This fix addresses the following issue:

If the sshd daemon is configured to display a banner message to remote users, the unexpected output of the banner message might cause the use of ssh and scp within the LSF Data Manager to fail. This fix changes the use of ssh and scp so that the following options are used by default: "-q -n -o PasswordAuthentication=no -o BatchMode=yes"


These options are as follows:


-q 

Quiet mode. Supresses all warning and diagnostic messages.

-o PasswordAuthentication=no

Specifies that password authentication is not allowed.

-o BatchMode=yes

Specifies non-interactive mode (or batch mode). If password authentication is required, the command fails without prompting.


You can now control the use of ssh and scp in LSF Data Manager by specifying the following two new lsf.conf parameters:

- LSF_DATA_SSH_CMD defines the default SSH command. The default value is "ssh -q -n -o PasswordAuthentication=no -o BatchMode=yes".

- LSF_DATA_SCP_CMD defines the default SCP command. The default value is "scp -q -o PasswordAuthentication=no -o BatchMode=yes -r -p".

The LSF_DATA_SCP_CMD definition does not apply to the job transfer script. To change the use of scp in the job transfer script, you must use the FILE_TRANSFER_CMD parameter in the lsf.datamanager file.

If you change the value of the LSF_DATA_SSH_CMD or LSF_DATA_SCP_CMD parameter, you must restart the dmd daemon to apply the changes by running 'bdata admin reconfig'.


Note: It is recommended that LSF 10.1 Fix Pack 6 be applied to make available these new data manager enhancements:

When a job with a new data requirement is initially submitted, a transfer job is no longer immediately created. The transfer job will be created after LSF considers the job elligible for scheduling.


Configuring a queue as a transfer queue in LSF (setting DATA_TRANSFER = Y in lsb.queues) no longer requires enabling the LSF Data Manager (setting LSF_DATA_PORT and LSF_DATA_HOSTS in lsf.conf). This is to support LSF staging jobs (jobs submitted with -stage option). A transfer queue can be shared by jobs that have a staging requirement, and jobs that have a data requirement. Jobs cannot have both a staging requirement, and a data requirement.

There is now a new lsf.conf parameter LSF_DATA_CLUSTER. This is to be used when multiple clusters use the same dmd in a non-MC situation. The clusters where the dmd does not live set the parameter to the cluster name where the dmd lives. The DM bdata command will check lsf.conf for LSF_DATA_CLUSTER and use the configured value when invoking the eauth (unless a remote cluster is explicitly specified).
