Hi! I am looking for host up/down type of scanning (like ping sweeping). I just don't know if I shall run single nmap or 4-16 of them in parallel... -- BR, Bart Dnia 17 marca 2010 14:27 Ron <ron () skullsecurity net> napisaĆ(a):
Depending on how thorough you want to be, and how your network is set up, you might be able to save a lot of time and packets by first determining which subnets (/24 or /16) are active by scanning a handful of addresses in each, then only scanning those. That's what I do at work, but our network here is kinda lame (in terms of speed).

Would it make sense to run couple of nmaps in parallel? nmap ref. guide mentions that there is a mechanism for adjusting the speed of scanning based on network performance, thus the question if I should run single nmap -n -T Insane 10.0.0.0/8 (it's fast network here) and it will use up the resources or shall I split the scope onto 8 (16?) subscopes? Any additional parameters that could speed things up (without compromising reliability too much)? I have found that nmap's ARP ping scan alone is not good here. Any tip appreciated :) -- Best regards, Bart _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://seclists.org/nmap-dev/-- Ron Bowes http://www.skullsecurity.org http://www.twitter.com/iagox86 _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://seclists.org/nmap-dev/
