Subject: [OMPI users] Ssh problem

Dear OpenMPI developers,
i'm trying to use OpenMPI 1.3 over my laptop but i have a problem with
ssh. When i launch an MPI program with mpirun, i retrieve the follow
error:

ssh: connect to host .... port 22: Connection refused.

A daemon (pid 7008) died unexpectedly with status 255 while attempting
to launch so we are aborting.

This may be because the daemon was unable to find all the needed
shared libraries on the remote node. You may set your LD_LIBRARY_PATH
to have the location of the shared libraries on the remote nodes and
this will automatically be forwarded to the remote nodes.

I have setted LD_LIBRARY_PATH, but still doesn't work.

Could you help me? Thanks in advance.
