Installing GNU Screen on SecurityOnion

Running the command sudo soup on your manager node gives you this warning:

WARNING: If you run soup via an SSH session and that SSH session terminates, then any processes running in that session would terminate. You should avoid leaving soup unattended especially if the machine you are SSHing from is configured to sleep after a period of time. You might also consider using something like screen or tmux so that if your SSH session terminates, the processes will continue running on the server.


You can install GNU Screen on your manager node using the command sudo dnf install screen.

Here are three handy configuration files.
