Unhappy message passer interference problem in rsh


hello all,

i have installed mpi(mpi1.2.7p1) software on my centos5.2 computer, where right now i have connected two computer one is master and other is node (i have 10 computer will connect those when two computer works properly). the problem is with mpirun command.
when i type mpirun a.out it work fine but, when i type
mpirun -np 2 a.out this will show an following error ,
--------------------------------------------------------------------------
mpirun -np 2 a.out
connect to address 190.160.10.11 port 544: No route to host
Trying krb4 rsh...
connect to address 190.160.10.11 port 544: No route to host
trying normal rsh (/usr/bin/rsh)
node1: No route to host
p0_26380: p4_error: Child process exited while making connection to remote process on node1: 0
p0_26380: (3.000073) net_send: could not write to fd=4, errno = 32
--------------------------------------------------------------------------
i know this error is showing because of rsh is not set properly, but i have set passwordless ssh and its works fine now. now i want to know how to use ssh instead of rsh in mpi and make mpi command works fine . ...

any kind of help is appreciated ........
thank u
