Nmap & ncat All In One

Nmap & ncat All In One

https://github.com/udacity/course-ud303

https://nmap.org/dist/nmap-7.30-setup.exe

You'll be using Git to download course materials from the Github repository https://github.com/udacity/course-ud303. (You don't need to do this yet.) You'll also use it as part of an exercise on deploying a server to a hosting provider.

Nmap

You'll also need to install ncat, which is part of the Nmap network testing toolkit. We'll be using ncat to investigate how web servers and browsers talk to each other.

Windows: Download and run https://nmap.org/dist/nmap-7.30-setup.exe
Mac (with Homebrew): In the terminal, run brew install nmap
Mac (without Homebrew): Download and install https://nmap.org/dist/nmap-7.30.dmg
Debian/Ubuntu/Mint: In the terminal, run sudo apt-get install nmap
To check whether ncat is installed and working, open up two terminals. In one of them, run ncat -l 9999 then in the other, ncat localhost 9999. Then type something into each terminal and press Enter. You should see the message on the opposite terminal:
