local ssh neighbors ?

A little bash function leveraging nmap .. mostly naive and fragile.
Until I learn how to do tcp|ip discovery.

neigh_ssh ()
{ 
    sudo nmap -v -p 22 --open --host-timeout 1 192.168.1.0/25 \
  | grep --color=auto -E -o "open port 22.*[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}" \
  | grep --color=auto -E -o "[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}" \
  | sort \
  | uniq
}
