This is the fastest Internet port scanner based on Robert David Graham's masscan tool: https://github.com/robertdavidgraham/masscan
It can scan the entire Internet in under 6 minutes, transmitting 10 million packets per second.
It produces results similar to nmap, the most famous port scanner. Internally, it operates more like scanrand, unicornscan, and ZMap, using asynchronous transmission. The major difference is that it's faster than these other scanners. In addition, it's more flexible, allowing arbitrary address ranges and port ranges.
NOTE: masscan uses a custom TCP/IP stack. Anything other than simple port scans will cause conflict with the local TCP/IP stack. This means you need to either use the -S option to use a separate IP address, or configure your operating system to firewall the ports that masscan uses.
$ git clone https://github.com/pkdavies/masscan-snap.git
$ cd masscan-snap
$ snapcraftSimply call the snap package:
sudo snap install masscan_*.snap --devmode --dangerous
And then run it normally:
# masscan
usage:
masscan -p80,8000-8100 10.0.0.0/8 --rate=10000
scan some web ports on 10.x.x.x at 10kpps
masscan --nmap
list those options that are compatible with nmap
masscan -p80 10.0.0.0/8 --banners -oB <filename>
save results of scan in binary format to <filename>
masscan --open --banners --readscan <filename> -oX <savefile>
read binary scan results in <filename> and save them as xml in <savefile>Follow the examples in Robert's repository.
