I need help with nmap

Well, i've read lots of manuals, but I still don't understand how does nmap work.

I would like to scan a specific range of IPs, for open UDP and TCP ports, let's say:

From 2.249.250.200 to 3.2.1.2 (random IPs)

At the same time, i would like to print the results to a file called "bin"

I know I can scan from 0.0.0.0 to 0.0.0.255 (for example) typing "0.0.0.*" but what about a specific range of IPs like that?

Also, how do I scan single IPs? I think it's "IP1;IP2;IP3;...", but i'm not sure

u can use this syntex  :

nmap   scantype (-sS , -sT ,-sP .) -v(verbose mode) -T(1 or 2or3 or 3or 4or 5 is the time ) -oX or -oN (output )  ip/range

Thank you, but what's exactly the way to make a range? IP1-IP2 should do the trick?

Haha, thank you, I'll write the file.

Also, I find nmapfe even more confusing than the console XD I have just started in the Linux world, an my first distro was Linux Mint, so I want to learn things, and I want to learn how does the console works, and its commands.

Re: I need help with nmap

nmap -A -T5 -p 1-65535 ip1 ip2 ip3 ...

# -A   flag will get the service and details
# -T5  is to be faster
# -p 1-65535  selects all ports (they are limited)

you can use more wildcards

this is an example:

nmap 192.168.0.0/16 10.0.0,1,3-7.0-255
