Package:nmap
Version:4.53-1~bpo40+1
When I execute /usr/bin/nmap --open -n -p 515,631,9100 192.168.7.0/24
<http://192.168.4.0/24> 2>/dev/null | grep ^Interesting | awk '{print
$4}' |cut -d: -f1,
It doesn't show some printers that exists on the net. Example:
ServerName:~# /usr/bin/nmap --open -n -p 515,631,9100 192.168.7.0/24
2>/dev/null | grep ^Interesting | awk '{print $4}' |cut -d: -f1
ServerName:~#
We can see that exists a printer with ip 192.168.7.221:
ServerName:~# /usr/bin/nmap --open -n -p 515,631,9100 192.168.7.221
2>/dev/null | grep ^Interesting | awk '{print $4}' |cut -d: -f1

If I install namp 4.11 version, i always find the printer with the command:
ServerName:~# /usr/bin/nmap -n -p 515,9100 192.168.7.0/24 | grep -B3
open | grep Interesting | cut -d" " -f4 | cut -d: -f1

ServerName:~# dpkg -l|grep nmap
ii nmap 4.11-1
The Network Mapper
Same problem we can find on 4.62 and 4.68 versions. The bug happens in
a random way, ocassionally it works!

this a bug?, or anew funcion of nmap?
