You don;t have to change anything to the scripts. What BBB sends to SL is a tar file with the whole recording.

What I have found as a common error is that BBB is not able to ssh into SL.

If you do follow the steps it should auto-magically work, if you don;t, you have to make sure to replicate manually wat is done by the automated scripts. Which you did, I know, but in this case you have to double check every single step.

Tuning up these scripts and getting them to work took me a while to be honest. One little detail such as permissions or using the wrong name for the directories, or location and the whole thing is screwed.
