Hi guys, I am having problems with nmap on osx.  I use nmap on kali almost
daily, and it works fine, but every time I run a scan from the osx side, I
receive results showing all hosts are up and the same exact ports open on
every box.  I emptied the arp cache, turned off the firewall, stopped av,
and I still get these results.  Also, if I NAT kali, I get these erroneous
results, but if I bridge it, everything works fine.  Here is an example of
the output:

There are only 3 boxes on this subnet, and none of them are running these
services.
