  • In this video, I demonstrate how to perform host discovery on a network with ping sweeps using Nmap. Nmap is a free and open-source network scanner created by Gordon Lyon. Nmap is used to discover hosts and services on a computer network by sending packets and analyzing the responses. Nmap provides a number of features for probing computer networks, including host discovery and service and operating system detection.

    For TCP:
    Open means a service is running (tcp syn ack received)
    Closed means nmap got a tcp reset message (default behavior as indicated by rfc-whocares)
    Filtered means the packet was dropped or responded with icmp port unreachable (non standard, indicates packet filtering or network issues)
    For UDP:
    Open means that the request got a response (uncommon, but you know something is running)
    Open | Filtered means that you got no response (since udp doesn't respond typically nmap can't determine if the packet was dropped or got through)
    Closed | Filtered means you got an icmp port unreachable (default response for non existing services, or perhaps firewall rule)

    Don't use `-sn` without `sudo` otherwise it will scan 80, 443 ports to detect the host and if there is a firewall on the other end host will not be detected, and that method is slower for host detection
    Tips to detect every host:
    1. use sudo with `nmap -sn ` (uses ARP scan, which is fast as well)
    2. use `nmap -sL | grep \)` (it will use rDNS lookup technique, so nmap don't send request to the host directly)
    OR
    use -Pn with -sn `nmap -Pn -sn | grep \)` (uses rDNS technique like -sL)
    use --packet-trace with every command to see the packets.

      For me only the ip address is shown not the host name. Example: Samsung-A32 all that stuff? How to resolve it?

    @HackerSploit - Question: How do you I perform a nmap sweep to identify live hosts in a network when all I have is an IPv6 address?

    • @diru424
      @diru424 4 года назад

      Nmap -6 [target ipv6 adress]
      This is the command you may use to perform a default ipv6 port scan.
      You can't scan multiple hosts in a single command as its pointless in this context.
      So if you have to scan a network of systems and you only have their ipv6 addresses you may do that by creating a list of all ipv6 addresses you have and scanning them using the following command.
      Nmap -6 -iL -sn list.txt
      I havent worked on ipv6 either but i hope this helps, please let us know if this solves your porblem..
      Peace

    hello please I need help, I am a beginner in using nmap. I don't know what the problem is, if I try to scan an IP, it sends a message that host seems down, if it is really up, but blocking our ping probes, try -Pn. please what should I do to solve this?

    So I guess I just have bad luck and I cannot get results with my home network. I have direct tv and their default router. But even if I use nmap on it. It won't tell me the manufacturer or any connected devices which blows when trying to learn tools by hacking my own equipment.
