[MPICH] passwordless rsh/ssh

[Syed Irfan]

Hi Kevin,

Well you need to add the user who is going to rsh under $HOME/.rhosts 
(refer 2)

if you want to use hostname instead of ip address add the appropriate 
hostnames and ip address to /etc/hosts (refer 2)

1. for passwordless ssh look here:
http://www.massey.ac.nz/~jriden/passwordless-ssh.html

2. for passwordless rsh login look here:
http://users.tpg.com.au/devdsp/2.rsh_config.html

As always a lot of info provided in the mpich2 user manual. Thanks to 
the authors of the manual very helpful :)
