I'm trying to run MPI programs on 8 machines, but I get the error

connect to address 127.0.0.1 port 544: Connection refused
Trying krb4 rsh...
connect to address 127.0.0.1 port 544: Connection refused
trying normal rsh (/usr/bin/rsh)
lagrid02: Connection refused

When I run it with a machinefile option, I get the error lagrid03: No route to host where lagrid03 is the neighbouring node connected to master node.

How should I rectify this ?

connect to address 127.0.0.1 port 544: Connection refused

Are you running RSH? (Why aren't you using MPI with SSH?)

No route to host where lagrid03

Do you have a route to it? Can you ping lagrid03 and get replies?
