I'm looking to scan a network with multiple subnets. I'm looking for a way to shorten this to one command rather than entering each subnet. So let's say I'm try to scan 192.168.1.xx, 192.168.2.xx and so on until 192.168.10.xx. with a specified port. Is there a better way to do this or can I only scan one at a time?
Yes, provided the devices are reachable on the network they can be scanned. The accuracy of the results (e.g. fingerprinting) is dependant on the platform, software version, running services and configuration. Example: $ nmap -A -T4 10.1.1.1. Nmap scan report for 10.1.1.1. Host is up (0.020s latency).
You see, nmap has several "phases" during a scan. In the first phase, called Host Discovery, all targets are pinged, to see if they are online. During the second phase, the actual port scan is performed. The commands -sL, -sn and -Pn modify this behavior. -sL only lists the targets to be scanned, skipping both the host discovery and the port ...
With nmap, you do scan for services at the IP layer (3) of the ISO/OSI model. Mac addresses are layer 2. This would not keep you from resolving mac addresses to IP addresses using . arp -na and working your way from there, though.
When nmap runs as a non-root user, it performs a TCP scan by default. TCPwrapper is software at host machine which closes the TCP connection after three way handshake when the client has no access to a particular port. So run nmap as a root user which uses SYN stealth scan for port scanning.

15. Using nmap: sudo nmap -O <target>. Or if they block your ping probes you can do: sudo nmap -O <target> -Pn. Sometimes you still get fake results and you should try doing an aggressive scan (can be detected and blocked by the firewall). sudo nmap -A <target>. Share. Improve this answer.
Nmap is best launched from inside Metasploit. See the Metasploit Unleashed (free training available from Offensive-Security) section on Port Scanning for more information. If the target IP address is available from the global Internet, then I suggest you also check out MyIPNeighbors and SHODAN , which are incredibly resourceful for this sort of ...
You can use this via nmap -sU --script smb-vuln-ms08-067.nse -p U:137 <host> or nmap --script smb-vuln-ms08-067.nse -p445 <host>. nmap --script smb-os-discovery.nse -p445 127.0.0.1 will detect the host & protocol, you would just need to use grep to see if it's still smbv1 supported.

Nmap probes the Zombie to determine its IP ID sequence class and the current value it is using. Nmap then sends TCP SYN packets to various ports on the target, but spoofs the source address to be that of the Zombie. During the scan, Nmap continually probes the Zombie to find out how many packets it has sent. Expecting one packet per probe, if ...
