I am remotely connected to a system using ssh and want to run nmap on a system from there. But every 5 minutes, my SSH connection breaks and so the process running on my shell stops.

How can I run nmap in the background so that any SSH session can interact with the process?

You could use nohup. But screen is what you are probably looking for.

The task you are describing can unfortunately not accomplished by simply sending the process in the background on the remote machine. Even if you started it with

user@remote~$ ./script &

it would get killed if your SSH connection breaks.

Instead, you will have to use a terminal multiplexing software such as tmux or screen (availability may depend on your specific OS).
