nmap

[James Linder]

Hi All
still in pursuit of passwd-less logins to High Sierra.

Here fire is a VM on haycorn with bridged network (VirtualBox)
[fire] /home/jam [1798]% cat /etc/issue
Ubuntu 18.04.1 LTS \n \l
haycorn is my high sierra machine

[fire] /home/jam [1804]% nmap --help
Nmap 7.60 ( https://nmap.org )

[haycorn] /Users/jam [182]% nmap --help
Nmap 7.70 ( https://nmap.org )

[fire] /home/jam [1796]% nmap -sP 192.168.5.1-254 |grep -v Host

It seems the port of nmap is quite different to linux nmap.
What is happening
Thanks
