My solution would be to first do a ping scan on the hosts with --unprivileged, then do the real scan with -Pn and without --unprivileged
Anyway it's my problem now, thanks :)

For example you can take a totally randomly written IP : 192.125.125.0/24
from nmap.
Hi @mxrch ! Thanks for opening this issue :)
Just for clarification, the nmap package does not tell or do much, it just calls the nmap
binary. Do you encounter a different behavior when running the nmap
binary with the same parameters? Since the package simply parses the output of the binary to define what to return to its users, I am assuming that for some reason while it might not be visible with the standard nmap
output, if you enable the -X
(XML) option in Nmap to test it yourself, you'll see hosts shown as up.
Could you please provide more information, such as:
- the actual contents of what
nmap
returns to you - the XML output of the nmap command when you run it yourself (not through the package) -- to rule out a parsing issue
- if possible, the XML output that the nmap package creates when running nmap (you can do so by using the
WithNmapOutput
scanner option)
// WithNmapOutput makes nmap output standard output to the filename specified.
func WithNmapOutput(outputFileName string) Option {
return func(s *Scanner) {
s.args = append(s.args, "-oN")
s.args = append(s.args, outputFileName)
}
}
Thank you :) Have a good day!

Hello @Ullaakut, thanks for responding fast.
- Here is what nmap returns to me : https://pastebin.com/wvNHz3Fk
- The XML output of the nmap command : https://pastebin.com/eusJmfqW
- The XML of the nmap package : https://pastebin.com/F34ZBjdg
I have just noticed that this is caused by... launching nmap with sudo.
nmap 192.125.125.7 -p 80,443
Starting Nmap 7.80 ( https://nmap.org ) at 2021-03-24 15:13 CET
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 3.04 seconds
sudo nmap 192.125.125.7 -p 80,443
Starting Nmap 7.80 ( https://nmap.org ) at 2021-03-24 15:13 CET
Nmap scan report for 192.125.125.7
Host is up (0.00038s latency).
PORT STATE SERVICE
80/tcp filtered http
443/tcp filtered https
Nmap done: 1 IP address (1 host up) scanned in 1.40 seconds
from nmap.
No problem, thanks for the detailed explanations, this might help other people in the future! :)
