Update netexp script #13
Description
Want to see as much info about the hosts as possible
after arp -a, we should loop through each line and call nmap if installed and add info we can gleam from this.
Example call and output
> sudo nmap -sn 192.168.0.13
Starting Nmap 7.91 ( https://nmap.org ) at 2021-11-10 18:59 PST
Nmap scan report for 192.168.0.13
Host is up (0.077s latency).
MAC Address: EC:8E:B5:81:5B:4D (Hewlett Packard)
Nmap done: 1 IP address (1 host up) scanned in 0.16 seconds
Notes:
- Needed to install nmap with MacPorts on OSX
