We block all shell access for all our products. In the past, years ago this caused a huge issue with supporting mistakes when users accessing the shell (typo errors....). So in place we provide the Demo-CD's for a 30 day eval. for all customers to view all the features and options with our products, this provided customers information before implementing our products.
If you need a symlink for DSS, please send in your request to support@open-e.com asking if the software engineers can provide you an update.
