MPI-LAM on a Linux beowulf cluster

[Yann COSTES]

Hi Beowulf people,

I am installing MPI-LAM on a Linux beowulf cluster built in diskless.
On this cluster, every client node has a /etc/nologin file in order to
disable users to connect on.
Unfortunately, with this file it's impossible to use rsh or ssh towards
a client node.

Does anyone know a solution permitting to use LAM without users may be
able to connect on a client node ?

Thanks in advance for your help.
