Hi ,all
So now ,2 solution can work
1 : changed --unprivileged to --disable-arp-ping
2 : add the �CPn to the preview code
open(FPING, "nmap -PE --system-dns --unprivileged -Pn --send-ip -sP
$more_options " . join(' ', @$nodes) . " 2> /dev/null|") or die("Cannot open
nmap pipe: $!");
or
open(FPING, "nmap -PE --system-dns --disable-arp-ping --send-ip -sP
$more_options " . join(' ', @$nodes) . " 2> /dev/null|") or die("Cannot open
nmap pipe: $!");
But stop the firewalld is not work (rhels 7.4 )
[root@mgt ~]# systemctl status firewalld

Hi, Casandra
This case may cause by the switch ,and here are the temp solution from Jarrod
to update the pping code
had to change pping
open(FPING, "nmap -PE --system-dns --disable-arp-ping --send-ip -sP
$more_options " . join(' ', @$nodes) . " 2> /dev/null|") or die("Cannot open
nmap pipe: $!");
I changed --unprivileged to --disable-arp-ping
that seemed to work
[root@mgt ~]# nmap -PE --system-dns --unprivileged --send-ip -sP switch1
Warning: You are not root -- using TCP pingscan rather than ICMP
Starting Nmap 6.40 ( http://nmap.org ) at 2018-05-09 07:24 CST
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn
Nmap done: 1 IP address (0 hosts up) scanned in 2.00 seconds
[root@mgt ~]# nmap -PE --system-dns --unprivileged --send-ip -Pn -sP switch1
Starting Nmap 6.40 ( http://nmap.org ) at 2018-05-09 07:24 CST
Nmap scan report for switch1 (172.30.50.1)
Host is up.
Nmap done: 1 IP address (1 host up) scanned in 0.00 seconds
[root@mgt ~]#
it may be cause by this type of switch ("Arista Networks EOS version 4.20.1F
running on an Arista Networks DCS-7260CX3-64 “ )
