[MPICH2-dev] Why cannot i run "mpdboot" correctly

[yh sun]

hi everyone,
    I have installed Mpich2 by running commands "./configure; make ; make
install"
    According to the install guide.pdf , i am doing the next step to
configure it.
    I am trying the step "Start the daemons on (some of) the hosts in the
file mpd.hosts".
    When I run the command
                                   "mpdboot -n 9 -f mpd.hosts"
    The result shows that
                         "mpdboot_chemical.sccas.cn (handle_mpd_output 385):
failed to handshake with mpd on node-0-2.local; recvd output="

   My cluster has 9 nodes-- 1 fronted node, 8 computing nodes from node-0-1
to node-0-8.
   And my "mpd.hosts" file is like this
        node-0-1.local
        node-0-2.local
        node-0-3.local
        node-0-4.local
        node-0-5.local
        node-0-6.local
        node-0-7.local
        node-0-8.local
  And I am sure that I can ssh all the computing nodes from fronted node
without entering password.

   so what is the problem with command "mpdboot"?
   Thanks
   Regards
