#Nmap vs zenmap plus#
The scan can be said to be a “Intense scan plus UDP” plus some extras features. It is however not so complicated once you take a closer look at the options. This scan has a whole bunch of options in it and it may seem daunting to understand at first. Slow comprehensive scanĬommand: nmap -sS -sU -T4 -A -v -PE -PP -PS80,443 -PA3389 -PU40125 -PY -g 53 –script “default or (discovery and safe)” This means it will issue a TCP SYN scan for the most common 1000 TCP ports, using ICMP Echo request (ping) for host detection. It will traceroute and ping all hosts defined in the target. Use this option when you need to determine hosts and routers in a network scan. Quick scan plusĬommand: nmap -sV -T4 -O -F –version-light Īdd a little bit of version and OS detection and you got the Quick scan plus. Scan faster than the intense scan by limiting the number of TCP ports scanned to only the top 100 most common TCP ports. Ping scanĭo only a ping only on the target, no port scan.
Usefull if the target is blocking ping request and you already know the target is up. Just like the other intense scans, however this will assume the host is up. The 1000 most common protocols listing can be found in the file called nmap-services. Normally Nmap scans a list of 1000 most common protocols, but instead we will in this example scan everything from port 1 to 65535 (max). Because this scan includes UDP ports this explicit definition of -sS is necessary. The -sS option is telling Nmap that it should also scan TCP ports using SYN packets. Same as the regular Intense scan, just that we will also scan UDP ports (-sU). This comes from having a pretty fast timing template (-T4) and for using the -A option which will try determine services, versions and OS. With the verbose output (-v) it will also give us a lot of feedback as Nmap makes progress in the scan. It will make an effort in determining the OS type and what services and their versions are running. Should be reasonable quick, scan the most common TCP ports. The presetsīefore we go into the different options in use I will make a brief explanation of each of the presets that come with Zenmap.
Big thanks to Fyodor for creating and maintaining such awesome software. Nmap was created by Fyodor (Gordon Lyon, twitter, about) and has been actively developed since 1997. Some of the scan types are kind of obvious, however they may not be to everyone. It comes pre loaded with 10 different scan types which we will take closer look at them in this article.
#Nmap vs zenmap free#
Zenmap is the GUI for the very popular free port scanner Nmap.
