[Condor-users] Problem with sshd.sh, ssh-keygen and Parallel Universe

[Pierpaolo Minelli <pierpaolo.minelli@xxxxxxxxxxxxxx>]

Hi,

i have a problem using mpi wrapper script on my cluster (CentOS 5.3).  
Sorry for my english.
This is my cmd file:

universe = parallel
executable = mp2script
arguments = a.out
machine_count = 2
log = mpi.log.$(Process)
output = mpi.out.$(NODE).$(Process)
error = mpi.err.$(NODE).$(Process)
notification = error
should_transfer_files = yes
when_to_transfer_output = on_exit
transfer_input_files = a.out, mpd.hosts
queue

When I submit this cmd, I obtain this error file (after inserting 'set  
-x' in mp2script):

++ trap sshd_cleanup 15

hostkey -t rsa -N ''
++ '[' 1 -ne 0 ']'
++ echo ssh keygenerator /usr/bin/ssh-keygen returned error 0 exiting
++ exit -1

ssh-keygen seems not to works properly but i don't know why....

Someone can help me to solve this problem?
