I have conect the 4 computersin star topology
I installed freebsd in the master node
          standar installation

I installed Freebsd same in the others computers, but when ask it for

-----------------------------------------------------------------------------------------------------------
ssh-rsa   ........keyletters.....................   == root at nodo1
----------------------------------------------------------------------------------------------------------------------

I configured the ssh with root
#ssh-keygen -t rsa
enter
enter
enter
enter

copy the content of the file "id_rsa.pub" of node to file
"authorized_keys" in masternode and copy the same again inthe
masternode and nodes

now I can login only write in the masternode
#ssh nodo3
and I cant see all the files in thecomputer nodo3, and in the computer
nodo3 i write
#ssh nodo1
and i can see the nodo1 to do all things

the same with rsh nodo1 and rsh nodo2,3,4,
----------------------------------------------------------------------------------------------------
later I installed the mpich, with root

#./configure --prefix=/usr/local/mpich-1.2.7
#gmake

I modified the file /usr/local/mpich-1.2.7/share/machine.freebsd
----------------------------------------------------------------------------------------------------------------
nodo1.cluster.dominio.com
nodo2.cluster.dominio.com
nodo3.cluster.dominio.com
nodo4.cluster.dominio.com
----------------------------------------------------------------------------------------------------------------

and is all the files, that I modified, later I tried the tstmachinces
-v and I have the problems to conect with the nodes,


please, Help me,...


and thanks for the help to all people
