my question is how to best manage two layers of "screen" sessions:
In my institute we have a compute cluster for numerical simulation. To login on that cluster one has to go via a load balancer who distributes the users to 4 control nodes (from where they then can start jobs on the actual cluster and do post-processing) because the login process is a little complex (3 passwords ad a user interaction) I would like to keep one session open, which I can also resume from home. This implies running screen on my workstation. On the other hand I would like to have multiple screens on the control node using only one ssh connection, so I have to run screen also on the node. But if I do that I can only control the first screen (by "crtl+a" and "space" for example). What would be the best solution to this using only one ssh connection? Thanks for your help!
