Install "screen".

Login, run "screen", and you land at bash.

Later you might be disconnected, or you type the right escape sequence 
to disconnect (by default it is ctrl-a then "d") and logout.

Login again, "screen -rx", and you will be back where you started.

There are a lot more features, but that is the minimum.
