In this quick post, I would like to explain about Nmap , which is famous for port scanning.
Port scanning to someone else’s server can be considered an attack, so be sure to do it on your own lab server.
Perform port scan by specifying IP address
vagrant@vagrant:~$ nmap 192.168.123.123
#It is also possible to specify a range of #ip addresses for scanning
vagrant@vagrant:~$ nmap 192.168.123.123-130
Option which we can use
I think that this tool is useful for problem solving, but please be aware that it can also be used dangerously.
