

In /usr/etc/named/hosts:

myname.sub.domain.	IN	A	1.2.3.4
				 ^				<<-  don't forget the trailing dot.

In /usr/etc/named/hosts.rev:

4.3.2.1.in-addr.arpa.	IN	PTR	myname.sub.domain.


	I hope this helps.  I would be interested personally to see what the
	problem is.  I am considering looking into PC-NFS or equivalent.
