1. problem statement
I have to create function in which read IP addresses one by one from one file (iplist.txt) and scan these IP using nmap. This scan IP's output is saved in output.txt file and parse output.txt to save only open ports with particular IP in parse.txt file.
format of parse.txt file:
Code:
Code:
ip port
x.x.x.x x
2. My goal:
1. Find all ports open on a whole range.
2. Save only open ports with IP address in another file. Don't save filtered or closed ports in this file.
eg. Format of file:
IP_address Open_port
Code:
192.168.0.1 21
192.168.0.1 80
....
so I have write the script which scan IP range. I just want script of second option.
I have attached the script. Please help me if possible to implement second option. In second option, my script take open port/tcp and all other details but i want only ip address with open port.

I'm seeing a persistent address showing up on my firewall router logs. The address is 10.98.115.9:67, and is broadcasting to 255.255.255.255.

mdns-scan
MDNS-SCAN(1) General Commands Manual MDNS-SCAN(1)NAME
mdns-scan - Scan for mDNS/DNS-SD services published on the local network
SYNOPSIS
mdns-scan
DESCRIPTION
mdns-scan is a tool for scanning for mDNS/DNS-SD published services on the local network. It issues a mDNS PTR query to the special RR
_services._dns-sd._udp.local for retrieving a list of all currently registered services on the local link.
OPTIONS
mdns-scan has no commandline options.
NOTES
mdns-scan is not a good mDNS citizen since it queries continuously for services and doesn't implement features like Duplicate Suppression.
It is intended for usage as a debugging tool only.
mdns-scan is incomplete since it doesn't resolve mDNS services for you - it just dumps their PTR RRs. To understand these records you need
minimal knowledge of DNS-SD and how it works.
mdns-scan does not terminate on its own behalf. It scans for services continuously until the user kills it by pressing C-c.
mdns-scan does not rely on a local mDNS responder daemon. It has no dependencies besides the GNU libc. It has been tested on Linux only.
mdns-scan does NOT scan for local mDNS enabled hosts or A/AAAA RRs, it scans for DNS-SD registered services, nothing else.
