Answer 1

You have a tmux session running, where the root user is logged in.

To view your tmux sessions, run:

tmux ls

This will give you a list with one or more open sessions, like this:

$ tmux ls
session-name: 6 windows (created Tue Mar 12 08:47:53 2024)

To destroy the session(s), run this:

tmux kill-session -t session-name

This will kill the session and remove all associated users that are logged in to the session.

Another option is to attach to your tmux session and log out all users manually - but judging from your question, it seems you want to shut down the session entirely.
