      Description

      The backend code uses the nmap utility to determine if a remote node is responding to SSH. This may take several seconds if DNS isn't configured. There is a "-n" switch which causes the commands to run much quicker.

      The switch should probably be added. We need to test how it works with both hostnames and IP addresses.
