Maybe slightly off-topic, but does anybody here know how to record an(or any) SSH session(s)? On a debian server, for example?

I remember seeing someone do a demo on this but the result, after only 2 minutes where insane. There was so much data to go through that you might aswell just give up on trying to get anything useful.

In the old days I played with something like this: https://github.com/desaster/kippo

But a more modern alternative seems to be the container based approach outlined here. https://lwn.net/Articles/848291/
