Please be advised that this question is way outside the scope of Online Study List, which is a study list with the primary focus on CCIE Routing and Switching studies.
While we welcome some discussion on how to use different tools in the study, this is not a general computing mailing list. Please, try to find help for these issues someplace else and keep the "noise" level on OSL minimal.
