Hi there. You need to make sure portmap is running on the machine(s) (ps 
-ax| grep portmap). Then you may need to edit the /etc/hosts.allow file 
on the servers to allow portmap connections. It should contain these 
lines to only allow connections from 192.168.0.0 networks:

portmap : 192.168.0.0/255.255.0.0 : allow
portmap : ALL : deny


If security is a concern, you may want to look at using SSH instead.
