Restricting RMI calls by host

[Mark McKay]

I'm designing an RMI server, and I have some procedures that I only want
to verify are only called by machines running on certain host machines
(ie, I have some servers that will connect to other servers and I want
to verify that it's my servers that are doing the connecting and not a
malicious spoofer somewhere on the net).

Is there a way for an RMI server to dectect the host ip/address of the
caller of a method?
