tmux is a terminal manager that allows you to disconnect from the server without losing processes and history and then connect to the same window (similar to screen).
Installation on Ubuntu / Debian:
sudo apt-get install tmux
An example of joining an existing running tmux manager:
tmux attach
An example of creating a new manager:
tmux new
