arrangement to always assign the same name to the address they've assigned
to you (most don't -- they just have a unique name that's permanently
associated with each dialup address), there's nothing you can put in your
.rhosts file that will work well.
Before someone suggests something like dyndns.com, I've already thought of
that. The problem is that those services only implement forward DNS. The
r-command servers generally use reverse DNS -- they translate the client
address to a name and then check the .rhosts file to see if the name is in
there. Reverse DNS is controlled by the ISP, not the dynamic DNS provider.
