I’m a complete newbie, so sorry in advanced if the answers seems to obvious, but I could need a hint into the right direction. Currently I am working on the NETWORK ENUMERATION WITH NMAP module, and I’m stuck literally on the first module.
The Question is: “Our client wants to know if we can identify which operating system their provided machine is running on. Submit the OS name as the answer.”
I tried several commands for example like:
sudo nmap 10.129.2.80 -p 10001 -O -D RND:5 --disable-arp-ping -Pn -e tun0
as the Answer I got Linux, but if I type it into the answer field, I just get an Error (I tried every port and also the -S but this also does not bring me very far)
Already saying thanks in advanced for everyone taking his time to read and answer this
