Subject Re: Running ssh from as an olio tool.

Sorry for the delay. You need a Faban 1.0.1 feature that allows you to 
specify the managedHost field. This will be the systems being managed as 
opposed to the systems the load is driven to. Sometimes the latter can 
be a load balancer. Also a minor change in the submission form is needed 
to show this field.
