Hi, today’s tip is an Nmap option. It’s nothing extroardinary but I haven’t been aware of it for years and the day I stumbled on it, it has simply changed my life.
So I’m sharing it with you today on the off chance that you’re not using. To scan all TCP ports of a target, I used to do:
nmap -p 0-65535 192.168.217.2
Since I have the memory of a goldfish, I had to look up the maximum port number (65535) every single time! Enter the following option:
nmap -p- 192.168.217.2
-p- is equivalent to
-p 0-65535 and a lot easier to remember.
Please let me know if you have a comment, other Nmap tips, requests for tutorials, questions, etc.
See you next time!
